Five signs your garage-door seal needs attention
A seal helps manage the gap it is designed to cover. When it wears, you may notice damage or a change around the opening. We can help identify the right seal for your door and check whether the cause also involves alignment, the floor or the surrounding building.
1. Visible cracks, tears or separation
Look from a safe position for split, brittle or displaced material. Do not put fingers between the bottom rail and floor or reach into moving hardware. Record the door model and the affected area so your dealer can identify the correct seal and carrier.
2. A gap that has changed
A gap can come from a worn seal, but it can also involve door alignment or an uneven floor. Do not alter the opener’s closing limit or force to press the door harder against the ground. Ask for the cause to be assessed before ordering a replacement part.
3. Water entering near the opening
Note where and when water appears. The threshold, driveway slope, drainage or surrounding frame can contribute. A new seal may help with the intended gap, but it cannot guarantee a watertight garage or replace drainage work. Keep stored items away from an affected area while the cause is assessed.
4. More dust or draughts
Inspect the bottom, sides and top separately. A compatible brush, jamb or lintel seal has a particular fitting arrangement and needs adequate movement clearance. Temperature change alone does not prove that the seal has failed; the roof, walls and ventilation also influence the space.
5. New contact noise at the floor
A hardened or displaced seal can be one reason for a change at closing, but noise or shuddering can also indicate a mechanical problem. Stop using a damaged, uneven or struggling door. Do not treat seal replacement as a cure for every closing fault.
Match the replacement and check the installation
Seal profiles and carriers vary between roller and sectional doors. Ask your dealer to identify the correct part, fitting scope and any rated-system requirements. If the door uses a documented bushfire or wind-rated configuration, changes must preserve that specification. There is no universal replacement interval or promise that fitting takes only minutes.
Keep warranty and upgrade choices separate
Seals may have different cover from the main door under the applicable terms. Replacing one does not itself create or renew a 10-year warranty. For an eligible new sectional door, insulation and seals can be considered together; for an existing door, start with the actual fault and compatible replacement. Arrange an assessment or explore our insulation and seal options.
