Had a new boiler installed on Dec 24 for 20k...ouch. the tech was great but they kept hounding me…read moreto leave an extended review, I didn't. Aug 1 2025 had to have boiler serviced as it wouldn't make hot water unless furnace was running. Same good tech came out and discovered the issue was a small aquastat (?) Device that wasn't replaced along with the new boiler; ok that makes sense. The small meager uncomplicated part cost me 676 bucks for a part no bigger than a cell phone. Again I gave the tech 5 stars but again they called and began trying to get a better "customer review". Told them the cost was insane and it seems like a case of fraud as I never got a detailed receipt outlining the parts etc. I'm thinking of collecting info and retaining a lawyer to get to the bottom of this. The tech was a decent knowledgeable friendly guy, to bad cornerstone isn't. No wonder they get 3 stars on yelp.​​

He answered the phone immediately, communicated easily through text after I sent him some photos of what we needed to be replaced, and gave us a clear fair price of what it would cost. On the day of he was on time (even on a Saturday), professional, friendly and knew what to do, even walked me through what he saw and taught me how to maintain it. I bought a lamp that didn't perfectly fit, but he helped cut and drill to ensure that it did and did a great job. I will definitely be using his services in the future.

I looked on the web for local electricians with good reviews and found Steve. I set up an appointment and Steve was right there. He talked through the work with me and all the what if scenarios for the job. I received a quote very shortly after. We scheduled a date and Steve came and did the work. Is he the most inexpensive? No, but you pay for what you get. And in this case, I got exactly what I paid for - good service, the job done well, and a very organized transaction. Not to mention, Steve is very personable, which makes it easier. I have to say that, in all my time, I have never seen a contractor who is so organized in my life. I am a big believer in doing what you say will do and Steve lives by that. I will definitely use him again.

He came on time (even a little early, after asking via text, what a gem) and was able to troubleshoot and complete the repair within the hour.

So glad to have found an electrician we can trust.
