2026-06-02 A2Z Garage Doors
A customer called last Tuesday complaining about cold air pouring into her garage and rising heating bills. She assumed the problem was her garage door opener or the door itself. After a quick inspection, we found the culprit: worn weather stripping and a deteriorated bottom seal. The fix was simple, affordable, and solved her problem the same day. If your garage feels drafty or you see daylight around the door frame, faulty weather stripping and seals are likely the reason. This post explains what these components do, when to replace them, and how much you should budget.
Weather stripping is the flexible material that runs along the sides and top of your garage door frame. It seals gaps between the door and the opening, blocking wind, rain, dust, and pests. The bottom seal (also called a threshold seal) sits at the lowest point where the door meets the floor, creating a tight barrier when the door closes.
Both components wear out over time. UV exposure, temperature swings, and repeated opening and closing cause rubber and vinyl to crack, harden, or separate from the frame. In Lake Oswego, where winters bring rain and temperature fluctuations, this wear accelerates.
A good seal keeps your garage warmer in winter and cooler in summer. It also protects stored items from moisture and pests. When seals fail, you lose energy efficiency and invite unwanted guests into the space.
Look for these red flags. Visible cracks or gaps in the rubber or vinyl material mean it's time to act. If you see daylight coming around the frame when the door is closed, the seal isn't doing its job. Cold drafts, water stains, or pest droppings inside the garage also point to failed seals.
Run your hand along the frame on a windy day. If you feel a strong draft, the threshold or side seals are compromised. Many homeowners ignore these signs until heating costs spike, but catching the problem early saves money.
Seals typically last 5 to 7 years depending on weather and usage. If your garage door is older than that and you haven't replaced the stripping, now is the time. Check our guide on preparing your garage door for summer to learn more about seasonal maintenance that extends seal life.

Budget between $150 and $400 for a complete replacement, depending on door size and material quality. Basic vinyl stripping runs cheaper than reinforced rubber or specialized threshold seals rated for heavy use.
Labor typically accounts for half the cost. A straightforward job takes 30 to 60 minutes if there's no underlying frame damage. If the frame is rotted or misaligned, expect additional charges for repairs.
Getting an estimate before committing is smart. We offer free estimates and can often complete the work the same day. Compare this cost to what you'll spend on extra heating or cooling if you ignore the problem. A failed bottom seal can add 10 to 15 percent to your monthly energy bill during winter months.
Don't overpay by replacing seals when only the weather stripping needs attention, or vice versa. A trained technician can diagnose exactly which components need work. That's where experience saves you money.
Simple replacement of weather stripping is manageable for handy homeowners. You'll need a pry bar, new stripping material, and an afternoon. Remove the old material, clean the frame thoroughly, and press the new stripping into place.
However, bottom seals are trickier. They bolt or bolt-and-nail to the door bottom and require precise alignment. If installed incorrectly, they can interfere with the door's operation or fail prematurely. Threshold seals also need proper spacing to allow the door to close without binding.
If your door has structural issues or the frame is warped, a professional inspection is worth the investment. We can spot problems that lead to seal failure and fix them before they worsen. Learn more about our weather stripping and seal services or schedule a free quote to avoid costly mistakes.
Standard vinyl stripping works well for mild climates and light use. It's affordable but wears faster in harsh conditions. Reinforced rubber withstands temperature extremes better and lasts 7 to 10 years. Specialized high-performance seals exist for commercial doors or extreme weather zones.
For Lake Oswego homeowners, mid-range reinforced rubber offers good value. It balances durability with cost and handles our wet, cool winters without degrading quickly.
After replacement, inspect seals every spring and fall. Clean away dirt and debris that can prevent proper closure. Apply silicone-based lubricant to rubber seals annually to keep them supple.
If you've recently invested in a new garage door or upgraded your opener, proper seals protect that investment. Poor seals let moisture into the garage, which can damage cars, tools, and stored items over time.
Take weather stripping seriously. It's one of the cheapest maintenance items but delivers outsized value in comfort and energy savings.
How often should I replace garage door weather stripping in Lake Oswego? Every 5 to 7 years, depending on weather exposure and wear. If you notice visible damage, gaps, or drafts sooner, replace it immediately rather than waiting.
Can I replace weather stripping myself? Yes, for side and top stripping. Bottom seals are more complex and often require professional installation to ensure proper alignment and function.
What's the difference between weather stripping and a bottom seal? Weather stripping seals the sides and top of the door frame. The bottom seal sits at the floor and fills the gap where the door meets the ground.
Will new seals reduce my heating bill? Yes. Poor seals can add 10 to 15 percent to winter heating costs. Replacement typically pays for itself within one heating season.
Do I need to replace both stripping and seals at the same time? Not always. Have a technician inspect both. Sometimes only one component needs replacement, which lowers your cost.
