Weather Stripping & Seals in Redmond: Stop the Draft, Save the Heat

2026-06-01 7 min read

Weather stripping and seals around your garage door stop cold air, rain, and pests from entering your home. Over time, these rubber strips compress, crack, or peel away, letting drafts steal your heating and cooling. If you feel air leaking around your door frame in Redmond, replacement usually costs between $150 and $400 and takes one visit.

I've been installing and replacing weather stripping for 15 years. Most homeowners don't realize how much energy waste starts at the garage. It's the biggest uninsulated entry point on most houses. The good news: this is one of the cheapest fixes we do, and the payoff is real.

What Weather Stripping Actually Does

Your garage door has seals in three spots: the sides, the top, and the bottom. The bottom seal, sometimes called a threshold seal or bottom sweep, takes the most abuse. It flexes every time the door opens and closes. Rain pools against it. Tires roll over it. By year four or five, it's usually shot.

The side seals and top seal protect the frame itself. They keep the weather out and your conditioned air in. When these fail, you'll notice:

- Visible light coming through gaps, A draft you can feel with your hand, Water pooling inside after rain, Rodents or insects finding their way in

I've seen homeowners patch these with caulk or weatherstripping tape from the hardware store. It buys you a few months, maybe. Real replacement is the move.

Why Redmond's Climate Makes This Critical

We get rain nine months out of the year up here. That moisture sits against your door frame, garage wall, and especially that bottom seal. In Kirkland and across the Eastside, the same problem shows up constantly.

When seals fail, water wicks into wood frames and drywall. You end up with mold, rot, and structural damage that costs thousands to fix. Replacing weather stripping and seals now prevents that.

Additionally, a tight seal means your garage stays closer to outdoor temperature, but the draft you're fighting won't pull conditioned air from your house. That's where the energy savings show up on your power bill. Over a heating season, a good bottom seal and side seals can save 10 to 15 percent on garage-related heat loss.

Types of Seals and When to Replace Them

Not all weather stripping is created equal. The standard rubber bottom seal lasts 4 to 6 years. It's affordable and works well in our climate. Vinyl side seals last longer, maybe 7 to 8 years, but they can become brittle in cold.

Some homeowners ask about the heavier rubber threshold seals or the foam-backed vinyl strips. They cost a bit more upfront but hold up better to moisture and UV. If you're planning to stay in your home another decade, the upgrade is worth it.

Our team at Redmond Garage Doors assesses wear during routine maintenance. If you've had your door installed more than five years ago, seals are likely due. We'll give you a cost estimate and explain which material makes sense for your situation.

Signs Your Seals Need Replacement

The most obvious sign is visible damage: cracks, peeling, missing chunks. But there are subtler clues too.

If your garage is noticeably colder or warmer than it should be, seals are a prime suspect. You might also notice dust or dirt accumulating along the bottom of the door or the frame. That's air (and debris) finding its way through gaps.

One test I recommend: on a dry day, run your hand along the bottom of the door from the inside. Feel for air movement. Even a slight draft means the seal is compromised.

If you've noticed your garage door is stuck or hard to open, worn seals aren't the cause, but they often show up alongside other issues that need attention.

Cost and What to Expect

A bottom seal replacement runs $100 to $150. Side seals and top seals together add another $100 to $200. Labor is usually included in that range if you go with a professional. The whole job takes 30 to 45 minutes.

If you're replacing seals yourself, you'll spend $40 to $60 on materials and about two hours of your time. The tricky part is getting the old seal cleanly off without damaging the frame, then measuring and aligning the new one straight. Most people get it right the first time, but it's fussy work.

Pairing Seals with Other Upgrades

If you're replacing seals, it's a good time to think about whether your garage door opener is still efficient. A newer opener with smart features can reduce the number of cycles your door goes through, which saves energy and extends the life of your seals.

Insulated garage doors also pair well with new seals. Together, they create a real thermal barrier. That's especially valuable in Redmond, where humidity and temperature swings put stress on uninsulated doors.

Getting It Done Right

Weather stripping and seals aren't glamorous, but they're one of the best returns on investment you'll get in garage door work. You see the savings immediately. You feel the difference in comfort.

Frequently Asked Questions

How long does a garage door bottom seal last? Most rubber bottom seals last 4 to 6 years in our Pacific Northwest climate. Moisture and repeated flexing wear them out faster than in drier regions. Inspect annually after year three.

Can I replace weather stripping myself? Yes, if you're handy. The material costs $40 to $60, and installation takes two hours. The main challenge is removing old adhesive cleanly and getting the new seal perfectly straight and aligned.

What's the difference between a bottom seal and a threshold? A bottom seal (also called a sweep or gasket) is the flexible rubber strip on the garage door itself. A threshold is a rigid piece that sits on the floor. Many doors use both for maximum protection.

Will new seals reduce my energy bill? Yes, noticeably. Sealing air leaks around the garage can save 10 to 15 percent of heat loss from that space over a season. Exact savings depend on how much the door was leaking and your local utility rates.

Do I need to replace all seals at once? Not necessarily. If only the bottom seal is damaged, you can replace just that. However, if side or top seals are also worn, replacing them together ensures consistent performance and saves on service calls.
