Everything metal on the chimney rusting years early?
- Rust on caps, screens or chase covers within sight of the water
- Orange streaks down siding or masonry from the top
- Parts failing at half the age they reach inland
Why it happens in Norfolk: Norfolk pairs salt air with old brick, which is a harder combination than either alone: the metal corrodes on the schedule the coast sets, while the century-old masonry takes storm-driven salt water into lime joints. Add the flooding this city knows too well, and chimney bases and cleanout doors see water from below as well as above, a check most inland inspections never think to make. On Ghent's stacks that means reading the brick from the bottom up: rising damp and tidal salt work from the base while the nor'easters work from the top, and the two meet in the middle years sooner than either would alone.
What fixes it, and what it costs
On the coast, metal is a wear item and the inspection is really a metal check. The fix is buying the fight once: stainless caps and covers with proper drip edges, fasteners to match, and the corroding parts replaced before they perforate, because once water is inside the chase or the flue, the salt has won a much bigger bill.
