How to Weatherproof Your Home for Winter

May 1

Weatherproofing your home before winter hits can make a huge difference in comfort and energy bills. By sealing leaks, improving insulation, and optimizing airflow, you help your HVAC system operate more efficiently and keep the heat where it belongs—inside.

1. Seal Windows and Doors

Use weather stripping, caulk, or foam tape to seal gaps around frames. According to the Department of Energy, this can reduce drafts and energy use by up to 20%.

2. Add Insulation Where It Counts

Attics are a top priority—heat rises and escapes without proper insulation
Crawl spaces and basements often need attention too
Use foam gaskets behind outlets on exterior walls to stop heat leaks

3. Install Door Sweeps and Draft Stoppers

These low-cost tools block cold air from seeping under doors. You’ll notice a difference in comfort immediately.

4. Use Heavy Drapes and Area Rugs

Thermal curtains reduce heat loss through windows. Rugs on hardwood or tile floors add insulation and make your space feel warmer.

5. Schedule an Energy Audit

Professional HVAC contractors (like Decker!) can identify leaks, check insulation, and test your system’s efficiency. With this insight, you’ll know exactly where to improve.
