Called Michael from Cornerstone Plumbing in the morning for a substantial exterior leak at my house and he had someone there by lunchtime. Joseph located the leak and got it repaired quickly and efficiently and he did not stop for a break until the work was done. This was the second time Cornerstone has responded right away to a plumbing emergency for me. They are definitely my plumber of choice!

First and foremost, I would like to express my sincere gratitude to Mr. Michael for his exceptional assistance. The incident occurred at dawn on Sunday when the water heater tank suddenly began to leak, leaving us without water and facing a challenging situation. Aware that it would be impolite to disturb anyone on a Sunday, we hesitated to reach out for help. However, to our delight, Michael graciously answered our call with kindness on Sunday afternoon and offered his assistance. We were immensely relieved when he assured us that he would come and resolve the issue promptly on Monday morning.True to his word, Michael arrived promptly and efficiently replaced the water heater tank, resolving all the problems we faced. Throughout the process, he displayed remarkable kindness and demonstrated a high level of professionalism. I am immensely grateful to him for his timely help, particularly during the early hours of the morning.I sincerely wish Mr. Michael and his business prosperity and an abundance of positive experiences in the future. Thank you once again for your exceptional service and assistance.

Called Michael when needed a new hot water heater. Impressed by his reviews and took a chance. He and Joe were awesome! Answered all my questions. Got me setup that morning and for several hundred less than the “big” boys. Give him a shot he won’t disappoint!

I called Michael on Saturday morning to inquire about the installation of a new water heater to replace my 17 year old water heater. I had off from work on Monday and he was able accommodate my schedule and install the water heater then.They arrived promptly at 8 am and immediately went to work. They did an outstanding job. Michael and his assistant were professional, personable, and took care not to damage the carpet and walls as they brought the old water heater out and the new one in. They were completed and cleaned up and out the door by 9:30 am. I highly recommend them for all your plumbing needs and will certainly use them for all future projects.

Exceptional service! Spoke to Michael one morning, gave him the go ahead later that afternoon, my water heater was installed first thing the next day! Less than 24 hours after first contact. Took him less than 2 hours to get it all done and at a super price.

Micheal responded quickly to our inquiry with a competitive rate. He also came out quickly and had out water heater replaced and up to code in no time. Very friendly and professional.

Review 12 (2021-03-16 - Rating: 5)
Michael is awesome. He was able to come out the same day when we starting hearing strange noises from our hot water heaters. He was extremely honest and not pushy but made some very realistic recommendations for our heaters that are 14 years old. His price was extremely fair and he was able to do the work in a few days. Literally was finished with the job in 2 hours - I wish every contractor worked this well!! FANTASTIC experience and I highly recommend him.

Michael impressed us with his fast response time and his honest pricing. I put in a request for installation on Angie’s list and he called within 4 mins and was at our house the next morning less than 12 hours from our call. He used quality parts and did not nickel and dime us like the competitors we called tried to. Thank you again!!!

Reputable, on time, and only charges for what I need. No spin. No grift. Just honest hard work they stand by. Thank you Cornerstone.

We found good ratings for Cornerstone under Kudzu so we decided to give them a try. We are very selective about who we hire to do work and have very high quality standards. We got a new sink and had a hard time connecting it to the garbage disposal. Michael was able to rework the plumbing and eliminate some unnecessary pipes, giving us more space which was awesome. He was very personable, professional, punctual, knowledgeable, and does his work well and very efficiently. His rates were reasonable and we now have a go to company for all our plumbing needs. Highly recommended.

I received many quotes over the phone to replace my Water Heater. Michael Vasquez with Cornerstone responded immediately. He gave me a ball-park estimate over the phone and then firmed it up after I had sent him pictures. He was one of the lowest estimates I received and it was very reasonable. He was VERY responsive to me throughout the entire process. Answered all of my questions and gave me a heads-up when he was going to arrive. He even fixed some of the cut-corners that were made by the builder of the house! I am VERY impressed with them and will always reach out to Cornerstone first for any of my Plumbing/HVAC needs!

My water heater died on Friday night. Ive never had to replace once so I had gone to home depot on Saturday and got on their list for a call on Monday. On Monday morning, I checked Angies list and called Mike. He answered my call right away and was at my house within a few hours with a new water heater. He and his assistant were very professional and friendly. They installed the new water heater and Mike also checked my shower which was leaking to the floor below and made a quick adjustment to the drain which may have fixed it! (Still need to run water to find out.) No extra charge for the shower check.He charged exactly what he quoted on the phone. I would highly recommend their service. Still havent heard from Home Depot.

