Olympia Chimney Flue Liner Replacement Nationwide

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

We stock and install Olympia Chimney-compatible flue liner replacement in Evanston, typically running $2,800-$5,200 installed depending on flue height, diameter, and whether the chase top needs rework. Most Olympia Chimney liner jobs we book in Evanston are completed in a single day, with the new liner sized from our on-truck inventory of DuraFlex, HeatShield, and Olympia Chimney spec materials. Homeowners usually discover the problem during a routine sweep when the camera reveals cracked terracotta, gaps at the mortar joints, or corrosion pinholing through a stainless liner that was never the right alloy for Illinois freeze-thaw cycling.

Which Olympia Chimney Models This Applies To

Olympia Chimney manufactures UL-listed stainless steel chimney liners in 304 and 316Ti alloys, with the 316Ti grade specified for oil and wood-burning applications where condensate is aggressive. The critical compatibility gotcha in Evanston’s housing stock: Olympia’s standard round liners are stocked in 5.5-inch, 6-inch, and 8-inch diameters, but many of the 1920s masonry chimneys near the lakefront historic district were built with 8×8 or 8×12 terracotta flue tiles that require an ovalizing kit or a custom-fabricated transition. We measure the existing flue with a laser caliper before quoting, not after we’ve torn out your firebox.

To identify your current liner, look for the Olympia Chimney stamp on the top termination cap or the collar plate where the liner exits the crown. If the stamp reads “OLY-316Ti” followed by a diameter code, you’ve got the higher-grade alloy. If it’s unmarked or stamped with a generic “304,” we need to verify whether the original installer matched the alloy to your fuel type. We source replacement liners through Haven’s buying network, which includes both OEM Olympia Chimney product and Gelco equivalent spec, and we’ll show you both options with the price difference in writing before you decide.

Signs Your Olympia Chimney Flue Liner Replacement Is Failing

• White efflorescence or rust staining on the exterior brick. This means moisture is getting past the liner and condensing in the masonry. In Evanston, where lake-effect humidity sits heavy from October through April, that moisture freezes, expands, and spalls the brick face. We see this most often on south-facing stacks that get sun-thaw cycles daily.
• Flakes of terracotta in the firebox or cleanout door. The original clay liner is delaminating. Once the inner surface starts shedding, the liner’s insulation value drops and creosote adhesion increases. On a recent job near Dempster Street, we pulled two gallons of terracotta shards before the camera could even pass.
• Smoke or odor seeping into upstairs rooms during a fire. This indicates a breach in the liner allowing combustion gases into the chimney cavity. Carbon monoxide can follow the same path. The camera doesn’t negotiate - and neither does creosote.
• Visible gaps or separations in a stainless liner when viewed from the top. Thermal expansion and the weight of accumulated creosote can pull joint connections apart. Olympia’s twist-lock couplings are reliable, but if the original installer skipped the locking bands or used the wrong sealant, the joint fails in year three, not year twenty.
• Your sweep recommends replacement but can’t show you the damage. This is not a symptom of the liner; it’s a symptom of the inspection. We include camera footage on every visit under Haven Standard Clause 4. If someone told you the liner is bad and handed you a flashlight sketch, call us for a second opinion at no charge.

Replacement Cost & What’s Included

The range depends on three factors we measure, not estimate: flue length from appliance to termination, the number of offsets or bends, and whether the existing top needs resealing or full replacement. Every quote is delivered in writing before work starts - Haven Standard Clause 1, no exceptions. The installed liner carries a lifetime warranty on the material and our 365-Day Done Right Promise on the workmanship. Corrine Halstead and her crew have been documenting every Evanston liner job with photos and camera footage since 2009, and that archive is yours on completion.

DIY or Call Us?

There’s a safe middle ground and a hard stop. An owner can verify the liner stamp from the roof or top termination with a flashlight and binoculars, and you can check the cleanout door for terracotta debris without risk. What you cannot safely do: drop a new liner down a two-story flue, connect it to an appliance collar with proper clearances, or seal a crown penetration against water intrusion. The liner arrives as a coil of sharp stainless ribbon, the insulation wrap requires two people to tension correctly, and the top termination must be counterflashed to the crown or you’ll have a leak in the first hard rain. We’ve been called to three Evanston jobs in the past two years where a homeowner got the liner hung but couldn’t get the appliance connection sealed, and in two of those cases, the unsealed joint had been venting into the home for weeks. Call (708) 234-1174 and we’ll quote it in writing before we start.
