Very little of what goes wrong in a coastal home announces itself. A seal stops sealing. A drain runs a little slower. A hinge carries salt it should not be carrying.

None of it is urgent on the day it starts. All of it is expensive on the day it finishes.

A scheduled walkthrough — same route, same checklist, same eyes — catches the small version of every one of these. The point is not vigilance. The point is repetition.
