A customer called last Tuesday morning. Her garage was cold, the electric bill had climbed $40 a month, and she could feel air moving under her garage door on windy days. We arrived within two hours, inspected the bottom seal and threshold, and found the rubber had cracked and shrunk. Weather stripping and seals stop drafts, regulate temperature, and keep pests and moisture out. This post explains what they do, why they fail in Florida's heat, and how to know when replacement is overdue.
Your garage door's weather stripping sits along the sides, top, and bottom. The bottom seal (often called a threshold or gasket) takes the most abuse. These rubber or silicone strips create an airtight barrier between your garage and the outside world.
Think of them as a gasket on a Tupperware lid. Without a tight seal, cold air escapes in winter, hot air leaks in summer, and pests find easy entry points. In Montverde, where humidity runs high and temperatures swing, that seal works overtime. A compromised seal means your HVAC system runs longer, your energy costs spike, and moisture can damage stored items or automotive equipment.
When the bottom seal fails, you'll see light under the door on a sunny day. You might notice insects, small lizards, or even spiders nesting in your garage. Sometimes the draft is subtle but costs real money over months.
Montverde sits in Central Florida's intense sun belt. Rubber and silicone seals degrade faster here than in cooler climates. UV exposure, temperature cycling (80 degrees to 95 degrees in a single day), and humidity all accelerate wear. Most seals last 3 to 5 years before they crack, harden, or lose compression.
If your garage door was installed more than four years ago and you've never replaced the seals, they're likely compromised. The cost of replacement is minimal compared to the energy waste.
Related to this, if your garage door itself is poorly insulated, weather stripping won't fully solve the problem. Our guide on garage door insulation in Montverde explains heat loss prevention in detail.

Look for these red flags. Visible cracks, splits, or hardening in the rubber mean the seal has lost its flexibility. If you press on the bottom seal and it doesn't spring back, it's time. Daylight visible under the door on a bright morning is a clear signal. You might also notice an uptick in pest activity or moisture inside the garage during heavy rain.
Another clue is energy loss. If your garage is attached to a conditioned space (like a bedroom above it), poor seals force your air conditioner to work harder. You'll feel the difference on your bill within weeks of a bad seal.

The cost varies based on seal type and your door's size. A standard bottom seal replacement runs $150 to $400 installed. Full perimeter sealing (sides, top, and bottom) typically costs $300 to $600. If your door frame is damaged or warped, the estimate might be higher.

You can buy adhesive-backed foam seals at a hardware store and install them yourself. They're inexpensive and a decent temporary fix. But they won't last as long as professional rubber or silicone seals, and poor installation leaves gaps.
Professional installation ensures proper alignment, compression, and durability. We measure your door's frame, select the right seal material for your door type, and install it so it compresses evenly. That precision adds years to the seal's life.
If you've noticed drafts, rising energy costs, or pest activity in your garage, don't wait. Bad seals compound over time. Moisture can damage your door's frame or springs, and energy waste adds up fast.

How long do weather seals last on a garage door? In Florida's heat and humidity, most rubber or silicone seals last 3 to 5 years. UV exposure and temperature swings accelerate degradation. Annual inspection helps you catch wear before drafts become a problem.
Can I replace weather stripping myself? Yes, adhesive-backed foam strips are available at hardware stores and easy to apply. However, professional rubber seals installed by a technician last longer and seal more effectively because they're compressed properly and aligned with the door frame.
What's the difference between a bottom seal and a threshold? A bottom seal (or gasket) is the rubber strip attached to the bottom of the door itself. A threshold is a fixed bar on the floor where the door sits. Both work together to close the gap and stop drafts.
Will new weather stripping reduce my energy bill? Yes, if your current seals are cracked or missing. A tight seal reduces the load on your HVAC system, especially if your garage is attached to a conditioned living space. Savings vary by climate and how much your seals were compromised.
How do I know if my seals are failing? Look for visible cracks, hardness, or light under the door. If the seal doesn't compress when you press it, or if you notice increased pest activity or moisture, replacement is overdue.
