Installation Process

Your existing windows are cracking and peeling. You can’t get bedroom windows all the way open for fresh air on long summer nights. In cold weather months, a draft coming through your front window chills you to the bone. You know you need replacement windows, but you wonder what to expect in the installation process. Once you select a Milgard Certified Dealer, replacing your existing windows and patio doors is an easy and hassle-free four-step process.

The Perfect Solution for Any Home

An important consideration when choosing replacement windows and doors is the exterior finish of your home. Our products can be installed in just about any type of home, whether it’s made of wood, brick, or even stucco.

By using a portion of the existing frame, these windows give your home a new look without costly or time-consuming siding repairs. They install quickly and provide a weather-tight seal.
