Seal Out Moisture, Pests, and Drafts

America's Garage Doors LLC replaces worn or damaged bottom seals and perimeter weather stripping throughout Jacksonville, Jacksonville Beach, St. Augustine, and surrounding areas, protecting attached garages from moisture, pests, and temperature loss. You notice weather stripping failure when you see daylight under the closed door, feel drafts coming through gaps along the sides or top, or find water pooling inside the garage after rain. Over time, rubber seals dry out, crack, and lose their flexibility, especially in humid and coastal environments where exposure to salt air and UV light accelerates deterioration.

Compromised weather stripping allows rain to flow under the door and into the garage, leading to damp floors, rust on metal tools and equipment, and potential water damage to stored belongings. Gaps along the sides and top of the door also provide entry points for insects, rodents, and small animals seeking shelter. In attached garages, poor sealing reduces the effectiveness of your home's heating and cooling system by allowing conditioned air to escape and outdoor air to enter, which increases energy costs and reduces comfort in adjacent rooms.

If you see visible gaps, feel drafts, or notice moisture inside your garage after storms, schedule weather seal service to restore a tight, protective barrier.

The bottom seal, also called the astragal or threshold seal, is the most critical component because it bears the weight of the door and faces constant exposure to ground moisture and debris. America's Garage Doors LLC removes the old seal by sliding it out of the retainer channel along the bottom edge of the door, then installs a new seal made from durable vinyl or EPDM rubber that resists cracking and compression. The perimeter seals along the sides and top of the door are replaced by removing the old material from the track stops and jamb, then securing new bulb-style or fin-style seals that compress against the door when closed.

Once the new weather stripping is installed, you will notice that the garage stays drier after rain, fewer insects enter the space, and temperature swings are less pronounced. The door will also close more quietly because the seal provides cushioning between the door and the frame. Properly installed weather stripping reduces dust and pollen infiltration, which is especially noticeable during high-wind conditions or when nearby construction or landscaping activities stir up debris.

The service includes checking the alignment of the door to ensure even contact with the seals along the entire perimeter. If the door is warped or the track is misaligned, gaps may persist even with new seals, and those issues may need to be addressed separately. The work does not include adjustment of the door springs, replacement of panels, or track realignment unless those services are requested in addition to weather stripping.
