Seal Replacement: A Complete Guide for Homeowners
Window seals are the unsung heroes of a home's envelope. They keep outside air, moisture, noise, and dust out while maintaining indoor comfort and energy efficiency.

When that occurs, drafts, higher utility expenses, and even water damage can follow. This guide strolls you through the entire procedure of replacing window seals-- from identifying the issue to selecting the right products and choosing whether to deal with the job yourself or call an expert.
