If your garage feels drafty, cold air is leaking through gaps around your door. Weather stripping and seals are the first line of defense. Most Fletcher homeowners ignore them until their heating bill spikes. That's a mistake. A worn bottom seal or threshold lets conditioned air escape, and you're paying for it every single month.
Fletcher's climate is no joke. We get real winters with temperature swings that stress every seal on your home. Your garage door sits in direct sun half the year, then freezes at night. That constant expansion and contraction breaks down rubber and vinyl faster than you'd think.
The bottom seal takes the worst beating. It compresses against concrete every time you close the door. Over 3 to 5 years, UV exposure and ground moisture make it brittle. Cracks form. The threshold (that metal or rubber strip at the base) gets bent or damaged. Suddenly you've got a quarter-inch gap letting in wind, dust, and cold air.
Most people notice the problem when their garage gets noticeably colder than it should be. That's already costing you. A single crack in the bottom seal can let in as much cold air as leaving a window cracked open all winter.
Let's talk money. A garage that isn't properly sealed can increase your home's heating costs by 10 to 15 percent. If your monthly heating bill is $150, that's $15 to $22 you're throwing away every month. Over a heating season, that adds up fast.
Energy loss isn't the only problem. Drafts bring moisture, insects, and debris into your garage. That affects your car, your tools, and anything else you store there. We've had customers call us after finding rust on their vehicles because of moisture seeping in around a bad bottom seal.
If your garage is attached to your home (which most Fletcher garages are), poor seals also let conditioned air escape from your living space. Your HVAC system works harder. The draft you feel near the garage door? That's expensive air leaving your house.
The good news: fixing this is straightforward and relatively affordable compared to other garage door repairs.

Here's where people get confused. Your garage door has multiple seals. The bottom seal is the rubber strip that hangs from the bottom panel. It makes contact with the concrete floor. The threshold is the metal or rubber strip mounted on the floor itself.
Both wear out, but at different rates. The bottom seal typically needs replacing every 3 to 5 years in our climate. The threshold lasts longer, but can get bent or cracked if something heavy rolls over it.
You also have side seals and top seals that run along the sides and top of the door. These can develop gaps too, especially if your door has settled or the frame has shifted (common in older Fletcher homes).
During a tune-up inspection, we check all of these. Most of the time, the bottom seal is the culprit. But we don't guess. We measure and show you exactly where the air is getting in.
We get calls every week from Fletcher homeowners asking about cost. A bottom seal replacement typically runs $150 to $300, depending on your door type and whether the threshold needs work too. If you need both the seal and threshold replaced, budget $250 to $400.
That sounds like money until you do the math. At $20 a month in wasted heating, that repair pays for itself in less than a year. Plus you get a more comfortable garage and better protection for everything inside it.
Many of our customers schedule a free quote to get an exact price for their specific door. No obligation. We can often do the work same-day if you call early in the morning.
The sooner you address this, the better. Every month you wait, you're losing money to drafts.
Once we install new seals, keep them in good shape. Every few months, inspect the bottom seal for cracks or compression issues. If it's not making full contact with the floor, let us know. A small adjustment now prevents a bigger problem later.
Keep the threshold clear of debris and ice. In winter, ice buildup can damage the seal when the door closes. A quick sweep keeps everything functioning smoothly.
If you notice drafts returning within a year or two, don't wait. Call us and we'll take a look. Sometimes a seal shifts or the door frame settles, and we can make a minor adjustment.
Your garage door works hard. Proper seals keep it working efficiently and keep your home comfortable. That's the Fletcher Garage Doors approach: fix the right thing the first time.
How long do garage door seals last in Fletcher? Bottom seals typically last 3 to 5 years depending on sun exposure and use. Thresholds often last longer. Our climate's temperature swings accelerate wear, so inspect them annually.
Can I replace weather stripping myself? You can, but it requires removing the door or lifting it slightly. One mistake and you've got a misaligned door. Most homeowners save money and frustration by hiring a pro.
Will new seals reduce my heating bill? Yes. A properly sealed garage door can save 10 to 15 percent on heating costs, depending on insulation and how much you use the space. You'll notice the difference immediately.
What's the difference between a bottom seal and a threshold? The bottom seal hangs from the door and compresses down. The threshold is mounted on the floor. Both must work together to stop drafts effectively.
How do I know if my seals are failing? Look for visible cracks, compression loss, or daylight showing under the door. Feel for drafts. If your garage is noticeably colder than it should be, seals are likely the issue.
