"I had three light fixtures to install in place of three older lights. These fixtures were in the Dining Room, and two bath rooms. While seemingly an easy effort, as always, the new installation was complicated in two of the three installs. With Marty's expertise, all issues were quickly resolved. I will use Marty's services (Silk City Electric) again"

"Anyone looking for quality electricians, do not hesitate to contact Epic Solar & Electric! Just had them replace and upgrade our old Federal Pacific panel, run a sub panel to the garage, and bring everything up to current code. They were on budget, on time, and great to work with. Highly recommended!"

"ELI was wonderful! He arrived on time, was friendly, thorough and quick. What really impressed me was ELI'S attention to the little details--he made sure no water, garbage got loose under the counter, used a mat to protect my floor/inside counter, cleaned up everything--even my sink--when he was done and, finally, put everything back under the counter where it was before he came! Above and beyond customer service! I will recommend AAA who anyone who needs drains unplugged! Also I like the company and especially the SERVICE so much, I'm meeting with a tech for another job--electrical this time. THANK YOU, ELI for your time, service and patience with my speech! much appreciated!"
