Seal Windows and Doors – Keep the Chill Out and Savings In
As cooler air settles into the Southeast, keeping your home cozy and energy-efficient becomes a top priority. Even small gaps around windows and doors can let in cold drafts, forcing your heating system to work overtime and driving up energy costs. The good news? Sealing those leaks is simple, affordable, and makes a big difference in comfort and savings.
Follow these steps to seal your windows and doors before the temperatures drop:
Step 1: Find the Drafts
Start by checking for air leaks on a breezy day. Run your hand slowly around window frames and door edges to feel for cool air coming through. You can also use a candle or incense stick—if the flame or smoke wavers, you’ve found a leak.
Step 2: Inspect Weatherstripping
Examine the weatherstripping on all doors and windows. Look for cracks, gaps, or areas where it’s pulling away from the surface. If it’s worn or brittle, replace it with new weatherstripping to create a tighter seal.
Step 3: Caulk Around Frames and Trim
Old caulk can dry out and crack, allowing air to sneak in. Scrape away any damaged caulk and apply a fresh bead around window frames, door trim, and where siding meets your home’s exterior. Choose an exterior-grade caulk for best results.
Step 4: Install or Replace Door Sweeps
Don’t overlook the gap beneath your exterior doors. Adding or replacing a door sweep helps block drafts and keeps warm air inside. Look for a sturdy, flexible option that seals tightly against the threshold.
Step 5: Close Storm Windows (if you have them)
If your home has storm windows, now’s the time to close them. They provide an added layer of insulation that helps reduce heat loss and keeps your home more comfortable throughout fall and winter.
Make window and door sealing part of your annual fall
maintenance routine. It’s a small investment of time that pays off in lower
energy bills, increased comfort, and a more market-ready home when it’s time to
sell.
