What are our happy customers saying about us?

My experience with B.T. Windows & Doors was fantastic - I can't say enough positive things about Tomasz (owner) and his team! We recently had 14 windows installed at our home, and from start to finish the whole experience was pleasant and informative. Tomasz went the extra mile to make sure we had all the information we needed to make the right decisions on our windows, and he made the process so easy with his professionalism and knowledge.
I have worked with numerous contractors over the years for various things, and I can honestly say that B.T. Windows & Doors ranks at the top. From planning to install, everything was done in a timely manner and with precision. The price was fair and we couldn't be happier with the final product - the workmanship was excellent! We will definitely use them in the future for additional work. - Nick Richards, March 2024

What a great experience! They will take care of you and do it right! No sales schemes or hidden agendas. B.T. Windows and Doors LLC worked with us to find what we needed at a fair price. Install day they were early, arrived ready, and had 13 windows and Bow Window replaced in less than 8 hours. Quality work. Tomasz took time to explain how the windows were being installed and insulated. No trash or debris was left behind. They have an amazing crew that worked very well together, and the end result is beautiful. Thank you! - Michael Wood, Feb 2024
