Locate the opening accurately

A tear along the bottom strip calls for a different discussion from daylight at a jamb or top corner. Explain where the gap appears when the door is already safely closed. Do not increase closing force or add layers of seal to hide an uneven door.

Repair the fit without promising a waterproof garage

The replacement needs to suit the door and retainer. Ask whether the floor or surrounding trim affects the result and which items belong in the quote. A perimeter seal is not a flood barrier; larger opening work should be assessed and coordinated with the City’s relevant project requirements.

Your questions

Can I describe the gap with a photo?

A safely taken closed-door photograph is useful. Include both the location and any visible seal damage without lifting the door to inspect loaded hardware.

Will a new seal stop water from every source?

No. Drainage, floor conditions and other entry paths can matter. Identify the source rather than assuming the door seal is the whole problem.
