Plus, adding insulation to your home is one of the best investments you can make. A well-insulated home retains more heat in the winter and stays cooler in the summer, which means your HVAC system won’t have to work as hard. The result? Lower energy bills and a more comfortable living space.

12 Tips for DIY air sealing to reduce energy consumption and improve insulation:

1. Seal Windows and Doors 

Windows and doors are often the biggest culprits for air leaks. Use weatherstripping or caulk to seal gaps and improve your home energy efficiency.

2. Check Baseboards 

Inspect the seams of your baseboards for any cracks. Sealing them with caulk can prevent air from escaping, adding to your home’s insulation.

3. Inspect Vents and Outlets 

Use outlet insulators to stop air leaks around electrical outlets, switches, and vents. This is a quick fix to reduce energy consumption.

4. Use Incense to Find Hidden Air Leaks

 Light a stick of incense and hold it near potential leak areas. If the smoke doesn’t rise straight, you’ve found a draft. This method can help you discover hard-to-find leaks around your home.

5. Seal Gaps Around Pipes and Wires 

Any place where pipes or wiring come through walls can have gaps that let air in or out. Use expandable foam or caulk to seal these areas.

6. Check Your Ductwork 

Leaky ducts can cause you to lose heated or cooled air. Make sure to seal any seams or holes in your ductwork using foil duct tape or mastic tape for long-lasting results.

7. Use Weatherstripping for Sliding Doors 

Sliding doors can be a big source of drafts. Install weatherstripping to keep air from escaping and improve your home’s overall insulation.

8. Add Thresholds to Doors 

Installing door thresholds can help block drafts from entering under doors, further reducing energy consumption.

9. Insulate Attic Access 

Don’t forget about your attic! Make sure the access door or hatch is properly sealed to stop warm air from escaping into the attic during the winter.

10. Seal Around Chimneys 

Chimney flues can be another source of air leaks. Ensure your flue is closed tightly when not in use and check for any gaps around the chimney.

11. Use Outlet Insulators 

These inexpensive foam gaskets fit behind outlet and switch plates, helping to prevent drafts and improve your home’s insulation.

12. Maintain Your HVAC System 

A dirty HVAC system can lead to higher energy bills. Regular maintenance, like changing filters and cleaning ducts, ensures your system runs efficiently, complementing your DIY air sealing efforts.
