If you've noticed cold air creeping into your garage or your heating bills climbing in fall, worn weather stripping and seals are likely the culprit. Weather stripping and seals in Everett stop drafts, regulate temperature, and protect your garage from water and pests. I've been fixing garage doors for 15 years, and I can tell you that this is one of the easiest preventive fixes homeowners skip.
Your garage door is a big moving part of your home's envelope. Most people don't think of it as insulation, but it absolutely is. The weather stripping and seals create a barrier between your garage and the outside world. When they wear out, you're essentially leaving a window open all winter.
In Everett's climate, that's not a small problem. We get cold, wet winters with salt air off the harbor. The bottom seal, also called the threshold, takes the most punishment because it rides on concrete and absorbs water from snow melt. Springs last 7 to 9 years with normal use. Seals? They typically last 3 to 5 years depending on how often the door opens and closes.
The draft you feel isn't just discomfort. It's energy waste. Cold air means your furnace works harder. Moisture seeping past worn seals can lead to rust on the door frame and damage to stored items. Plus, rodents and insects find gaps in seals an open invitation.
A complete weather stripping system has three main components: the bottom seal, the side seals, and the top seal.
The bottom seal takes the hardest hits. It compresses against the concrete threshold every time the door closes. Over time, UV exposure and repeated compression degrade the rubber. You'll notice it's failing when you see daylight under the door or feel a strong draft.
Side seals run along the left and right edges. They're typically rubber or vinyl and prevent wind and rain from entering around the sides. These wear more slowly than the bottom seal but still need checking annually.
The top seal runs across the top of the door opening where it meets the header. It's often overlooked but critical for keeping rain out. If you've had roof leaks near your garage, a failed top seal might be the reason.

A full weather stripping and seal replacement typically runs between $150 and $400 depending on your door's size and condition. The bottom seal is usually $80 to $150. Side and top seals add another $100 to $200. Labor is straightforward and often done the same day.
I always recommend getting an estimate before committing. Everett Garage Doors offers free estimates so you know exactly what you're paying before we touch anything. Some companies charge for the estimate. We don't.
Installation takes 1 to 2 hours for most residential doors. We'll remove the old seals completely, clean the channels, and install new ones with proper tension. Rushing this job is how you end up with seals that pop out after six months.
If your door is older or has had heavy use, we might recommend replacing the entire weatherstripping kit rather than patching individual seals. It's more economical long-term and ensures everything works together.
You don't always need a full replacement. Small cracks or minor compression loss can sometimes be sealed temporarily with weatherproof caulk. But that's a band-aid fix. Real seals need real replacement.
Signs you need new seals: visible gaps, cracking rubber, daylight under the door, water pooling inside after rain, or drafts you can feel from your house. If the door is hard to close or requires extra pressure, the seal might be swollen and needs replacement.

Everett sits right on the harbor. That salt air and moisture accelerate seal degradation. We see more seal failures here than in inland suburbs. The freeze-thaw cycle of New England winters also works against rubber seals. Water gets into tiny cracks, freezes, expands, and splits the seal further.
That's why I recommend checking seals every fall before the cold months hit. A $200 preventive seal replacement in October beats emergency repair in February when your garage is drafty and cold.

How long do garage door seals last? Bottom seals typically last 3 to 5 years. Side and top seals may last 5 to 7 years. Life span depends on climate, door usage frequency, and UV exposure. Everett's coastal weather shortens lifespan compared to inland areas.
Can I replace weather stripping myself? Yes, but it requires proper tools and technique. Seals must be installed with correct tension and alignment or they'll pop out. Most homeowners find professional installation worth the cost to ensure it's done right the first time.
What's the difference between a bottom seal and a threshold? The bottom seal is the rubber or vinyl strip attached to the door's bottom edge. The threshold is the concrete or metal surface it compresses against. Both work together as the seal system.
Will new seals reduce my energy bills? Yes. Sealing air leaks can reduce heating and cooling costs by 10 to 15 percent depending on your door's condition and insulation value. Combined with proper door insulation, the savings compound.
How often should I have seals inspected? We recommend annual inspection every fall. Early detection of wear prevents water damage, pest intrusion, and energy waste. Many customers schedule inspection during their pre-winter garage door maintenance.
