I am so impressed with Cornerstone. They helped me out in a pinch, and went above in beyond in helping with the service and being flexible with dates. Larry Harper completed the project, and was an excellent professional with a lot of detail in his work. He was very communicative and helpful throughout the process, even finishing earlier than expected. Will definitely use their services again.

GlenTommy were professional and first thing they did was get a walk through with me to ensure everything we paid for was on their work order. They arrived around 830am and were done by 3/30pm. They were doing electrical work before our bathroom is remodeled so it involved moving or replacing wires, adding a GFCI, installing new wiring for a ceiling fan.

Used Cornerstone Services today to replace all of our old smoke detectors. They showed up even earlier than they said they were going to be here . They were very good at explaining all they needed to do and what the cost would be before starting. Considerate of keeping everything in the house clean, even wore coverings over their boots . Thought that was impressive. They worked very efficiently and got everything done in a very timely manner. I will definitely use Cornerstone Services again.Actually used Cornerstone again the next day. Had a young man Canyon come out to do service on our furnace. Again absolutely a 5 star rating. Did the annual maintenance and made sure all was in great working order.Thorough and efficient.Everyone from Cornerstone that has come to the house has been exceptional. Highly recommend Cornerstone for anything you need done.

I have been using Conrenstone for about a year for house cleaning and service and quality has been excellent. Recently had them power wash my house as well, and it looks like new. Jason came out promptly to provide an estimate, which turned out to be highly competitive and the job was done quickly and with no disruption to anything on the property. A great choice for home services.

I had a previous electrician who never answeredd my calls for roof wires he installed. So. I looked up Electrical services on the internet and found Cornerstone Electrical. The receptionist at the office was very nice and sympathetic about my problem. She had sent Danial and his assistant a few hours later. They were prompt and very professional. He diagnosed my problem and the electrical box. Suggested I may need a new electrical box to replace the existing one. Previous electricians have said the same thing. The box is approximately 40 years old. I discussed with my husband and he also agreed to have this done. An appointment was made for 4 days later to replace the old box. So happy they will do the work. The price was reasonable and close to what my estimates were.Cant wait to check this off my to do list. Dan was very knowledgeable and fully explained the benefits of replacing the old box.4 days later, The new electrical box is installed and I am so happy. Dan and Rayna were outstanding with the installation and completed job within the time they quoted. I would highly recommend Cornerstone Services.

Paul Quinn installed an outlet in my fireplace to accommodate an electrical insert. He was on time, considerate of my home, and ensured I was comfortable with each step in the process before proceeding. It was a real pleasure doing business with him and with Cornerstone.

Paul and Brandon did an upgrade from an old service that was fuses to a 200 amp service and new circuit breaker panel. They ran some new wires and added a few new outlets. Both of these people were knowledgable and answered any question that I had for them without hesitation. They completed the job within the timeframe they quoted and cleaned up all their wires, etc. after they were done. They walked me through everything they did and explained all of it. Very pleased and giving them two thumbs up!!

David explained all services I needed to make my house warm up safely. Other companies wanted me to buy new boiler and David saw the service of fixing my gages and emergency valves on my boiler and more. My house is warm thanks to David and his young protege Devin I believe his name is. Both pleasant and patient with my 100 questions. Thanks Cornerstone Services

Cornerstone Services LLC is great! I called a few places for duct cleaning and exhaust fan replacement, and they were terrific! They came in 1-2 days and assessed everything. They returned quickly and completed the duct cleaning efficiently and thoroughly. They evaluated the exhaust fan and determined that it needed to be replaced. The exhaust fan was ordered and arrived in 3-4 days, and they came the next day to install it. All the technicians -- Paul, Izzy, Tom, Brandon, and Ron -- were professional and explained things completely (and with pictures!). It was about 2-1/2 weeks from first contact to completion of the job; no other company could even come and look at the job for 4 weeks. Highly recommended!

Glen was quick thorough and very nice. He did an excellent job with an electrical issue I needed done same day. I would recommend him to my family and friends.

