Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Olympia Chimney Flue Liner Replacement: The Denver Owner’s Guide
We stock and install Olympia Chimney-compatible flue liner replacement in Denver, with typical installed pricing running $2,800-$5,400 depending on height, diameter, and whether the existing liner pulls clean or has to be cut out. Most Olympia Chimney liner jobs we book in Denver are completed in a single day once the written scope is approved. Homeowners usually discover the problem during a routine sweep when the camera reveals cracked terracotta, a corroded stainless flex, or gaps at the collar where the liner meets the appliance adapter.
Which Olympia Chimney Models This Applies To
Olympia Chimney manufactures several liner series, and matching the right replacement means reading what’s left of the original label or measuring the flue collar precisely. We regularly replace liners in Olympia’s 316Ti flexible stainless series, their 304 alloy economy lines, and the older AL29-4C condensing-rated systems found in High Efficiency gas installations around Stapleton and Lowry. The collar diameter, flex length, and whether the original was a top-down or bottom-up termination determine which replacement sleeve fits without field modification.
OEM Olympia liners ship with matched appliance adapters and termination caps, but we also source quality aftermarket equivalents through our Haven buying network when the original series has been discontinued. The aftermarket decision usually comes down to warranty length: Olympia’s OEM carries a lifetime limited warranty on 316Ti, while the aftermarket equivalents we stock from DuraFlex and Gelco run 20-year or lifetime depending on alloy grade. We write both options on the estimate and let the footage decide. If your original label is gone, we measure the flue opening, check the appliance BTU rating, and match alloy to fuel type - never guess.
Signs Your Olympia Chimney Flue Liner Replacement Is Failing

- White or orange powder on the liner walls. This is chloride corrosion attacking the stainless steel, common in Denver’s freeze-thaw cycles where condensation sits in the flue. The metal thins from the inside out, and the camera picks it up before you smell anything wrong.
- Chunks of clay in the firebox. If you have an original terracotta flue behind an Olympia retrofit liner, spalling clay means the old liner is collapsing onto the new one. The flex liner gets crushed or displaced, and draft drops fast.
- Smoke or CO detectors triggering during shoulder season. A separated liner collar or gap at the appliance adapter lets combustion spill into the smoke chamber. In Denver’s altitude, where draft is already thinner, even a small gap becomes a venting failure.
- Water staining on the chimney breast in summer. The liner’s top termination seal has cracked or the flex has pulled away from the crown. Summer thunderstorms in the Front Range drive water straight down an open flue, and the liner rusts from the top.
- The sweep can’t get the camera past a certain point. A collapsed section, heavy creosote buildup behind a liner gap, or a liner that has inverted on itself blocks the camera. We mark the footage, show you the obstruction, and explain whether it’s a spot repair or full pull-and-replace.

|---|---|
| Olympia 316Ti flex liner, standard ranch height (18-22 ft) | $2,800-$3,600 |

| AL29-4C condensing liner (High Efficiency gas) | $3,800-$5,400 |
| Removal of failed liner + disposal | Included above |

What drives the range: height adds material and rigging time; steep roofs in neighborhoods like Berkeley or Sunnyside require additional safety setup; and if the existing liner is corroded through in multiple spots, we pull it in sections rather than risking wall damage. Every estimate we write in Denver lists the exact liner alloy, diameter, length, and termination type before work starts - Haven Standard Clause 1. The 365-Day Done Right Promise covers the installation, and the liner manufacturer’s warranty covers the material. We source through our Haven buying network specifically to keep customer prices honest, and we stock common Olympia-compatible diameters on our trucks.
DIY or Call Us?

An owner can safely check three things: whether the termination cap is present and seated, whether water is entering from above, and whether the appliance adapter collar is still hand-tight. Beyond that, flue liner replacement involves working at height on a pitched roof, handling sharp stainless edges, and sealing combustion joints that must hold under negative pressure. A liner that terminates even slightly off-plumb can reverse draft in Denver’s thin air, pulling CO into the living space instead of exhausting it. We don’t recommend owner installation. The camera doesn’t guess. Neither do we. Call (720) 674-7312 and we’ll scope it, write the price, and book the work when you’re ready.
FAQs
A 316Ti stainless liner properly sized and installed should last 15-25 years in Denver, though we’ve replaced 304 alloy liners in as little as 8 years when condensation was chronic. The freeze-thaw cycling and occasional hail impact on termination caps shorten life compared to milder climates. Call (720) 674-7312 for an exact quote - estimates are free.
Spot repairs work for isolated cracks or small gaps at the collar, which we can address with a stainless repair sleeve or a new adapter. If the camera shows corrosion over more than 30% of the run length, or if the flex has inverted or collapsed, replacement is the only code-compliant fix. Call (720) 674-7312 for an exact quote - estimates are free.
Most Olympia liner replacements we complete in Denver take 4-6 hours from ladder set to final camera verification. Two-story homes, tight flues, or liners that have to be cut out in sections add time, but we still finish same day in nearly every case. Call (720) 674-7312 for an exact quote - estimates are free.
We carry the most common diameters and lengths for Olympia-compatible 316Ti and AL29-4C systems on our Denver trucks, sourced through our Haven buying network alongside DuraFlex, HeatShield, and Gelco equivalents. If your flue is an unusual size, we order overnight and book installation the next business day. Call (720) 674-7312 for an exact quote - estimates are free.
Level Two Chimney Denver is an independent service provider and is not affiliated with Olympia Chimney. We install Olympia-compatible liners and equivalents from DuraFlex, HeatShield, Gelco, Famco, and Copperfield.
Ready to see what your flue actually looks like? Call (720) 674-7312. We’ll send a background-checked, uniformed technician with a camera, a written price before any work starts, and a photo record when it’s done - Clause 4 of the Haven Standard, same as we’ve done since 2009.
