Garage Door Weather Seal Replacement

The easiest test is the daylight check. Close your garage door during the day and look for light coming in along the bottom, sides, or top from inside the garage. If you see light, air and water are getting through too. Other signs include visible cracks or tears in the seal material, water on the garage floor after rain, cold drafts in winter, or evidence of pests entering the garage.

Side and top seals are relatively straightforward for handy homeowners. Bottom seals can be more involved, especially if the retainer needs replacing. The retainer sits near the bottom fixture, which is under spring tension. If you're not sure what you're working around, it's safer to call a professional. Threshold seals are DIY-friendly since they bond to the floor rather than the door.

In the St. Louis climate, most rubber and vinyl bottom seals last 5 to 7 years with normal use. Side and top seals can last longer since they see less direct contact and wear. Factors like sun exposure, humidity, how often the door is used, and whether the floor is level all affect lifespan.

It depends on your retainer type and floor conditions. T-end seals are the most common and work well on level floors with standard retainers. Bulb seals are better for uneven floors because they compress and conform to gaps. We inspect your door and floor to recommend the right match.

Yes. Air leaks around doors and windows can account for a significant portion of a home's heating and cooling loss. A properly sealed garage door, especially on an attached garage, reduces the amount of unconditioned air entering your home. The difference is most noticeable in winter and during peak summer heat.

The most common cause is a worn or damaged bottom seal. If the seal no longer makes full contact with the floor, water flows right under the door during heavy rain. An uneven garage floor or a sloped driveway can make this worse. A combination of a new bottom seal and a threshold seal usually solves the problem.

We inspect the retainer as part of our diagnosis. If it's in good condition, we replace only the seal. If the retainer is cracked, warped, or corroded, we replace it along with the seal. A damaged retainer will cause even a new seal to sit incorrectly and fail early.

It depends on which seals need replacing, the type of door, and whether the retainers need work. We provide a clear quote after our inspection, before any work begins.

Properly installed weather seals significantly reduce pest entry. Mice can squeeze through gaps as small as a quarter inch, and insects need even less space. Replacing worn bottom and side seals eliminates the most common entry points. For persistent pest issues, we may also recommend a threshold seal for added protection.
