It is so nice to work with a professional that is courteous and friendly as well as knowledgeable in his field. Mark was able to fix an issue we had with our water main shut off valve in a timely manner. He was also able to diagnose an issue with the water heater valve that we weren’t aware of at the time.

Mark is so amazing! As new homeowners, my boyfriend and I know very little about plumbing. Mark came to the rescue and not only fixed our garbage disposal/shower issues, he was super informative about the whole process. He made sure we had all the information we needed and was so patient and helpful. His pricing is very reasonable and he is a delight to work with.We will one hundred percent be using C4 for any future plumbing needs. 10/10 highly recommend!

Mark is incredible. We had a gas leak that he accurately diagnosed. He got us scheduled quickly, and communicated with us at every step of the way. He went above and beyond throughout the whole project. It was clear he genuinely cared that we were safe in our home. He worked long hours in order to help us get back into our home quickly. Denver water had to come by for a separate reason and when they saw Marks gas line work, they couldnt stop complementing what great work he had done. We recommend him 100 times over and will use him for all of our plumbing needs going forward.

Mark did an excellent job fixing our plumbing issues in our kitchen and basement! He was thorough and explained the work really well to the point that I was confident in the decisions I made to make sure I was being overcharged. He was super friendly as well! We will definitely be using him for any future plumbing issues we have!

Mark Canty is by far the most affordable and professional plumber I’ve done business with. We are delighted to have found him and will do business with no one else.We a currently dealing with a water loss and after running across a plumber who did work for us that was out of code, Mark came in and rectified the work at a very reasonable price.In fact, his price and knowledge led my wife and I to decide to replace every pipe in our home while the walls were open to have a peace of mind about our water lines in our home.Mark also helped us recoup the $1900 we paid the previous plumber who completed work that was a code violation. Within seconds of stepping into our bathroom, he noticed the violation. This man knows his stuff!!While staying at an airbnb while our rebuild is in process, Mark also helped us with a sink we cracked due to a faulty glass soap dispenser. Seeing every thing we were going through, he didn’t charge us to replace that sink.This guy goes above and beyond for his customers and makes sure your work is done right, and walks you through any concerns he sees in the process of any repairs.This is a stand up guy who is honest, hardworking, and stands by his work!

Mark went above and beyond as usual!Timely, professional and got us back up and running without a Hitch.Very thankful for Him!

Excellent work, on time, finished on time, he went the extra mile to cover white carpet so no dirt or marks on floor. Gave great advice on softener and had the foresight to replace a couple older valves without asking and he was close to half of what the ‘big shops’ thought I needed to pay. I highly recommend!

After the first time I called then used C4 Plumbing, I came away very pleased. When I was recently in need of a repair, I did not hesitate to use them again. I was equally pleased the second time and will continue to use them in the future for all plumbing needs.

Review 10 (2024-05-11 - Rating: 5)
We called C4 to evaluate a water heater that a home inspector flagged as a potential problem. Mark was courteous, prompt, and honest. Though he could have tried to convince us to install a new water heater at considerable cost, he quickly determined that our water heater was in great shape and that the home inspector had misdiagnosed the health of the water heater. Mark didnt even charge us for the service call! We would certainly contact C4 again for any plumbing needs.

Review 11 (2024-07-12 - Rating: 5)
Mark was able to quickly work us into his schedule, addressed the issue, sent me the estimate and confirmed direction before starting and sent me pics after. Great experience!

Review 12 (2023-11-21 - Rating: 5)
Mark was great to work with! Our main water shut-off was leaking, and Mark was able to provide next-day service. He showed up right on time, worked quickly, and left the work area tidy. Mark was friendly and professional from start to finish, so I will definitely be calling C4 Plumbing the next time we need plumbing services.

Hot water heater went out this week. Mark C. came out to my house and gave me a quote the day it happened. Install was done the following morning. Professional, friendly, knowledgeable and great quality of work done. I paid pretty much what I was expecting for a hot water heater and install labor. I highly recommend!

Mark was awesome and explained things thoroughly as he was doing the job. Very professional. Will 100% use again.