Review 15 (2024-08-07 - Rating: 5)
Tyler did a fantastic job explaining all of my options after my air conditioning suddenly stopped working. There are a lot of technical terms in the industry, but he simplified everything while showing me what was wrong. It never seemed like he was only there to sell me something. I was presented several options at various price points, and he didnt pressure me into choosing the most expensive one or making a quick decision like other contractors have done in the past.When you call a contractor, you want them to be straightforward about diagnosing the problem rather than trying to impress you with a bunch of confusing industry terms. Everything was explained in simple terms, the price was fair compared to other companies, and I never felt like I was being taken advantage of. Thats all you really want when something breaks at your house.Replacing your HVAC system is probably the biggest purchase youll make besides buying a house or car, but I am very confident I made the right decision thanks to Tylers in-depth breakdown. I guess theres a reason this company has an average of 4.8 stars for nearly 900 reviews. 10/10 recommend.

So far so good! Theyve been working here for 3 days and everything has been great. (Progress pic attached) Jeremy & Paul have been professional, easy to work with, had great communication and most of all, the job is done right. They cleanup after they open up walls and other than the work thats completed, I couldnt even tell a contractor was here! Id 10/10 work with them again for personal projects and with all the other properties were working on. Finally, a contractor that is reliable, honest and doesnt cut corners! How business should be done ✔️ Thank you Cornerstone & John for being a pleasure to work with!

Professional, knowledgeable, thorough, personable, and efficient. I will definitely call Cornerstone again. So glad I found this company. I feel much safer now that my fire alarms and Carbon-monoxide detectors were installed. They even checked the electric panel. :)

He arrived , troubleshoot the issue and had us back up and running in no time. Thank you Cornerstone !!!!

Paul did all he could which is great but the company charged me 299 to send him out as an emergency then 395 for him to trouble shoot so the company made $694 to let me no they couldnt fix it. I am in the wrong business they made $694 in less than 20 minuts

I called today for an electrical problem and they had scheduled me for an appointment tomorrow which was awesome. A little while later I get a phone call and they had finished a job early and were able to come right now and since I work from home it was perfect timing. Tom showed up within 12 minutes and was able to fix the problem in about 15 minutes by replacing a faulty GFI all while training a new person who was learning. I always use Cornerstone and can’t say enough nice things about the people that work for them as every single person has been a delight.

My wife & I were exceptionally happy with electricians Tom & Reyna from Cornerstone. Weve used them for a number of jobs already & have them booked for a number more. We request them specifically for just how professional, quick & neat they are.First thing they always do is go over everything to make sure we understand completely what materials may be needed, how long the job may take, any & all possible outcomes we may or not run into, etc. And my wifes favorite thing is their never too busy to answer any & all questions we may have before, during, or after the job.Their workmanship is ALWAYS 100% spot on, plus their neat & professional, before, during & after the jobs complete.My wife & I could not be happier, (or luckier) finding Cornerstone & having Tom & Reyna as our electricians.Weve had so called professionals in the past do work for us, & not only did we waste a lot money, but we were just about always left with a meh, its alright, or a Its good enough, I guess finished product.Once youve had actual professionals like Tom & Reyna doing the work though, thats when you really see that vision in your head come to fruition!When it comes to home repairs, especially in this economy, I would, & have, recommend them to anyone looking to get their moneys worth, & also be extremely satisfied with the project outcome they paid for!

I wanted to take a moment to express my sincere appreciation for the exceptional inspection service provided by Glenn.As a recent homebuyer, I was understandably nervous about the inspection process, but Glenns professionalism, thoroughness, and attention to detail immediately put me at ease. He meticulously examined every aspect of the property, leaving no stone unturned in his quest to ensure my peace of mind.Glenns wealth of knowledge and expertise was evident throughout the inspection. He patiently answered all my questions and took the time to explain his findings in a clear and understandable manner. His insights were invaluable, providing me with a comprehensive understanding of the condition of my new home.Beyond his technical proficiency, Glenns friendly demeanor and approachable nature made the entire experience enjoyable. He not only performed his job with excellence but also went above and beyond to ensure I felt confident and informed every step of the way.In short, Glenns outstanding service exceeded my expectations in every way, and I would wholeheartedly recommend him to anyone in need of electrical work. His commitment to excellence and dedication to client satisfaction truly set him apart.Thank you, Glenn, for your exceptional work and for making the home inspection process a positive and rewarding experience.

Great job! My schedule was tough since I work during the week, but they helped to make it work. Everyone was courteous and professional.

What an amazing experience I just had with Dave from Cornerstone Services. I was in my basement at my home and smelt gas and I called Cornerstone Services right away. I dealt with Beth on the phone who was kind, understanding, respectful, and so nice. She sent Dave out to help me out during this stressful time and Dave was here within 30 minutes, amazing! When Dave arrived he was super professional, knowledgeable and was able to fix my water heater gas leak right away. Thank you to Cornerstone Services for a great experience during this stressful time. Will be using them for all my future projects and service calls!

