HeatShield Flue Liner Replacement Nationwide

HeatShield Flue Liner Replacement: The Olympia Owner’s Guide

HeatShield flue liner replacement in Olympia typically runs $2,800-$4,200 installed for a standard single-flue chimney, with most jobs completed in one day. We stock HeatShield-compatible materials through our Haven buying network and can match your existing liner series without a special order. Most Olympia homeowners discover the problem during a routine sweep or after a chimney inspection flags flaking, gaps, or heat damage in the liner wall.

The camera goes in first. Everything else follows from what it finds.

Which HeatShield Models This Applies To

HeatShield produces two distinct liner systems you’ll find in Olympia homes: the Cerfractory Flue Sealant system (a resurfacing compound applied to existing clay tile liners) and the UL Listed Alloy Liners (stainless steel relining pipe). The Cerfractory system is not a standalone liner replacement; it’s a repair coating. If your chimney was relined with HeatShield’s alloy product, you’re looking at 316Ti stainless in diameters from 3″ to 12″ and flexible or rigid configurations depending on the flue path.

Check the metal tag at the top of the flue or the documentation from your original installation. The model prefix tells the story: HS-FLX for flexible, HS-RGD for rigid. We also see a lot of hybrid installs in the older homes near the Capitol Campus, where a rigid section drops through a straight run and flex takes the offset. The critical compatibility gotcha in our wet climate: HeatShield’s alloy liners use a proprietary collar and termination cap geometry. A generic 6″ flexible liner from a big-box supplier won’t seat correctly on the existing top plate, and we’ve seen three Olympia installs this past year where an aftermarket cap created a condensation trap that accelerated corrosion at the weld seam.

We source HeatShield OEM collars and terminations through Haven’s buying network alongside quality equivalents from DuraFlex and Gelco when the application allows. Corrine Halstead makes the call on equivalents case by case, and we document the substitution in writing before any work starts.

Signs Your HeatShield Flue Liner Replacement Is Failing

• White or orange staining on the exterior brick. This means exhaust gases are migrating through gaps in the liner wall, carrying moisture and acids that crystallize as efflorescence. In Olympia’s 40+ inches of annual rainfall, this accelerates freeze-thaw spalling in masonry.
• Flakes of ceramic or metal in the firebox after burning. Cerfractory coating sheds when it’s reached end of life; alloy liners flake at weld seams or corrosion points. Either way, material in the firebox means the liner’s integrity is compromised.
• Smoky odor in the house, especially on humid days. A liner with gaps or separations loses draft efficiency. The South Sound’s marine air layer, thick with moisture from Puget Sound, makes marginal draft worse and pushes smoke into living spaces.
• Visible gaps or light streaming through the liner wall on camera inspection. NFPA 211 calls this an immediate hazard. Gaps mean direct flame contact with combustible framing, and in Olympia’s dense older neighborhoods like Bigelow Highlands, wall cavities are often original wood lath with minimal clearance.
• Carbon monoxide detector alerts during appliance operation. This is the silent failure mode. A compromised liner can vent CO into wall chases or floor joist bays. We treat this as an emergency call and schedule a camera scan the same day.

Replacement Cost & What’s Included

What drives the range: flue length, roof pitch and access, whether the existing top plate and termination can be reused, and if the chimney needs crown repair before the new liner drops. Every quote from Level Two Chimney Olympia includes the written scope, the written price, and the written warranty before work starts, Haven Standard Clause 1. No exceptions. The 365-Day Done Right Promise covers the installation. Materials carry manufacturer warranty through HeatShield or our equivalent supplier.

We include NFPA 211 Level 2 camera inspection, photo documentation, and a written record of findings, Haven Standard Clause 4. This has been our practice since 2009.

DIY or Call Us?

Here’s what you can safely check yourself: verify the model tag at the flue top, measure the flue diameter with a tape, and photograph any visible damage from the firebox looking up with a flashlight. Do not climb the roof to inspect the termination; Olympia’s composite shingles and frequent moss buildup make this genuinely dangerous without proper fall protection.

What goes wrong with DIY liner replacement: improper sizing creates draft problems that show up months later, especially with EPA-certified stoves that need exact flue diameter. Worse, a liner that doesn’t seat fully at the top plate can shift during our freeze-thaw cycles and open a gap at the collar. We’ve been called to three homes this year where a homeowner install seemed fine until the first hard January freeze. The work requires working at height, handling sharp stainless edges, and confirming proper appliance connection. We’re insured, background-checked, and uniformed, license on the page, with a named tech assigned and a text when we’re on the way.

Call (360) 464-2015 for a written estimate. We’ll camera-scan first, show you what we found, and give you the price before any work starts.
