Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Olympia Chimney Flue Liner Replacement: The McKinney Owner’s Guide
Olympia Chimney flue liner replacement in McKinney typically runs $2,800-$4,200 installed for a standard single-flue system, with most jobs completed in one day. We stock Olympia Chimney-compatible stainless steel liners in common diameters from 5.5″ to 8″ and carry rigid and flexible options on our trucks for same-day installation when the flue is accessible. Most McKinney homeowners discover the problem during a routine sweep when our camera finds cracked terra cotta, separated joints, or orange staining that signals flue gas leakage behind the liner.
Which Olympia Chimney Models This Applies To
Olympia Chimney produces UL-listed stainless steel liners in the 316Ti and AL29-4C alloy grades, with the 316Ti handling standard wood and gas applications and the AL29-4C required for high-efficiency condensing appliances. The critical compatibility gotcha in McKinney’s older builds, especially the pre-1985 homes near Historic Downtown, is the transition from square or rectangular terra cotta flues to round stainless inserts. An 8″ square flue rarely accepts an 8″ round liner without significant mortar removal or ovalization, and we’ve seen more than one homeowner order a “standard” 6″ liner online only to find it won’t pass the smoke chamber throat.
We source Olympia Chimney liners through Haven’s buying network alongside DuraFlex, HeatShield, and Gelco equivalents. For most McKinney installations, we match the alloy grade to the appliance type, not the brand stamp, and we verify the fit with a pre-installation camera pull before any material gets unboxed. The label on your existing liner, if visible from the top or cleanout, will show the alloy grade and diameter. If the label’s burned off, we measure the flue ID with a chimney ruler and check the appliance BTU output against the liner’s temperature rating. That’s Clause 1 of the Haven Standard: written scope and price before work starts, based on actual measurements, not guesswork.
Signs Your Olympia Chimney Flue Liner Replacement Is Failing

- Orange or brown staining on exterior masonry. This indicates flue gases condensing and migrating through cracks in the terra cotta or gaps at liner joints. In McKinney’s clay-heavy soils, the freeze-thaw cycles of our brief but sharp winters accelerate the mortar deterioration that lets these gases escape.
- Flakes of terra cotta in the firebox or cleanout. Spalling clay liner tiles are a progressive failure. Once the inner surface begins shedding, the liner’s insulation value drops and the outer shell takes direct heat stress. We regularly find this in homes near Adriatica Village where hard water mineral content seems to accelerate clay degradation.
- Strong smoke odor when the fireplace isn’t in use. A separated liner joint or missing section allows downdrafts to pull creosote odor into living spaces. This often worsens on McKinney’s high-pressure bluebird days following a cold front.
- Visible cracks or gaps in the liner when viewed from below with a flashlight. Any crack wider than a dime in a terra cotta liner is a code violation under NFPA 211 and requires replacement, not repair. The camera doesn’t lie, and neither does the written quote.
- Carbon monoxide detector alerts near the fireplace. This is the urgent one. A compromised liner can allow CO to enter wall cavities or living spaces through chase gaps. If your detector sounds, stop using the appliance and call for a Level 2 inspection.

| Component | McKinney Price Range |
|---|---|
| Flexible 316Ti liner (5.5″-6.5″ diameter) | $1,400-$2,000 |
| Flexible AL29-4C liner (5.5″-6.5″ diameter) | $1,800-$2,600 |
| Rigid 316Ti liner sections (per 3′ section) | $180-$260 |
| Top plate and rain cap assembly | $280-$420 |
| Labor: removal, installation, insulation pack | $1,200-$1,800 |
| NFPA 211 Level 2 inspection with camera scan | Included |
| Typical total installed | $2,800-$4,200 |
The range depends on flue height, accessibility (steep roof pitches in Craig Ranch add time), whether we’re removing an existing failed liner, and if the smoke chamber needs parging. Every quote is itemized in writing before scheduling. We don’t start work until you have the price, the scope, and the warranty in hand. That’s Haven Standard Clause 1. The 365-Day Done Right Promise covers all liner installations. Materials carry manufacturer warranties from 10 years to lifetime depending on alloy grade.
DIY or Call Us?

There’s a safe middle ground here. A homeowner can verify the liner diameter with a tape measure from the cleanout, check the appliance nameplate for BTU output, and photograph any visible damage for reference. What you cannot safely do: drop a liner down a two-story flue without proper rigging, cut or crimp stainless steel to fit without deforming the seam integrity, or properly insulate the annular space between liner and flue wall. A poorly seated liner creates a new fire path between the insert and surrounding masonry.
We’ve been called to McKinney homes where a DIY installation left a 3-foot gap at the top, uninsulated, with the rain cap caulked on. The fix cost more than our original quote would have. Corrine Halstead and our technicians carry the proper pull rings, cone spreaders, and insulation mix on every truck. Call (469) 429-2623 and we’ll scope it, price it, and schedule it. Free second opinion on any written estimate you already have.
FAQs
A properly installed 316Ti stainless liner typically lasts 15-25 years in McKinney’s climate, with AL29-4C often exceeding 20 years. The limiting factor is usually moisture intrusion from a failed crown or cap, not the liner metal itself. Annual inspection catches crown cracks before they shorten liner life. Call (469) 429-2623 to schedule - estimates are free.
Localized joint gaps or minor spalling can sometimes be addressed with HeatShield cerfractory foam resurfacing, but cracked terra cotta tiles or separated stainless sections require full replacement. We determine this with a camera scan, not a flashlight guess. If resurfacing is viable, we’ll show you the footage and quote both options. Call (469) 429-2623 for an exact quote - estimates are free.
Most Olympia Chimney liner replacements in McKinney are completed in 4-6 hours for a standard single-flue system. Two-flue chimneys or jobs requiring smoke chamber parging may extend to a full day. We schedule morning starts and aim to have your system test-fired before we leave. Call (469) 429-2623 to check availability - estimates are free.
We stock flexible 316Ti and AL29-4C liners in diameters from 5.5″ to 8″ on our McKinney trucks, along with top plates, insulation, and termination caps. Rigid liner sections and less common sizes (4″ pellet, 10″+ fireplace) typically arrive next business day through our Haven network suppliers. Call (469) 429-2623 and we’ll confirm fit and availability - estimates are free.
