I got Heastings Electric's number from my Realtor. So I wanted to make sure I was getting a good deal, and made sure to get a few other estimates. Theirs was competitive, and most importantly they were able to come the next day to do the work.
I had several GFCI's installed (in front of the house and in the kitchen), as well as running permanent wiring for an electric garage door opener, and rectifying an improper electrical installation (by previous owner) of the washer/dryer. I also asked my wife to find out how much adding an outlet to the back deck would cost, as this wasn't on the original estimate (I hadn't noticed there wasn't an outlet out there until the day we moved in).
Not only did they arrive on time, and do all the quoted work quickly and efficiently, but when my wife asked them about the extra outlet, they said that since it was our first home, and they were already running wires near that area (for the washer/dryer) they'd throw it in for free!
I can't recommend them enough. As a new homeowner I consider finding a trustworthy contractor a rare thing. So I actually asked them for references for other contractors when the HVAC contractor didn't show up , and they were able to give me a great referral that showed up same-day and completed the work for half what the no-show contractor had quoted us.
