Olympia Chimney Flue Liner Replacement: The Houston Owner’s Guide
Olympia Chimney flue liner replacement in Houston typically runs $1,800-$3,400 installed, depending on chimney height, diameter, and whether we’re working with a straight run or an offset. We stock Olympia Chimney-compatible liners in 6″, 7″, and 8″ diameters on our trucks, and most replacements are completed in a single visit. If you’re seeing flakes of clay tile in your firebox or smelling smoke in upstairs rooms, the liner has likely cracked or separated at a joint.
Most Houston homeowners discover the problem during a Level-2 inspection, or when a new gas insert won’t pass pressure testing because the existing liner is compromised. In the Heights, where Dale Hutchins grew up, we’ve pulled out original clay liners from 1920s bungalows that finally gave way after a century of Gulf Coast humidity cycles. A clean flue doesn’t announce itself. That’s the point.
Which Olympia Chimney Models This Applies To
Olympia Chimney manufactures flexible stainless steel liners in the DuraFlex and ProFlex series, plus rigid stainless options for straight chimneys. The critical match is the diameter-to-appliance pairing: wood-burning inserts need 6″ or 7″ depending on BTU output, while open hearth fireplaces often require 8″ or larger. Check the metal tag on your existing liner, usually visible at the top of the chimney or from the cleanout door. The tag lists the UL listing number, diameter, and material grade - 316Ti stainless for wood, 304 for certain gas applications.
We also carry quality aftermarket equivalents from DuraFlex and Gelco that meet the same UL 1777 standard, often at lower cost with identical performance. The gotcha with Olympia Chimney systems: some ProFlex installations from 2008-2014 used a proprietary collar connection at the appliance adapter that isn’t interchangeable with standard flex couplings. We measure this on site before ordering, because guessing wastes a day and leaves you without heat.

Signs Your Olympia Chimney Flue Liner Replacement Is Failing
- Clay debris in the firebox. If you’re sweeping out ceramic shards or sandy grit after fires, the original clay liner is spalling. Houston’s freeze-thaw cycles are mild, but Gulf moisture seeps into hairline cracks, then expands when the flue heats. We see this most in homes near Buffalo Bayou where the water table sits high.
- Smoke smell in upstairs bedrooms or attic. A separated liner joint or cracked section lets combustion gases leak into the chimney cavity. The smoke takes the path of least resistance, which is often through a framed chase into second-floor spaces.
- White efflorescence on exterior brick. That chalky residue means moisture is migrating through the masonry. When a liner fails, condensation from gas appliances or rain intrusion hits the unprotected brick, carrying salts to the surface. In Katy and Sugar Land, we’ve traced this to liner gaps that went undetected for two heating seasons.
- Gas insert fails pressure or spillage testing. Newer direct-vent inserts are unforgiving. If the liner has even a pinhole or loose top connection, the unit shuts down or the CO detector trips. The fix is liner replacement, not another service call on the appliance.
- Visible gaps or corrosion at the top termination. From the roof, you may see the liner collar rusted through, or daylight between the liner and the flue wall. Stainless doesn’t rust easily, but salt air from Galveston Bay accelerates corrosion at the exposed top joint.
Replacement Cost & What’s Included
Here’s how Olympia Chimney flue liner replacement pricing breaks down for Houston homes:
- 6″ flex liner, single-story straight run: $1,800-$2,200
- 7″ flex liner, two-story with offset: $2,400-$2,900
- 8″ rigid or heavy-wall flex, tall chase: $2,800-$3,400
- Appliance adapter and top termination (included): $180-$340 depending on model
- Insulation wrap for NFPA 211 compliance: $220-$380
The range depends on three things: how much demolition we do to access the flue, whether the existing liner is stuck and requires extraction tools, and if the chimney crown needs rebuilding to seal the new top plate. We price this upfront after camera inspection - the number on the estimate is the number on the invoice. Every liner replacement carries our 90-Day Done Right Promise in writing, plus the manufacturer’s 20-year warranty on the material itself.
DIY or Call Us?
There’s a short list of what a homeowner can safely check: confirm the damper opens fully, verify the chimney cap isn’t clogged with leaves, and look down the flue with a flashlight for obvious obstructions. Beyond that, flue liner replacement involves working at height on a roof pitch, handling sharp stainless edges, and ensuring the combustion path is sealed to code. A gap at the appliance adapter or a missing insulation wrap creates a fire path through the framing. We’ve been called to three homes in the past two years where a DIY liner pulled away from the top plate and filled the attic with smoke.
Our technicians carry the pull ropes, cone spreaders, and camera gear to verify the full length after installation. Most jobs finish in four to six hours. Call (877) 516-5603 and we’ll schedule a camera inspection - estimates are free, and we stock the common sizes.
FAQs
How long does an Olympia Chimney flue liner last in Houston?
A properly installed 316Ti stainless liner should last 20-30 years, but we’ve seen premature failure at 12-15 years in homes within five miles of the Ship Channel, where industrial sulfur compounds accelerate metal fatigue. Annual inspection catches the deterioration before it becomes hazardous. Call (877) 516-5603 to schedule - estimates are free.
Can a damaged flue liner be repaired instead of replaced?
Small gaps at the top can sometimes be addressed with a listed repair sleeve, but cracked clay liners and separated flex joints require full replacement to meet NFPA 211. We document the condition with camera photos and give you a plain-English verdict. Call (877) 516-5603 for an inspection - estimates are free.
How long does the replacement take?
Most Olympia Chimney liner replacements are completed in a single visit of four to six hours. Two-story homes with offsets or tight fireplace clearances may run into a second day, but we stock the materials to avoid delays. Call (877) 516-5603 to check same-week availability.
Do you stock Olympia Chimney liners, or is there a wait?
We carry 6″, 7″, and 8″ diameters in 316Ti stainless on our trucks, along with DuraFlex and Gelco equivalents. Specialty sizes or rigid systems for very tall commercial chimneys may need one business day to pull from our Houston warehouse. Call (877) 516-5603 - we’ll confirm fit and availability before we roll.
