If you've noticed cold air seeping into your garage or water pooling near your garage door after rain, worn weather stripping and seals are likely the culprit. These rubber components wear out over time and cost far less to replace than the energy bills and damage that follow. At Garage Door Spanaway, we see this problem constantly in our rainy climate.and it's one of the easiest fixes to get right.
Our Pacific Northwest winters are wet and cold. A faulty bottom seal or worn threshold doesn't just let in a draft.it invites moisture, pests, and mold into your garage. Over time, water damage spreads to your door frame, opener, and even into your home's foundation.
Weather stripping and seals do three critical jobs: they block drafts, prevent water intrusion, and reduce noise. When these components fail, your heating system works overtime. Studies show that poor garage insulation can increase home energy costs by 10,15% during winter months.
The good news? Replacing weather stripping is affordable and doesn't require major work.
Look for these red flags around your garage door:
Visible cracks or gaps in the rubber seal itself. If you can see daylight around the edges when the door is closed, replacement is overdue.
Water pooling inside the garage after rain, especially near the bottom corners. This points to a failed threshold or bottom seal.
Drafts and temperature swings in your garage. On a cold Spanaway morning, your garage shouldn't feel like the outdoors.
Pest droppings or insects entering through gaps. Rodents and spiders exploit even small openings.
Hardened or cracked rubber that no longer compresses when you push on it. Rubber degrades after 5,7 years of weather exposure.
Most homeowners don't think about these seals until something goes wrong. By then, the cost of water damage repair far exceeds the cost of preventive maintenance.

Not all seals are created equal. Understanding the options helps you make an informed choice.
Bottom seal (or threshold seal) runs along the bottom of your door and takes the most abuse. It flexes each time the door opens and closes, and it bears the brunt of rain and debris. Expect to replace this every 5,7 years.
Side seals line the vertical edges of your door frame. These prevent drafts and water from entering along the sides.
Top seal runs across the top of the door. It's less exposed than the bottom but still important for a complete weather barrier.
Header seal sits in the frame above the door and protects against water running down from above.
Each type comes in standard rubber, reinforced rubber, or silicone. Silicone lasts longer and resists UV better, but costs more upfront. We're transparent about pricing on all options.no hidden markups. If you're curious about the actual cost before scheduling, check out our garage door opener pricing guide, where we break down real numbers.
Some homeowners tackle this themselves. If you're mechanically inclined and your door is older, it's possible. You'll need a screwdriver, the correct replacement seal (order by your door's model number), and about an hour.
However, professional installation ensures the seal sits flush and compresses evenly. A seal that's crooked or compressed unevenly won't block drafts or water effectively. That's where we come in. Our technicians measure, fit, and test every seal before we leave your driveway.
