Good service. Had to wait for the windows to be custom made but that is to be expected. Installers were excellent and guarantee their workmanship.

Recently, we were faced with the unpleasant experience of having a leak in our home. I was introduced to Eastern Siding, Inc. and the crew went above and beyond to ensure our needs were met. The team members were incredibly professional and respectful of us, our young child, and our home. The work they have done on our house is second to none. My husband and I will certainly use Eastern Siding for any of our future home improvement needs.

I did some research on various suppliers in the St. John's area. I decided to purchase with the window shop, 10 replacement windows and new front door. Although the wait was longer than I would like, 6 weeks, they more than made up for that with the great installation work! The men were efficient and friendly and went out of their way to clean up as they worked. They replaced what needed to be done and even replaced some steps and wooden railings in the front of the house on their own accord.
