Caulk and Weatherstripping Techniques

Caulk and weatherstripping are tools to seal gaps around doors and windows, improving energy efficiency. Caulk is a flexible, waterproof material applied with a caulking gun to fill cracks and gaps in stationary surfaces like window frames and baseboards. Weatherstripping involves attaching strips of material—such as foam, rubber, or metal—to moving parts like door or window frames to prevent drafts. Both methods reduce air leaks, enhance comfort, and lower heating and cooling costs. Proper application involves cleaning surfaces, selecting appropriate materials, and ensuring a tight seal without over-application for a neat, effective finish.
