"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."
