Chimney and Vent Installation in Seattle

A new stove, insert, or fireplace needs venting sized and routed for that appliance. We install stainless steel liners, factory-built Class A chimney systems, direct-vent runs for gas units, and the caps and terminations that keep Seattle rain out.

When you need a new chimney or vent

Installing in Seattle homes

Seattle’s roofs are steep, wet, and mossy for much of the year. Roof penetrations get extra attention: flashing is layered into the roofing, storm collars are sealed, and terminations are chosen to shed rain rather than hold it.

Wood-burning appliances installed in Washington must be EPA-certified, and new installations typically need a mechanical permit from the City of Seattle or your local jurisdiction. We confirm the permit requirement before quoting.

What an installation costs

Cost depends on the appliance type, the height and route of the vent, and roof access. We visit, measure, and quote a fixed price for the complete installation including caps and flashing. Appliances can be supplied by you or sourced through us.

Questions about chimney installation

Yes. A factory-built Class A stainless chimney runs through the ceiling and roof or up an exterior wall and is the standard method for stoves in homes without a chimney.

Direct-vent gas fireplaces vent through a wall or roof with a sealed pipe and do not need a chimney. Gas log sets installed in an existing masonry fireplace use the existing flue.

Most liner and direct-vent installations are one day. Class A chimney runs through multiple floors can take two.
