— Chimney Caps
Made-to-measure caps in copper, galvanized, or painted steel.
A chimney cap does three jobs: it keeps water out of the chimney, it keeps animals out of the chimney, and — visually — it's often a major architectural element. Off-the-shelf caps fit none of these jobs well. Custom caps fit all three.
Knox fabricates chimney caps in our 4,000 sq ft sheet metal shop, sized to your exact chimney and detailed to your home's architecture. Copper for premium and historic homes; galvanized or painted steel for cost-sensitive projects — all made to measure.

Copper for premium and historic homes — it patinas beautifully and lasts a century. Painted or galvanized steel for cost-sensitive projects — still custom-fit, just lower material cost.
A properly designed cap won't — we maintain required flue area plus margin. Poorly sized caps can reduce draft; we don't build those.
Yes — top-sealing dampers integrated with the cap are a common upgrade for existing chimneys.
We build engineered caps for multi-flue chimneys with proper separation and individual screen sections.
