This Valentine’s Day, remember to extend some love to your home! You can easily give your heating system a break by sealing any air leaks, helping to keep your home at a comfortable temperature. Fixing air leaks is an inexpensive and simple DIY project – your wallet will send its love right back to you!
If you feel a cold draft flowing through your home this winter, start by checking these common locations where air infiltration can occur:
- Doors – Do you notice any light coming from around or under your doors? If so, you probably have an air leak. Replace your door’s weather-stripping or door shoe threshold.
- Light switches and outlets – Switches and outlets on exterior walls can let cold air in. Apply foam gaskets around switches and outlets to provide insulation.
- Attic access hatches – Attic access hatches are seldom weather‑stripped. Install foam gaskets around the edge of the attic opening to stop heat from leaking out of your home and into your attic.
- Plumbing locations – Wherever a pipe protrudes through a wall, air can flow. Spray foam sealant between the drywall and the pipe to help prevent air leakage.
- Windows – While most windows are weather-stripped or caulked, the original stripping or caulking could be getting old and losing its effect. Apply new caulking and weather‑stripping so no drafts come from your windows.
