Locate the gap before choosing material
Describe whether light appears along the bottom, at one corner, around the sides or between sections. A split or flattened seal is different from a door that rests unevenly. Note whether the problem developed gradually, followed an impact or appears only during rain. Photographs of the closed door and visible seal can help, provided they can be taken without reaching into moving joints or beneath an unstable door.
Match the seal and retainer
Bottom seals use different profiles and retaining arrangements. Width alone does not establish a replacement fit. Ask whether the existing retainer is sound and which compatible seal is proposed. Perimeter trim and bottom seals solve different contact problems, and a threshold product may introduce its own drainage or clearance considerations. Avoid buying a generic strip before the door model and attachment arrangement have been reviewed.
Do not conceal a travel problem
A larger seal is not the correct answer to every uneven gap. Track geometry, door condition, closing position and the floor can affect contact. Ask whether the door is seating as intended and whether a repair is needed before seal replacement. Do not increase opener force to compress a seal or alter brackets to push one side lower. The door must continue to travel and reverse according to its manufacturer instructions.
Understand the limits in rain
Garage doors and weather seals should not be assumed to create a watertight flood barrier. Wind-driven rain, standing water, driveway slope and drainage can require separate investigation. Describe where the water first appears and whether it collects outside the opening. Ask which part of the problem the proposed seal is expected to address, what may remain and whether another qualified trade should evaluate drainage or building-envelope conditions.
Request a complete scope
Ask about seal material, retainer work, perimeter trim, removal of old material and post-installation checks. Confirm any care instructions and avoid painting or treating a new seal without product guidance. Contact I-95 Garage Door with your city, the observed gap and safe photos to discuss supported work. A useful recommendation identifies both the seal's intended function and the conditions it cannot reasonably correct.
