Let's cut through the confusion about weather stripping and seals. Your garage door's bottom seal and threshold strips do one critical job: they block cold air, pests, and moisture from entering your garage and home. If you're noticing drafts, higher heating bills, or visible gaps around your door frame, those seals are likely worn out. The good news? Replacing them is straightforward, affordable, and something we handle regularly here in Othello.
Weather stripping runs along the sides and top of your garage door opening. The bottom seal (also called a threshold seal) sits at the base where your door meets the floor. Together, they create an airtight barrier. In the Columbia Basin, where winter temperatures drop below freezing and summer heat climbs past 90 degrees, that barrier matters. A failing seal lets cold or hot air escape, forcing your HVAC system to work harder. See our guide on garage door repair in othello: troubleshooting before you call.
Most residential garage doors have rubber or vinyl seals. Rubber lasts longer and handles temperature swings better. Vinyl is cheaper but degrades faster under UV exposure. Both eventually crack, shrink, or harden from age and weather exposure. When that happens, you lose the draft protection they provide.
Look for these red flags. Visible gaps between the seal and frame mean it's time to act. If you feel air movement around the door on a still day, that's a draft problem. Daylight showing through the bottom seal is another clear sign. Sometimes seals pull away from the frame, or you'll notice they've become hard and brittle rather than flexible.

You might also see water stains on your garage floor after rain, or notice insects getting into the garage more often. These are signs your bottom seal has failed. Most seals last 5 to 8 years depending on climate and maintenance. Othello's dry summers and cold winters can shorten that lifespan, especially on south-facing doors that take direct sun.

Replacement cost depends on seal type and door size. A basic bottom seal replacement runs $150 to $350 for most single-car doors. Side and top seals add another $100 to $200 per section. If you need full threshold replacement (the metal track at the base), budget $200 to $400. We always provide a free estimate before starting work, so you know the exact cost upfront. No surprises, no hidden fees.
Labor takes 1 to 2 hours for a complete seal job on a standard door. Many homeowners ask if they can DIY this. You can, but improper installation leaves gaps. Seals must sit flush and tight. A professional installation ensures the seal actually stops drafts and protects your home.
If your door also has insulation issues, you might want to pair this work with our garage door insulation service to maximize energy savings.
Energy loss through a failed garage seal adds up fast. Your garage sits between your conditioned home and the outside. A gap in that barrier means your furnace or air conditioner compensates by running longer. In winter, you're essentially heating the neighborhood. In summer, you're cooling it. Over a heating season, a poorly sealed garage door can add 10 to 15 percent to your energy costs.
Replacing worn seals is one of the smartest ROI investments you can make. The cost typically pays for itself in energy savings within one heating season, especially in our cold-weather months. After that, it's pure savings.
If seals are cracked, pulling away, or completely missing, don't wait. The longer you leave gaps, the more damage moisture can do to your door frame and garage structure. Call us for a same-day estimate, and we'll handle the replacement quickly.

How long do garage door seals last? Most seals last 5 to 8 years in our climate. Rubber seals outlast vinyl. Direct sun exposure, freeze-thaw cycles, and regular use all shorten lifespan.
Can I replace weather stripping myself? Yes, but improper installation leaves gaps. Seals must sit flush and level. Professional installation ensures they actually block drafts and pests.
What's the difference between a bottom seal and a threshold? The bottom seal is rubber or vinyl attached to the door. The threshold is the metal track at the base of the opening. Both work together but serve different functions.
Will new seals reduce my energy bills? Absolutely. A failed seal lets conditioned air escape. Replacement typically pays for itself in one heating season through reduced heating costs.
