Building a new chimney — for an addition, a new fireplace or stove, or to replace one that was removed — is a project where the details drive the price. The biggest factor is whether you're installing a prefab (factory-built) chimney system or constructing a full masonry chimney. This guide breaks down real 2026 new-chimney pricing across the Seattle area and how to get an honest, itemized quote.
What new chimney construction costs in Seattle
A prefab chimney system — a factory-built metal flue and chase suited to a stove or a manufactured fireplace — runs about $1,500–$2,500. A new masonry chimney, built from brick or block with a poured crown and cap, runs $2,500–$3,500. Height, the appliance it serves, roof access, and finishing all move the figure. We assess the whole project and hand you an itemized written quote so you see exactly what each part costs.
Prefab system or masonry chimney
A prefab system is faster and lighter, a good match for a new wood stove, gas unit, or manufactured fireplace, and it's the lower-cost route. A masonry chimney is built on-site from brick or block — it's the traditional look many Seattle and Tacoma homes call for, and it's the right choice for a true masonry fireplace. We'll walk you through which fits your appliance, your home's style, and your budget.
What building for the Puget Sound involves
A chimney built here has to stand up to constant rain and freeze-thaw from day one. That means a properly sloped, overhanging crown, a good cap, correct flashing where it meets the roof, and — on masonry — brick and mortar rated for our wet climate. On older or seismically sensitive homes we build with stability in mind. Doing it right at construction is far cheaper than chasing leaks and repairs later.
How to get an honest construction quote
A real new-chimney quote comes after someone reviews the appliance, the roof, and the framing — not from a flat number. Ask whether a $1,500–$2,500 prefab system will serve your appliance before committing to a $2,500–$3,500 masonry build. A good builder matches the chimney to your fireplace or stove and spells out materials, height, and flashing in writing.
