Olympia Chimney Flue Liner Replacement Nationwide

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

Olympia Chimney flue liner replacement in Ewing typically runs $1,800 to $3,400 installed, depending on chimney height, diameter, and whether the chase needs rework. We stock Olympia Chimney-compatible alloy and stainless liners in common Ewing sizes - 6-inch and 8-inch round, plus several oval configurations for older masonry - and most replacements are completed in a single visit. Most Ewing homeowners discover the problem during a pre-winter sweep when our camera shows gaps, spalling, or orange rust blooming through a thinning wall.

Which Olympia Chimney Models This Applies To

Olympia Chimney built several liner series over the years, and the right replacement depends on what is currently in your flue. The 304-alloy flex liners from the early 2000s are common in Ewing’s split-level and ranch homes, while the heavier 316Ti stainless systems came later for oil and gas conversions. Check the collar plate at the top of the chimney - Olympia stamped model numbers there, though rust often obscures them after fifteen New Jersey winters.

We carry OEM-spec Olympia Chimney replacement liners and compatible aftermarket equivalents from DuraFlex and Gelco. For most Ewing installations, a quality aftermarket 316Ti stainless liner matches or exceeds the original alloy at a lower parts cost. The exception is certain factory-built fireplace systems where the listing requires exact OEM clearances - we verify that against the installation manual before ordering. Hearthstone Chimney Co. is an independent service provider, not affiliated with Olympia Chimney.

One compatibility gotcha we see in Ewing: Olympia’s 6-inch oval-to-round adapters from the 1990s used a slightly different offset than current production. Measuring the existing top plate before ordering saves a return trip.

Signs Your Olympia Chimney Flue Liner Replacement Is Failing

• Orange rust flakes in the firebox or cleanout. This means moisture has breached the liner’s protective oxide layer. In Ewing, freeze-thaw cycles accelerate the damage once water finds a gap, and what starts as surface corrosion becomes a pinhole leak within a season or two.
• White efflorescence on exterior brick or staining inside the firebox. Condensation is traveling through liner gaps and depositing salts. We see this especially in Ewing homes with newer high-efficiency appliances connected to older, undersized Olympia liners that never ran cool enough to condense before.
• Smoke odor when the furnace or water heater runs. A cracked or separated liner is allowing exhaust to leak into the chimney cavity. This is not a nuisance - it is a carbon monoxide pathway into wall voids and living spaces.
• Chunks of clay tile in the cleanout, with a metal liner visible above. The original clay liner has collapsed, and the Olympia metal liner was likely installed as a retrofit that is now itself failing. The clay debris blocks proper draft and creates a fire hazard.
• Visible gaps or waviness in the liner wall on camera inspection. Our camera shows separation at joints, dents from falling debris, or thinning metal that appears translucent under light. If the flue is right, the fire takes care of itself - but a distorted liner never drafts correctly.

Replacement Cost & What’s Included

What drives the range: chimney height from roofline to top, whether the existing liner pulls out cleanly or is cemented in place, and if the top plate and rain cap need replacement. Our estimate includes the Level-2 camera inspection, photos you can see, removal and disposal of the old liner, installation of the new system with proper insulation and listing compliance, and a plain-English verdict on anything else we found. The 90-Day Done Right Promise covers the work in writing, no arguing. We also apply our standing $50 off any repair over $250, and Ewing seniors and veterans receive an automatic 5% discount.

DIY or Call Us?

There is nothing wrong with looking. You can shine a flashlight up the flue from the firebox and check for obvious rust, gaps at joints, or debris. But pulling and replacing a flue liner involves working on a steep roof with heavy, flexible material that wants to kink or tear if mishandled. The stainless edges are sharp enough to need leather gloves, and a dropped section can damage shingles or guttering.

More critically, the liner must be sized to the appliance using NFPA 211 tables, insulated correctly for solid fuel, and terminated with proper clearances to combustibles. Get any of that wrong and the chimney is less safe than when you started. We have found DIY liner jobs in Ewing where the homeowner used the wrong alloy for oil exhaust, voiding the warranty and corroding through in four years. Call (856) 388-5580 and we will give you a straight answer on whether this is a job for your situation or ours.
