"We were VERY PLEASED we hired TAMCOAT! WOW, they did an AWESOME job and we now know to call "OUR ELECTRICIAN" for any future jobs. We gave them about 6 - 7 "TO DO" items and the work was done very efficiently and quality all the way. We were VERY IMPRESSED! Thank you TAMCOAT for your fine service."

"It went very well. Due to some problems with kitchen appliances not working properly due to bad circuit breakers and knowing the electrical panel is about 30 years old, I thought it was time for the panel to be replaced and possibly upgraded.
Matt checked the panel, determined a complete panel replacement was not needed, only replacing all circuit breakers. Some of the installed breakers were failing.
The work was done quickly and professionally. Matt spent time as he worked telling me what he was doing and answered my many questions.
I especially appreciated his evaluation of our electrical power needs. Based on our electric power usage now and in the future, he said we did not need to increase the amperage of the panel.
Since the work was done, all kitchen appliances are now working properly.
