When it comes to St. Louis home upkeep, how often do we think of weatherstripping? It can make a drastic difference in how well our doors work. Drafty, inefficient openings in our homes lead to energy, cost and comfort issues. Hereโs what you need to know about weatherstripping and what signs point to needing to replace it.
What is Weatherstripping?
No matter how it looks or what itโs made of, the purpose of weatherstripping is to prevent air leaks. Itโs likely your doors already have weatherstripping in one or more of the following ways:
- Foam tape that runs along the inside of the frame
- Metal or vinyl strips alongside the tops and sides
- Rubber gaskets located between the door and its jamb (i.e., the top and/or bottom sections)
Since energy-efficient door technology has evolved over the years, there may be a weatherstripping material that works even better for your home.
Why Should I Maintain My Weatherstripping?

Maintaining your weatherstripping means these home benefits:
- Energy efficiency: Properly done weatherstripping can lower your heating and cooling bills and support a more sustainable home.
- Comfort: Effective weatherstripping prevents drafts and noise that make homes uncomfortable. Youโll also be able to consistently keep your home at your desired temperature much more easily.
- Protection: High-performing weatherstripping stops dust, pests and weather from getting into your home. Otherwise, you may have to deal with stains or even moldy areas near your doorways due to moisture.
Signs It’s Time to Replace Weatherstripping on Your Doors

You want to check your weatherstripping at least twice a year. Expert tip: Itโs best to look for the following signs right before St. Louisโ winter and summer really take off.
Visible Damage
Watch out for wear and tear in the form of cracks, disintegrated parts or warped, misshapen materials.
Drafts and Leaks
You’ll likely see any door leaks, but drafts may be hard to feel. You can check for drafts by looking at a closed door and seeing if any light comes through. You can also carefully move a lit candle or incense near a closed door and see if the smoke wavers.
Increased Energy Bills
Look out for a sudden rise in energy costs that doesnโt seem to make sense based on your year-to-year trends. Another clear sign is always fighting with your thermostat to keep your home at the temperature you want it to be.
Replacing Your Weatherstripping
The general rule of replacement for door weatherstripping is every few years. How often you use a door can impact this, so entry doors will generally require more support than patio doors or French doors.
The process for replacing weatherstripping generally involves:
- Removing any old weatherstripping by hand, with the help of a putty knife and/or by using tools to remove any nails and/or screws.
- Cleaning and drying the area where the new weatherstripping will go.
- Getting your selected type of weatherstripping to the necessary size (if youโre using foam tape, you can use a tape measure and scissors to cut it).
- Apply the weatherstripping (adhesive types can simply be peeled and stuck on, but other varieties will require screwing or nailing it into place).
Replacing weatherstripping is relatively easy, but what if new weatherstripping isnโt enough? If any of your doors are in too poor of condition, itโs time to consider a cost-efficient door replacement that will offer energy, cost and comfort benefits that new weatherstripping alone canโt.
