Air escapes through every hole and crack in your home. Warm air leaking into your home during the summer and out of your home during the winter can waste a lot of your money. One of the quickest and cheapest dollar saving tasks you can do is caulk, seal, and weather strip all seams, cracks, and openings to the outside.
Tips for Sealing Air Leaks:
1- First, test your home for air tightness. On a windy day, carefully hold a lit incense stick next to windows, doors, electrical boxes, plumbing fixtures, attic hatches, and other locations where there is a possible air path to the outside. If the smoke streams horizontally, you’ve located an air leak that may need caulking, sealing, or weather-stripping.
2- Caulk and weather strip doors and windows that leak air.
3- Caulk and seal air leaks where plumbing, ducting, or electrical wiring penetrates through walls, ceilings, and soffits over cabinets.
4- Install foam gaskets behind outlet and switch plates on walls.
5- Look for dirty spots in your insulation, which often indicate holes that allow air leaks. You can seal the holes with low-expansion spray foam made for this purpose.
6- Look for dirty spots on your ceiling paint and carpet, which may air leaks at interior wall/ceiling joints and wall/floor joists. These joints can be caulked.
7- Use foam sealant around larger gaps around windows, baseboards, and other places where air may be leaking out.
8- When you’re not using your fireplace, keep the flue tightly close. Inflatable chimney balloons are designed to fit beneath your fireplace flue during periods of non-use. They’re made from plastic and can be removed easily and reused hundreds of times.
About one-third of leaking air infiltrates through openings in your ceilings, walls, and floors. Take a Saturday morning to check your air leaks – it will be well worth your time and savings on your next electricity bill.
