I’m a hardworking person who doesn’t like to leave projects half finished or looking sloppy, I can be a bit of a perfectionist. I’ve always fixed and built almost everything I needed myself and I take pride in being self sufficient. I’ve been an electrician for a year and half now and before that I was fabricating aerators for private residences. I have a wife and two children, so I can handle the chaos of a whole house remodel even if you decide to alter any details halfway through.

"Got my ductwork cleaned out and replace 23 outlet covers. All done in record time. Very friendly and professional and explained the whole process as he went and showed me all the junk that came out of my ducts. Cleaned up as he went along and couldn't even tell he had been here except that there's no dust floating around in the air now."
