Article Summary: 

This article provides a guide on how to repair a broken seal on a window. It covers the three types of window seals, which include silicone caulking, weatherstripping, and insulated glass unit (IGU) seal, and how to repair them. For cracked silicone caulking, the article recommends using silicone sealant, a putty knife, and a soft rug to remove and replace the caulking. For failing weatherstripping, foam-type weatherstripping, a soft rug, and a tape measure are needed. However, a broken IGU seal requires the assistance of a professional to install a new seal. The article suggests that in some cases, replacing the entire window may be more cost-effective.