Mark came and fixed a pipe in our home. He had to investigate a bit to find the root cause of the leak but was very good at finding and fixing the problem. He was very professional and courteous and we would definitely use his services again. Id be happy to refer him to others.

Mark did good work on replacing sump pump and the cost was reasonable.

Quick response, explained everything, no hidden charges, on time, very clean and extremely personable. I highly recommend C4 plumbing.

Review 18 (2024-02-08 - Rating: 5)
Mark was prompt (responded to my initial request within minutes), professional and thorough in his explanation. I always worry that I wont understand technical details of things my husband handles; but Mark took time to explain things on a simple level. He even let me borrow one of his hoses for a week to make sure my water heater didnt continue to leak after the tank busted. What a kind act!

Review 19 (2023-09-20 - Rating: 5)
Service was great! Mark was super kind and fixed my leak the day I called in. I appreciated how they sent a photo of the plumber who was coming. Clean, comfortable, and would definitely use them again!

I had a water leak at the base of an upstairs toilet and Mark came out the next day. He took the time to show me the problem and gave me enough info so that I could do a similar job myself. He was also very efficient, neat and courteous.You just have to let this guy do your next plumbing job, especially if you live in Aurora. Hes awesome!

Mark does professional work! He even came out on a Sunday to take a look at our water heater leak. Got a new one installed the following morning. Highly recommend!

Mark our palmer was very efficient, very kind, quick respectful and courteous C4 plumbing will probably be or go to plumbers from now on. We really appreciate them coming out on the holiday weekend.

Review 24 (2022-12-05 - Rating: 5)
Josh was fabulous as always. On time, personable and efficient. I had him uncap a water line to my fridge and install a new connector. He is amazing. A few months back, I called C4 to install a new washer and the spigots had to be replaced. They sent Josh and he was amazing. I requested him for the current service as well. I’m sure all the C4 techs are great, but Josh goes the extra mile.I highly recommend C4. Their pricing is very competitive and the work is top quality.

Review 25 (2023-10-05 - Rating: 5)
We chose C4 because they advertised free estimates. We werent expecting much more than a quick look. I used a big national company in the past and they charged an arm and a leg for the smallest task. Mark C came in and after inspecting both of our issues, one minor, which he fixed on the spot, and one major, he thoroughly explained everything as well as provided tips on standard upkeep. He was very professional and knowledgeable. Now that we found them, we are going to finish a few projects we had been putting off.

Review 26 (2023-09-08 - Rating: 5)
Recently my water heater completely broke and I was looking for local plumbers in the area who can help. Im so thankful for choosing C4 Plumbing. Mark was not only able to look at the water heater on the same day, but also was able to replace and install a new one on the very next day. If you want fast and professional help with your water heater, I can not recommend enough this business.

Review 27 (2023-10-31 - Rating: 5)
Great business and have been nothing but satisfied with the work Mark does. Reasonably priced compared to others. Prompt responses. Transparent and does a good job of explaining whats/whys. Also, doesnt charge a fee to come check out your issue which goes along way. Highly recommend.

Can say enough good things about C4 Plumbing. Mark installed a water heater and brought everything up to code. Great price and great job. I highly recommend Mark and C4 Plumbing for all your plumbing needs!

Review 29 (2023-01-24 - Rating: 5)
After working with C4 twice in the last year I felt it was time to post a review! In March of 2022 our heater went out and it was freezing cold from what I can remember. We called around and C4 was the only company willing and able to send someone out same the same night. They were able to implement an inexpensive fix and had the heater up and running that night, much to our relief. They did warn us that our furnace was original to the home which was built in 2001 and was probably going to need to be replaced sooner than later. Fast forward to last week, we woke up to the furnace struggling and found their number to call again immediately. They were able to schedule us in the next two hours. After evaluating, gave us options on repairs that we decided against as that cost to repair individual parts was going to be about half the cost of the new furnace. They were able to get the furnace replaced, old one removed and the heater back on same day again. My husband worked directly with Josh both times and I’m just so grateful that they have been so reliable and easy to work with. We will continue to contact them for our heating, cooling and plumbing needs and I 10/10 recommend them to anyone!

