Denver Basement Remodel
“I hired GTC Electrical to help with a basement remodel at my home in Denver. They were so easy to work with and upgraded all of my old electrical switches and wiring to new, up to code switches, outlets and dimmers! They even helped me add wiring for new halo lighting. I couldn’t have done it with out them. They were very easy to work with and affordable. I would definitely use their services again!”

Commercial Repairs & Upgrades
“We have worked with GTC Electrical for a few months now. We have a large commercial space that needed a lot of electrical work. They have been such a great electrical contractor to work with. Gary has helped us finish much needed electrical panel upgrades and run new conduit and wiring in stages, that allows our business to operate with little to no downtime. We are so happy we found GTC, they are definitely the guys to call if you need big commercial electrical upgrades or repairs.”
