Delridge, King County
A new stainless liner for a Delridge chimney starts at $1,900. That figure covers a straightforward full-length run in a single flue; height, bends in the masonry, an oval or oversized clay flue, and the appliance at the bottom all move it up. No liner gets quoted until our camera footage proves the existing flue has to be retired: cracked or missing tiles, gaps at the joints, a flue that was never lined, or a new stove or insert whose maker requires a liner of a specific diameter.

Liners are an age question first, and the valley's buildings span a long stretch of years. Census survey data for the ZIP area that Delridge sits in put roughly 13 percent of units before 1940 and another 21 percent between 1940 and 1959. A clay-tile flue from those decades has been heated and cooled for seventy years or more, and the peninsula's brick stacks took three deep earthquakes between 1949 and 2001. Tiles from that period tend to crack along their length or open at the mortar joints, and either defect lets heat and combustion gases reach the brick around them.
The Western Regional Climate Center's decades-long Seattle-area station summary sets yearly rainfall a little above 38 inches, and the cold months take the lion's share: just over 6 inches in November, close to 6 in both December and January, and well under an inch in July. The center's statewide narrative describes the whole Puget Sound lowland the same way, wet from October into spring.
Inside a chimney that pattern matters because the burning season and the wet season are the same months. Rain that gets past a worn crown or a missing cap meets the flue just when the fire is warming it, and a cracked tile lets that moisture and the acidic condensation from the exhaust soak into the brick behind it. A continuous stainless liner closes those openings from top to bottom.
Every chimney relining we do in Delridge includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowThe other common trigger is a change of appliance. Some owners of older houses convert an open fireplace to an insert, wood or gas, to get usable heat out of it. A modern insert pushes a smaller, cooler stream of exhaust than the open fire the flue was sized for, and sending it up a large masonry flue invites condensation and fast creosote. The fix is a liner of the size the insert's manual names, connected to the insert and capped at the top. On the appliance side, Seattle's mechanical code asks for a UL 1482 listing on any insert, with the label on the unit, and for the maker's own instructions to govern the installation.
A camera run shows the condition of the tile, the size of the flue and any offsets that decide whether a rigid or flexible liner will pass.
Diameter is read off the appliance's own installation manual; the width of the old flue opening never decides it.
Standing at the crown, a technician threads the stainless tube downward, join it to the appliance below, then fit top plate, cap and insulation as required.
Our camera goes back down the new liner, and those images sit next to the earlier ones in your report.
When the Landmarks Preservation Board reviewed the Cettolin House in 2023, its nomination described the surrounding pair of Youngstown blocks: about 75 to 100 single-family houses, a handful from the 1920s and 1930s, most from the 1940s through the 1970s. A house of that generation may have a masonry flue lined with clay tile, and an owner may since have set an insert into the fireplace.
Seattle's 2021 mechanical code sets the terms for that addition. A fireplace insert must be UL 1482 listed and labeled, and it must go in exactly as its manufacturer specifies, and the installation manual usually names the liner diameter the unit needs. We read the manual before we measure the flue, and the liner follows the manual.

Delridge is a valley neighborhood between the two ridges of West Seattle, on Longfellow Creek, with homes of mixed ages, about a fifth of those in its ZIP code area from the 1940s and 1950s and nearly a third built since 2000. We work every part of it — Pigeon Point, Youngstown, Cottage Grove, Puget Ridge, Riverview included.

We do not assume either way. SDCI gets a call about your address and scope before we schedule, and you hear the answer from us.
Often yes. A stainless liner usually runs down inside the existing tile. Where broken pieces or tight offsets block it, some tile may need to be removed first, and the quote says so.
