2. Window Removal & Installation

On the day of installation, our window specialists will then remove your home’s current window(s) cautiously, without causing any damage to your home’s structure. After, the custom replacement windows you selected will be accurately installed with antimicrobial coils that prevent damaging mold from developing throughout your window’s lifespan.

3. Sealing Your Window

Once the replacement windows are in place, XL Building Products uses closed cell foam to shim and square the window, preventing whistling air and extreme temperatures from seeping through. Exterior silicone foam is then caulked between the window space and newly installed window ensuring your window investment does not expand or shrink over time. Unlike many other window replacement services, our fine-tuned sealing process utilizes premier products of the highest commercial grade for the years to come.
