Weather Stripping & Seals in Harrington: Why Your Garage Door Leaks Air (And How to Fix It)
2026-08-11 5 min read
Here's what most homeowners don't realize about weather stripping and seals: they're not just comfort upgrades. A failed bottom seal or deteriorated threshold allows conditioned air to escape your home year-round, costing you real money every month. I've seen garages in Harrington lose 15 to 20 percent of their heating and cooling efficiency because of gaps nobody noticed until the utility bill arrived.
Your garage door is the largest moving entry point in your home. When weather stripping fails, drafts sneak in around the sides and bottom. Cold air spills in during winter. Hot air rushes out in summer. And if you use your garage as a workspace or finished room, that draft becomes unbearable fast.
Why Weather Stripping Fails in Harrington's Climate
Our region sees temperature swings, moisture, and UV exposure that break down seals. Rubber and foam degrade over time. Most weather stripping lasts 3 to 5 years before needing replacement. That timeline varies based on sun exposure, humidity levels, and how often you cycle the door open and closed.
Harrington winters pull moisture into the garage. That moisture creeps under poor seals and can damage your walls, insulation, and stored items. I've worked on doors where mold developed inside the wall cavity because water kept finding its way past a cracked bottom seal. By then, the cost to fix the underlying damage far exceeded the cost of preventive sealing.
The threshold area takes the worst beating. It sits directly on the ground where debris, water, and temperature swings concentrate. If your bottom seal has cracking, peeling, or visible gaps larger than a quarter-inch, replacement is overdue.
Types of Weather Stripping & Seals for Garage Doors
Your garage door uses several sealing components working together. The bottom seal (or astragal) runs the full width at the door's base. Side seals mount vertically along both sides. The top seal caps the header. Each serves a specific purpose, and all must be in good condition.
Rubber seals are durable and flexible, handling temperature changes well. Foam seals are affordable but compress faster under pressure. Some homes benefit from a combination approach, using rubber where traffic is heavy and foam in protected areas.
When you contact us at Harrington Garage Doors for an estimate, we evaluate which seals are failing and recommend the right replacement material for your door type and climate exposure. There's no one-size-fits-all answer, which is why a proper inspection matters.

Cost, Timeline, and DIY Traps
A full weather stripping and seals replacement typically costs between $200 and $600 depending on door size and seal quality. That's far less than the energy waste from a drafty door over even one winter season. Most jobs take 1 to 2 hours. We often schedule same-day appointments for residents who call early in the day.
DIY replacement is possible, but I've seen more failures from homeowner attempts than successes. Seals must be trimmed precisely, adhesive applied evenly, and fasteners installed without over-tightening (which pinches the seal and reduces its effectiveness). Misaligned seals create worse drafts than worn ones. If you're not comfortable with the work, hiring a professional saves frustration and ensures the job holds.
If you're already planning other garage door work, bundle sealing with it. You'll save on labor and ensure all components work together. For example, if you're replacing springs or an opener, ask about including new weather stripping. We detail pricing and timelines in our garage door cost breakdown for Harrington homeowners.
Signs You Need New Seals Now
Visible cracks, peeling edges, or hardened rubber are clear signals. But also watch for light visible under the door when it's closed. Any draft you can feel with your hand means air is escaping. In winter, ice forming along the bottom edge indicates moisture and air leaks meeting cold outside temperatures.
If you've had your door for 10 years or longer and never replaced seals, they need attention regardless of appearance. Weathering happens invisibly.

Frequently Asked Questions
How long do garage door seals typically last? Most weather stripping and seals last 3 to 5 years depending on climate exposure and door usage frequency. Harrington's moisture and temperature swings accelerate wear compared to drier regions.
Can I replace just the bottom seal, or do I need all seals replaced? You can replace individual seals as they fail. However, if side and top seals are close to end of life, replacing everything at once saves labor costs and ensures consistent performance across the door.
Will new weather stripping reduce my heating bill? Yes. A properly sealed garage door reduces energy loss by 15 to 20 percent. Over a winter season in Harrington, that translates to measurable savings, especially if your garage is attached to your home.
What's the difference between foam and rubber seals? Rubber seals are more durable and handle temperature swings better, lasting longer under repeated compression. Foam is more affordable but compresses faster and may need earlier replacement in high-traffic garages.
Should I replace weather stripping before or after winter? Fall is ideal for Harrington homes. Replacing before cold weather arrives ensures maximum efficiency throughout winter and prevents moisture problems. Spring replacement works too if you missed the season.
