I had an electrical problem and needed someone out asap. Jerry G came out and found the problem. He was wonderful and made a tough situation very tolerable . I have been a customer for years and recommend them highly.

We previously used Cornerstone for a plumbing issue so when we had a major problem late Saturday afternoon, we called them again. We found a drip in our garage ceiling and when we pushed on the ceiling...water poured out! We concluded it was coming from the second floor a/c. Called them and Tim, our technician, came out to inspect. He was very knowledgeable and super nice. He wanted us to understand the system we had and he reviewed it with us. He found the problem and had it fixed in a couple hours. He kept us informed throughout the entire job and answered all of our questions. We signed up for their monthly program and will be calling to schedule our plumbing inspection soon. We are very happy with the service we received and would recommend highly! I will update review after our plumbing inspection. I am hoping we get another amazing tech! Five star review!!

My expensive of a plumber charging a consultant fee, usually has been VERY expensive. A plumber should know how much it would cost to change out a toilet, even with additions parts needed.

These people are such pros that they charged me $750 last October to fix my system and promptly wired both the outside fan and compressor backwards. When the outside temperature finally got hot enough for an extended period of time, it finally stopped working on April 29. They wanted to charge me a trip charge to come check it out which I am glad I refused to pay since I have serious doubts they would have admitted their error and like found other issues for which they could charge me. After reaching their escalation department I was told that since I had another AC guy come out instead of giving them a chance to check it out, they would not reimburse me for his fee to fix THEIR ERROR. They claim to have pictures of their work from October, however refuse to share them with me or admit the error. I am done with them and strongly advise you to find another service provider.

Highly recommend Jerry. I have called on expert electrician Jerry twice now, as he does excellent work! He goes above and beyond. Also, just a nice guy. Put in an outlet for us and repaired my hall light on his first visit. Second visit he replaced all my outside lights. He cleaned up all the old caulk and replaced the fixtures lighting up my driveway. He also replaced my back patio floodlights with cool LEDs. If you want a guy who knows what he is doing ask for Jerry.

I used this company for an electrical issue I had. Manny arrived on time, he took all covid precautions & followed CDC guidelines. He explained to me everything he was doing. I was very impressed. Knowledgeable and friendly. A++ would recommend and will use again if ever needed.

Highly recommend! This is the second time that I have contacted your company for help and again you don't disappoint. I was impressed by Tim's professionalism and the way he took his time to explain things to me. So much appreciated. Thank you again

We had a flood in our Condo which flooded our electric panel. The power had to be turned off until we got a licensed Electrician out to make sure it was safe to turn back on. As we all know, water and electricity are not a good combination. We found Cornerstone on YELP. Since it was a Holiday weekend, we were forwarded to an after hours message center to schedule the service call. They were prompt and efficient. On the day of the call, we received periodic updates on the technicians location for his ETA. Chris was very professional and was able to service our panel and check out our mechanicals. Pretty affordable call.

They are still trying to get it right, but they are making progress. I had a 12-year old AC system. I had ZERO problems. Plenty of cold air, acceptable humidity with 1 dehumidifier that I emptied once a day. The unit cycled on and off as anyone would expect. I decided to replace that system with new so I could control when and for how long I'd be without AC. I was sold a state-of-the-art AC system that was allegedly much more efficient and would lower my electric bill. A Daikin DZ18VC0361 with a DV37PECC14 Air Handler. It's an 18 SEER 3 ton unit and I have a 1,500 SqFt home. What I have is grossly less efficient and my electric bill is 10% higher. They arrived at 9:30am, left at 11:30pm. The next day the AC ran all day long. They returned and saw that they had forgotten to connect some ductwork. A couple days later the AC was still running all day. I was now using 2 dehumidifiers that I emptied twice a day. They returned and discovered another section of ductwork had been torn open and needed to be replaced. I had to pay for that and they replaced it. A couple of days later the AC was still running all day and couldn't catch up until late evening. They returned and checked all the ductwork and sealed all the ductwork. They corrected some things found by the inspector. The inspector returned and said the Air Handler was leaking cold air into the attic. They allegedly fixed that, checked everything. The AC still runs all day, can't catch up until early evening. In order to maintain 79* the unit has to be set at 74*. I was able to maintain 45% humidity using 1 dehumidifier that I emptied once a day. Currently I am am unable to maintain 45% humidity using 2 dehumidifiers that I empty twice a day. The inspector returned, along with the new installation manager for Cornerstone Pros. The air leak had apparently been fixed. However, the inspector found another problem. Three weeks later and haven't heard a word. To be continued.

I was in panic mode when I noticed a wet spot on my ceiling! After narrowing down the issue we contacted Cornerstone Pros. The very next day (it was late when I called) Quenton came out and after climbing around in the attic he figured out what the problem was. Quenton was very professional and very helpful. He turned a very stressful situation into a very positive experience. Thank you Quenton and Cornerstone Pros for taking care of us with the best customer service experience I have had in years!
