Best to get an estimate from other plumbers. I think I made the mistake of paying top dollar for a water heater replacement $3,200. On top of that, they now hound me with all kinds of upsells - like memberships, etc.

John requested a phone number to contact me which I gave him and never heard back from him. Went with someone else.

Scheduled 2 weeks in advance Took day out of work, planned a simple electric box installation. They called me the day before and asked to change my appt to 'now'. I could not accommodate and asked to keep my same appointment. I was told fine and 2 hrs later they called to cancel and reschedule. I had contractors coming in and working around this appointment. Horrible service, no explanation or understanding of the situation. Would not recommend or use this company for anything.

Less than a year ago, they put a water heater in my townhouse. my mother owns the property so she gave the go ahead on the replacement. Unfortunately she didn't check with me first. We were in Florida on vacation at the time. They charged my mother 3 times what it should've cost. I swore I'd never use them again. Then the water heater started leaking so I had to call them because they put it in. They told me it was not leaking. When they came, I had been having problems with the hot water in my shower not getting as hot as it used to. I mentioned it to the guy who came. He told me we needed to replace our pipes and quoted me $6000-10,000. I was shocked he would say that. I knew that's not what it was since I had researched it. It was the mixing valve. After he left, I had absolutely zero hot water. I called another plumbing who fixed it for under $500. The water heater that ""doesn't leak"" has water pouring out of the overflow pipe all the time. We obviously need to get that issue fixed since it's constantly pouring into our basement, even after we put a pan under the pipe. I do not want these people in my house ever again though so I will be looking for an honest plumber. It's sad to try to trick people into paying so much money for something not even needed. I am also disgusted about how they took advantage of my elderly mother!!!

I originally called this place to get a quote but ended up cancelling bc I chose to go with other companies to give me estimates bc they did not charge me a fee to get on site. A woman called me from Cornerstone and asked me why I cancelled and I told her I was going to work with other companies who did not charge a fee to give me a quote. She lied and said they have a promo going where they are not charging the fee. I made an appointment and they still charged me after telling me it would not be a cost. Bait and switch, and I do not plan on working with a company like that

We were looking to get our vents cleaned. One company came in and quoted us $1200. We thought it was a bit high so we called John. He came out in a timely manner and determined our vents were actually clean and didn't want to provide a service that was unnecessary just to make money. Shows you how professional this company is. Honest and knowledgeable in the field. We will be contacting Cornerstone in the future for any services we may require!

We had a plumbing issue, though not an emergency was still urgent. I called Cornerstone, and a plumber was here within a couple of hours. The cost of the work did not exceed the estimate. The plumber was cordial, professional and kept us informed on the work being done. I must say we have used Cornerstone before for electrical work. We highly recommend them.

Easy, fast estimate with same day completion! I needed a gfi outlet near my toilet after purchasing a bidet. I appreciate how Cornerstone sends a text to you letting you know the technician is on the way. Rick was not only very professional, but very personable as well! He was on time and completed the estimate/job same day at a very reasonable cost. My neighbors are always sharing 'vendor' info to help each other out, and Cornerstone is going on our list. Service matters to this company - you can tell by the reviews!

Renae M.

Way over priced, was charged about $600 to change out 6 outlets and 2 light switches. Would not use Cornerstone again.

Rick Gerbrands was simply excellent! He showed exceptional technical competence, as well as, solid customer relationship skills throughout the job. From the moment he arrived, he was focused on providing value and customer satisfaction. He not only fixed the laundry list of electrical issues, but he also took the time to explain what he was doing and why. This style gave me extreme confidence that his work would be done the right way, the first time. If Rick is an indication of technician caliber at Cornerstone, then I would not hesitate to recommend them to anyone.
