In our years serving Schertz homeowners, we've seen this problem again and again: a garage door that looks fine from the outside but leaks conditioned air and lets in Texas heat like a sieve. The culprit? Worn weather stripping and seals. A failing bottom seal or threshold doesn't just waste energy. It invites pests, lets moisture creep in, and can cost you hundreds in AC bills over a single summer season.
The good news is straightforward: replacing weather stripping and seals is one of the highest-return maintenance tasks you can do. We'll walk you through why Schertz homes struggle with this, what to expect cost-wise, and how to know if yours need attention now.
Our Texas climate is brutal on rubber and foam. Summer temperatures regularly exceed 95 degrees, and the intense UV radiation degrades seal materials faster than in cooler regions. The bottom seal takes the worst beating. It flexes every time your door opens and closes, sits in direct sunlight, and collects dirt and debris that abrade the material.
Most original seals last 5 to 7 years in Schertz conditions. If your garage door is older than that, don't assume the seals are still doing their job. A visual check is quick: look at the bottom seal and side seals. If they're cracked, flattened, or pulling away from the frame, you've got a problem.
Drafts around the sides and top are harder to spot but just as costly. Air leaks through gaps that seem invisible. Your AC works overtime cooling a space that's losing conditioned air to the outdoors. In summer, this translates to 10 to 20 percent higher cooling costs for many Schertz homes.
Not all weather stripping is the same. The bottom seal (also called a threshold seal) is the most critical. It bears weight, endures traffic, and contacts the ground. Quality replacement bottom seals run $150 to $400 depending on door width and material. A rubber bottom seal is standard; some homeowners upgrade to rubber-and-vinyl composites that last longer.
Side seals and top seals are usually foam or rubber strips that run along the frame. These are less expensive per unit, around $50 to $150 each, but your door might need all three to eliminate drafts entirely.

Professional installation matters more than you'd think. A poorly fitted seal will gap or compress unevenly, defeating its purpose. We've seen DIY attempts that cost homeowners more in wasted AC than they saved on labor. The frame has to be clean, the seal material must be the right thickness, and tension must be even across the entire length.
If you're weighing cost against benefit, consider that a complete seal replacement typically costs $400 to $700 installed. Over five years, the energy savings alone often cover that investment. Add in pest prevention and moisture control, and the math gets even better.
A draft isn't just an inconvenience. Water and humidity seep in around a failing bottom seal, especially during Schertz thunderstorms. Moisture in the garage creates rust on metal components, mold on walls, and can damage stored items. If your garage is partially climate controlled or adjoins your home, leaks compromise your entire envelope.
Pests also exploit gaps. Insects, rodents, and even snakes have found their way into garages through cracked seals. Once inside, they can enter the home itself. Proper sealing is a first line of pest defense that many homeowners overlook.

Professional installation ensures seals sit flush against the frame with correct tension. We measure twice, fit once. The door should close smoothly without binding, and you should feel no draft from inside the garage.
After installation, keep your seals clean. Dirt buildup accelerates wear. Rinse the bottom seal monthly during dusty seasons, and wipe side seals with a damp cloth. This simple habit extends seal life by 2 to 3 years.

How long do weather stripping seals typically last in Schertz? Quality seals last 5 to 7 years in our Texas heat and UV exposure. Original manufacturer seals may only last 4 to 5 years. Inspect them annually after year four to catch failure early.
Can I replace weather stripping myself? It's possible, but professional installation ensures proper fit and tension. A poorly installed seal wastes money and energy. The cost difference is usually small; expert fitting is worth it.
What's the average cost estimate for complete seal replacement? A full set (bottom, two sides, and top) typically runs $400 to $700 installed, depending on door size and seal material quality. We always give a free estimate before work begins.
Do weather seals affect garage door safety? Not directly, but they do protect the door mechanism from moisture and debris, which extends the life of springs and hardware. See our garage door safety guide for details on other critical safety systems.
Will new seals stop all drafts? Quality seals eliminate most drafts, but doors with warped frames or damaged panels may still leak slightly. We assess the entire door during inspection and recommend other repairs if needed.
