Self-Adhesive Weatherstripping
Useful for compatible door and window gaps. Match the profile and compression range to the opening instead of assuming one thickness fits every frame.

How to Weatherstrip Doors & Windows
Find common drafts, choose a seal that matches the gap, and improve the fit around doors and windows without preventing them from opening, closing or latching properly.
Before you start
Weatherstripping works best when the product matches the opening, surface and size of the gap. Inspect the existing seals first, measure before buying or cutting material, and follow the weatherstripping or sealant manufacturer's surface-preparation and installation instructions.
Do not cover intentional drainage openings, weep holes, ventilation paths or required clearances. Repair damaged frames, glass, locks or water-intrusion problems rather than trying to hide them with weatherstripping.
Project checklist
- Find likely draft areas. Inspect the perimeter of doors and operable windows, especially worn seals, corners, meeting rails and the bottom of exterior doors. A suitable draft-detection tool can help compare areas, but temperature differences alone do not prove an air leak.
- Measure the opening and gap. Record the length you need and estimate the gap size at several points. Choose weatherstripping designed for that type of door or window and within the product's stated compression range.
- Remove failed material and clean the surface. Take off loose or deteriorated seals and adhesive residue as appropriate. Clean and dry the mounting surface according to the new product's instructions.
- Install the weatherstripping. Cut pieces carefully, fit corners neatly and press or fasten the material as directed. The seal should make contact when closed without making the door or window difficult to operate.
- Address the bottom of the door. If needed, install an appropriately sized door sweep while maintaining proper door movement and any required threshold or drainage clearances.
- Seal suitable small seasonal gaps. Where appropriate, use a removable gap-sealing product according to its instructions. Avoid sealing moving joints or openings that the manufacturer says must remain clear.
- Test the result. Open, close and latch the door or window several times. Check for binding, loose material and remaining obvious gaps, then adjust as needed.

Door Sweep
Helps reduce an appropriate gap at the bottom of an exterior door. Measure the door first and confirm the sweep will not interfere with the threshold or normal operation.
View on AmazonRemovable Gap-Sealing Caulk
An option for suitable small or seasonal gaps when permitted by the product instructions. Keep it away from intentional drainage and ventilation openings.

Can help compare surface temperatures and identify areas worth inspecting more closely. Use the readings as a diagnostic clue rather than proof of a specific leak.
View on AmazonTips for a better seal
Start with the most obvious worn or missing seals, keep adhesive surfaces clean and dry, and test operation as you work. More compression is not always better: oversized weatherstripping can make a door difficult to latch or prevent a window from closing correctly.
