A customer called last Tuesday. Her heating bill had jumped 30 percent since October, and cold air was leaking around her garage door. She assumed a full door replacement was coming. Instead, she needed weather stripping and seals. One afternoon and under $400 later, problem solved. This story plays out monthly here in Shedd.
Most homeowners don't realize that worn weather stripping is one of the cheapest fixes with one of the biggest payoffs. Your garage connects directly to your home. A leaky bottom seal or deteriorated threshold means your furnace is heating the outdoors while you pay for it.
Our region's moisture is relentless. Rain, fog, and temperature swings work together to break down rubber and foam seals faster than in drier climates. Most weather stripping lasts 5 to 7 years before it cracks, hardens, or peels away from the frame.
You'll notice this first as a draft. Cold air sneaks in around the sides or bottom of your door. In winter, that draft becomes an energy leak. In summer, it lets humid air inside, which stresses your cooling system and can encourage mold growth in the garage.
The longer you ignore it, the more you pay. A homeowner delaying seal replacement by two years might spend an extra $300 to $600 on heating costs alone. Then add potential moisture damage to stored items or the garage structure itself.
Your garage door has multiple seal points. The bottom seal, or threshold, is the most critical. It takes the most abuse from ground contact, debris, and temperature cycling. Side seals and top seals prevent draft from entering along the frame edges.
Rubber seals are the standard. They're affordable, reliable, and last longer than foam in our wet climate. Foam is cheaper upfront but deteriorates faster when exposed to moisture. Some premium options use silicone or vinyl compounds, which cost more but resist rot better.
The cost typically ranges from $150 to $400 for materials and labor, depending on seal type and how many points need replacement. A simple bottom seal replacement might run $200. If all four sides plus the top need work, expect $350 to $500.
This is where knowing what you actually need matters. Some companies will recommend replacing everything at once. That's not always wrong, but it's worth getting an estimate before committing. A professional inspection takes 15 minutes and costs nothing.

You can buy weather stripping kits online for $30 to $80. Some homeowners succeed installing them. Most don't, or they do but the seal fails within a year because the surface wasn't properly cleaned or the adhesive wasn't right for their door model.
The problem is prep work. Dirt, old adhesive residue, and uneven surfaces prevent new seals from sealing. Professionals spend more time on cleaning than on installation. That's what you're actually paying for.
If your door is still under warranty or if you've had previous repairs, installing your own seal can void coverage. It's not worth the savings.
A professional can also diagnose other problems while they're there. A misaligned door or bent frame might be causing your draft, not just worn seals. Learn what to troubleshoot before calling, but let an expert confirm the real culprit.
Seals typically aren't repaired. They're replaced. Patching a seal is temporary and won't save you money long term.
However, if only one small section is damaged and the rest is intact, a patch might buy you time. More often, when one seal is failing, others aren't far behind. Budget for full replacement.
Spring is the smart time. You're not losing heat in summer, and you'll be ready before cold weather arrives. But if it's July and you have a draft, don't wait. Your heating system will waste money all winter.
Winter emergencies happen too. If your seal fails mid-January, learn about same-day repair options so you're not shivering for days.
Once new seals are installed, they need minimal care. Clean the bottom seal annually to remove dirt and debris. Check for cracks or peeling every spring. If you spot damage early, you can plan a replacement rather than rush into an emergency call.
Proper garage door maintenance includes weather seal inspection. It's one line item on a homeowner's checklist that actually prevents bigger problems.
Your garage door works year-round. Protecting it with fresh seals is like changing your car's oil. Small cost, big protection.

How much does weather stripping cost in Shedd? Most bottom seal and threshold replacements run $200 to $400, including labor. Full four-side sealing costs $350 to $500. Prices vary based on seal type and your door's condition. We offer free estimates with no obligation.
Can I replace weather stripping myself? It's possible, but professionals get better results because they properly clean and prep the surface. DIY seals often fail within a year. If your door is under warranty, self-installation may void coverage.
How long do garage door seals last? Rubber seals typically last 5 to 7 years in the Willamette Valley's wet climate. Foam deteriorates faster. Silicone or vinyl compounds last longer but cost more upfront. Regular cleaning extends life.
What's the difference between a bottom seal and a threshold? The bottom seal is the rubber strip attached to the door itself. The threshold is the seal embedded in or attached to the ground. Both prevent drafts and water entry. Both often need replacement at the same time.
Will new weather stripping reduce my heating bill? Yes. A leaky garage door can increase heating costs 15 to 30 percent during winter. Fresh seals typically save $200 to $400 annually in most Shedd homes, depending on usage and climate control habits.
