“Recently had an old box bay window replaced with a new garden window from Stanek Windows. Quality materials and craftsmanship with excellent installation services, all at a reasonable price.

“We are totally satisfied! Our installer was absolutely a top notch professional! His attention to detail and perfection was amazing. We love our windows and have had many compliments. The sales representative who visited us prior to going with Stanek, was also professional, easy to understand and actually did a demo with the sample piece of window that we were interested in. He used a high intensity heat gun behind the sample to demonstrate that the windows do not get hot on the inside when the sun is beating on them. Since we've had very hot weather and the sun beats on our front windows all day, I find myself going to those windows to touch them, and they're cool on the inside as well as our window sills. We are very happy.” – Joyce W., McKees Rocks, PA | September 8, 2016 * * * * *