Tommy came out to our house for an emergency electrical issue and diagnosed and fixed the problem promptly. He was very professional, friendly and knowledgeable. Having the membership with cornerstone is worth it for the peace of mind that comes with knowing they will get someone out to you the day of if you need it. (For an additional fee of course.)We used Cornerstone for a plumbing project also. Dave was extremely personable and did an excellent job. You can tell that he cares about his work.In addition to the other two jobs listed, I used Jason in electrical to install a ceiling fan and new outlets throughout. Extremely personable and professional! We had a nice chat about WWE.Jorge and Ashley from the Handyman portion of cornerstone came out to work on fixing a ceiling that had some water damage. They replaced the drywall and made a seamless transition to the existing ceiling and were able to match the texture perfectly! My toddler loved them both - big smiles whenever they walked through the door. Lots of positive energy.All of my experiences with cornerstone have been excellent. They are a family business that treat you better than family. I highly recommend them! Thank you!

Arnold and Shane were friendly, hard working, and did a wonderful job. They left our home looking beautiful and we will be happy to use this service again. Highly recommended!!I want to impress upon you all how pleased I am with the work that Alex, George, Ashlee, me Arnold, and Shane did on my basement restoration. They took a basement that had no flooring and holes left in the walls and ceilings from a previous plumbing job, and not only patched it all up, but made it look way better than it already was. This team works really well together, and goes above and beyond to do an amazing job I definitely recommend them.I am extremely happy with the handyman work we had completed by Shane and Alex. As always, they left us very satisfied and happy with the work they completed please use cornerstone for your handyman needs.Alex, Shane, and George, fixed two doors in our house that would not open or close very easily. They took a tiny bit trim off of them and now they open and close with ease and very happy. Thank you to the cornerstone team for doing an amazing job like they always do.Alex and Shane did an amazing job pressure washing and staining my front porch, leaving it looking new and revived. As I have stated in previous comments before, this is an amazing crew that goes above and beyond, and deserves all the recognition.Ashlee and Alex worked really hard on my back deck for the last two days. They pressure washed it and stained it, and the ending job was amazing. I am very impressed and happy with anything this team has ever done for us, and our home looks amazing due to them.

Impressed with the HVAC install/Service team. I had Cornerstone come out to clean my A/C ducts. They told me that whoever installed the system did not put the supply registers in correctly. I have 6 and 8 supply lines going into 4 registers because they didnt cut the registers down to match the inlet flex duct. My system was running at 50%. For the past couple years my system would run non stop and loud! On a 90 degree day it would struggle to keep the house at 75 and would take hours to go from 78 to 71. Now it drops in under an hour. Cornerstone cut down the cone on the back of the registers like they are supposed to be and now my system runs way more efficient and I dont have to turn the tv up when it kicks on!

Mitch came on very short notice ( next day) and looked at the water heater we just had installed less than two years ago from Denommee Plumbing. He was able to call the manufacturer of the water heater and send text pictures and got approval to replace parts (no cost for parts) and for $507.60 labor.When I called Denommee (Lowes suggested installers) they said I would have to pay full price for a reinstall ($2,740) and when they got approval from the mfg. they would refund me the cost of water heater $539. But the could be a processing fee. I would still have been out $2,201 for them to put a new fixture in.Moral of the story… this family will only use Cornerstone Plumbing, electrical, heating and cooling. They are honest and understand customer service. I will be contacting Lowes as well since the customer service person at Denommee said “we do this all the time, it’s legal and approved by Lowe’s. I’ll confirm that and if true, it’s Home Depot for us from now on!

Kevin came early. He called to say he had finished the previous job early and could come over if I was ready for him. I had to go to work but was able to let him in. He did a review and made recommendations about what needed to be done and the priority. He was able to get the work done promptly.Cornerstone is very good about making certain a customer is satisfied. Not only did the technician check with us, but before the end of the day, someone from the office had called to follow up as well. We have used the company multiple times and I am very satisfied vied with their work.

We just bought a home in NH. We were dreading having to go through lots of different individual service providers to see who was good and who wasnt. And then I found Cornerstone Services. I could go with one company with great customer service to handle all of my needs. It is a little bit extra, but its worth the premium, because you get hassle and warranties. I particularly appreciate Arnold for taking care of us and making sure everything got done on time.

