The Window Source NH

I am very pleased with the looks, quality and the quietness of the windows and sliding door. It looks so much brighter. Your employees did a great job and were very personable and professional. Thank you!

The Window Source of southern NH installed new casement windows in an addition on our existing home. Communication and scheduling was excellent, installer Craig is very professional. Windows look great and match the existing house which is 40 years old. Told the owner, Skip we will be calling him again to replace a couple old windows. A+ company and customer satisfaction!!

We reached out to the window source to install 9 new windows in our 1900 year old house. Gary who came out to give us a quote was easy to work with and very informative. He walked me through what the process would be and why we needed what we needed. We had two other companies give us quotes but we felt the quality and knowledge of the window source company was the best option for us. For installation it was such an easy process and the installers were very professional. They completed the project in two days and it looks amazing. They really did a great job and I’m very happy we decided to choose the window source.

I love my new windows. Everyone I dealt with from sales to installation was very nice. Installers were very neat, cleaned up after themselves and did a fantastic job. My husband was impressed with how hard they worked. I would highly recommend this company.
