Olympia Chimney Flue Liner Replacement Nationwide

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

Olympia Chimney flue liner replacement in Brentwood typically runs $1,800 to $3,400 installed, depending on the liner diameter, length, and whether we’re dealing with a straight drop or offset flue. We stock Olympia Chimney-compatible liners on the truck, so most replacements happen in a single visit. The way most owners find out they need this work is through a chimney inspection, a failed Level 2 camera scan, or flue tile pieces showing up in the firebox after a hard winter.

Brentwood’s freeze-thaw cycles are rough on masonry chimneys. When the original clay tile liner cracks, spalls, or separates at the joints, the fix isn’t a patch. It’s a properly sized stainless liner dropped through and insulated. Olympia Chimney makes a solid product for this, and we’ve been installing their liners alongside DuraFlex and HeatShield for years. If your liner is failing, the first question isn’t whether to replace it. It’s whether the chimney itself is still sound enough to hold one.

Which Olympia Chimney Models This Applies To

Olympia Chimney flue liners come in diameters from 4 inches up to 12 inches, in both rigid and flexible stainless. Most Brentwood homes with a masonry fireplace or an older furnace vent are looking at 6-inch, 7-inch, or 8-inch flex liner. The Olympia Chimney catalog covers all of those, plus ovalized options for odd flue dimensions that no longer meet code as-is.

Here’s the compatibility gotcha most people don’t know: the liner diameter has to match the appliance, not the old flue tile. A fireplace with an 8×12 clay flue can’t just take any liner that fits the space. The firebox opening and the appliance BTU rating dictate the right size. Too big and the draft goes lazy, creosote builds, and you’re back to square one in three years. Too small and you’re starving the fire for air. Wendell measures everything against the appliance specs before any liner gets ordered.

As for OEM versus aftermarket: for Olympia Chimney fireplaces and stoves, we generally recommend Olympia Chimney-compatible liner from the same manufacturer. It matches the collar dimensions and the listed clearances. That said, DuraFlex and HeatShield make quality equivalents that sometimes fit better in a quirky Brentwood chimney, especially the older capes and colonials over near Brentwood State Park where flues run at odd angles. We’ll show you the difference, explain the price gap, and let you decide. Top Hat Chimney is an independent service provider, not affiliated with Olympia Chimney, so our recommendation is based on what fits and what lasts, not what one brand wants us to push.

Signs Your Olympia Chimney Flue Liner Replacement Is Failing

• Flue tile chips in the firebox or cleanout. This is the one we see most in Brentwood after a cold snap. The outer clay liner spalls under freeze-thaw stress and drops pieces. It means the flue has already lost its seal. The inner liner may still be intact, but the chimney’s structural liner is compromised.
• Visible rust or staining on the chimney exterior or around the fireplace. Stainless liners don’t rust through quickly, but the connectors, caps, and flashing do. Staining often means condensation is running back down the flue, which happens when the liner is oversized or uninsulated.
• A smell like a campfire that lingers for days after you’ve burned. That’s not normal woodsmoke from the firebox. That’s smoke leaking through a liner seam or a compromised joint and working its way into the walls or the room. In a two-story Brentwood colonial, it shows up as a stale smoke smell in upstairs bedrooms first.
• White staining or flaking on the chimney brick face. Efflorescence means water is moving through the masonry. Over time that same water eats at the liner connection points and the mortar crown. Liners don’t fail in a vacuum. The whole chimney tells the story.
• The damper is rusted, warped, or won’t fully open. This is a downstream symptom. When the liner leaks heat and moisture into the chimney chase, the damper is the first metal component to show it. A damper that was smooth five years ago and now grinds is usually a liner issue in progress.

Replacement Cost & What’s Included

In Brentwood, the installed price for an Olympia Chimney flue liner replacement typically falls between $1,800 and $3,400. A straightforward 6-inch flex liner in a single-story ranch with a straight flue lands at the lower end. A two-story colonial with an offset flue, a 7- or 8-inch liner, and the need for insulation and a new cap lands higher.

Every quote from us includes the liner itself, the top plate and cap, the connector at the appliance, insulation where required, full removal of the old damaged liner sections that are loose or obstructing, and a camera scan before and after. The price Wendell gives you on the phone is the price on the invoice. No add-ons for “disposal fees” or “unexpected complications” that were visible before we started. We’ve been doing this since 1999, and the one thing that kills a local business faster than anything is a surprise charge at the door.

Every completed job carries our 90-Day Done Right Promise in writing. If the liner isn’t drafting right, one call brings us back at no charge.

DIY or Call Us?

You can inspect the outside of your chimney for visible brick spalling, rust staining, or efflorescence. You can look in the firebox with a flashlight and check for tile chips or rust on the damper. That’s useful information to have before you call.

What you shouldn’t do is try to drop a liner yourself. A flue liner replacement means working from the roof, handling 20 to 35 feet of stainless flex, properly insulating it, and connecting it at both ends without kinking it. Liners get ruined in about ten seconds when they’re pulled wrong. You’re also up on a steep Brentwood roof with a tool belt and a 30-pound spool of steel. If you miss a step, you’re not paying for a new liner. You’re paying for a hospital visit and a new liner. Call us at (934) 935-3847 and let a sweep who’s been on these roofs since 1999 do the roof part.
