If your windows are doing a bad job at keeping out the cold, don’t worry: you won’t have to spend hundreds of dollars for an inspection and full-scale replacement from Home Depot. There are a number of things you can do to take care of “leaky” windows (you’ll probably end up going to Home Depot, or perhaps http://sollex.co.uk). Here are five tricks to fix drafty windows.
When you’re sure it’s your windows that are letting in the cold air, remove the interior trim and spray insulating foam into the space between the window framing and the jam. The tube allows for precision spraying, so you won’t be wasting foam. While the trim is removed, you can also caulk the window trim, both on the inside and the outside, to provide additional resistance to air loss. This also adds the benefit of protection against water damage.
2. Out With The Caulk, In With The New
Still on the subject of caulk, if you’ve already got caulk in your window trim and it’s still not doing a good job of keeping the drafts out, it might be time to replace the caulk. Use caulk softener to help get rid of the old caulk, clean the surface, and apply a newer, fresher layer in its place. New caulk will take about 12 hours to set, after which your windows should be drafty no more.
3. Plastic Film
Plastic film doesn’t cost an arm and a leg, and can save up to 55% of the heat in your home from being lost. Simply attach the film to a window using double-sided tape, and seal it in place with a hair dryer. You can even use bubble wrap instead of plastic film.
4. Draft Snakes
Probably the easiest (and quickest) fix on this list is to buy, or even make, a draft snake. It could be a rolled-up old towel, it could be an old tube sock stuffed with rice – however you decide to make your draft snake, just use it to cover the gap in your drafty windows through which the cold air sneaks through.
5. Rigid Foam
You don’t need to see out of every window, so for the ones in your basement and attic that are leaking air, just cover them over with rigid foam. The foam can easily be attached to glass with gentle pressure, and comes off just as easily when you want to let in a little sunlight.