George and Devon came out today to change out the trim on my full bath shower, unclog a sink, switch out a faucet, and trouble shoot a toilet tank issue. They were timely, professional, and helpful. The work got done quickly and efficiently - and they answered any questions I had. It was a very positive experience!

Cornerstone is a top notch company. I purchased a home that needed a full rewire and panel update. I reached out and had them send an electrician out for an estimate. With the scope of work that needed to be done I felt the price was fair. It may have been on the higher side, but for the piece of mind that there’s a whole company you’re working with, as well as the other services they provide by signing up for their yearly service, and mostly the quality of work, it’s well worth it. Brandon was the lead electrician for my job and was phenomenal. He’s a hard worker, professional, CLEAN, helpful, and most importantly he works with you if something small changes mid job. I changed my mind on where to locate certain switches and lights about 10 times and as long as he hadn’t started that portion of the job yet he had no issue updating his plans to make it work best for both of us. Brandon and the people he works with are awesome! Highly recommend them!

They explained all that they were doing and all my whys about things. They cared for the areas they were working in and throughly cleaned up their mess. The outdoor sensor light is great, light over kitchen sink is beautiful and safe now, kitchen ceiling fan/light is so nice and the replacement lights installed from improperly installed ceiling fans are also beautiful. Between what I and they picked out really added beauty, function and safety to my home. I appreciate the hard work that both Brandon and Jeremy did for me!! Keep up the great work guys!!

We had an odd electrical circuit issue and our prior electrician had retired. I found Cornerstone via recommendations from the local FB group and called them.Theyre customer service department works very efficiently. I had an appointment scheduled for the next week and they provided us with all the information about both the company and the appointment.John, the technician, showed up early in the scheduled window. He looked at the issue, wrote up an estimate on the spot, received my approval, and then identified and resolved the issue in a very timely manner.We also discussed future work at my request and I have quotes for that as well.This was a very good experience.

He and Tom were here most of the day replacing more than a dozen light fixtures including a huge pendant light that hung from a cathedral ceiling, a ceiling fan in the master bedroom and an outside light as well. Paul also replaced a couple of bathroom fans. I appreciate everything they both did and I won’t hesitate to reach out to Cornerstone Services again! I highly recommend them.

I had some boiler parts replaced. My technician was Jacob Estabrooks. He was also training Warren. Jacob did a fantastic job at educating me on what he was doing and what I should look for in the future ( this was extremely important to me). I also noticed Jacob educating his trainee, Warren. He seemed like a great trainer from what I observed. Warren was great as well, he seems like an employee I would want working for me. Both technicians are extremely educated and know what they are doing. I would trust them to work on my system in the future and will return to cornerstone because of their wonderful service.Hope this review helps others!

My entire experience with Cornerstone was fantastic from the very beginning. I contacted the company late at night, got a callback just after 9am the next morning in regards to power washing my house. I got an appointment for 2 days later (at my request) and John was very nice, professional and did such a fantastic job! He made certain my gates to the yard were closed so my dog didn’t escape too. I also called for an estimate for handyman work and the gentlemen came the same day and were also professional and very nice. Will definitely be using Cornerstone more.

I was made aware of Cornerstone Electric via a community Facebook page and am so grateful for the find and for this company! For starters, the administrative team is warm, communicative and diligent, and their professionals (read: experts in the field) are as quality as they come! We’ve been fortunate enough to have electrical services via master electrician Tom O. since day 1, who’s not only personable, knowledgeable and innovative, but utterly gifted in his trade, and has done nothing short of incredible work on our light fixture installations and repairs (in our 100 year old house with old electrical wiring, no less), antique light fixture rewiring, and on hiding TV cables behind walls, etc. He most recently supported a complicated rewiring of an old antique fixture - with a very unattractive chain and dangerous wiring situation - and went above and beyond to make a once heinous looking fixture into a beautiful statement piece in our entryway, braving a 14 foot ladder and a very narrow and steep space, and all without any complaints nor challenges that he couldn’t mastermind. His knowledge and skill in all things electrical is immense, and the fact that he takes pride in his work and cares about the quality of said work makes him the best electrician we’ve encountered, and we can’t recommend him enough. Brandon A. is another brilliant, patient and gifted electrician who’s incredibly talented as well, and although I can’t speak to all of the electricians at Cornerstone, if the rest are anything like Tom and Brandon then I can safely say that you’re in the best hands!We also utilized their HVAC services and Jacob and Warren were both honest, patient, highly knowledgeable and equally gifted as well! Jacob and Warren are both very clearly skilled in all things HVAC and - unlike other HVAC professionals from other companies that we’ve used in the past - seek to truly help their clients, caring about their safety, their wallets, and the quality of their air and heating and cooling systems. Jacob spent ample time explaining options to me and answered my barrage of questions without flinching and with professionalism and care, and the experience was night-and-day from that of our services with our last HVAC company.I really can’t recommend Cornerstone enough, and if you’re looking for quality work, reasonable prices and expert professionals, this is *the* place. 10/10 recommend and so happy to have found them!

