Olympia Chimney Flue Liner Replacement in Los Angeles, CA

Olympia Chimney Flue Liner Replacement: The Los Angeles Owner’s Guide

We stock and install Olympia Chimney-compatible flue liner replacement in Los Angeles, with most jobs running $2,800 to $4,500 installed depending on height, diameter, and access. Same-day replacement is available when we have your diameter in stock, which we do for the common Olympia 6-inch and 8-inch round liners that fit most Los Angeles masonry fireplaces built between 1940 and 1980. Homeowners usually discover the problem during a sweep when our camera finds gaps, or when they notice mortar crumbs in the firebox and a faint smoke smell upstairs on still days.

Which Olympia Chimney Models This Applies To

Olympia Chimney manufactured several liner series, and matching the right replacement means reading the collar stamp or measuring the existing liner’s outer diameter with the insulation jacket intact. The Olympia 316Ti flexible liner, common in Los Angeles hillside homes with offset flues, carries a part number prefix of “OLY-F” followed by the diameter and length code. The rigid Olympia 304 series, found more often in flat-roof Mid-Century ranches from Van Nuys to the Foothills, uses a twist-lock collar system that is not interchangeable with flex-to-rigid adapters from other brands.

We carry both OEM Olympia replacement sections and compatible DuraFlex equivalents. For most Los Angeles installations, the DuraFlex 316Ti matches the Olympia spec exactly, same alloy, same 0.006-inch wall thickness, and carries the same UL 1777 listing. The only place we insist on OEM Olympia is when we’re tying into an existing Olympia rigid tee that has the proprietary twist-lock geometry. We’ve learned that lesson the hard way on a job in Highland Park where an aftermarket tee leaked at the joint for three weeks before we pulled it and started over. Gil Mercer won’t sign off on a liner that doesn’t mate clean.

Signs Your Olympia Chimney Flue Liner Replacement Is Failing

• Mortar debris in the firebox. When the terra cotta flue liner behind your Olympia stainless liner cracks, pieces fall to the hearth. We see this most in Los Angeles homes near the coast where salt air accelerates corrosion at the liner collar.
• Smoke drafting back on startup. A separated Olympia flex liner, especially at an elbow in a two-story flue, creates a gap that kills draft. The smoke has to go somewhere, and it follows the path of least resistance into your living room.
• White efflorescence on the exterior brick. Moisture getting past a compromised Olympia liner carries dissolved salts through the masonry. In Los Angeles, this shows up after winter rains when homeowners fire up the hearth for the first time in November.
• Hot exterior walls near the chimney chase. An Olympia liner with a torn insulation jacket loses its zero-clearance rating. We measured 180°F on a stucco chase in Eagle Rock last February where the liner jacket had worn through at a support band.
• Condensation stains on the ceiling below the firebox. A perforated Olympia flex liner allows combustion gases to cool and condense in the smoke chamber. The water runs down and finds the nearest drywall seam.

Replacement Cost & What’s Included

What drives the range: height of the flue, number of offsets, whether we need to remove an existing damaged liner first, and if the top plate or rain cap needs replacement. We price every job upfront after inspection, not after we’re halfway up the ladder. The number on the estimate is the number on the invoice. Our 90-Day Done Right Promise covers the liner installation in writing, no arguing, if it’s not right we come back.

DIY or Call Us?

An owner can safely check three things from the ground: confirm the part number on the Olympia collar stamp if it’s accessible, measure the firebox opening to confirm flue diameter, and look for visible gaps at the top of the chimney with binoculars. What you should not attempt is pulling a liner yourself. The work involves working at height on a pitched roof, handling sharp stainless edges, and properly sizing support bands and insulation wrap to maintain UL-listed clearances. A liner that settles even two inches creates a gap at the collar that can leak carbon monoxide into wall cavities.

We’ve rescued three DIY liner jobs in Los Angeles this past year alone. One in Silver Lake had the flex installed upside-down, smooth side in, which collected creosote in the corrugations. The chimney doesn’t lie. Neither do I. Call (844) 418-0954 and we’ll send a technician with the right Olympia-compatible diameter on the truck.
