David was recommended to me by Friendly Plumber. Wow, what an excellent find! He fixed all the light switches in the house that don't seem to correspond to anything in particular and he was really nice about it too. The price I thought was fair. I highly recommend him!

Okay, maybe just a tenth of a star reduction for some very minor lingual mishaps. But these guys are just as good as the reviews stated and I couldn't have been more pleased with their ability to work within our budgetary constraints and the idiosyncrasies of our home. We'd just gotten a secondhand hot tub spa situated in our back yard and wanted the electrical hookup installed before my birthday weekend without breaking the bank.
Their schedule was full but if we could manage a minor task in advance of their arrival, they'd have us up and running by doing a couple of hours after dinner. God bless 'em! I spent my birthday in warm, jet-swirled waters. And I certainly won't have to spend an hour researching who my next electrical contractor will be when I need someone; David and Helen are our new go-to guys!
