How to Fix Drafty Windows
Published: February 15, 2013
Here are some quick, inexpensive fixes you can do now, plus more permanent solutions when you have the time and money.
What’s Wrong with My Windows?
With old windows, the glazing putty may have grown brittle and fallen away, leaving the glass rattling in place. Double-hung sashes of wood windows can shrink with age and wear, letting in cold air. Even newer vinyl or aluminum windows may have worn-out gaskets and weather stripping.
On a cold or windy day, you’ll be able to feel where your windows are leaky just using your hand. Here’s more information on how to detect air leaks.
Once winter is in full swing, it may be difficult to get outdoors to make permanent fixes. Here are fast interior solutions to get you through the colder months:
- Apply V-seal weather stripping. For an easy fix, add this plastic weather stripping along the sides of the sashes. Windows can open and shut even with the V-seal in place. Cost: $5.50 per window.Related:Tips on Replacing Weather Stripping
- Add rope caulk. Old window sashes shrink with age, leaving plenty of room for drafts. For a quick fix, apply rope caulk to any cracks. This soft, sticky stuff can be molded to suit the gap — and removes easily at the end of the season. Cost: $5 for 30 feet
