"Used this company previously and again it was a pleasure from beginning to end. I would give him 10 Stars if I could. Referred William to a close friend of mine and she was just as pleased. We both sleep better during our bad Florida thunderstorms. A friend of mine lost their home due to lightning. They got out just in time couldn’t save anything but their lives barely. I urge all to install lightning rods."

"The problem turned out to be a burned out small electric door switch. I believe the price was way too expensive for the service performed and the price of the door switch. What more can I say? It got done."

"I have been searching for electrician to come out and fix our voice, Network, and camera lines for our small business. I searched for weeks and wasn't so lucky. I came across homeadvisor.com and saw Progressive Consulting. I gave him a call, 10 minutes later her arrived at my business. I explained what I wanted and he already knew what it would take. He gave me a quote 30 minutes later. Very affordable price for the work he provides. The next day at 9:30 am he came out and completed the job just as estimated nothing less nothing more. I would HIGHLY recommend this company to anyone looking for electrical work. Quality and affordable couldn't ask for anything else."
