Most people don't think about their garage door until something breaks. But long before your opener fails or a spring snaps, your weather stripping and seals are quietly losing you money. A worn bottom seal or deteriorated threshold doesn't just let cold air in. It invites pests, moisture, and higher energy bills into spaces you're paying to heat or cool.
I've walked into Monmouth garages in January where the owners had no idea their bottom seal had cracked months earlier. By then, spiders had colonized the rafters, and the concrete was stained with water damage. The cost to fix? Thousands. The cost to replace the seals beforehand? Less than $200. See our guide: Snapped Garage Door Springs in Monmouth.
Your garage door is not just a barrier for your car. It's part of your home's thermal envelope. When weather stripping deteriorates, the draft that sneaks through doesn't just affect your garage. It affects your utility bills, your comfort, and the lifespan of everything stored inside.
A compromised bottom seal creates gaps where outside air rushes in. In winter across Oregon, that means cold seeping into spaces attached to your home. If your garage shares a wall with a bedroom or living area, that draft travels through studs and insulation. Your HVAC system works harder. Your heating costs rise 10 to 15 percent in some homes.

Seals and weather stripping also protect against water intrusion. During Monmouth's rainy season, a bad threshold allows water to pool under your door. Concrete cracks. Metal rusts. Wood rots. Mold follows. These aren't cosmetic problems. They're structural and health concerns that compound fast.
Look for these specific warning signs before winter arrives.
Visible gaps or cracks in the rubber or foam. Run your hand along the bottom seal and sides. Feel for roughness, brittleness, or separation from the frame. Rubber weather stripping typically lasts 5 to 7 years before UV and temperature swings make it brittle.
Cold air flowing under the door. On a calm day, light a candle near the bottom seal from inside the garage. If the flame flickers, you have a draft. That means conditioned air is escaping and outside air is creeping in.
Water pooling after rain. The threshold is the metal or composite strip at the base. If water sits there instead of running away, your seal isn't doing its job. This leads to concrete deterioration and rust on metal tracks.
Visible daylight around the door frame. Close the door and look from inside. Do you see light along the sides or top? That's a sign seals have shrunk or come loose.
Pest activity. Insects and rodents find their way through tiny gaps. If you notice cobwebs, droppings, or pest entry points near your garage door, a worn seal is often the culprit.

The cost to replace weather stripping and seals is one of the best values in garage door maintenance. A bottom seal replacement typically runs $100 to $250, depending on your door size and material. Side seals add another $50 to $100 each. A complete threshold replacement (the metal or composite strip at the base) ranges from $150 to $300.
These are estimates and real prices vary. The key insight: catching this work early is far cheaper than repairing water damage, replacing concrete, or dealing with a pest infestation later.
If you're also noticing issues with your opener or springs, consider bundling the work. When snapped garage door springs need repair, seals often need attention too. And if you're planning any major work, a full tune-up makes sense.
Once new seals are installed, protect them. Keep your garage door clean and free of debris that can jam the bottom seal. Don't park or store items directly against the door. And inspect seals every spring and fall, especially in Oregon's climate where temperature swings and moisture are constant.
If you use your garage as a workshop or storage space, monitor humidity. High moisture accelerates seal degradation. A simple dehumidifier or better ventilation extends seal life significantly.
The bottom line: weather stripping and seals are cheap insurance. Replace them before they fail, and you avoid water damage, pest problems, and energy waste. Schedule a free quote today to have our team inspect your door, or call (541) 658-3701 for a same-day estimate.
Don't wait until January to discover your seals are shot. Winter is coming, and your wallet will thank you for acting now.
How often should I replace weather stripping? Most weather stripping lasts 5 to 7 years depending on climate and sun exposure. Oregon's wet winters and temperature fluctuations accelerate wear. Inspect annually and replace when you see cracks, brittleness, or gaps.
Can I replace weather stripping myself? Minor caulking or adhesive-backed foam strips are DIY-friendly. Full bottom seal or threshold replacement requires precision and tools. Improper installation leaves gaps that defeat the purpose. Professional installation ensures proper fit and durability.
What's the difference between a bottom seal and a threshold? The bottom seal is the rubber or foam that attaches to the door itself. The threshold is the metal or composite strip mounted to the ground or frame. Both work together to block drafts, water, and pests.
Does bad weather stripping really affect my energy bills? Yes. A compromised seal allows heated or cooled air to escape. Studies show poor garage door seals can increase heating costs by 10 to 15 percent, especially in attached garages. Replacement pays for itself within one to two seasons.
Should I replace seals before or after winter? Before. Late fall is ideal so new seals face the full winter season intact. If you notice problems in winter, call for emergency service. Waiting until spring guarantees months of energy loss and potential water damage.
