Why Your Garage Door Leaks Air in Kennedale (And How to Fix It)
2026-05-29 7 min read
In our years serving Kennedale, we've seen this problem again and again: homeowners lose hundreds of dollars to energy waste because their garage door weather stripping has deteriorated or come loose. A failing bottom seal or worn threshold allows cold air to pour in during winter and conditioned air to escape in summer. The good news is that weather stripping and seals are one of the most cost-effective repairs you can make. Replacing them properly stops the draft, lowers your utility bills, and protects your garage contents from moisture and pests.
How Weather Stripping Fails (And Why It Matters in Kennedale)
Garage door seals experience constant stress. Your door opens and closes thousands of times per year, compressing and releasing the rubber, vinyl, or foam that makes up the weather stripping. Texas heat accelerates this breakdown. UV rays, temperature swings from 30 degrees to 95 degrees, and occasional heavy rain all work against the seal's integrity.
The bottom seal takes the worst punishment. It sits closest to ground level, where water pools and debris accumulates. A failed bottom seal doesn't just waste energy. It invites rodents, insects, and moisture into your garage. That moisture can rust tools, damage stored items, and even affect your home's foundation over time.
Most homeowners don't notice the problem until they feel a draft or see daylight under the door. By then, the seal has usually been failing for weeks or months.
Signs Your Seals Need Replacement Now
Look for these red flags during your next inspection:
A visible gap between the door and the frame means the threshold or side seals have compressed. Feel around the edges on a windy day. If you detect a draft, that's your confirmation. Check the bottom seal itself. If it's cracked, peeling, or missing chunks, replacement is overdue.
You might also notice higher energy bills without an obvious cause, or pest droppings in corners of your garage. These are indirect signs that your door isn't sealing properly. Some homeowners report condensation on the inside of the garage door in cold months. That moisture comes from uncontrolled air exchange.
If your door is older than 10 years and the seals have never been replaced, they're almost certainly due for an upgrade.

The Right Way to Seal Your Garage Door
Not all weather stripping solutions work equally. Budget materials compress within a year. Professional-grade rubber and vinyl products last 5 to 7 years with proper installation. The threshold matters too. Your bottom seal must sit flat and flush against the concrete floor. If the concrete has settled or cracked, a new seal alone won't solve the problem.
This is why a proper estimate matters. We inspect the door frame, test the seal compression, and assess the floor condition before recommending a solution. Sometimes a new bottom seal is enough. Other times, you need side seals or a complete threshold replacement to stop the draft fully.
Installation takes precision. The seal must be compressed consistently across its entire length. Uneven gaps will let air through. Adhesive must cure properly before you operate the door. Rushing this step means the seal will fail again in weeks.
If your garage door has other issues, like misalignment or worn springs, address those first. A crooked door won't seal properly no matter how good your weather stripping is. Our team can check your garage door springs and overall alignment during the same visit.

Frequently Asked Questions
How long does weather stripping last? Quality garage door seals last 5 to 7 years under normal Texas conditions. Extreme heat, direct sun exposure, and frequent door cycles can shorten that lifespan. We recommend inspecting seals every 2 years.
Can I replace weather stripping myself? Basic bottom seal replacement is possible for handy homeowners, but side seals and thresholds require precision alignment. Professional installation ensures your seals compress evenly and last longer. Improper DIY installation often fails within months.
What's the difference between a bottom seal and a threshold? The bottom seal is the rubber or vinyl strip attached to the bottom of the door. The threshold is the horizontal track or barrier on the floor where the door closes. Both must work together to stop drafts completely.
Will new seals reduce my energy bills? Yes, especially if your current seals are missing or heavily worn. Energy savings typically range from 10 to 20 percent on heating and cooling costs, depending on your local climate and how much air was leaking through gaps.
Do I need to replace all my seals at once? Not necessarily. If only the bottom seal is damaged, replacing that alone may solve your problem. However, if your door is older or multiple seals show wear, replacing them all together ensures consistent performance and longer service life.