My experience with Cornerstone was excellent from start to finish. We had called another electrician prior to calling Cornerstone and that person not only didnt show up but provided no explanation and we didnt hear from him again. Cornerstone, on the other hand, answered the phone, made the appointment and the technician showed up ON TIME. I got a text message saying when he was on his way. The person I spoke with on the phone for my estimate, Josh, was extremely helpful, friendly and professional. We had a bathroom fan and light installed, surge protection added to our panel and power installed in our shed. Jason was our assigned electrician. He arrived on time (and had the office get in touch with me when he was running behind), was respectful of our home and wore a mask the whole time, was kind to our three pets, and most importantly, did an excellent job. He even finished earlier than expected. We will absolutely use Cornerstone again in the future. Highly recommend to others.

I don’t post reviews often but try to for deserving efforts. First impressions matter. From the initial call where the service I needed was explained, a next day appointment was scheduled and an account was set up quickly to the work being completed on time and with quality - we had a really positive experience.Paul & Dalton were great. They arrived early after calling to confirm that was ok. They wore coverings on their boots, as well as face masks, at all times. They used drop cloths to protect the floors, stayed to do an extra job I had, cleaned up and finished before their estimated completion.Very professional and high quality service. You may find a lower price with another company but I don’t think you’ll find a better experience. Strongly recommended!

I reached out to Cornerstone for help with installing a breaker into my electrical panel as well as running a dedicated circuit. I spoke to Cindy in the office who helped to coordinate an emergency visit as I requested and these folks were amazing! They made arrangements to get an electrician out to my home immediately. (Im not kidding, he was here within 25 minutes... luckily he was working nearby!) My electrician was Rick, who was extremely friendly and professional and took GREAT care of my electrical requests -- I honestly could not have asked for a better technician! I later spoke with Beth in their office who helped me take care of all the final payments and she made sure that everything went smoothly for me during the entire visit and was genuine and caring about my experience. I highly recommend Cornerstone (and they service several New England states) so if you need someone... go here!

This was a home run for Cornerstone! Incredible service from start to finish! This was a complete Central AC install including installing all new ductwork. Andy & Britt were incredible. They were on time every day, and very personable. The job they did was great but I also appreciated how it looked. They took the time to tie up all the duct tubes so it was tidy and clean looking in the attic. This was a multi-day install, and there was constant communication on the schedule so I always knew when to expect them. The 2 electricians - Rick & Jeremy were the same. Very relatable and personable, on time and professional. They took care of the electrical install and also tidied up some other wiring. Front office was very professional and courteous, and consistently checking in on the job. Incredibly blown away by the amazing job the entire company did! I would recommend them 1000 times over! Great job to everyone!

Cornerstone Electrical Services is a terrific company. I am not from Haverhill and needed an electrician to look at a condo that we own there. I didnt know who to call. I found them on Google and I couldnt be happier with their service. Their office staff is wonderful and professional - they update and remind you about the appointment you schedule. I had a tiny job - an outlet needed to be repaired - I didnt think I could anyone to come for such a small job. Well, I was wrong. Stacey in their office scheduled the appointment and gave me a time frame. Unfortunately the electrician got held up for an emergency at the previous appointment and we had to reschedule. The appointment was reschedule today and because they had to cancel last week, they didnt charge me the service fee. Wow, how nice is that? Mark came and couldnt have been nicer or more professional. He diagnosed and fixed the problem and I couldnt be more grateful to him and his company for the amazing service. They are such nice people and wonderful to do business with.

