How to Prevent Air Leaks Around Windows and Doors in Texas Homes

The Most Common Places Texas Homes Lose Air

The Best Ways To Close Small Gaps

If old caulk has split or separated, scrape out the failed section before applying a new bead.

Entry doors and patio doors usually lose air at the perimeter, the threshold, or the latch side. Check the strike, refresh the sweep, and make sure the perimeter seal compresses evenly.
