What our customers say

I had windows and doors installed in my home by B. T. Windows and Doors. From the initial contact to the final installation my interactions with Mr. Bilich was short of extraordinary. I found him to be extremely professional and knowledgeable in all aspects of the process. Mr. Bilich is precise in his measurements which result in a smooth installation. Mr. Bilich is a true master craftsman.

I am extremely pleased with the end results and recommend B. T. Windows and Doors to all without hesitation.
