As a general contractor with over 20 years in business, I was not impressed with their work. They ripped out whatever was in their way and left a mess that had to be fixed/covered up. In one instance, they only needed a couple inches and they could have installed the duct behind a closet wall/bi-fold door but instead they busted up the trim and tore out framing to do their install directly in the way of the door. I understand that the owner who was selling the house probably didn't care - they likely just wanted the "cheapest" thing done to get the sale, but it showed a distinct lack of foresight AND a lack of respect for the new owners (my sister, brother-in-law and their kids). It really isn't THAT much more difficult to CARE about one's work! Based on that, I cannot recommend them.

They came when my parents were there and left without a comment and so I assumed it was fixed. After a week it came back on again and I had to follow up with Wilkes where they said they had to come back out since they couldn't get to it directly and had to go through the basement ceiling. They came back out again, charged me more money for the 2nd trip, and said it was fixed. Side note, they had to call a third party Jacuzzi service for advice on how to fix it. A few months later the same problem started again and I called them to see if they would come out and fix it but to my surprise said that because it has been over 60 days, that I'd have to either make another claim with the home warranty service or hire them direct at $60 per trip + $110 per hour. They do not do a quality job to start or on the 2nd time around nor do they warranty their work more than 60 days so I would definitely not recommend this company.
