Stopping Drafty Windows and Doors
Drafty windows and doors are one of the most common energy wasters in residential homes. These air leaks make your heating and cooling systems work harder, leading to higher utility bills and inconsistent indoor temperatures. The good news is that you can easily identify and seal these drafts using simple materials and tools found at any home improvement store.
Step-by-Step Guide to Fixing Drafts:
1. Perform a Draft Test
On a windy day, hold a lit incense stick or candle near the edges of your windows and doors. If the smoke moves, you’ve found a draft. Note the locations carefully.
2. Inspect and Replace Weatherstripping
Old or missing weatherstripping is the number one cause of air leaks. Peel back existing strips and replace with adhesive-backed foam or rubber strips. Make sure it seals tightly when the window or door is closed.
3. Add or Replace Door Sweeps
Install a door sweep along the bottom of exterior doors to block air from coming in underneath. Most models screw into the door and are easily adjustable.
4. Seal Gaps with Caulk
Use caulk to seal gaps and cracks around window and door frames, especially where the trim meets the wall. Use exterior-grade caulk for outside gaps and paintable latex caulk indoors.
5. Insulate Windows with Shrink Film
For old single-pane windows, apply window insulation film during colder months. This clear plastic creates an airtight seal when shrunk with a hairdryer.
6. Add Draft Stoppers for Interior Doors
Use a fabric draft stopper at the base of interior doors that lead to colder spaces like basements or garages.
7. Tighten Locks and Latches
Loose locks prevent windows and doors from closing fully, allowing air infiltration. Tighten or replace hardware to improve seal integrity.
Maintenance Tip:
Make draft inspections part of your seasonal home maintenance schedule. Addressing small air leaks can reduce heating and cooling costs by up to 20 percent.