Review 30 (2022-09-17 - Rating: 5)
Josh came out and gave me a quote for some AC work we needed done. The prices were very fair so I went ahead and booked an appointment for the following day. I had told Josh that we had a funeral to attend that day so our timing was tight. He instead gave me a call that night saying he could come and get it taken care of so we were not pressed for time our funeral. He was professional, knowledgeable, kind and went completely out of his way to accommodate our situation. I will for sure be using them again and highly recommend their services.

Review 31 (2022-05-05 - Rating: 5)
We had a great experience using C4. They were incredibly responsive. Within a day, Marcus was able to come to our house and address a leak. Rates are very reasonable. It is a relief to find reliable and fast plumbing services. I highly recommend C4.

Review 32 (2021-03-18 - Rating: 5)
Our first time using C4 Plumbing and definitely wont be the last. Mark and his team were great in all aspects. He constantly emailed or called us for updates throughout the project. Highly recommended and you wont be disappointed!

Review 33 (2023-09-09 - Rating: 5)
This was our second time using C4 Plumbing. Mark was very helpful and informative and was able to fix our water hammer and diagnose/resolve the leak in our basement. Thank you for the great service!

Review 34 (2020-01-15 - Rating: 5)
Mark was out in no time and was able to quickly diagnose and fix a leak that was coming down from the master bedroom upstairs to the ceiling below. He was very nice, professional, detailed and most importantly a life saver for coming out after regular business hours to fix the problem. Mark was straight forward and honest with his plans for repair and didn’t try to run up the cost of the job. I will be using and recommending Mark and C4 Plumbing for all of my plumbing needs.

Review 35 (2020-05-28 - Rating: 5)
Mark came to the house today to take care of a few things that I have been putting off for some time now. He was very informative on how to best handle the repairs and I felt it was a tremendous value as well. It is always wonderful to meet great people who really take pride in doing a wonderful job. I would highly recommend C4 Plumbing and will definitely be using them again when needed. Thank you Mark!!

Review 36 (2020-06-12 - Rating: 5)
Mark with C4 Plumbing did the plumbing for our basement that we are finishing.....adding a sink for a wet bar, moving some pipes around for us, and all the plumbing for the full bathroom. He did a great job! Everything works and looks great. He cleaned up after himself everyday. His prices were fair and his work quality great. We will definitely call Mark again if we have need.

Review 37 (2020-03-24 - Rating: 5)
Mark with C4 plumbing came out to install a whole house water purifier for us. He was professional and did excellent, clean work. Really nice guy as well. We have remodeled our whole house since we bought it five years ago and have used quite a few subs so we have had our share of good and bad, sadly more bad than good experiences. I would not hesitate to use Mark again, in fact he will be installing our hot water heater when needed and a new toilet. My husband was in the commercial construction industry for 40 years, he knows good subcontractors when he sees them and was really impressed with Mark & his quality work. If you have several to pick from, choose Mark with C4!

Review 38 (2022-06-28 - Rating: 5)
Highly recommend!!!! Marcus came out to replace a valve on our new house leading to the sprinkler system (which he did a great job of!). What really surprised and wowed both of us was the second trip, though -- the system still wasnt working, and after about half an hour of diagnosing the issue he was able to locate a valve hidden (and barely reachable) behind drywall that had recently been put up, saving us hundreds of dollars if wed had to tear out the drywall and pay to have it redone. SOOO thankful that we called him! Very courteous and professional!

Review 39 (2024-09-23 - Rating: 5)
Mark with C4 did an amazing job and helped diagnose a difficult issue. He had to cut into the drywall, but it is clear that his knowledge and experience allowed him to minimize the number of cuts and are easily patchable. I really appreciate how quick he was able to come out and get me taken care of. Thank you, Mark!!!

Review 40 (2022-05-24 - Rating: 5)
They came out on the same day and were very honest with us about what was going on. Our hot water heater was only a year old, from another company, and not installed properly causing the tank to crack and leak. I was very impressed with their warranty, and fast installation. The transparency of how they operate and honesty throughout the process was very refreshing.

