Caps, Dampers & Liners in Des Moines
Near the Sound, a cheap galvanized cap rusts out fast. We fit heavy stainless steel caps with spark arrestors and animal guards built to survive salt spray, replace corroded throat dampers, and install top-sealing dampers that stop heat loss and downdraft on windy bluff homes.
When salt-laden moisture has cracked clay flue tiles in an older Des Moines home, we reline with marine-grade stainless sized to your appliance, restoring a safe, corrosion-resistant path for smoke and gases.

Caps, Dampers & Liners — your questions
Why stainless instead of a cheaper cap?
Galvanized caps rust through within a few years in Des Moines salt air. Stainless costs a little more upfront but lasts and won't streak rust down your masonry.
How do I know if I need a new liner?
Cracked or missing clay tiles, a past chimney fire, or salt-driven corrosion all call for a reline. We confirm with a camera inspection before recommending one.
Will a top-sealing damper help with my windy bluff home?
Yes. It seals tight at the top of the flue, cutting the downdraft and heat loss that exposed waterfront chimneys are prone to.
