Very pleased with The Window Source. Quality product and installation with customer satisfaction a top priority!
Friendly, professional, worked fast and cleaned up when they were done, and the best price we found.
Fantastic Company!! The installer that installed my windows was the hardest working person I have seen in many years. He worked straight thru until everything was done. My neighbors saw the work that was done on the outside and inside and could not get over what a great job!! I am extremely happy with my new windows, prompt, courteous and excellent service. Planning on getting some more windows done by the same Company.
We are very happy with our new windows from the Window Source NH. The installation was quick and the installer was very professional and polite. The price was reasonable too.
We are very pleased with the work done by Craig at Window Source. He worked without pause and cleaned up as he went along. Next time we need windows, we will call Window Source. AJM, Newburyport
