I got a shingle roof replaced here recently by them and it went perfectly! The crew cleaned up well and with my neighbors being so close I was worried by the debris getting in their yards but that did not happen. They cleaned up so well and did such a great job that actually one of my neighbors got one of their roofs done as well by them. Highly recommend working with Harkness and Gamm Construction!

I have been using Sam and Evan for years and have always had a great experience! They assisted with a full roof/shingle replacement due to storm damage at my mom's house, as well as replacement of my roof several years later! They were my go to in helping replace my shingles here and there on my roof until it was time for a replacement. I recently bought a new house, and they were my go to to look over the roof on my new house as well. If I have any issues here/when I need a new roof they will be who I goto as well! Don't hesitate with these guys they will take care of you!

Harkness & Gamm made repairs to the exterior of our home. They came out to take a look at the house, provided us with a written estimate and proof of insurance. They did a wonderful job on the repairs and their communication with us was great. You don’t always find that with companies. Would definitely use them again.
