01
The assembly, not just the finish
Ask the window or door manufacturer for the exact coastal/exposure option and compatible fasteners, locks, rollers and finish. Different metals and coatings must be considered together; changing one visible handle does not upgrade every concealed component. A recommendation for roof fasteners near salt water cannot become a universal rule for door hardware.

Ownership and maintenance
Locate accessible surfaces and mechanisms for cleaning and inspection. Confirm cleaning frequency and methods from the selected supplier rather than publishing a guessed schedule. Save product codes and record the finish condition at handover. Visible staining, binding or pitting deserves assessment before substituting components.
03
What the proposal must include
The proposal should identify exposure package, fastener compatibility, protective finishes, installation damage repair and maintenance documents. Clarify whether all units receive the same package and whether screens or accessories differ. Ask for written exclusions tied to the specific site conditions; this guide promises no corrosion immunity.
04
Resolve before procurement
Compare complete unit schedules before placing orders. Ask the manufacturer to confirm the intended exposure in writing and the design team to reconcile it with performance needs. Do not use a universal distance from the coast as a substitute for that selection.