Michael the owner And his 2 helpers did an excellent job!They were here when they said would be. Michael takes pride in his work and it showed. His prices are excellent no overcharging! I highly recommend Cornerstone Plumming😊

Review 24 (2021-04-15 - Rating: 5)
We needed help in the winter when our unit stopped heating the air. Cornerstone came out to check out the problem ASAP and had it repaired the same day. Better than the other mainstream companies out there there that overcharge and hassle you with extra expenses. Michael came out himself and made sure the job was done right. Very friendly customer service forward company. Would recommend 100%.

Review 25 (2018-07-05 - Rating: 5)
We needed to have our entire HVAC system replaced. Michael gave us several options and prices, along with plenty of information for making an educated decision. His crew worked efficiently and answered all of our questions. Whenever we need additional information, Michael responds to our texts and emails in a timely manner. We are very pleased with the work that was done.

Review 26 (2023-06-06 - Rating: 5)

Wow! What a refreshing change. We called Michael to help us with rattling pipes and a broken tank. Turns out they were both minor fixes and he recommended easy DIY solutions--he didnt charge us a penny. I almost cant wait for something else to break so I can hire this company. A first for everything!

Thought replacing the hot water heater would be a three-day event, but Cornerstone came out and did everything same day. The tech was courteous, helpful, cleaned up, and was on his way in a couple hours.

Review 35 (2015-08-15 - Rating: 5)
We had a shower leaking into the basement, and a outside spigot that had a leaking valve. Michael was prompt to fix the problems and did an excellent job. He recommended we change our approach to completing the basement that would save several thousand dollars (than he could have made) because it would be an unnecessary expense with little value added. Thanks Michael, we will keep you in mind with all of our future HVAC and plumbing needs. Speaking of, I am about to call you.Elise and Ryan Moore

Review 36 (2014-09-10 - Rating: 5)
I had a pump fail over the weekend resulting in a flooded basement. Michael talked me through steps to take care of the situation and possible causes. He later came by to inspect the equipment and found that it started working again by clearing some of the pipes. He gave me instructions on what to watch out for in order to monitor the performance going forward and did not end up charging me for the service visit. Honest and knowledgeable service - a class act to work with. Ill definitely keep him in mind for any future HVAC or plumbing service needs.

Review 37 (2023-03-02 - Rating: 5)
Fast and professional service. His quote was much more manageable than other ones I got. I would recommend Michael and his service to my friends and family.

I really appreciate the honesty in this company. They go above and beyond for their customers. I had just painted my deck when two days later a pipe burst under it. 3 companies were going to tear up the deck and this was the only one willing to dig under instead. I had them replace the broken pipe and then come back and replace old water heaters. The quality of work and character is great! I highly recommend!

Cornerstone was fast, communicative, & honest about our options. They helped us make the best decision for our home. We ended up replacing & upgrading the entire HVAC system but there was no pressure to do so. All options were carefully explained & everything else about the house was taken into account. I highly recommend these guys if you want someone you can trust with making big decisions for your home. Its nice to feel confident about any kind of major repair & we feel good, especially with good a/c!

Woke up to a leaking hot water heater in the basement. Quick Google search for plumbers near me and Cornerstone popped up. Searched for reviews on the company and saw positive reviews and being in a time crunch I went ahead and asked them to do the replacement job. Mike was very upfront and 6254 Stillwater Place eat in everything he said. Called to let me know when he was on the way, was prompt and professional with the install and the removal of the old hot water heater. Glad I found Cornerstone. I now have a local plumber I can count on.Great job Mike.

I called the company on a Saturday (New years Eve) when many other companies would not respond. I had water leaking all over vet my basement and needed help now. He listened and responded while assuring me everything is going to be alright today. He gave me a quote that was very reasonable and stuck to it. His responsiveness was great and he was here within the hour ready to replace my water heater. My water heater is replaced, he explained everything about the operation of it and gave me a guarantee. Great personality and professionalism. I would definitely recommend anyone needing his services to contact the company. He made our family’s day and relieved our stress. Thank you Michael.

Professional, great communication, quick turnaround. I found Cornerstone Plumbing through Angis list and Michael was very prompt to reach out. He was knowledgeable and accommodating. Some other plumbers that I called wanted to charge a fee to come out and told me they wouldnt know how much the total would be until they came out. He gave me a quote and stuck to it. Honest and fair pricing. Would recommend!

Theyve been here for 3 unrelated problems over the last few months. Each time theyve responded immediately, arrived the next day first thing, and taken care of the problem in a single visit. Great quality. Great service.

Review 70 (2019-09-12 - Rating: 5)
Outstanding service, and better than competitive pricing. This is the second time Michael and crew have bailed us out, last year for a water heater, and today for a complete HVAC replacement. Michael walked us through all our options, after repair/band aid was not an option. Highly recommended. Fortunately, there isn’t a whole lot more to go south on us, but if it does, I know who we will call.
