Caps, Dampers & Liners in Mercer Island
We fit caps that fit the home — from clean stainless to custom copper and powder-coated designs that complement Island architecture — all with spark arrestors and fine-mesh guards to keep out the Island's abundant debris and wildlife. We replace tired dampers and install energy-saving top-sealing dampers as well.
For relining, we size each liner to its specific appliance. Gas units need a liner that resists acidic condensate; wood units need the right diameter for safe draft. In multi-flue homes we get each one right rather than applying one solution to all.

Caps, Dampers & Liners — your questions
Do you offer custom or copper caps?
Yes. Many Mercer Island owners want caps that match the home's architecture, so we offer custom copper and powder-coated options alongside standard stainless, all with proper spark arrestors and guards.
Why does a gas fireplace need a special liner?
Gas combustion produces acidic condensate that corrodes ordinary flues. We install liners rated for gas to protect the chimney and keep venting safe.
Can different flues in my home need different liners?
Yes — and they often do. Wood and gas appliances have different diameter and material requirements, so we size each liner to its specific appliance rather than using a one-size approach.
