Describe the edge and retained channel
Note whether the problem is below the door, beside it or around visible trim. A photograph from a safe standing position can show the existing profile. Report an uneven door before asking for a wider seal, and avoid altering opener settings to force a tighter closure.
Coordinate access and any additional work
If the home is rented, identify the owner or manager approving changes as well as the resident contact. Palm Springs keeps building applications and rental licensing separate; use the relevant building process if the proposal expands into an alteration. Keep flooring, drainage and visible trim changes explicitly outside a seal-only scope unless included.
Your questions
Does a new bottom strip address every pest entry point?
No. Other openings around the garage may remain. Ask which gap is being treated rather than assuming whole-room exclusion.
Can the old retainer always remain in place?
Its condition and compatibility need assessment. A damaged channel may prevent the correct strip from fitting as intended.