I had such a great experience with C4 plumbing. I had a frozen pipe and Mark assistants me and got the job done so quickly. I will recommend C4 plumbing.

Review 42 (2018-03-30 - Rating: 5)
Mark was a pleasure to deal with. When I called, I got straight through to him and he was able to come out the following day. He explained the problem clearly, quoted me to fix it, and went ahead and fixed it the same day. I was happy with the price. Mark is a clear communicator and a nice guy. I would happily recommend him for your plumbing needs.

These folks are the BEST... genuinely, in the Greater Denver Area there is no better plumbing company, period. My wife and I had our master shower/tub go out at the beginning of COVID-19. For a while things were too uncertain and unstable to feel comfortable bringing someone out, and we have another working shower in the home, so it wasnt a priority. We decided to get it fixed a few weeks back, but had nothing but problems with the first company we called to come out - a recommendation from a friend. After two weeks of hassle and no work, we called C4.Mark - the owner - was the one to come out for the initial estimate. He was prompt and punctual, friendly, and direct. He explained what needed to be done, and kept us updated throughout. The work itself was completed by Jeremiah Quast, and he was equally fantastic. He was awesome with our dogs and kids - and really careful not to interrupt their distance learning. He got the job done incredibly promptly, and stayed exactly on-estimate. The work looks great, and our shower and tub are working better than when we moved in.I would HIGHLY recommend C4 Plumbing to anyone. Theyre seriously top-notch.

Mark was awesome! We had an emergency pipe leak last night and he was the only 24/7 that was actually 24/7. He was here within an hour and had it fixed within another. Super fast, friendly and explained everything he was doing. We would use him again in a heartbeat!

Review 45 (2022-05-22 - Rating: 5)
Marcus was on time and really great!! It was a water tank hose leak. It had happened before and the people I’d used had left a length of hose behind from that job. Marcus was extremely honest and asked if I had someone who I thought could fix it- I did- and he advised me in what to do. I was really amazed and very impressed. I will never use another company except for C4 again. 😊😊😊👍🏻👍🏻👍🏻

Review 46 (2019-03-24 - Rating: 5)
Mark is very courteous, thoughtful and knowledgeable. Hes the real deal as a plumber too. Our service was after hours so it was expensive. You may find less expensive plumbing repair companies in Denver but that you wont find a better, or more competent, plumber than Mark.

Review 47 (2022-05-05 - Rating: 5)
Recently had a shower drain fail and start leaking on our main floor ceiling. Marcus from C4 was incredible from start to finish. Great communication, timely and did a great job! Hopefully we wont have any more plumbing issues, but if we do Marcus and C4 will be our first call!

Review 48 (2021-12-17 - Rating: 5)
Had a great experience with C4! Had a pretty big leak in my basement and when I called C4 they had someone out there ASAP. Marcus was there within the hour and his professionalism and experience were beyond expected. Unfortunately I was out of town when this initially happened and someone had to meet him. But Marcus was sure to call me and explain everything in detail. He even came back to go over things again when I came home. Would definitely use C4 again and will be requesting Marcus for sure!

What an outstanding job Mark did for me turned out to be a little more work than either of us expected, but he got the whole thing completed and it’s a piece of art . Thanks , Mark

C4 was professional & efficient from my first phone call to the completion of the repairs. Nyzayah is absolutely incredible. He’s knowledgeable, kind, focused, and thorough. He was even a great role model for our son. We’ve already recommended him to our friends & we will certainly call them again.

C4 did a fantastic job on my townhome. They replaced all the shut-off valves on sinks and bathtubs. Installed faucets, and my hot water heater. Very reasonable price for the whole job. Mark was consistently very responsive, really nice guy to work with. I have him in my personal directory as my first contact for plumbers. Highly recommend this company.

Mark was right on time(+++), and very courteous and knowledgeable.My garbage disposer was not draining and I assumed it needed replacement.Mark took a good look and informed me it probably just needed to be unclogged and reset. After he did that he showed me how to do it myself if it happened again. On top of that, he did not charge me for the trip. I will definitely call him again for my plumbing issues.

