Inna Bullock
We had Kamoska widen an exterior door frame on a very old house (always so many surprises) and install the door and a second story window. They were super professional & did very high quality work. The team was a pleasure to work with, I would highly recommend them for any similar work
Leah Scott
Thanks guys! Wow quality for a reasonable price. I changed a wooden window, got a quote from three companies, Victor's price was one of the most reasonable. And I was surprised by the quality of the work. The guys coped with their work quickly without loss of quality.
