Weatherstripping and Older Homes in Spindale: A Practical Guide
2026-04-04 6 min read
Walk through almost any neighborhood in Spindale and you'll notice the housing stock skews older. The median construction year for homes here is around 1958, and a good chunk of the housing was built even earlier than that. much of it tied to the textile mill era that shaped this town's identity. These are solid, well-built homes in many cases, but older construction means older garage doors, and older garage doors almost always mean weatherstripping that has long since stopped doing its job.
If your garage door seals were installed more than five or six years ago and haven't been touched since, there's a reasonable chance you're losing conditioned air, letting in moisture from Spindale's frequent rains, and giving pests a welcome-mat-sized opening. all without realizing it.
What Weatherstripping Actually Does
Weatherstripping is the collective term for the rubber or vinyl seals that run along the bottom, sides, and top of your garage door. Together, these seals create a barrier between the interior of your garage and whatever's happening outside. When they're working properly, they block drafts in winter, keep out rain during summer storms, and reduce the amount of humidity that enters your garage on those muggy Spindale afternoons.
When they fail. and they do fail, especially in climates with wide temperature swings and consistent moisture. the effects are more significant than most homeowners expect. Even a small gap allows air to move freely in and out, which means your HVAC system works harder to compensate if your garage is attached to your home. Puddles inside the garage after a heavy rain, musty smells, and a noticeable draft near the door are all signs the seals have given out.
It's also worth knowing that good weatherstripping and good insulation are different things that work together. If you're thinking about insulation value, our post on R-value and what it means for your garage door is worth a read. but understand that even a highly insulated door performs poorly if the seals around it are failing.
The Four Types of Seals on Your Door
Bottom Seal
This is the rubber strip that presses against the floor when the door closes. It takes the most abuse. constant contact with the ground, exposure to water runoff, and compression every single time the door shuts. For homes in Forest City, Bostic, or Spindale where the garage floor may have slight irregularities from settling over the decades, the bottom seal is especially prone to uneven wear.
Side Seals (Jamb Seals)
These run vertically along the left and right edges of the door, pressing against the door frame when closed. They're easier to overlook because they're less visible, but a gap here lets cold winter air. and Spindale winters can push down toward 29°F. flow right along the wall of your garage.
Top Seal (Header Seal)
Not every residential garage door has one, but a header seal across the top of the door is particularly useful if your garage is used as a workshop or if there's a finished room above it. It also helps prevent the slight bowing that happens when one side of the door is significantly warmer than the other, which is common in summer when the exterior surface heats up.
Between-Panel Seals
These small rubber inserts sit between the horizontal sections of a sectional door. On older doors, these are often the first to crack and harden, creating gaps you can actually see light through when the door is closed.
How to Check Your Seals Without Any Special Tools
You don't need anything fancy for this inspection. just your eyes and hands.
1. Close the door and go inside the garage. On a bright day, look at the bottom and sides of the door from the inside. Any points where you can see daylight are gaps that need to be addressed. 2. Feel for drafts. Run your hand slowly along the bottom seal and both side seals. Even subtle air movement indicates a compromised seal. 3. Press the bottom seal. It should feel pliable and spring back when you release it. If it's stiff, cracked, or crumbles slightly, it's time to replace it. 4. Look for discoloration or water marks. Staining on the garage floor near the door's edge is a reliable sign that water has been getting in regularly.
If you find more than one of these issues, it's worth having a professional assess the full condition of the seals and the door itself. Spindale Garage Doors can take a look and tell you exactly what needs replacing versus what can wait. Reach out to schedule a visit.
The Energy and Cost Case for Replacing Seals
One of the things homeowners in this area sometimes underestimate is how much a compromised garage door seal affects their energy bill. especially in homes where the garage shares a wall with the living space. Cold drafts in January don't just make the garage uncomfortable; they bleed into the adjacent room and force your heating system to work harder.
Replacing weatherstripping is one of the most cost-effective maintenance tasks you can do. The materials themselves are inexpensive, and when a professional handles the installation, the seals are fitted correctly and last longer than a DIY job on an uneven older floor.

Frequently Asked Questions
How often should weatherstripping be replaced on a garage door? For most homes in Spindale's climate, plan on inspecting seals every year and replacing them every five to seven years. Doors that see heavy use, or that are exposed to direct sun on the south-facing side of the house, may need replacement sooner since UV exposure hardens rubber seals faster.
Can I replace the bottom seal myself? The bottom seal is the most DIY-friendly of the four seal types. If your door has a standard retainer track, you can slide in a new rubber strip without special tools. That said, if the retainer itself is damaged or the floor is uneven. common in older Spindale homes. a professional can ensure the fit is proper and the seal actually makes full contact with the floor.
My garage door is drafty in winter but the seals look okay. What else could cause this? If the seals look intact but you're still feeling drafts, check the between-panel seals on your sectional door. these small inserts are easy to miss but harden and crack with age. Also check that the door itself is hanging level. A door that's even slightly out of alignment won't press evenly against any of its seals, leaving gaps regardless of how new the weatherstripping is.