Review 53 (2021-02-16 - Rating: 5)
Freezing temperatures caused a pipe to burst in our laundry room. Called a number of plumbers but C4 were able to get to us in the shortest time frame. Plumber was punctual and gave us an estimate before work was started. Excellent communication and they made sure we understood what was being done to fix the problem as well as mentioning things that could be done to avoid this issue in the future. Work was fast and cleaned up very well. I highly recommend their services

I contacted C4 plumbing through Facebook when I noticed two of my hose spigots were broken. They promptly replied, set a date and tome to come out and gave me a call when they were about to arrive. I appreciated knowing what they planned to do and what it would cost before work began. Mark was very professional and kind and I would recommend him.

Excellent and efficient customer service! Mark went above and beyond to ensure our family had running water over the weekend, saving us the expense of a hotel. We got multiple quotes for our main water break repair and Mark beat them all! His prices make it affordable for hard working families on a budget. We appreciate his fast response and master knowledge in his field. Mark will defiantly be are go to guy moving forward for any plumbing repairs and upgrades! Thanks Mark!!!!

Mark arrived at our business after hours ready to help and full of answers. We had been struggling with our water heaters for some time and Mark installed and corrected our issues promptly and explained every step and procedure to where anyone would understand and be confident that their issue was going to be resolved.

We woke up one morning with water dripping from our kitchen ceiling. C4 Plumbing was the only company to answer our calls and they were able to come to our house the same day. After assessing the situation and explaining the problem (a valve from our washing machine we were replacing upstairs), they didn’t even charge us for the visit. Mark was kind and professional the whole time. We will be calling them again, and would highly recommend this company!

Review 60 (2018-05-01 - Rating: 5)
Absolutely amazing customer service from the C4 plumbing team. They responded to our request for a water heater replacement late at night. Mark arrived the next day and was prompt, thorough, and ensured that we would be all set for installation the next day where he went above and beyond on the installation as well as answering other plumbing related questions we had. If you’re looking for a fair price and unbeatable customer service, look no further.

C4 is awesome! Both times I have used them they are super quick to respond and to get here. Once was on a Sunday! This recent one was to fix the valves on my washer and dryer. Nyzayah Dean was super professional, helpful and just overall wonderful. I cannot recommend these people more!

Mark came to repair my steam shower but when he entered our storage room he smelled a slight gas leak. He could tell it was a small leak but told me to call Excel. I did and the gentleman from Excel could not smell it. Even his leak finding device had a hard time finding it. He had to remove the side from the furnace and finally found the leak. Needless to say, both the Excel employee and I were very impressed with Mark! I will be using him for the shower and I’m sure he will do a great job!

Review 63 (2023-10-11 - Rating: 4)
Answered the phone, arrived within 2 hours, fixed the leak. I do however wish they would have replaced both water heater supply hoses instead of just one for $399. If the one had a pinhole, how far behind is the other one?

Review 64 (2019-02-15 - Rating: 5)
Mark was so great. He came out at 8 PM on a Sunday to help us with a backed up sewer line. He was able to get the block cleared and then give us what he thought our next steps should be based on the things he discovered while snaking out the line. He explained everything clearly and made sure we understood things before he left. thank you Mark!

I wish I could give 6 stars, but that is not an option. Mark and C4 plumbing are very professional, knowledgeable, responsive, and friendly which helped with my situation. My house had high water pressure, 88psi, and caused my dishwasher to leak for an unknown period of time. I called after hours (11pm) and they answered, and set up an appointment for the next day.Mark showed up on time and shut found the issue, and he cut the water to the dishwasher since my shut off valve was broken as well from the previous owners. He also set me up with the right mitigation company to come dry out the kitchen.I called Mark back about 2 weeks later to install a PRV valve on my main line. While he was doing that he went above and beyond any plumber I have ever worked with. While he was at the house, he checked more areas where the high pressure could have been an issue and fixed what I didnt know need to be fixed at an EXTREMELY fair price.Thank you for everything you did for us, I would recommend Mark and C4 Plumbing to anyone!

