Here's what most homeowners don't realize about weather stripping and seals: they fail quietly. Your garage door can look fine while cold air pours through gaps around the frame, between panels, and especially along the bottom seal. By the time you notice the draft, you're already losing heated air and paying more to warm your home. The fix is straightforward, but timing matters.
Weather stripping and seals exist for one job: blocking weather. They're not glamorous. They won't make your garage door open faster or smarter. But they'll save you money, protect your car and belongings, and keep pests and moisture out of your garage. In Malo's climate, where winters get serious, a failing threshold seal turns your garage into a wind tunnel.
The bottom seal takes the most punishment. Every time your door opens and closes, it flexes, compresses, and ages. Over time, rubber hardens. Cracks develop. Water pools underneath instead of draining away. If you see daylight under your closed door or feel a breeze, your bottom seal is done.
The side seals matter just as much. These run vertically along each side of your garage door opening. They're easy to overlook because they sit out of sight. But they're responsible for keeping wind and rain from entering at the jamb. The threshold, that horizontal strip at the base, works with the bottom seal to create a weathertight barrier.
One more place fails regularly: the header seal at the top of the opening. Cold air sinks, but so does rain. If water gets past the header, it can damage your door frame and allow drafts to sneak in from above.

You can buy adhesive-backed foam strips and install them yourself. They're cheap. They're quick. And they stop working within a season or two. Here's why: foam expands and contracts with temperature swings. In Malo, you'll see 40 to 50 degree shifts between day and night in fall. That movement loosens adhesive and breaks the seal.
Real weather stripping uses bulb seals or silicone-based materials that stay flexible over decades, not months. The bottom seal on your garage door isn't just a foam strip. It's a specially engineered rubber product designed to compress against the concrete slab while still sealing tightly against the door.
Installation matters more than material. A professional measures the threshold accurately, cleans the surface properly, and ensures the seal sits flush against the door panel. Gaps of just 1/8 inch defeat the whole purpose. If you're seeing drafts or high heating costs, reach out for a free estimate so we can inspect your current seals.
A draft around your garage door pulls warm air from your home nonstop. If your garage connects to your house, that's a direct path into conditioned space. A single gap the size of a pencil line can waste as much energy as leaving a window cracked open all winter.
Beyond energy, water gets inside. Concrete stains. Metal rusts. Items stored in the garage suffer. Pests find their way in through gaps. In a Spokane region winter, you might also deal with ice buildup around the threshold, which creates safety hazards and keeps the door from closing properly.
Our guide on garage door insulation covers the bigger picture, but seals are the foundation. A well-insulated door with failing seals is like insulating your walls but leaving the windows open.
When Malo Garage Doors inspects your seals, we check five points: the bottom seal, both side seals, the header seal, and the threshold condition. We note any visible cracks, gaps, or compression loss. We'll give you a clear cost estimate upfront and explain exactly what's wrong and why it matters.
Most jobs take a few hours. We'll remove the old seal carefully (some are glued, some are screwed in place), clean the mounting surface, and install a heavy-duty replacement seal. Same-day completion is standard for most homes in Malo. You'll notice the difference immediately: less noise, no draft, better temperature control.
If your door has other issues, we'll spot them. Worn springs, misaligned panels, or opener problems often show up during seal inspections. Check our full service list to see what we handle.
Don't wait until winter arrives. Seal replacement is most efficient in fall, before cold weather locks in. Gaps expand when it gets cold, making the problem worse. If you've noticed higher heating bills, feel air movement near your garage, or see water stains around the door frame, schedule an inspection now.
Call Malo Garage Doors at (509) 553-0761 to get a same-day estimate. We'll assess your seals and let you know exactly what you need. Small repairs now prevent larger damage and higher bills later.
Weather stripping and seals are maintenance, not an emergency. But they're also not something to ignore. Take care of them, and they'll take care of you.
How long do garage door seals typically last? Quality rubber seals last 7 to 10 years with normal use. Cheap foam strips fail in 1 to 2 years. Climate, door frequency, and UV exposure all affect lifespan. Inspect annually and replace when you see cracks or compression loss.
Can I replace just the bottom seal, or do all seals need replacing? You can replace individual seals, but we often recommend doing them together. If the bottom seal failed, side seals are usually close behind. Replacing all at once costs more upfront but saves labor and ensures consistent protection.
Will new seals reduce heating costs? Yes, noticeably. A single large gap can cost 10 to 15 dollars per month in wasted heating. Proper seals cut that waste entirely. Combined with insulation, seals deliver measurable savings over the heating season.
What's the difference between a threshold and a bottom seal? The threshold is the horizontal structure at the base of your opening. The bottom seal is the rubber strip attached to your door that compresses against the threshold. Both work together. A damaged threshold might require concrete repair, not just seal replacement.
Do I need weather stripping if my door is insulated? Absolutely. Insulation slows heat transfer through the door panel. Seals block air leakage around the edges. Both are essential for a truly weathertight garage. Insulation without seals is only half the solution.
