Garage door weather sealing is one of the best ways to protect your home each spring. Spring in Houston means warmer days, blooming trees, and the return of strong storm systems moving in off the Gulf. Between March and May, wind-driven rain and sudden downpours are common, and your garage door is one of the largest openings in your home’s exterior. Taking a little time now to weatherproof your garage door can save you from water damage, drafts, and unwanted humidity later in the season. A little preventive attention now goes a long way once the season’s first real downpour arrives.
Why Spring Storms Are Tough on Garage Doors
Houston’s spring storms often bring gusty, sideways rain rather than a steady straight-down shower, which means water can be pushed underneath and around a garage door that isn’t properly sealed. Over time, gaps in the weatherstripping let in water, dust, and even small pests, and repeated exposure can warp wooden doors or cause rust on metal hardware. Attached garages are especially vulnerable, since water that gets past the door can travel into a laundry room, workshop, or storage area and cause damage well beyond the garage itself.
Weather-Sealing Checklist
- Check the bottom seal (astragal) for cracks, gaps, or flattening, and replace it if water is getting through.
- Inspect side and top weatherstripping for brittleness or separation from the frame.
- Look for daylight gaps around the edges of the closed door, which usually signal a sealing or alignment issue.
- Clear debris from the track so the door closes fully and seals evenly.
- Consider a threshold seal on the garage floor for extra protection against wind-driven rain.
When Weatherstripping Isn’t Enough
If your garage regularly floods along the bottom edge or the door itself has started to warp or rust, sealing alone may not solve the problem. In those cases, it may be time to talk about a replacement. We design and build custom wood and composite garage doors that can be finished with weather-resistant materials suited to Houston’s humidity and storm patterns, so you’re not stuck repeating the same repair every spring.
Timing Your Repairs Before the Season Ramps Up
The best time to schedule garage door weather sealing is before the first big spring storm hits, not after. Once heavy rain and wind arrive, technicians in Houston tend to book up quickly, and a door that’s already leaking is more likely to have hidden issues with the track, hardware, or framing underneath. A quick inspection in late winter or early spring gives us time to order any parts that aren’t in stock and get everything sealed up while the weather is still mild. It’s a small step that can prevent a much bigger repair bill down the road.
Frequently Asked Questions
How often should I check my garage door’s weatherstripping?
A quick visual check twice a year, ideally before spring storm season and before winter, is enough to catch most issues before they cause damage.
Can I replace garage door weatherstripping myself?
Basic weatherstripping replacement is a manageable DIY project for many homeowners. If your door is misaligned or the track is damaged, though, it’s best to have a technician take a look first.
Will a new garage door actually stop water intrusion?
A properly installed, well-sealed door dramatically reduces water intrusion compared to an older, worn-out door, though a threshold seal is still recommended in low-lying driveways.
