Gaps around doors and windows are among the biggest sources of energy loss in your home. Air leaks through these openings can account for 25 to 30 percent of your heating and cooling costs. Weatherstripping is one of the least expensive home improvements you can make, with most projects costing under $50 in materials and delivering immediate energy savings. Here is how to choose and install the right weatherstripping for every application.

Types of Weatherstripping
Different locations require different types of weatherstripping. Understanding the options helps you choose the most effective and durable solution:
- V-strip (tension seal): A durable plastic or metal strip folded into a V shape that springs open to fill gaps. Excellent for the sides and top of double-hung window sashes and along door frames. Lasts 3 to 5 years and handles frequent use well.
- Foam tape: Self-adhesive foam strips available in various widths and thicknesses. Easy to install but the least durable option, typically lasting 1 to 2 years. Best for windows and less-used doors.
- Felt: One of the oldest weatherstripping materials, sold in rolls. Inexpensive but wears out quickly in high-traffic areas. Suitable for the sides and top of door frames in lightly used doors.
- Door sweeps: Mounted on the bottom of the door to seal the gap between the door and threshold. Available in aluminum with rubber or nylon brushes. Essential for exterior doors.
- Tubular rubber or silicone: Hollow or foam-filled tubes mounted along door and window frames. Provides a good seal and lasts 3 to 5 years. Available in multiple colors to match your trim.
- Magnetic weatherstripping: Uses magnetic strips to create a tight seal, similar to a refrigerator door. Excellent for metal doors and casement windows.
Where to Apply Weatherstripping
For maximum effectiveness, weatherstrip all exterior doors on all four sides — the two sides, top, and bottom. Pay special attention to the threshold area, where the largest gaps typically exist. Garage doors benefit from weatherstripping along the sides and top, with a dedicated garage door bottom seal. Windows should be weatherstripped where the sashes meet the frame, between the upper and lower sashes on double-hung windows, and around the edges of casement windows. Do not forget less obvious air leak locations like attic access hatches, pet doors, mail slots, and sliding glass door frames.
Installation Steps
Proper installation ensures the weatherstripping performs as intended and lasts as long as possible:
- Clean the surfaces thoroughly — remove old weatherstripping, paint chips, dirt, and any residue. Adhesive-backed products will not stick to dirty or oily surfaces.
- Measure carefully — cut weatherstripping to the exact length needed. Avoid stretching it during installation.
- Install when temperatures are above 50 degrees Fahrenheit — adhesive bonds better in moderate temperatures.
- For adhesive-backed products, peel the backing as you go rather than all at once. Press firmly and continuously along the entire length.
- For nail-on products, space nails or staples 2 to 3 inches apart for a secure attachment.
- Test the door or window after installation — it should close smoothly without excessive force. Weatherstripping that is too thick will make the door difficult to close and may wear out quickly.
Testing for Air Leaks
Before weatherstripping, identify where your worst leaks are. Hold a lit incense stick or thin strip of tissue paper near window and door edges. If the smoke or paper moves, you have found an air leak. On a windy day, you can often feel drafts with your bare hand. For a more thorough assessment, a blower door test performed by an energy auditor can quantify your home total air leakage and identify the biggest leak locations.
Maintenance and Replacement
Weatherstripping wears out and needs periodic replacement. Inspect it annually and replace any material that is compressed, cracked, torn, or no longer making solid contact when the door or window closes. Keeping weatherstripping in good condition is far more cost-effective than the energy wasted by worn seals.
