A customer called last Tuesday morning. Her garage was frigid, energy bills were climbing, and she'd noticed a draft creeping under the door each night. Within minutes of our inspection, we found the culprit: a deteriorated bottom seal that had cracked and separated from the frame. This is exactly the kind of problem that sneaks up on Cougar homeowners during fall and winter, but it's entirely preventable with attention and timely maintenance.
Weather stripping and seals are your garage door's first line of defense against drafts, moisture, pests, and energy loss. When they fail, you're not just losing comfort. You're bleeding money through your heating system, inviting rodents and water damage, and risking rust on critical metal components. The good news? This is one of the most cost-effective repairs you can make. See our guide on garage door cost & pricing in cougar: what homeowners actually pay.
Our region experiences wet winters and temperature swings that punish rubber and foam seals. UV exposure, freeze-thaw cycles, and moisture saturation cause seals to harden, shrink, and crack. A threshold seal that worked fine in September may be useless by January.
Most homeowners assume their seals will last as long as the door itself. They won't. Rubber and vinyl seals typically need replacement every 5 to 7 years, even with proper maintenance. If your door is older than that and you haven't touched the seals, they're almost certainly compromised. Read about garage door spring failure warning signs in cougar: what to catch early.
I've seen weather stripping failures lead to bigger problems. Water seeping past a failed threshold can pool on the concrete floor and eventually work into the foundation. Cold air bypassing seals forces your heating system to compensate, adding 15 to 25 percent to winter energy costs. Gaps also invite insects and small animals into your garage, creating infestations that spread to the house.
Your garage door has seals running along all four sides. The bottom seal (or threshold) takes the most abuse because it bears weight, flexes constantly, and sits directly in standing water. Side seals matter too, but they degrade more slowly.
The bottom seal is a rubber or vinyl extrusion attached to the bottom edge of the door panel. Over time, the material becomes brittle, the fasteners loosen, and gaps form. A visual inspection takes seconds: look for visible cracks, separation from the frame, or hardened material that doesn't flex when you press it.
Side seals run vertically along the left and right edges inside the frame. They prevent horizontal drafts and keep debris out. They fail less dramatically than bottom seals, but a failing side seal will still let cold air pour in and raise your heating costs measurably.

A bottom seal replacement typically costs between $150 and $300 for materials and labor, depending on door type and condition. Full weather stripping with all four seals runs $300 to $600. This is honestly cheap insurance against the far larger costs of water damage, foundation issues, or heating system overwork.
Our team at Garage Door Cougar offers free estimates over the phone. We ask about draft location, door age, and visible damage, then give you a ballpark before we ever visit. If you want exact numbers, a technician can arrive same-day in most cases and assess the full threshold and draft situation in person.
Many homeowners delay this work because they think it's complex. It's not. A technician removes the old seal (a 10-minute job), cleans the frame, and installs new weather stripping. You're not replacing springs or springs components. This is straightforward preventive maintenance that pays for itself in one heating season.
Compare this to the cost breakdown in our garage door cost and pricing guide for Cougar. Weather seal work is one of the few repairs that sits in the "do it now" category.
Fall is the ideal time. Before temperatures drop, examine your bottom seal and side seals. Look for cracks, hardness, or visible separation. Feel for drafts with your hand near the frame on a windy day. If you feel cold air or see daylight through gaps, your seals have failed.
Winter repairs are more urgent because you're losing heat daily. Spring replacement makes sense too, especially if you notice pest activity or water pooling after rain. Don't wait until summer; seals that fail in winter often need immediate attention to prevent foundation seeping.
