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 South Carolina: South Carolina's coastal chimneys live on salt-air time: caps, dampers and chase covers corrode years early, and hurricane-driven rain tests every joint. Inland the humidity still rules: flues that never dry and smells that arrive in August.
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.
- Single flue, 304 stainless, fitted
- $150–$400
- Multi-flue cover, made to measure
- $500–$1,200
