An Air Leak Checklist For Your Home
When your heating system has less work to do to keep you warm, you use less energy and your fuels costs decrease. One way to make this happen is to identify places where cold air from the outside infiltrates your home.
For instance, you can seal cracks in exterior walls and put weather stripping and caulk around windows and doors where air might be sneaking through.
If you’re handy, you can tackle many of these jobs yourself, but don’t be shy about calling for the advice of a professional. If you’re not comfortable with anyone visiting your home just yet, just call so you can get on their list when our lives return to some sense of normalcy.
How To Find Drafts In Your Home
A sensible place to begin your search for air leaks is to go to rooms that feel colder than the rest of the house. Try using a flashlight at night to look for gaps in your home’s outer surfaces. Turn the lights out, then have someone stay in a room while you shine the light from the outside; if light comes through a hole or gap, you have found the source(s) of your leak. Try this with windows, doorways, at-house corners and joints, and even on floorboards.
Some draft issues can be handled easily by using caulk, door sweeps, or weatherstripping; other problems may be more complex. Consider hiring a qualified technician to conduct a comprehensive home energy audit – particularly a blower door test. This test depressurizes a home, revealing the location of many leaks. A professional home energy audit will also help determine areas in your home that need more insulation.
If you have a warm-air furnace (instead of a boiler), you may also want to consider getting your ductwork inspected to see if you have leaks that can be sealed.
Once these problem areas are identified, you can address them to enjoy more comfort and better home energy efficiency.
Air Leak Checklist
Here’s part of a checklist provided by the U.S. Department of Energy (DOE). You can find more energy efficiency and air leak tips on their website
- Caulk/weatherstrip gaps around doors and windows.
- Seal air leaks where plumbing, ducting, or electrical wiring comes through walls, floors, ceilings, and soffits over cabinets.
- Install foam gaskets behind outlet and switch plates on walls
- Look for stains on your ceiling paint and carpet, which may indicate air leaks at interior wall/ceiling joints and wall/floor joists, and caulk them.
- Cover single-pane windows with storm windows or replace them with more efficient double-pane low- emissivity windows.
- Use foam sealant on larger gaps around windows, baseboards, and other places where air may leak out.
- Cover your kitchen exhaust fan to stop air leaks when not in use.
- Replace door bottoms and thresholds with ones that have pliable sealing gaskets.
- Keep the fireplace flue damper tightly closed when not in use.
