Chimney Caps, Spark Arrestors & Dampers SF | Remarkable

Protection & efficiency

Chimney caps, spark arrestors & dampers

An uncapped flue is an open pipe to the sky: rain and fog pour in, warm air pours out, and raccoons treat it as a front door. A quality cap and a working damper are the least expensive protection a chimney can get.

What we install & service

Stainless & copper capsSized and anchored to your flue, in materials that survive salt air. No galvanized shortcuts.
Spark arrestorsEmber-stopping mesh — standard practice in fire-conscious California and built into every cap we fit on wood-burners.
Top-sealing dampersA gasketed lid at the crown that seals the flue when idle — heated air stays in the house, not the sky.
Throat damper repairSeized, rusted, or missing-plate dampers freed, adjusted, or replaced so your fireplace drafts properly.
Chase coversRusted factory chase tops on prefab chimneys replaced with welded stainless covers that shed water.
Animal exclusionHumane removal of birds and raccoons, nest clearing, and capping so they don't come back.

What a good cap prevents

Water damage

SF's fog and rain corrode dampers, sour creosote, and crumble mortar from the inside. A cap stops it at the top.

Roof ember fires

Arrestor mesh catches sparks before they land on shakes, decks, or your neighbor's roof — a real concern in dense SF blocks.

Uninvited guests

Birds, squirrels, and raccoons nest in open flues — blocking airflow and worse. Mesh keeps wildlife where it belongs.

Cap & damper questions, answered

Which cap material should I choose?

Stainless steel is the workhorse — it shrugs off salt air and carries lifetime manufacturer warranties. Copper costs more and develops a patina many owners of older homes love. We don't install galvanized caps; they rust quickly near the coast.

Do I need a spark arrestor?

On a wood-burning chimney in California, yes — it's standard practice and stops embers from reaching rooftops. Most quality caps integrate one; we make sure yours meets local requirements.

Will a top-sealing damper lower my heating bills?

An open or leaky throat damper lets heated air escape up the flue all winter. A top-sealing damper closes the chimney at the crown with a silicone gasket, keeping conditioned air in when the fireplace is idle.
