Why Every Homeowner Should Check Their Weatherstripping This Fall

Feel a chill near your front door even when it's closed?
You're probably not imagining it. Weatherstripping, the thin, flexible material that seals the gaps around your doors and windows, is one of the hardest-working, least-noticed parts of your home. And when it fails, it fails quietly: a little cracked foam here, a flattened strip there, until suddenly your furnace is working overtime just to keep up. With cooler weather on the way, now's the moment to give it a quick check before winter makes the problem impossible to ignore.

Why it matters

A properly sealed door or window is doing more work than you'd think:

•Eliminate the drafts and cold spots that make one room feel colder than the rest.

•Take pressure off your furnace and lower heating and cooling costs.

•Keep dust, pollen, and moisture from sneaking indoors.

•Close off the gaps insects, spiders, and small rodents use to get inside.

•Quiet things down by softening outside noise.

Signs it's time to replace your weatherstripping

Not sure if yours is due for a refresh? These are the telltale signs:

•You can feel a draft around a closed window or door.

•Daylight is visible around an exterior door.

•The weatherstripping is cracked, brittle, torn, or flattened.

•Your door no longer seals tightly when closed.

•You notice insects entering around doors or windows.

A simple test

You don't need any tools to find out, just a dollar bill. This is often called the "dollar bill test": close the bill in the door and give it a tug. A good seal will grip it and hold it in place. If it slides right out, your weatherstripping has stopped doing its job.

What you'll need

•Replacement weatherstripping (available at most hardware stores)

•Tape measure

•Scissors or utility knife

•Cleaning cloth

Most weatherstripping jobs are a straightforward, low-cost DIY project. If you've never done it before, a quick video tutorial from your hardware store's website or YouTube will walk you through the exact steps for your door or window type in about ten minutes. And if the gaps turn out to be bigger than weatherstripping can fix, such as a warped frame or a door that doesn't hang right, it's worth calling in a handyman rather than trying to force a seal that won't hold.

According to the U.S. Department of Energy, simply sealing the gaps around your doors and windows can lower heating bills by 10–15%. That's a meaningful savings for a job that takes most homeowners less than an afternoon. If your home hasn't had its weatherstripping checked in a few years, this fall is the ideal time to close that gap, literally and financially, before the cold sets in.