Had home outlets inspected; 52 were found to be backstabbed and so were replaced with safer outlets and 3 were GFCI-upgraded. Also had 2 vanity lights replaced. Cornerstone is an outstanding company and Paul Quinn, who did all the work, was awesome and a very nice person to work with!

Paul was very professional, responsive, and hardworking. They were clean and left the place spotless. They were considerate and worked hard to get both jobs done in one day! It is so great to have bathroom exhaust fans in our old house!

I used Cornerstone to repair some outlets/lights that weren’t working and were behaving strangely. They also installed a new outlet and some new dimmer switches for me. They were super friendly, upfront on pricing and I didn’t feel like they were trying to tell me anything I didn’t need to do. Absolutely will use again for electrical work

During the last storm I had lost power on Dec 23, which was expected. What was not expected that I happened to check the sub panel to see if anything had tripped. Much to my chagrin, I found that many of the breakers were wet! I discovered that water was leaking from the power meter, through the conduits and into the panel! Not wanting power to come back on and causing a fire or some other disaster, I managed to reach Cornerstone and Paul was able to come over within a few hours which was great since it was just before Christmas and we were at the tail end of a huge storm. He checked over everything for damage and thankfully it looked like a recent issue as there was no corrosion. He then gave me my options to let things dry out and if nothing tipped (when power came back) I was good or if I wanted to replace the whole panel if breakers (especially the 200 amp main) kept tripping. I opted to go the path running the generator with the main off, popping out each breaker and drying them off and ended up replacing two GFCI breakers that were completely soaked but everything else has been good since. A huge thanks to Paul for coming on such short notice, well worth the emergency fee for piece of mind :)

Tom replaced 2 ceiling fans and 5 ceiling light fixtures. Top notch work. Very neat and communication was a real plus. Would highly recommend him.

Rick and Jeremy performed several jobs for us: rewire a bath/fan combo, reconfigure our bathroom switches, install a doorbell system, and upgrade our panel to include a whole-house surge protector. The price was SUPER reasonable, but that was the least of the good things. Rick and Jeremy were professional, cordial, extremely efficient, and super patient in answering all of my questions. The level of care and attention paid to the details of each of these jobs were impressive; you can tell that they love their profession. Im glad that they are there and will ask for them by name! See you next time!

Mike is a very pleasant and professional plumber who continues to go above and beyond to help solve our plumbing issues. We had an unusual and complex problem and he did not give up until we finally found the cause! Yahoo! They are in the process of fixing it now and I couldn’t be happier!

We were very happy with John Clarks electrical service. He explained upfront what he was going to do and what the cost would be, which was important. Very professional and we would use his services again.

From my initial call to service, stellar service and experience. In a day and age where professionalism lacks more often than not, I cannot say enough about Israel and the Cornerstone team. I’ve found my go to in the area and am very grateful.

There was a lot of electrical work to do at my house. Paul and Brandon worked hard in humid weather. With up to date lighting and GFCI plugs my house is far more desirable to potential buyers.

Brandon arrived on time, he quickly diagnosed the problem, discussed our options, and facilitated the repair. He was professional, courteous, and neat. I highly recommend the company, and will use them again. Gary

I needed an estimate for a electrical panel upgrade. Paul came and figured it all out which this cottage is a challenge, and gave me my options. He is very knowledgeable and trustworthy as are all the employees I’ve worked with. I highly recommend this company.

We werent happy about the bill for a fifteen-minute job! I know that I cant blame it on the technicians fault. They did do great work.

Review 179 (2020-03-30 - Rating: 5)
They came on time and did a great job in reviewing the issue and helping with ideas of how correct the situation. The issue was replacing a 50 year old kitchen through the wall Nutone exhaust fan. Paul did a great job with taking out the old and installing the new. He sealed it up and will review with his management team how to improve it being weather tight.

We had the boys from cornerstone electrical in our doctor office this past week and they were very professional and polite and even fun to talk to. A few of them were even saying hello to my patients and very careful not to be in the way, which I thought was very nice and over the top. there are quite a few bulbs in our office so I had them here for a few hours each day and was always greeted with a smile. Every one of them were aware of making sure they were not in the way of our business. Rick and Dalton (and the other three but I cant remember the names) were so kind and efficient and even grabbed my little sweeper and cleaned up the stuff that fell from the ceiling which was very much appreciated. I thought they were such professionals to every meaning of the word and even wished me happy thanksgiving before they left today. I enjoyed having them in my office this week and thank you for making my office bright and cheerful!
