In our years serving Del Valle, we've seen this problem again and again: homeowners ignore their garage door's weather stripping and seals until they're paying extra on energy bills or finding bugs inside. The good news is that replacing worn weather stripping and seals is one of the most affordable fixes we offer, and the payoff comes fast. A damaged bottom seal or threshold can cost you hundreds in wasted heating and cooling each year.
Your garage door's weather stripping and seals create a barrier between your home and the outside air. The bottom seal runs along the lowest edge of the door. The threshold sits on the concrete floor underneath. Side seals line the left and right jambs. Together, they block wind, dust, insects, and temperature swings from entering your garage.
When these wear out (usually after 5 to 8 years), drafts sneak in. Your HVAC system works harder. Spiders and roaches find their way inside. In Del Valle's hot summers, that draft means your air conditioning runs longer and your electric bill climbs.
The fix is straightforward: replace the damaged strips with new ones. Most jobs take under an hour.
Look for these red flags. Visible cracks or gaps in the rubber or vinyl seal are the clearest sign. You might notice a dark line of dirt or mold along the bottom of the door, which indicates air (and moisture) is flowing through. On a windy day, stand inside your garage with the door closed. Do you feel a breeze along the bottom or sides? That's a draft you can eliminate.
Another clue: insects appearing in your garage more often than before. Ants, wasps, and beetles exploit small gaps in seals. If you've noticed increased pest activity, your weather stripping may be failing.

Pricing for weather stripping and seal replacement depends on which seals need work and your door's size. A bottom seal replacement typically runs between $150 and $300. Adding side seals or a new threshold might push the total to $350 to $500. That sounds like real money, but consider this: a poorly sealed garage can waste $200 to $400 per year in energy costs alone. You recover your investment within a year or two, then enjoy savings year after year.

You might be tempted to buy DIY weather stripping kits online. Some homeowners do it themselves and save money short term. But professional installation ensures a tight fit that actually stops drafts and lasts longer. We measure precisely, use the right adhesives and fasteners, and guarantee the work.
A poor installation leaves gaps. A professional installation creates a true seal. That difference shows up on your energy bill and in your comfort level. For more on how sealing relates to overall garage door efficiency, check out our guide on garage door insulation in Del Valle.
Del Valle sits in central Texas, where summers push past 95°F and humidity can be high. Winter brings occasional cold snaps. Our climate puts extra stress on seals because of the temperature swings and occasional severe weather. Hail storms and heavy wind can damage seals faster than in milder regions. Austin and surrounding areas see similar wear patterns.
Keeping your weather stripping in good shape protects your garage from our weather extremes. It keeps your garage cooler in summer, helps retain heat in winter, and protects your garage door hardware from rust and corrosion.
When you call Garage Door Del Valle for a seal or stripping issue, we inspect the entire garage door system. Sometimes the seal itself is fine, but the door isn't closing flush against the frame. We check alignment, springs, and hardware. We give you an honest assessment of what actually needs fixing.
We source quality replacement materials and install them right the first time. Our team knows the local climate and chooses seals rated for Texas heat and humidity. Explore our full weather stripping service to see what's included.

Your garage door works hard to protect your home and your vehicles. Keeping the seals in shape is a small maintenance task that pays big dividends.
How often should weather stripping be replaced? Most weather stripping lasts 5 to 8 years depending on climate and use. In Del Valle's heat and humidity, we typically see wear closer to the 5 to 6 year mark. Inspect yours annually and replace when you notice cracks, gaps, or visible deterioration.
Can I replace weather stripping myself? Yes, but professional installation is more durable and precise. DIY kits sometimes leave small gaps that let air and pests through. If you're handy and patient, it's doable. For a guaranteed seal, hire a pro.
Will new weather stripping reduce my energy bill? If your garage is sealed and insulated, yes. A sealed garage keeps conditioned air in and outside air out. You'll see savings of $150 to $300 per year on average, depending on your door's current condition and your climate control habits.
What's the difference between a bottom seal and a threshold? A bottom seal is the rubber or vinyl strip attached to the bottom of the door itself. A threshold is the aluminum or rubber piece fastened to the concrete floor. Both create a seal when the door closes. Some doors have one, some have both.
How do I know if my seals are damaged? Look for visible cracks, gaps, or missing pieces. Feel for drafts with your hand. Check for dirt lines, mold, or insects near the seals. A professional can also identify damage during a free inspection.
