Hear From Our Happy Customers

KTM exteriors repaired and renovated extensive rot on the front of our lake house over the fall. We could not be happier with the outcome or with the process. We were kept informed of the progress with texts as well as pictures, and any change orders were fully explained. The job supervisor, Steven, was informative, pleasant, and kept us up-to-date, which was hugely important to us. The outcome was better than we could’ve expected. I highly recommend KTM.

Linda Weatherbee

They were unbelievable! Everything was on time, and they did an absolutely perfect job. Insanely professional, and worked SO hard! Our home looks brand new - see the photo! I had several companies come out for quotes, and KTMs Robin, was the only person that spotted a problem, and proposed a fix. It wasn’t a hidden problem either. He alone was amazing. I can’t recommend KTM highly enough! You won’t be sorry!

Charles Pouliot

Ktm was able to find the source of a ceiling leak which had been plaguing us for months despite the efforts of other contractors. Dealing with them could not have been easier, someone answers the phone and responds to questions quickly. Scheduling was easy and the workmen arrived on time and were professional efficient and did top notch work... I don't think you could go wrong with KTM.

Robert Fortunato
