Cap: $150 to $700 installed. Crown seal: $225 to $600. Crown rebuild: $800 to $2,500.

FAQs, Chimney Cap & Crown Repair Cost
$150 to $350 installed for a standard single-flue stainless cap with a mesh spark arrestor. Copper caps and multi-flue chase covers run higher.
The crown is the concrete or masonry slab that tops the chimney structure. The cap is the metal cover that sits over the flue opening to block rain and animals. Most chimneys need both.
If the crown has hairline cracks but is structurally sound, a $300 to $600 waterproof coating buys 10 to 15 years. If it's crumbling or has structural cracks, rebuild it now to avoid destroying the masonry below.
For a standard single-flue chimney with easy roof access, yes: DIY caps run $60 to $150. But you lose warranty coverage and any mistake sitting 25 feet up costs more than the install.
20 to 30 years for a quality 304 or 316 stainless cap. Galvanized caps rust out in 5 to 10 years and shouldn't be used.
