Where does the gap appear?
Tell Luke’s whether debris enters under the door, light shows at a side or a strip has separated from its retainer. Those details help define the service. A door that reverses or fails to reach the floor also needs its operation assessed rather than simply adding a thicker seal.
Set expectations for rain protection
Share any pattern of water entry, including whether it starts at the driveway or side wall. Discuss seal replacement together with the condition of the opening. Weatherstripping is one part of the enclosure; it should not be represented as flood protection or a repair for unrelated drainage problems.
Your questions
Will a larger bottom strip fix a sloping floor?
Ask for the gap and the opening to be assessed first. The suitable profile depends on the installation, and a larger strip alone may not address the underlying mismatch.
Can damaged seals be reviewed during another repair?
Mention them in the request so the visit can include a discussion of their condition. Any additional work should be identified before it is approved.
