    About 7-years ago, I had several large picture windows and patio doors replaced at a home on the beach. They all directly faced the ocean and take a beating from wind and salt. This installation was neat and tidy. The products had a lifetime warranty but like most consumers, I wondered what would actually happen if a window needed to be replaced. After-all, it was a harsh environment - and a warranty is only as good as the company making the promise.After 7-years of pounding from mother nature, one of the 2nd floor window's insulating seals let go and moisture developed. The business owner came out, took a look, ordered a new window and replaced it with no cost to me. Gracious and professional handling all around. I'm impressed.

    After calling Skip to relay that I was a bit anxious about the window replacement as I had been recently burned by another company with incorrect installation, Skip went above and beyond to ensure that I was completely at ease by providing great communication and photo evidence of the correct installation. My concerns were heard, extra attention/effort was provided and the overall service received was top notch. Highly recommended. 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!!

    I bought 7 windows from Window Source. There was a slight problem with one of the windows. Skip, the owner, was quick in responding and took care of the problem right away. I was very happy with the installer, Leroy, he was professional, polite and cleaned up. When he left, he took the old windows and storm windows and left me with new insulated windows.....no mess at all. I need a new front door and will certainly call Window Source. Thank you Skip, Leroy and Andrea.

    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.
