Cornerstone Pros

Have used Cornerstone for our AC needs for years and have always trusted them and their team. Recently we started using them for electrical and plumbing and were happy with them in those areas, too. We signed up for their """"maintenance plan""""... not sure what they call it... and all 3 technicians showed up on the same day as promised to do their inspections. They uncovered some potential problems throughout our property BEFORE they became BIG problems. Being a member of their plan saved me a fair amount on their posted rates. That said, the only feedback I would have for them is to quit advertising so much and driving their rates up. Their prices are still reasonable... but are on the high side of the other quotes I received. In years past, they would always have been a five star, but I was able to get the work done for less elsewhere. As for the quality of their work and the cleanliness and professionalism of their staff... you won't find any better, anywhere else. FIRST CLASS OPERATION!

After our AC stopped working we researched companies and read reviews from Yelp. Cornerstone had received good reviews so we decided to give them a try. We were very pleased with the results!! We called this morning and received an arrival timeframe of between 10-2. We also got an hour call ahead to let us know they were on their way. Our technician, Richie, was very professional and had our problem fixed by 12:00 that afternoon. We will definitely be using Cornerstone again!!

In all of my years on this planet dealing with contractor after contractor this is absolutely the worst contractor I've ever dealt with in all of my time. Can I simplify or understate how horrible this contractor is? They kicked my ceiling in and did not repair it. On two separate instances they tried to burn down my house and my whole wall turn black. Brand new installation has only worked at most two months at a time and I'm over a year in and out of warranty now. Under no circumstances would I ever call this contractor they are the worst I've ever dealt with

I have nothing but exceptional things to say about Cornerstone Pros. Their customer service was second to none. They were able to diagnose and replace my faulty hot water heater within 24 hours and it was over the weekend! Kiel the technician was professional and polite, and his work was extremely clean. Kiel even gave me a follow up call later in the day after the install to ensure everything was working properly. This type of service is rare in this day and age. That goes for Kiel and everyone at Cornerstone Pros that I spoke with. Extremely satisfied customer!!

Super responsive customer service. Pete was a big help with some older electrical equipment - knowledgeable and ingenious.

Purchased the $49 Angie's List Deal for A/C Maintenance, Cleaning, and Tune-Up, including a Duct Fogging sanitation with One Pound of refrigerant. They reasonably charged an additional $29.95 for second A/C unit. Super communication with company. Answered each email promptly. A technician named Matt arrived and immediately put booties on his shoes to protect my floors. He introduced himself and explained everything he was going to do in great detail. He was meticulous and thorough....he took his time -- was not rushed. I was super impressed with the overall experience with this company from beginning to end. If you are a Angie's List member check out their specials. They also offer competitively priced warranty packages.

Nice work replacing a leaking coil in our air handler; efficient and very effective. Top notch professional job performed by Scott and a day or so earlier Matt. Cornerstone is a great company to do business with in my opinion.

Been There Done That I.

I'm in the process of buying a home and just had a home inspection performed. The inspector pointed out a couple of issues that should be repaired by professionals. The exposed copper wiring in the electrical panel had blue and purple discoloration, and using an infrared camera, he detected moisture buildup in the wall between the master bath tub and kitchen. I reached out to Cornerstone for a couple of repair quotes, since they had good reviews and their site advertises that quotes are free, so I could try to negotiate the sale price on the home. After submitting the details on their website, I was called less than 15 minutes later to be informed that technicians would have to go onsite to inspect before giving me quotes for my requests, but that they would give me the reduced rate of $39 for each, rather than full price. Not quite free as advertised, but I agreed on that price thinking it was gonna save me some money on the house. After scheduling the appointments for 2 technicians, I wasn't able to get my schedule cleared to be onsite while they were there. Cornerstone told me I could provide them my CC to have on file, and as long as someone was present to let the technicians in, they could perform what was agreed to, call me to let me know what was recommended, and if their was anything to be done immediately, get my authorization to do so. I let them know the current home owner's renters would be present to let the technicians in, so all was set. The electrician calls me and says he doesn't see any discoloration in the electrical panel wiring. I saw it for myself, and had the pictures in my inspection report.I told him my worry was about a possible fire hazard, because that's what the inspector told me to be wary of. He said there weren't any problems, so I thanked him and that was that. I never spoke with the plumber. He left me a voicemail stating he couldn't find the leak. Well of course not, it's behind the wall. And I didn't need it to be found yet, just a quote on what it could cost to find it and fix it, given the different things that could be causing it. I called him back, and left a message saying as much, but he never called me back. So I've effectively paid $80 and have no quotes to show for it. I emailed Cornerstone, because I felt what I submitted on their web form, wasn't properly communicated to the technicians, especially the plumber, and I wasn't getting what I asked for, which should have been free in the first place. I provided the pictures from the inspection report to try to be as clear as possible. The following morning, I received 2 voice mails, one person asking for a call back, the other saying they would send another plumber back to the property. I call back, and neither person is available, so I explain to the new person on the phone, I don't need service performed, I need a potential repair quote to negotiate the sale price of the house. After being put on hold for a few minutes, I was finally given some $$$ figures to go along with several different scenarios, which is all I wanted in the first place. They typed it up and emailed it to me to provide to my agent. But my experience gets worse from there. I had 2 charges show up on my credit card, as expected. One was for the agreed $39, the other was for $213!! I call Cornerstone back and ask for an explanation, since I was told $39 for each one. They tell me the plumber performed a visual inspection and this is how much it costs. Again, I was told $39 which is all I agreed to. Anything more than that, they were supposed to call me for authorization. They said they didn't know who authorized the extra charge, which made me irate because why would you accept an authorization and not know who gave it, especialy when it's not the person paying for it! They asked if I would like someone from management call me to discuss further, because they couldn't do anything about the charge at this point. Damn right I did! They were supposed to have a manager call me within 24 hours. 2 full business days have come and gone, no call. Seems pretty clear to me this company uses false advertising, poor communication and plain dishonesty, to try and get money out of people.

So my toilets been dripping for about two months now, and now it hasn't fully flushed in 2 days. I decided to give this company out since there has been such positive reviews about them. I'm really glad I choose them. I didn't have enough time to call about the service so I filled out a form online. I probably for a call roughly 2 hours later. The lady on the phone was very nice and accommodating and we set up a time for the plumber to meet. He was right on time the next day. Well, actually 10 minutes earlier then expected. His name was Michael and he was very sweet. He answered all my questions, gave me a few recommendations and went right to work. He was spot on about what the issue was was my toilet. I'd definitely recommend them!

Very disappointing. I had called to schedule a service as my sink was clogged up. I was told I would have someone out to my house the next day in the afternoon. Well, that comes and goes. I call around 7:30pm to see where my tech is and they said I was next in line. I call again around 9:40pm and got the same thing """" you're are next in line and they will be there by the end of today"""". Well needless to say I never received any phone call , no updates or anything for this appointment. I ended up calling this morning and the receptions couldn't give me any reason as to why this happened. That she can see I was scheduled for yesterday. I canceled my appointment and I went with Roto-Rooster. They came the same day and fixed my plumbing issue.
