8 DIY Ways To Draft-Proof The Doors & Windows In Your Home

Regardless if your home is brand new or 100 years old, almost every house has a draft. Drafts occur where there are gaps in the construction and the opening is left unsealed to the outside.

Drafts can be found in places such as: windows, doors, attic hatches, pipes leading outside, and ceiling-to-wall joints.

The cold air that enters into your home through these uninsulated spaces can raise your heating bill and allow not just cold air in, but moisture and little critters too. Here are eight simple ways to draft-proof your windows and doors this fall:

1. Use Weatherstripping

Weatherstrips are an inexpensive way to help seal drafty doors and windows. This guide from Lowes can help you knock out this task in a few easy steps.

Level of Difficulty: Easy

2. Install New Sweeps

Replacing old door sweeps with new ones can make a world of a difference. This Old House‘s contractor, Tom Silva, recommends purchasing a wood sweep that can be painted or stained to match your or door.

To ensure a good fit, close the door, measure the length of the door, and cut the size you need. There are a few different kinds of sweeps (like heavy duty, drip-cap and brush) – asking an expert at your local hardware store which one is right for you will help ensure you get the best bang for your buck.

Level of Difficulty: Easy

3. Use Foam Tape

Highly-sticky foam tape is a great weather-proofing alternative to doors that may be slightly warped and don’t have a true and snug fit. Simply cut to size and secure in the areas with a draft.

Level of Difficulty: Easy

4. Apply Rigid Foam Insulation And Foil Stripping

Level of Difficulty: Moderate

5. Apply Window Film

I used interior window film at an old apartment and it worked great. It looks like saran wrap and when put in place and heated with a hair-dryer, shrinks and seals drafty windows. My pro tip: recruit a friend to help hang on larger windows, it’s much easier that way!

Level of Difficulty: Easy

6. Hang Insulated Curtains

Thermal curtains are a great way to retain heat in your home during the winter. The only drawback is to be most effective, they need to be closed. I personally prefer to let in as much light as possible during the winter months, so thermal curtains are not the best solution for me. As a note: thermal curtains do work well in the summer too, as they can help block out the suns’s hot rays.

7. Use A Door Snake

If you have a drafty window or door, these little snakes are a must-have in your home. Placed at the bottom of the door or window, these weighted fabric tubes help block out the unwanted chill. Get the DIY instructions here. Not crafty? Simply roll up a towel and place on the floor. It’s better than nothing.

Level of Difficulty: Easy – Moderate


8. Re-Caulk Your Windows & Doors

Over time, the caulking on windows degrades and may wear or peel away. Each fall, buy a tube or two of exterior caulking and make your rounds on outside of your home. Simply re-caulk old spots to help seal out drafts. Watch the video below for easy DIY tips.
