Door and Window Draft Protection

Start where you feel the air coming through. For a gap beneath a metal door, compare door sweeps for metal doors and check the mounting method and gap coverage. For leaks around the upper edge or jambs, look at exterior door top and side weatherstripping. If you want something you can move aside without attaching a seal, explore draft stoppers for front doors.

For gaps where the moving sash meets the frame, compare window seals that match the gap size and allow normal operation. To add a seasonal insulating layer across the opening, look at window insulation film kits. Film generally limits opening the covered window while installed, so plan around ventilation and emergency exit needs.

Choose window-and-door caulk for suitable stationary joints, such as the seam between a frame and surrounding trim. Weatherstripping belongs where moving parts meet, such as a door against its jamb. Check the caulk label for surface compatibility, indoor or outdoor use, gap limits and curing time. Keep drainage holes, tracks and moving joints clear.

Measure the length of every edge you plan to seal and the gap with the door or window closed. For a bottom seal, also check door width, thickness and clearance as it swings. Match replacement weatherstripping to the existing profile and attachment method; thicker isn't always better, since an oversized seal can prevent proper latching. For film, measure the full area the kit must cover, including the attachment border specified in its instructions.

Yes. A freestanding fabric draft blocker rests against the inside bottom edge of a closed door and can be lifted away. Browse removable front-door draft stoppers and check the length against your opening. Keep the walkway clear, and remember that a bottom blocker won't address leaks around the top, sides or frame.
