Weather Stripping & Seals in Cortez: Stop Drafts Before They Cost You
2026-08-07 7 min read
If you've ever felt a cold draft sneaking under your garage door on a winter night, or noticed your AC bill climbing in summer, worn weather stripping is likely the culprit. A failing bottom seal and threshold let conditioned air escape, invite moisture and pests, and force your HVAC system to work harder than it should. The fix is straightforward, affordable, and something we handle routinely here in Cortez.
What Weather Stripping Actually Does
Your garage door's seals serve three critical jobs. They block drafts that steal heating and cooling. They keep water out during Florida's intense rain and humidity. They prevent insects, rodents, and debris from entering your garage space. See our guide on how to choose the right garage door for your home.
Most homeowners don't realize their weather stripping degrades on a predictable timeline. UV exposure, temperature swings, and repeated door cycles harden and crack the rubber. In Cortez's subtropical climate, this happens faster than in northern states. A seal that might last 10 years elsewhere lasts 6 to 8 years here.
The bottom seal takes the most punishment because it bears the door's weight and contacts the threshold repeatedly. It's the first thing to fail, and ignoring it compounds the problem. Water pools behind a bad bottom seal. Mold grows. The draft worsens.
Signs Your Seals Need Replacement
Look for visible cracks, splits, or hardening along the rubber gasket. If you can see daylight between the door and frame when it's closed, that's a red flag. Feel along the bottom seal with your hand. If it crumbles or peels away easily, replacement is overdue.
Another indicator is inconsistent temperature in your garage. If one corner feels noticeably colder or warmer, the seal may be compromised in that spot. You might also notice unexpected pest activity or water stains on the garage floor after rain.
Moisture issues often announce themselves first. Condensation on windows, musty odors, or visible mold growth all point back to failing weather stripping. These problems compound quickly in Florida humidity, so addressing them early prevents costlier damage to insulation, framing, or stored items.

Types of Seals and What They Cost
The bottom seal, or threshold gasket, is the most common replacement. Basic vinyl or rubber versions run between $150 and $350 installed, depending on your door's width and condition. The job takes an hour or less when there's no underlying damage.
Vertical side seals cost less individually but may need replacement on both sides. A full seal kit for all four sides typically ranges from $250 to $500 installed. If your threshold itself is cracked or warped, replacement costs climb to $400 to $600 because we need to remove and reinstall hardware.
Draft seals for the top of the door are less common but valuable in older homes or those with poor attic insulation. These typically add $75 to $150 to your total. If you're also considering garage door insulation, weather stripping should be done first to prevent air leaks around the perimeter.

Why DIY Seals Often Fail
You can buy adhesive-backed foam strips at a hardware store for $20 to $40. They're tempting because they're cheap. Don't use them on your garage door. Here's why.
Foam deteriorates faster than proper rubber gaskets in direct sunlight. It compresses under the door's weight and loses effectiveness within a season or two. Improper installation allows it to peel away mid-cycle, leaving debris in the track. We've removed countless failed DIY attempts that actually made the problem worse by trapping moisture underneath.
Professional seals are designed for the movement and pressure your door experiences thousands of times per year. They're manufactured to withstand Florida's heat and humidity. Installation requires the right tools, proper alignment, and often removal of the old gasket. We clean the frame thoroughly, apply seals level and tight, and test the door's operation before we're done.
Doing it right the first time saves you money over three to five years. A $300 professional installation beats three rounds of $40 foam strips and the headaches in between.

Frequently Asked Questions
How often should I replace weather stripping on my garage door? Every 6 to 8 years in Florida's climate. Inspect annually for cracks or hardening. If seals are visibly damaged, don't wait for the full cycle.
Can I replace just the bottom seal, or do I need all four sides? You can replace individual seals. However, if one has failed, others are likely close behind. We often recommend a full kit to avoid multiple service calls.
Will new weather stripping lower my energy bills? Yes, noticeably. Sealing air leaks can reduce heating and cooling loss by 10 to 15 percent, depending on how severe the draft was and your insulation level.
What's the difference between a bottom seal and a threshold? The bottom seal is the rubber gasket attached to the door. The threshold is the metal or vinyl track on the floor. Both work together; both may need replacement if water damage has occurred.
How long does a weather stripping installation take? Usually 45 minutes to an hour for a single seal, up to two hours for a complete four-side kit. We offer same-day service across Cortez and nearby areas.
