When replacing your windows, it’s important to consider more than just the style, material or energy efficiency rating. Specifically, the installation method you choose can have a major impact on your windows’ long-term performance, durability and protection against moisture. Here’s some information about the two most common methods:
Retrofit installation
A retrofit installation places a new window into the existing frame and seals it against the exterior of the home. This is often a quicker and more affordable option that requires less disruption to the existing structure, but keep in mind that it may not address issues with the original frame, flashing or waterproofing.
Full-frame replacement
I recommend a full-frame replacement whenever possible. This process involves removing the existing window frame and installing a new window with updated flashing, waterproofing materials, and exterior trim. It provides better protection against water intrusion, helps reduce the risk of condensation and moisture damage, and recreates the home’s original construction process for a more complete installation.
The right choice for your situation depends on factors like the condition of your existing windows, your home’s construction and your long-term goals. An experienced window professional can help you determine which installation method provides the best performance and value.
