WEATHER-STRIPPING: WHAT IS IT AND WHY USE IT?!

July 23rd, 2025

By: BC Building Science

Until you need it, or need to replace it, weather-stripping is something you may not know much about, but it is a hardworking and essential home maintenance product.  Weather-stripping is used to seal gaps around doors and windows to prevent air, water, insects, and debris from entering your home.  And don’t forget that once installed, seasonal checks are necessary to ensure that existing weather-stripping is still in good shape and continuing to do its job.
