Window Replacement Specialists You Can Trust!

Windows replacement in the Pittsburgh region for over 40 Years!

We are window replacement specialists offering the best window installation services in the greater Pittsburgh area for 40 years as of March, 2013. We install windows and doors in Pittsburgh homes and businesses in a wide variety of sizes and styles, by top window manufacturers. We offer windows (and doors) by Andersen, Marvin, and Pella, and more. We install aluminum windows, fiberglass windows, and wood windows.

We isolate the work as much as possible by keeping room doors closed, or using tarps, to prevent the rest of the building from getting too cold. We are careful to avoid tracking in snow and mud, and we clean up after every project as if we were our own home or office.

Our Windows Installers are InstallationMasters™ Certified Installers

The Window Installation Specialists installers are all certified InstallationMasters™, so you know they have significant window installation experience and are properly trained and skilled; they are technically carpenters. Our installers are specialists who have also completed nationwide training and certification replacement windows and exterior glass doors in residential and light commercial markets.

Our window replacement experts care about their work. Unlike many of our window replacement competitors, our window installers are not independent contractors, but full-time employees of Window Installation Specialists. Our uniformed window installers are fully insured with general liability, auto, and worker’s compensation too.
