Window Seals: A Comprehensive Guide for Homeowners
Window seals are the thin, flexible strips of material that line the edges of a window frame. Their primary function is to produce a weather‑tight seal, avoiding drafts, water seepage, and energy loss. Over time, direct exposure to sunlight, temperature variations, and wetness can trigger seals to split, shrink, or lose adhesion. When this occurs, the performance of a window declines, leading to higher energy bills and pain inside the home. Changing window seals is an uncomplicated DIY task that can bring back a window's efficiency and extend its life span.
Why Replace Window Seals?

Maintenance Tips
- Inspect seals every year for indications of wear, particularly after severe weather condition seasons.
