Savannah’s humidity, wind-driven rain, and warm temperatures can make a worn garage door seal noticeable. Water may creep under the door, damp air can enter around the edges, and pests may find small gaps. The right fix depends on where the opening is and how the door meets its frame. Compare the seal locations first, then choose a material that stays flexible and fits your door without interfering with its movement.
Start With the Leak Location
Check the door when it is closed, preferably during daylight. Look for light beneath the bottom edge and along both sides and the top. A gap only at the floor points toward the bottom seal or an uneven threshold. Gaps beside or above the door usually call for perimeter weatherstripping attached to the jamb or header.
Also inspect the floor and door alignment. A sloped, cracked, or uneven garage floor can leave a gap even when the bottom seal is intact. A door that sits crooked, binds, or leaves uneven spacing may need adjustment before new weatherstripping will seal reliably. Keep clear of springs, cables, and other moving hardware while inspecting.
Match the Seal to Its Location
The bottom seal presses against the floor when the door closes. Common designs slide into a retainer on the door and use a bulb, U-shaped, or T-shaped profile. Match the profile to the retainer groove and choose a thickness that closes the gap without making the door difficult to shut. If the opening varies across the floor, a new seal alone may not solve it.
Side and top seals attach to the frame and meet the closed door’s outer face. Vinyl or rubber stop molding can help block rain and drafts around the perimeter. For Savannah homes, look for a close, continuous fit and secure attachment; wind-driven rain can enter through small breaks at corners or where the molding has pulled away.
Choose Materials for Coastal Weather
Rubber and flexible vinyl are common choices for garage door seals. Both can form a useful barrier when sized and installed correctly, but quality, exposure, and upkeep affect how long they remain pliable. Select a product labeled for exterior use and check that it is compatible with the door and retainer. Avoid choosing by material name alone: profile and fit matter just as much.
A bottom seal faces abrasion from the floor, while perimeter molding must stay flexible through changing heat and moisture. Inspect seals periodically for cracks, flattening, loose fasteners, and shrinking at the corners. Clean off grit and leaves so they do not hold moisture against the seal or prevent the door from closing evenly.
Check Fit Before Replacing
Measure the door width and the gap at several points before buying a bottom seal. Note the retainer shape as well as the seal profile; similar-looking inserts may not fit the same channel. For side and top molding, measure each run and check whether the existing frame provides a sound surface for attachment. Take a clear photo of the retainer or molding to compare with product specifications.
After installation, close the door and check for continuous contact without excessive compression. Test the door’s operation and confirm that the seal does not catch, fold, or stop the door from closing. If water still enters, inspect the threshold, frame, drainage, and door alignment rather than adding thicker material at random. Persistent gaps or operating problems are good reasons to consult a garage door professional.
Choose weatherstripping by the gap’s location, the door’s retainer, and the conditions the material will face—not by appearance alone. A careful inspection and a few measurements can prevent a poor fit and help keep rain and humid air outside. For help identifying the right seal for your garage, contact Savannah Seal Co.
