Olympia Chimney Flue Liner Replacement Nationwide

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

Olympia Chimney flue liner replacement in Littleton typically runs $2,800-$4,500 installed, depending on flue diameter, height, and whether the existing liner is stainless steel or terracotta. We stock Olympia Chimney-compatible stainless liners in 6″, 7″, and 8″ diameters on our Littleton trucks, and most replacements are completed in a single day. Corrine Halstead and our crew have pulled failed Olympia liners from homes across Columbine Knolls, Ken Caryl, and the older ranch neighborhoods north of Downtown Littleton where these systems were common in 1980s-2000s builds.

Most owners find out their liner is shot during a routine sweep or when they spot water staining on the chimney breast, a faint smoke smell in upstairs rooms, or a home inspector flags “deteriorated flue liner” on a sale report. The camera tells the rest.

Which Olympia Chimney Models This Applies To

Olympia Chimney manufactured several liner series that found their way into Littleton homes, primarily through regional distributors in the 1990s and 2000s. The most common we encounter are the Olympia stainless flexible liners in 316Ti alloy (the residential standard) and the heavier 316L rigid sections used in some commercial-adjacent installs. Check the collar plate at the top of your flue, or the metal tag left by the original installer - Olympia stamped model prefixes like “OLY-FLX” or “OLY-RGD” with diameter and length codes.

Here’s the compatibility gotcha: Olympia’s flexible liners were sold in two wall thicknesses, .006″ and heavier .012″, and the collar fittings are not interchangeable. We measure this with a bore gauge during our camera inspection, because ordering the wrong spec means a second trip and a second day of scaffolding.

On OEM versus aftermarket: Olympia Chimney as a brand has limited direct distribution in Colorado now, so we source equivalent 316Ti flexible liners through our Haven buying network from DuraFlex and Gelco, spec-matched to Olympia’s original dimensions. The alloy grade matters more than the name stamped on the box. For homeowners who want the Olympia-branded replacement, we can special-order through our distributor, though lead time runs 2-3 weeks and the price jumps roughly 20% for the same metal.

Signs Your Olympia Chimney Flue Liner Replacement Is Failing

• Water stains on interior walls near the chimney stack. A cracked or separated Olympia liner lets combustion moisture and exterior rainwater migrate through gaps in the terracotta or the liner joints, showing up as yellow-brown patches on drywall. In Littleton’s freeze-thaw cycle, this accelerates every spring.
• Smoke odor in upstairs bedrooms or attic space. When the liner fails at a joint or corrodes through, flue gases seep into the chimney cavity and find paths into conditioned space through framing gaps. The smell is often worse on windy days when pressure differentials shift.
• Flakes of terracotta in the firebox or cleanout door. If your original liner was terracotta tile and the Olympia stainless was never installed, spalling clay is a red flag. Even with a stainless liner in place, terracotta debris means the outer shell is deteriorating and may be compromising the liner’s support.
• Visible gaps or rust streaks during a rooftop inspection. The Olympia collar and top plate are galvanized steel on most models; after 15-20 years of Front Range sun and snow, the galvanizing fails and the plate rusts through. Water then runs down the liner exterior, causing exterior staining and interior corrosion.
• Your sweep’s camera shows orange peel texture or pinholes in the liner wall. This is advanced corrosion from acidic condensation, common in Littleton homes where owners burn unseasoned wood or run gas inserts in liners sized for wood fireplaces. The camera doesn’t have an opinion - it just shows you what’s there.

Replacement Cost & What’s Included

What drives the range: flue height from roofline to firebox, whether we need to remove an existing failed liner first (common with collapsed flexible liners), roof pitch and access, and whether the smoke chamber needs parging before the new liner drops. Every quote is written, itemized, and signed before work starts - Haven Standard Clause 1. The price includes the NFPA 211 Level 2 camera inspection, the documented photo record under Clause 4, and our 365-Day Done Right Promise on the installation. Materials carry a lifetime limited warranty through our suppliers; our labor warranty is written on the same page.

DIY or Call Us?

There’s a safe middle ground here, and then there’s where DIY ends.

What you can check: look up your flue from the firebox with a flashlight for visible gaps or debris. Check the exterior top plate for rust streaks. Verify your model from any installer tag. These observations help us prep, but they don’t replace a camera scan.

Where DIY goes wrong: dropping a liner is not like replacing a dryer vent. The liner arrives coiled and must be measured, cut, and connected to an insulated top plate with proper clearance to combustibles - a specification that changes based on your chimney’s construction type. More critically, working on a Littleton roof in winter, or on a two-story pitch common in Columbine Valley, is genuinely dangerous without proper fall protection and experience. We’ve been called to extract homeowner-installed liners that were the wrong diameter, uninsulated where code required insulation, or dropped without a proper bottom connector, creating a new fire hazard.

We’re not affiliated with Olympia Chimney - we’re an independent service provider - and we’ll tell you honestly if your liner has useful life left. Call (720) 439-4666 for a written estimate; the inspection and quote are free, and we’ll show you the camera footage before any paperwork.
