Small openings around a garage door can let in rain, dust, leaves, and outdoor air. A simple visual inspection can help you spot where the door no longer meets the floor or frame evenly. You do not need special tools: choose a bright time of day, look along the full perimeter, and note any visible light or uneven contact. This quick check can help you decide whether the seal needs attention or the door needs professional adjustment.
Start With a Safe Visual Check
Park vehicles and move stored items away from the doorway so you can see the bottom edge and both sides. Keep your hands clear of the door and its moving parts. Inspect the door while it is closed, and do not disconnect the opener or try to adjust springs, tracks, or cables as part of a basic gap check.
Look from inside the garage toward the closed door during daylight. Light showing through can reveal an opening, especially near a corner or where the bottom seal meets the floor. If daylight is limited, ask someone to shine a flashlight from outside while you observe from inside. Check only from a safe position, without standing under a moving door.
Inspect the Bottom Edge
Follow the entire bottom edge from one corner to the other. Look for visible light, a section of seal that is flattened or split, and spots where the rubber or vinyl does not touch the floor. Pay attention to the corners, where the bottom seal meets the side seals, because small breaks can be easy to overlook.
Check the floor as well as the seal. A gap may come from a low spot, crack, or uneven surface rather than a damaged seal. Note whether the opening runs across the width or appears only in one place. If the door looks crooked, sits unevenly, or leaves a large opening, avoid forcing it and arrange a professional inspection.
Check Both Sides
With the door closed, inspect the left and right edges from top to bottom. Look for daylight between the door and the frame, missing sections of side seal, or weatherstripping that has pulled loose, curled, or become compressed. Compare both sides; a noticeably wider gap on one side can indicate uneven contact.
A consistent, narrow line may be less concerning than a gap that changes sharply or exposes the interior to rain or debris. Note where the opening begins and ends, and take a photo if it will help you describe the issue. Do not pull on a seal that appears attached to a track or pinch your fingers between the door and frame.
Record What You Find
Write down the location and approximate length of each opening, such as “bottom right corner” or “left side near the floor.” Also note any torn, brittle, or loose seal material and whether you see water marks, leaves, or dust inside. These details make it easier to compare conditions later or explain the problem when requesting service.
If you find a small opening and the door otherwise closes evenly, the weather seal may be worn or poorly seated. A door that binds, appears out of alignment, or has damaged hardware needs more than a visual seal check. Leave mechanical adjustments to a qualified technician; garage door springs and cables can carry dangerous tension.
A careful walk-around, with daylight or a flashlight, can reveal gaps along the bottom and sides before they become harder to manage. Record what you see and avoid adjusting door hardware yourself. If you spot uneven contact, damaged seals, or a persistent opening, contact Savannah Seal Co. to discuss a professional assessment.
