Owner's background

Tomasz Bilich is the owner operator of the business and has over 10 years’ experience in the residential window and door industry. I pride myself and the business on the quality of workmanship, hard work ethic and friendly customer service. I learned about windows and doors when I began working in the factory at a local window manufacturer 25 years ago. I learned from the bottom up of the manufacturing process; from production to post installation service and eventually learning the installation process. This has enabled me to offer my customers quality workmanship, extensive product knowledge and help them design their window and door projects to enjoy their homes.

One-on-one personalized customer care

What makes B.T. Window and Doors, LLC unique is you’ll get one-on-one personalized service. We are not a large corporation, our level of service and quality workmanship surpasses larger companies. No matter how advanced the glazing and framing materials might be in a window unit or how beautiful a new door can be, ultimately the performance depends on the quality of installation. Poor installation can contribute to air leakage, heat loss, condensation and water leakage. We are here to save you time, money and provide you with peace of mind your project was done properly.
