Pella Window Installation in Lemont
We were recently contacted by a customer from Lemont, Illinois. He had purchased a new window from Pella, but for unforeseen reasons, the supplier was unable to complete the installation. The customer needed a company that could take on the job and complete it professionally on a tight schedule.
Our specialists promptly arrived at the site, assessed the condition of the window opening, and prepared everything needed for proper installation. Thanks to our experience working with Pella products, the installation went smoothly, and the customer received a perfectly installed window that fully met the manufacturer’s specifications.

How Pella Window Installation Works
- Assessing the opening and preparing the work area: we check the dimensions, the condition of the frame, the moisture level, and the insulation.
- Removing the old window: we carefully remove the sashes and frame, and clean the opening.
- Preparing the opening for the new window: leveling, sealing, and installing support blocks.
- Installation of the Pella window: we level it, secure it with fasteners, and check for a tight fit.
- Insulation and sealing: we use materials recommended by the manufacturer to maintain the warranty.
- Finishing work: installation of window trim, checking sash operation, and cleaning the work area.
Every window manufacturer in the U.S. has specific installation requirements. If these requirements are not met, the new window will not be covered by the warranty. That is why it is so important to hire a trusted professional who can demonstrate their expertise. Rotten Window Repair professionally installs windows from various American brands: Andersen, Pella, Marvin, Semco, Jeld-Wen.
