Weather stripping and seals stop drafts, lower your energy bills, and keep pests and moisture out of your garage. A worn bottom seal alone can cost you $200+ annually in wasted heat. If you've noticed cold air creeping in or your garage feeling damp, it's time to replace them—and we'll walk you through the signs and solutions right here.
I've been servicing garage doors across Lillington and the surrounding Harnett County area for fifteen years. One thing I've learned: homeowners often overlook weather stripping until winter hits hard or they see a pest problem. By then, the damage is already done. Let's cut through the confusion about what weather stripping actually does and when you need to act.
Your garage door isn't just a barrier for your car—it's part of your home's thermal envelope. Every gap and crack is money walking out the door, literally.
Weather stripping seals the sides and top of your door frame. The bottom seal, or threshold, does the heavy lifting: it creates a tight seal between the door and the floor. Together, they block:
- Heat loss (or gain, in summer) - Drafts and cold air infiltration - Moisture and humidity - Insects, rodents, and debris
Think of it this way: a single 1/8-inch gap around your garage door is like leaving a small window cracked open all winter. Over three months, that costs real money. A quality bottom seal and side weather stripping reduce that loss significantly—typically 10–15% of your garage heating expenses, depending on insulation and climate.
Lillington winters are mild compared to the north, but we get enough cold snaps and rain that proper seals matter. Moisture creep is especially common here; I've seen it damage stored items, tools, and car undercarriages.
Seals wear out. They compress, crack, and harden over 5–7 years depending on material and sun exposure.
Watch for these red flags:
- Visible cracks or gaps in the rubber or foam - Cold air draft along the bottom or sides when the door is closed - Water pooling inside after rain or during humid spells - Pest droppings or evidence of rodent/insect entry - Visible daylight peeking through the frame edges
If your garage feels noticeably colder than it should or you've had to seal gaps with caulk or tape, the original seals have probably failed. Don't wait for full deterioration—small gaps turn into big problems fast.
Not all weather stripping is created equal. I cover this in detail in our material selection guide, but here's the quick version:
Rubber seals (EPDM or neoprene) are durable, flexible, and last 7–10 years. They handle UV and temperature swings well. Cost: $150–$300 for a full door replacement.
Foam seals are cheaper upfront ($50–$100) but compress faster and may only last 3–5 years. They're fine for mild climates or temporary fixes.
Vinyl threshold seals are common at the bottom and offer good durability if properly installed.
The real cost isn't the material—it's the installation. If you hire someone to do it right, expect $200–$400 total for quality materials and labor. That pays back in energy savings within one heating season if you're in a cold climate. Even in Lillington, where winters are gentler, the ROI is solid over three years.

You can buy weather stripping kits online and install them yourself. It's doable if you're handy. Measure twice, clean the frame thoroughly, and follow the manufacturer's adhesive instructions.
But here's my honest take: a professional install ensures the seal is tight and properly seated. Gaps during DIY installation defeat the whole purpose. If you're not confident, call us. We'll give you a free estimate and handle it the same day in most cases.
Also, if your door has underlying frame damage or the bottom seal track is bent, DIY won't fix that. We diagnose and repair those issues so your new seals actually work.
Weather stripping lasts longer if you maintain it. Clean the frame and seals every spring to remove dirt and debris that can prevent a tight seal. If you're preparing your garage door for fall, check the seals then too—don't wait until November when it's cold and wet.
In Lillington, our humidity can cause mold growth around old seals. A quick inspection and cleaning in spring keeps that at bay.
Install or replace weather stripping yourself if you're comfortable with basic home maintenance. But call Lillington Garage Doors if:
- Your frame is warped or damaged - The bottom seal track is bent or rusted - You want a same-day replacement and professional guarantee - You're unsure which material suits your door and climate
We'll inspect your entire door assembly, not just slap on new seals. That thoroughness is what keeps your garage protected long-term.

How long do weather stripping and seals last? Quality rubber seals typically last 7–10 years. Foam seals wear faster, usually 3–5 years. Lifespan depends on sun exposure, temperature swings, and maintenance. Regular cleaning extends it.
Can I replace weather stripping myself? Yes, if you're comfortable measuring and applying adhesive. The main risk is improper seating, which leaves gaps. Professional installation guarantees a tight fit and comes with a service warranty.
How much does weather stripping cost? Materials run $50–$300 depending on type. Professional installation adds $150–$200. A full replacement typically costs $200–$400. Get a free estimate from us to know your exact cost.
Will new seals really save me money? Yes. Poor seals waste 10–15% of garage heating energy. In Lillington's mild climate, payback takes 2–3 years. In colder regions, it's faster. You also avoid moisture damage and pest problems.
What's the difference between weather stripping and a bottom seal? Weather stripping runs along the sides and top of the frame. The bottom seal (or threshold) sits at the door's base. Both are essential; together they create a complete draft barrier.
