How to rid your home of drafts

A home that is full of drafts is inefficient and expensive. And drafty homes are not just a problem when the weather is cold, as air that seeps in when you’re trying to keep the home cool can be an inefficient nuisance as well. Higher energy bills and wasted resources do not have to be tolerated if you simply scour your home for drafts, sealing them to cut energy costs and make the home more comfortable.


Homes that feature attics with pull-down stairs tend to be drafty. In such homes, a large hole is cut out of the ceiling so residents can access the attic. So instead of thick insulation, these homes may only have a sheet of plywood blocking your interior space from the outdoors, as many attics are directly vented to

if there is a leak, turn on the attic light, close the attic door, and check to see if you can see the light on from below. If you can, then there is a gap letting both the light and air escape. In addition to using flexible rubber around the opening of the attic to better seal the door when it is closed, you can think about adding a thicker, more insulated door.

Dryer vents

The standard home laundry dryer vents outdoors via an exhaust duct. This duct is open to the outdoors, and it may be letting cold air into the home. That’s because there is typically a flimsy flapper made of sheet metal on the outside of the vent to help protect against air infiltration. But over time dryer lint can accumulate at the vent opening, causing the metal flapper to stay open when it should close. Homeowners can invest in dryer seals that close the vent when the dryer is not in use. Not only does this prevent cold air from entering the house, but also it keeps out pests, like bugs and rodents.


Check pipes that exit the home, such as those that feed outdoor water spigots, as such pipes can let cold air back into the house. The same can be said for waste pipes. Also, check to see if pipes that connect to garages, basements and crawl spaces are not insulated. Use sealant around these pipes to block drafts into the home. Foam insulation can be sprayed into small crevices, where it will expand and harden, blocking off air access.

Electrical outlets

Outlets and light switches can be significant sources of drafts in a home. Check to see that the switch plates are secure. If drafts still come through, then employ outlet draft blockers to prevent cool air from entering the home and warm air from exiting it.