Mark is phenomenal. He is the definition of a professional. Shows up when he says he will, is very thorough and explains everything. His pricing is also the best Ive found. He came to give me a bid on my basement and ended up inadvertently finding a dangerous situation with my water heater which he resolved the next morning for $1000 less than anyone else. Highly highly recommend him.

The repairs were quick and efficient. He was extremely friendly and knowledgeable, and we could tell he was looking to do a great job! I called for service after 8:00pm, he was out to the house quickly and completed all repairs without obnoxious costs. I will absolutely call C4 Plumbing for any plumbing needs in the future. THANK YOU!!

Mark was very professional, efficient, competent, and pleasant to work with, being flexible to work around construction workers and to accommodate my schedule. The remodel job entailed cutting out drywall and drilling through studs to reconfigure the plumbing, and the end product was very satisfactory, even to the point of his trimming out the drywall to expose the stud and make the drywall repair much easier and cheaper. His office staff was also courteous, efficient and timely. It was wonderful to be able to trust that Mark would do a good job without my continual supervision.

Marc, as always did a great job, fast and thorough, explaining what he was doing throughout. I would not hesitate using him again.

Review 71 (2019-12-09 - Rating: 5)
We had Mark come out and move our kitchen faucet plumbing over about 18 inches to accommodate a kitchen remodel. Over the course of our job, we had him move the plumbing, install a faucet, drain, dishwasher, garbage disposal, and run a new copper water line to the fridge/icemaker. While performing all this work, they also saved us from a flooded basement when it was discovered, just in time, that our main water line and cut off valve were badly corroded and leaking. The stars aligned for them to be there to notice it at all. A fair price, great workmanship, and friendly service? Cant ask for more. I would, and will, gladly call Mark and C4 plumbing for all our service needs. Glad to have a dependable household plumber. Thanks Mark, and team!!

Josh and Marcus went above and beyond for my Family and I in an emergency plumbing situation today.They worked from 4PM until 7PM, to get us into a position to enjoy Christmas with the basic aminitty we all take for granted called PLUMBING!Speaking to Josh and Marcus reminded me of speaking to long time friends, great Guys who we will hopefully have in our corner when the need arises in the future.

Just had Mark from C4 plumbing come to the house. May I say polite, professional,and very honest. I have dealt with other plumbers before. But have never had an experience like today. In my mind the job was rather large. He got the job done very quickly. Was very clean. Also beyond affordable. I will never call another plumbing company again. I will be calling C4 exclusively. Thank you Mark.

I had a great experience with C4 Plumbing. They were one of the few plumbers that made time for me in the late hours of the night and addressed the issue immediately upon arrival. Because I needed owner approval, they didnt even charge me for more than just the after hours fee. Highly recommend!

From first call to final invoice this was easy mode. Marcus showed up on time and ready to work. He shamed the previous plumbers bad attempt, going above and beyond making the install shine. Its right on the front of my house and looks GREAT.10/10, will hire again.

We had an old rotten line break that was feeding the washing machine. Called about a dozen places and Mark was the only one who could come out late the same night and fix it. He had it fixed and the water back on in an hour!! Super professional quality work that I would recommend to anyone.

Review 79 (2020-07-28 - Rating: 5)
Best plumbing service in the Denver metro hands down! Their work is top notch and Mark is one of the most professional people in this industry that I know! I wouldnt use anyone else to do my plumbing work at my house! Definitely recommend C4 Plumbing!

Josh A. came out on a Saturday was able to locate issue within 10 minutes and swapped out my compacitor within 15 minutes and my AC was up and running right away. I was really impressed with him. Thank you guys for helping me out especially on a record hot day!

Review 81 (2019-04-27 - Rating: 5)
We had a Saturday evening plumbing emergency (sewer water backing up into our basement). After calling about 10 companies that didn’t answer or didn’t have availability, C4 came to the rescue. They had a technician available in 2 hrs, and he ended up arriving 90 min later. Mark got right to work on our main line, and had to get a longer snake due the distance to the tap. Even though it took him much longer than normal and he had to use two machines, he did not add any additional charges. He was also friendly and explained everything that he was doing. I would certainly recommend this company and will likely use them in the future.

