Resealing window frames takes an afternoon and costs under $30. It’ll stop drafts, keep out moisture, and put money back in your pocket every month. Plus, there’s something deeply satisfying about eliminating that one annoying draft for good.
For a crisp, professional line, run painter’s tape along both sides of the gap, leaving just the joint exposed.
Peel off the painter’s tape while the caulk is still wet. Allow the seal to cure for as long as the manufacturer recommends (usually 24 hours) before exposing it to rain or extreme temperatures.
Cut the nozzle at a 45-degree angle. Start with a small hole—you can always cut more. Puncture the inner seal with a long nail or the built-in poker on most caulk guns.

There’s nothing quite like curling up next to a window on a chilly morning—unless a blast of cold air is hitting you in the face. Over time, the seals around your window frames crack, shrink, and pull away. The result? Higher energy bills, musty smells from moisture, and a less comfortable home.
Use your putty knife to scrape away any loose, peeling, or hardened old caulk. You want a clean, bare surface for the new sealant to stick to. Vacuum out any dust or debris.
