If your garage feels drafty or you've noticed water pooling near the door after rain, your weather stripping and bottom seal are probably failing. The good news: replacing them costs far less than the energy waste they cause, and it's one of the smartest preventative moves Beaverton homeowners can make.
Weather stripping is the rubber or vinyl material that runs along the sides and top of your garage door. The bottom seal, also called a threshold seal, is the horizontal strip at the base. Together, they create a barrier against cold drafts, moisture, pests, and debris.
In the Pacific Northwest's wet climate, these seals take a beating. Constant rain exposure, temperature swings, and UV damage degrade rubber over time. Most quality seals last 3 to 5 years before they start shrinking, cracking, or peeling away from the frame.
The cost of ignoring this? Heating and cooling loss adds up fast. Studies show a compromised seal can account for 10 to 15 percent of your garage's thermal leakage. Over a winter, that means real money leaving your wallet.
Look for these red flags:
Visible gaps between the door and frame. Hold a piece of paper against the seal while closing the door. If it pulls through easily, the seal is too loose.
Water or ice buildup around the threshold after rain or freezing temperatures. This signals the bottom seal isn't doing its job.
Daylight visible under the door or along the sides. This is a draft highway.
Cracked, hardened, or missing rubber. Age shows quickly in Beaverton's wet winters.
Pest entry or unexpected insects in the garage. A failing seal invites unwanted visitors.

Quality weather stripping typically runs between $150 and $400 for labor and materials, depending on your door size and seal type. A basic bottom seal alone costs $100 to $250 installed. This is genuinely budget-friendly compared to the energy waste over a season.
Many homeowners delay because they assume it requires scheduling weeks out. Not true. Garage Door Beaverton offers same-day estimates and can often complete the work the same day you call.

You can buy weather stripping kits at hardware stores for $30 to $80 and install them yourself. If your door is older or the frame is bent, misalignment will make DIY ineffective. The seal won't seat properly, and you'll still have drafts.
Professional installation ensures proper fit and compression. Technicians measure the frame, identify any alignment issues, and use commercial-grade materials rated for longer durability. It's the difference between a temporary patch and a real fix.
If your garage door has other issues like a stuck panel or opener problems, a pro can spot those during the seal replacement. Check out our post on common garage door problems and when to call a pro for more context.
Fall is the ideal window to replace seals before winter rains and cold arrive. Spring is your second-best option, after winter has done its damage but before summer heat stresses the door further.
Don't wait until January when your heating bill spikes. Seals are inexpensive insurance against much larger repair costs down the road.
When you schedule a free quote, a technician will assess your current seal condition, check door alignment, and recommend the right seal type for your door model. You'll get a clear cost estimate before work begins. No surprises.
Installation typically takes 30 to 60 minutes. The door remains functional throughout, and you'll feel the difference immediately. Cold air stops coming through, and your garage stays quieter too.
Once new seals are in place, basic maintenance keeps them working longer. Clean the frame and seal tracks quarterly, removing dirt and debris. Lubricate moving parts lightly with silicone spray (not oil, which attracts dirt). Inspect seals each fall, especially after heavy rain seasons.
If insulation is also on your mind, our earlier post exploring garage door insulation costs and benefits pairs perfectly with seal upgrades for maximum energy efficiency.
The bottom line: Weather stripping and seals are small investments with measurable returns. Stop the draft. Stop the water. Stop wasting money on heating a garage that's open to the elements.

How do I know if my bottom seal is failing? Water pools near the door after rain, ice builds up in winter, or you see visible gaps and cracks in the rubber. A failing seal won't keep out moisture or drafts.
Can I replace weather stripping myself? Yes, if the frame is straight and undamaged. However, misalignment makes DIY seals ineffective. Professional installation ensures proper compression and durability.
How long do new seals last? Quality commercial-grade seals last 4 to 6 years in Beaverton's wet climate. Cheaper hardware store kits may degrade in 2 to 3 years.
Will new seals reduce my heating bill? Yes, noticeably. A sealed garage door stops 10 to 15 percent of thermal leakage. Savings vary based on climate and usage but typically pay for the service within one heating season.
Do I need to replace both top and bottom seals at once? Not always. If only the bottom seal shows wear, you can replace it alone. However, replacing all seals together ensures consistent performance and simplifies future maintenance.