I highly recommend C4 Plumbing to anyone who is interested in hiring a company that is knowledgeable about plumbing issues and willing to explain the issue prior to proceeding with the solution.Mark did a great job walking me through the problem and the steps he would take to correct it. Everything he said he would do, he did, and the plumbing concerns were taken care of. If you are looking for a plumber, be sure to reach out!

Review 83 (2019-08-06 - Rating: 5)
We had a bad water leak in our home late at night. Mark of C4 got to our home in 30 minutes. Everyone else we called said it would take them at least 4 hours (one outfit, after saying 4 hours, called us back and said 6 hours). Mark fixed out situation and even educated us on maintenance and other issues in our home. Even in that bad situation, C4s customer service left us feeling good. Our only regret is that we cannot give 6 stars.

Mark installed an expansion tank and repaired a leaky shutoff valve to get my home ready for sale. We scheduled for the first slot of the morning, 8-10am and knowing that I was on a tight timeline that morning, he showed up at 7:40 and I received a call letting me know he was there and ready, if I wanted to get started sooner. Hes always extremely punctual, does great work, and is willing to share what hes doing and why! Additionally, his prices blow everyone elses out of the water (pun intended)! I dont even call any other plumbers now!

Review 87 (2019-04-06 - Rating: 5)
Great experience. We had flooding in the basement. We called all the big name companies Rooter Roter, Benjamin Franklin that say they provide 24 hour emergency service; they dont. We continued our search, and found C4 Plunbing, they took our information and said they would be there in 45 minutes. Mark was the guy that came out, did a great job, explained the work that needed to be done and gave us the estimated cost. When he finished, the cost was actually less that what he said it would be. I would strongly recommend this company

Late night toilet backup in the basement. Wanted to get the line cleaned out immediately as we were supposed to have a blizzard the following day. Called a handful of 24 hr places and none of them had openings until the following evening (during the blizzard)Mark at C4 Plumbing was on time, professional, clean, and also gave me some tips on keeping our sewer lines clean in our old house. Super super helpful and he was a life saver.I would highly recommend using C4 Plumbing and would call him again in a heartbeat.

Review 89 (2019-02-25 - Rating: 4)
Marc listened to my puzzle and after suggestion and more radical solution kept trying to find the root cause which he did. It was just finding a shut off vulvae which another person never found. Id give 5 stars, but he didnt really do any hard work so I cant really review that aspect. But he gave me peace of mind when an outside pipe sprung a leak. And he was real nice.

Punctual, affordable, accommodating! I had a shower that I needed to replace the shower cartridge and pressure control valve ASAP! Contacted at 11pm and they answered promptly and had Mark here at 8 A.M. the next morning to address and fix the issue! Great customer service and overall experience! Would highly recommend!

I have to rave about C4 Plumbing. We had an emergency come up Sunday night. I messaged them via Facebook and someone replied within 5 minutes and they were out at 7am Monday morning and here all day to get us taken care of. We have dealt with several contractors this year including a GC and his subs and a Landscaper and just had bad experience after bad experience. Mark and Chris were so attentive, knowledgeable, honest, and patient with our 2 year old that wanted to chat with them all day :) #beyondimpressed! Thank you C4!!

Review 93 (2019-07-29 - Rating: 5)
Id like to thank C4 Plumbing for helping me out late Saturday evening with a pipe leak. I had struggled with it for a few hours wondering why after shutting the main water valve I was still seeing water coming out of that pipe. In a panic, I started looking for a plumber that could come as soon as possible. I found C4 Plumbing and Mark came out that same evening to work on it. He was professional and did an awesome job with the repairs. He also showed me what other repairs I should think of getting done so in case I ever get another leak, my main water valve will work properly. He has great customer service and very knowledgeable in his field. I will definitely be calling him back for those other needed repairs and I would recommend him if you need any plumbing work.
