Olympia Chimney Flue Liner Replacement Nationwide

Olympia Chimney Flue Liner Replacement: The Bellevue Owner’s Guide

We stock and install Olympia Chimney-compatible flue liner replacement in Bellevue, with typical installed pricing running $2,800-$4,500 for a standard single-flue system and most jobs completed within one working day. Corrine Halstead and our crew carry Olympia Chimney liner inventory on the truck for common diameters, so we’re not ordering blind and making you wait. Most Bellevue owners discover their liner has failed when water starts weeping through the chimney breast during our wet winters, or when a routine sweep pulls back clay fragments instead of soot.

Which Olympia Chimney Models This Applies To

Olympia Chimney manufactures stainless steel flexible liners in 316Ti and AL29-4C alloys, with the AL29-4C spec required for any condensing appliance or high-efficiency gas insert. The critical compatibility gotcha in Bellevue: older Olympia Chimney systems installed before 2018 often used 316Ti across the board, and that alloy will not survive the acidic condensate from a modern 90%-plus furnace or water heater vented into the same flue. We see this mismatch regularly in Lakemont and West Bellevue homes where the HVAC was upgraded but the liner was not.

To identify your exact part, check the stamped band near the top termination for the alloy grade and diameter. Olympia Chimney labels run 3 to 8 inches in half-inch increments, with 5.5-inch and 6-inch being the most common residential sizes in King County. If the stamp is corroded off, we measure the inner flue dimension directly and match to the Olympia Chimney spec sheet. We also stock quality aftermarket equivalents from DuraFlex and HeatShield through our Haven buying network when the OEM lead time stretches past what your heating season allows. The choice is yours, and we quote both before any work starts.

Signs Your Olympia Chimney Flue Liner Replacement Is Failing

• Water staining on interior walls near the chimney chase. A compromised Olympia Chimney liner loses its ability to contain combustion moisture, and that moisture migrates through mortar joints into drywall. In Bellevue’s 38-inch average annual rainfall, this accelerates quickly once the liner seal breaks down.
• Clay or metal flakes in the firebox or cleanout. These fragments are pieces of the original terracotta liner or degraded stainless segments shedding into the flue path. They signal structural failure, not surface corrosion, and they will continue to fall until the liner is replaced.
• Strong smoke odor when the system is not in use. A liner with gaps or separations allows downdrafts to pull creosote odor into living spaces. This is especially noticeable in Bellevue’s pressure-wind corridor near Lake Washington, where seasonal air movement is pronounced.
• Visible gaps or waviness in the liner wall during inspection. Our camera scan reveals these directly: sections of Olympia Chimney liner that have lost structural integrity show as bulges, seams pulling apart, or circumferential cracking at stress points where the liner bends to meet the thimble.
• Carbon monoxide detector alerts with no obvious source. A perforated liner can leak combustion gases into wall cavities before they ever reach the cap. This is not a sensor malfunction; it is a liner failure requiring immediate professional evaluation.

Replacement Cost & What’s Included

What drives the range: flue height, number of offsets, whether the existing top plate and connector are salvageable, and whether we find hidden damage in the smoke chamber or firebox that needs addressing before the new liner drops. We deliver a written price, written scope, and written warranty before anyone starts - Clause 1 of the Haven Standard. Every Olympia Chimney liner we install carries a lifetime warranty on materials and our 365-Day Done Right Promise on workmanship. The photo record, archived under Haven Standard Clause 4, documents the full flue condition before and after.

DIY or Call Us?

There is exactly one safe owner check: shine a flashlight up the flue from the firebox and look for visible debris, staining, or daylight where the liner should be continuous. Do not attempt to drop a replacement liner yourself. The work involves working at height on a steep roof, handling sharp stainless edges, and properly sizing and securing the top termination to withstand Bellevue’s wind loads. A liner that is not fully seated and sealed at the top will leak combustion gases and void any manufacturer warranty. The camera doesn’t guess. Neither do I. Call (425) 696-0387 and we’ll scope it properly, quote it in writing, and handle the installation with background-checked, uniformed technicians who text when they’re on the way.
