Weather Stripping & Seals in Crandall: Stop Drafts and Save on Energy
2026-04-29 7 min read
If your garage feels like a sauna in July or an icebox in January, your weather stripping and seals are likely worn out. A failing bottom seal and deteriorated threshold don't just waste energy.they let pests in, reduce security, and can cost you hundreds in utility bills annually. I've seen it happen countless times across Crandall and the surrounding areas.
Why Weather Stripping Fails (And Why It Matters)
After 15 years on the job, I can tell you that weather stripping doesn't last forever. The rubber and vinyl materials that form your garage door's bottom seal, side seals, and top threshold degrade from UV exposure, temperature swings, and constant flexing. In Texas, where we go from blistering heat to occasional cold snaps, that breakdown accelerates.
A compromised seal creates a draft that works both ways. Hot air escapes in summer; cold air leaks in during winter. If your garage is insulated or climate-controlled, you're paying to condition air that's literally flowing out through gaps. Even an unfinished garage suffers.pests, dust, and debris find their way inside.
The good news? Catching this early is simple. Look for visible cracks, missing chunks, or daylight showing under the door when it's closed.
Types of Seals and Where They Wear First
Your garage door has three main seal areas: the bottom seal (or astragal), the side seals, and the top threshold.
The bottom seal takes the most abuse. It compresses every time the door closes, making contact with your concrete floor. Over time, it flattens, shrinks, and cracks. In Crandall homes with older concrete, uneven floors can accelerate wear because the seal can't maintain consistent contact.
Side seals prevent drafts from creeping in along the vertical tracks. These often wear unevenly if your door is slightly misaligned.another reason regular maintenance pays off.
The top threshold seals the gap between the door and the header frame. Wind-driven rain and temperature fluctuations hit this area hard, making it vulnerable to premature failure.

Signs Your Seals Need Replacement
You don't need to wait for a problem to become obvious. Here are the warning signs I look for:
- Visible damage: Cracks, peeling, or missing pieces of rubber or vinyl. - Daylight under the door: Close the door and look at the floor from inside. If you see light, the seal isn't doing its job. - Drafts or temperature inconsistency: Feel around the door frame with your hand on a windy day. - Pest activity: Finding bugs or rodents near the garage? A worn seal is an open invitation. - Rising energy bills: This one's subtle but real. Homeowners don't always connect higher AC costs to a bad garage door seal.

What Replacement Costs and What to Expect
The cost of weather stripping and seal replacement is one of the most affordable maintenance jobs you can do. A bottom seal replacement typically runs $150,$300 for materials and labor, depending on your door size and seal type. Side seals and threshold work might add another $100,$200.
Getting an accurate estimate means having someone inspect your specific door. Every garage is different.some doors use standard seals, while others require custom measurements. When you call for an estimate, we'll assess all three seal areas and give you a clear breakdown.
If you're dealing with other issues.say, worn panels or spring problems.seal replacement pairs well with those repairs. It's often more efficient to handle multiple issues at once. For context, check out our panel repair guide if you suspect damage beyond just the seals.
DIY vs. Professional Replacement
I'll be honest: some homeowners can replace a bottom seal themselves if they're handy. The process involves releasing tension, removing the old seal, and installing the new one. It's not complicated, but it requires care and the right tools.
Where most people run into trouble is with side seals and thresholds. Those require precise alignment and sometimes involve adjusting the door itself. Getting it wrong means the door won't close properly or seal at all.
For most folks in Crandall, professional installation is worth the peace of mind. We get it done right the first time, and you don't risk damaging the door or frame in the process.
Protecting Your Investment Long-Term
Weather stripping typically lasts 5,7 years depending on climate and maintenance. In North Texas, where summer heat is relentless, plan for replacement closer to the 5-year mark. Regular inspection.once a year, ideally in spring.catches problems before they become expensive.

Frequently Asked Questions
How long does weather stripping last? Quality weather stripping typically lasts 5,7 years in North Texas. UV exposure, temperature extremes, and constant door movement all accelerate wear. Annual inspections help catch degradation early.
Can I replace weather stripping myself? Bottom seals are DIY-friendly for handy homeowners, but side seals and thresholds often require professional installation to ensure proper alignment and a complete seal. Mistakes can reduce effectiveness significantly.
What's the difference between a bottom seal and a threshold? A bottom seal (astragal) is the rubber or vinyl gasket on the door itself that compresses against the floor. A threshold is the structural piece at the base of the door opening. Both work together to block drafts and pests.
How much does seal replacement cost near Crandall? Expect $150,$500 total, depending on which seals need work and door size. Bottom seal replacement alone runs $150,$300. Call (469) 287-0325 for a detailed estimate based on your specific door.
Will new seals reduce my energy bills? Yes, noticeably. A proper seal prevents heated or cooled air from escaping, especially in insulated or conditioned garages. Many homeowners see a 10,15% reduction in cooling costs during summer months.
