What are our happy customers saying about us?

Very pleased that we selected B.T. Windows and Doors to replace all 24 windows in our house, 2 sliding glass doors, and our front door with transom and sidelights. Tomasz was very reliable and helpful to work with and his crew did a great job. They protected our new floors inside our house while installing and kept everything very clean overall. They worked around our schedule to make the installation very simple. We really like the top quality sliding glass doors and front door made by Provia, which Tomasz highly recommended. Very impressed with how they make everything look so easy and I'd highly recommend them to everyone.
Thank you B.T. Windows and Doors!

It was a pleasure working with you. We really like our new windows, they open and close so easily. We noticed a difference in the winter and also when it's hot outside. They are definitely energy efficient. We had other estimates and looked at many other options. Your window quality is the best and so were your prices.
We liked that the installation went quickly and that you were there to supervise. Your installers were very professional, friendly, and cleaned up after each installation. We will definitely recommend you.
Thank you for your services and helping us choose the right windows for our home.
