We recently purchased and had installed approx 40 Provia windows & a front entry door from B.T. Window & Doors. We would like to thank Tomasz & Wladek for the most pleasant purchase and renovation experience. From the time we met for a quote to the completion of the job, both held 100% true to their word.
The staff/crew were the most professional, knowledgeable & respectful I have seen in my 20+ years prior in the building industry.
I would highly recommend this company to anyone looking to replace windows and/or doors, from a small job to a large job.

B T Windows and Doors have been a tremendous group to work with. They replaced 22 windows and a sliding glass door for us. Their pricing was excellent and their installation crew did a magnificent job. We couldn't be more pleased. We highly recommend them!

After researching with 3 other “big TV firms” I found an excellent guide that referred me to certified installers in my area. BT Windows came out with a no pressure, knowledgeable, and professional measuring. Their proposal was the BEST value for 9 windows and a sliding door! Installation day was seamless, techs arrived on time, great installation, answered all my questions and cleaned up very well both inside and outside. I will definitely call them for the next phase of replacement windows and doors.
