Describe how the gap changes across the width
A gap that grows toward one corner is different from a uniformly worn strip. Report the pattern from the outside while the door is safely at rest. If the assembly visibly leans, avoid further operation and request a mechanical check rather than a larger seal.
Agree what the visit is meant to improve
Ask whether the work addresses damaged rubber, a loose retainer or a compatible perimeter stop. Put the selected parts and excluded floor correction in writing. The objective is a suitable edge interface, not a promise that a strip can correct every difference in slab level.
Locate a broader project accurately
For The Hammocks, County address lookup and jurisdiction resources are linked for any related floor or opening alteration. Keep those project questions connected to the actual property. If an association also reviews exterior work, establish that process separately from choosing the mechanical repair.
Your questions
Can extra layers solve a sloping-floor gap?
Do not assume that. Have the floor interface and door position assessed, then compare a compatible seal with any separate surface work.
Should closing travel be changed to compress a new seal harder?
Do not use adjustments to mask poor fit or a mechanical fault. The operator and safety functions need to remain correctly configured.
