Inspect windows and doors regularly to stop air leaks and water seeps that create high energy and repair bills. We’ll show you how.
Take a look at windows, doors and skylights to stop air leaks, foil water drips, and detect the gaps and rot that let the outside in and the inside out. You can perform a quick check with a home air pressure test, or do a detailed inspection. Luckily, these inspections are easy to do. Here’s how to examine the barriers that should stand between you and the elements.
Big picture inspection
A home air pressure test sucks air into the house to reveal air leaks that increase your energy bills.
To inspect windows and other openings:
Seal the house by locking all doors, windows, skylights, and shutting all vents.
Close all dampers and vents.
Turn on all kitchen and bath exhaust fans.
Pass a burning incense stick along all openings—windows, doors, fireplaces, outlets—to pinpoint air rushing in from the outside.
Windows and the outside world
Air and water can seep into closed widows from gaps and rot in frames, deteriorating caulking, cracked glass, and closures that don’t fully close.
To stop air leaks, pinpoint window problems.
Give a little shake. If they rattle, frames are not secure, so heat and air conditioning can leak out and rain can seep in. Some caulk and a few nails into surrounding framing will fix this.
Look deep. If you can see the outside from around—not through—the window, you’ve got gaps. Stop air leaks by caulking and weather stripping around frames.
Inspect window panes for cracks.
Check locks. Make sure double-hung windows slide smoothly up and down. If not, run a knife around the frame and sash to loosen any dried paint. Tighten cranks on casement windows and check that top locks fully grab latches.
Door doubts
Check doors for cracks that weaken their ability to stop air leaks and water seeps.
Inspect weather stripping for peels and gaps.
Make sure hinges are tight and doors fit securely in their thresholds.
Inspect skylights
Brown stains on walls under a skylight are telltale signs that water is invading and air is escaping. Cut a small hole in the stained drywall to check for wetness, which would indicate rot, or gaps in the skylight.
To investigate skylight leaks, carefully climb on the roof and look for the following:
Open seams between flashing or shingles.
Shingle debris that allows water to collect on roofs.
Failed and/or cracked cement patches put down the last time the skylight leaked.
