Use Caulk to Keep Indoor Air From Escaping

Refreshing the caulk around your windows and doors is one of the simplest ways to maintain your home. Good caulking helps keep indoor air inside and stops insects from slipping through small gaps. Over time, caulk can dry out and crack, creating openings that let air escape and pests enter. Fixing it is low-cost and can help reduce your energy bill.

Make it a habit to inspect all windows and doors, inside and outside, and replace any caulk that is peeling or worn. Caulk made for damp areas is also ideal for bathrooms—sealing the sink, tub, and toilet prevents moisture from reaching walls and flooring, helping you avoid mold and mildew problems.
