The Window Installation Process

Curious about the process of installing replacement windows in Chester County, PA? Our contractors will first inspect the locations of the existing window openings to check the fit of the new windows. If windows already exist, installers will remove any existing windows and clean up the area. 

After the old windows have been removed, we will inspect the window frames and surrounding areas for damage and rot. We’ll set the new window in place and repair it if necessary so that it fits securely.

Insulation will be applied around the window frame to prevent drafts from the fluctuating West Chester, PA weather and improve energy efficiency. We’ll also apply caulking or weatherstripping to seal any 

gaps between the window frame and the wall. We finish the installation process by working on the trim and any finishing touches so you’re left with beautiful windows in Berwyn, PA
