Adding a fireplace — or replacing a tired one — is a project priced by what you're putting in and where. The biggest factor is whether you're fitting an insert into an existing opening or building in a new fireplace where there wasn't one, along with the venting and finishing involved. This guide breaks down real 2026 fireplace installation pricing across King, Pierce, and Snohomish counties.
What fireplace installation costs in Seattle
A fireplace insert installation, fitting a self-contained unit into an existing opening, runs about $2,000–$3,500. A new fireplace installation — building in a unit where none existed, with framing, venting, and finishing — runs $3,500–$5,000. The unit you choose, the venting path, and any framing or hearth work set the final figure. Every project gets a free written quote before we start, a free second opinion, and price-match plus 10–25%.
Insert or new build
An insert reuses an existing fireplace opening, so it's the faster, lower-cost route — ideal for upgrading an old, inefficient firebox to a modern, efficient unit. A new build creates a fireplace where there wasn't one, which adds framing, venting, and finishing work. Which one fits depends on whether you already have an opening and how you want the finished fireplace to look.
What installation involves in the Puget Sound
A fireplace put in here has to vent correctly and keep our weather out. That means the right venting for the unit, correct clearances, proper flashing where any flue meets the roof, and finishing that suits your room. Many older Seattle and Tacoma homes have an inefficient open firebox that loses more heat than it makes; a modern insert or a well-built new fireplace turns that into a real heat source for our long, damp season.
How to get an honest installation quote
A real installation quote comes after someone looks at your space, the venting path, and the framing — not from a flat number. Ask whether a $2,000–$3,500 insert into your existing opening will do the job before committing to a $3,500–$5,000 new build. A good installer matches the unit to your home and spells out venting and finishing in writing. If another company quoted a full build where an insert would do, take our free second opinion — quotes are free and in writing with price-match plus 10–25%.
