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!

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.

Very pleased with Cornerstone Electrical Services! They were very prompt in responding to my request for a quote. They responded, called and demonstrated excellent customer service! They were able to show up at my home promptly and checked the work out needed to be done and were much more reasonably priced both for the quote and for the actual installation. Then as a thank you, I received a $25 dollar off coupon in the mail for future work, which I do have coming! In February, I will be receiving a new light fixture that needs to be hung in my foyer to replace the one that is currently there. You can be sure that I will contact Cornerstone immediately upon receiving the new fixture and will have them do the work. Do not hesitate to contact them for any electrical work that you need!! Happy Holidays to all!

Had a ceiling fan that stopped working, had couple of parts the company sent me to fix it. The rep was friendly and professional, installed the parts and had the fan working in about half an hour, seems fine. Price was very reasonable after $50 first time customer discount was applied. The only reason I didn't give 5 stars is because the time range given to me was between 11 AM-2 PM. I got a call at 8:30 AM saying he was near the area, arrived at 9:15 AM.

We called this company to fix a wall outlet for our clothes dryer. $47 to just show up, $137 to do the job of REPLACING A FUSE! Home contractors are a bona fide RIPOFF! Their tech Bob was great, but they could've waived the $47 :( Ironically, the company owner is a Pastor part time...

We bought a home which had sloppy electrical work. Many uncovered cables, etc. Cornerstone electricians were professional, used modern communication for quotes & invoices. The team clean and very polite. Prices are fair. We will definitely use them again for additional work.
