Electric Service Installations

I had a situation that was an inconvenience more than an emergency as I lost powered to my garage that is in the back of my property. I called on a Tuesday afternoon and they responded immediately and said they would be out at 7:00 AM the next morning. They spent all morning trouble shooting in the garage trying to find why my breaker kept tripping for the garage. After doing some minor repairs and the problem still there, it was determined that the issue was underground going from the house to the garage. The issue being there was still about 6 inches of snow on the ground. With a little bit of a warm up over the weekend, they came out and started digging a new trench, even though the upper part of the yard was still frozen. They started early in the morning and worked like bulls to dig the trench, lay new wire in conduit, and did not leave until the garage was back in operation and all the dirt and grass was put back in place. I really thought I would need to wait weeks to get this work done but they said they would complete as soon as possible and they did. I could not be more pleased with the service they provided.

This company exceeded my expectations! Im more of a do it yourself guy and ran into major problems on a rental property... I had a cornerstone card in my wallet for a while so reluctantly I called JT..Best move I made! Fixed all of my electrical issues and even had him do some framing for me, you cannot go wrong Using Cornerstone!

I have rental properties and I’ve used Cornerstone Construction on multiple occasions to do electrical work and rehab jobs and the work, communications, and timelines were always prompt and great quality.

Cornerstone Construction did an amazing job for us. Their electrician was on time, professional, and really knew what he was doing. Everything was explained clearly before the work started, and they made sure the job was done safely and the right way. The quality of their work stands out and you can tell they take pride in what they do. Pricing was fair, communication was great, and they left the area clean when they were finished. I highly recommend Cornerstone Construction for anyone who needs reliable electrical work.

I recently worked with Cornerstone Construction , and I couldn’t be happier with the results. Their team does excellent work across the board, but their electrical skills truly stand out. Every part of the project was handled with professionalism, attention to detail, and clear communication. They showed up on time, completed the work when promised, and made sure everything was done the right way. From electrical upgrades to interior renovations, the quality of their workmanship was obvious. It’s hard to find a company that is reliable, knowledgeable, and takes pride in their work—and they absolutely do. I highly recommend Cornerstone Construction to anyone looking for electrical services or complete home remodeling. They exceeded expectations in every way.

Very happy with the work done to my home. They came and gave an estimate that was on point. Work was done in a reasonable timeframe. Highly recommend Cornerstone Construction!

JT and his company Cornerstone Construction did an amazing job with our electrical system in the house, I would truly recommend them for anyone who needs Construction services of any kind. Truly a lifesaver. G. Covell Tamaqua PA.

Answered call right away. Came same day and fixed the problem. Very professional. Price was reasonable. Everything looks and works great.

We had Cornerstone repair and remodel our sunroom which had serious damage due to moisture and poor construction. There was structural damage that threatened to destroy the room. Ed and John are master carpenters and made recommendations that made the structure sturdy and safe. Without them identifying these problems and making the improvements the room would have been unsafe to continue using. They did an excellent job. We will definitely use Cornerstone for future work. Their prices are reasonable which was great because we are retired and on a fixed budget.
