Window seals are the weatherstripping and caulking materials that keep air leaks and moisture out of your home. Over time, seals crack, shrink, or pull away from the frame, letting cold air in during winter and hot air during summer. Replacing worn seals is one of the cheapest ways to lower heating and cooling costs and stop drafts before they become a bigger problem.
These articles cover what types of seals work for different windows, how to spot damage that needs fixing, and whether you should replace seals yourself or hire someone. You'll learn the difference between weatherstripping and caulk, what materials last longest, and how to measure and install new seals correctly.
