 Trustindex verifies that the original source of the review is Google. We had a good experience with Window Seal West.  Everything was professional.  They adhered to the quotation, were punctual, and installation proceeded without issue.  The quality was outstanding and we immediately noticed a difference in our rooms; they were warmer and quieter.  We still want to change the windows in two of our bedrooms and will be contacting Window Seal West again.

 Trustindex verifies that the original source of the review is Google. I recently had a front door built and installed by Window Seal West. It was a great experience from start to finish. Anthony was very knowledgeable and they allowed us to visit their factory to see the quality of their product. We had several quotes before them and they were by far the best of the companies we interviewed. Their work was timely and very professional with great finishing work and clean up. The workers were very respectful and pleasant. We need some new windows in the near future and will  definately use them.
