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 Lansdale Owner’s Guide
Olympia Chimney flue liner replacement in Lansdale typically runs $2,800-$4,200 installed for a standard single-flue stainless steel system, and we stock the common Olympia Chimney diameters on our trucks. Most replacements are completed in one day. You’ll know the liner’s failing when you see rust flakes in the firebox, smell smoke in upstairs rooms during a fire, or your sweep shows you gaps or separation on the camera scan.
We’ve replaced Olympia Chimney liners across Lansdale, from the older colonials near the Merrick Road corridor to newer builds off Valley Forge Road. The pattern we see: homeowners call thinking they need a full chimney rebuild, and what they actually need is a liner that was never properly sized for the appliance venting into it. The camera doesn’t guess. Neither do we.
Which Olympia Chimney Models This Applies To
Olympia Chimney manufactured several liner series that remain in service across Montgomery County. The most common we encounter are the Olympia 316Ti flexible stainless liners (the orange-jacketed 3-ply titanium-stabilized series), the earlier 304 stainless corrugated models (typically 2005-2015 installs), and the rigid Olympia SmoothWall system used primarily for gas appliance venting.
To identify your liner, check the termination cap for an embossed stamp, or have your sweep lower a camera. The 316Ti series carries a part number prefix of OL-316 followed by diameter and length; 304 models use OL-304. The critical compatibility gotcha: Olympia’s 316Ti connectors and top plates are proprietary thread patterns. Generic 316Ti will mate poorly, creating a leak path at the collar. We source OEM Olympia termination hardware through our Haven buying network, or match with DuraFlex and Gelco equivalents that we’ve verified thread-compatible.
Aftermarket liners from DuraFlex and HeatShield meet or exceed Olympia’s 316Ti spec at lower material cost. We specify which we’re proposing, and why, in your written estimate.
Signs Your Olympia Chimney Flue Liner Replacement Is Failing

- Rust-colored granules or flakes collecting in the firebox. This indicates the inner 316Ti ply has cracked, allowing combustion moisture to reach the carbon steel outer layer. In Lansdale’s freeze-thaw cycles, that rust accelerates from surface staining to through-wall failure faster than in milder climates.
- Smoke odor in second-floor bedrooms or attic space during fireplace use. A separated liner joint or corroded hole is venting flue gases into the chimney cavity. Carbon monoxide can migrate through framing gaps before you ever see smoke.
- White efflorescence blooming on exterior brick below the roofline. Combustion gases condensing in a compromised liner deposit acidic moisture against the masonry. The salt leaching out is your chimney’s slow dissolution becoming visible.
- The sweep’s camera shows a “shingled” or fish-scale pattern on the liner wall. This is metal fatigue from thermal cycling, each scale a stress crack waiting to open. On Olympia 304 models in heavy-use Lansdale homes, we typically see this at 12-18 years of service.
- Your appliance backdrafts on windy days or when the furnace kicks on. A liner that’s lost structural integrity can no longer maintain proper draft. The negative pressure from your HVAC system overwhelms a flue that’s essentially leaking its pull to the attic.

AfterReplacement Cost & What’s Included
| Scope | Price Range |
|---|---|
| Olympia 316Ti flexible liner, single flue, standard height (up to 25 ft) | $2,800 - $3,600 |
| Olympia 316Ti with proprietary top plate and wind directional cap | $3,200 - $4,000 |
| Multi-flue or height over 35 ft, scaffolding required | $4,000 - $5,500 |
| Smoke chamber parging (if needed for proper connection) | $600 - $1,200 add |
What drives the range: liner diameter (6″ vs. 8″ vs. custom oval), height to termination, whether the existing top plate is salvageable, and smoke chamber condition. Every estimate we write in Lansdale includes the specific liner spec, the warranty term, and the camera documentation you’ll receive under Haven Standard Clause 4. No surprises after we start.
DIY or Call Us?

Here’s what you can safely check yourself: verify the model stamp on your termination cap, measure approximate flue height with a tape from roof to hearth, and confirm your appliance’s BTU input and required liner diameter from the manufacturer plate.
Here’s where DIY goes wrong, and why we don’t recommend it: pulling a liner requires working on a steep roof with a heavy, flexible load that can snag on a hidden obstruction and transfer fall force unpredictably. More critically, an improperly seated top plate or missing seal at the thimble creates a carbon monoxide path you won’t detect until symptoms appear. We’ve been called to Lansdale homes where a homeowner’s self-installed liner had a 3/8″ gap at the collar, venting into the bedroom wall cavity for two heating seasons.

FAQs
A properly installed 316Ti liner typically lasts 20-25 years in Lansdale’s climate, though heavy wood-burning with soft fuel can cut that to 12-15. The 304 series more commonly needs attention at 15-18 years. Annual camera inspection catches deterioration before it becomes a safety issue. Call (267) 327-4785 to schedule - estimates are free.
Localized cracks in an otherwise sound 316Ti liner can sometimes be addressed with HeatShield cerfractory sealant, but only if the camera shows the damage is superficial and confined. Separation at joints, through-wall corrosion, or fish-scale fatigue pattern means replacement. We show you the camera footage and explain which category you’re in before quoting either path. Call (267) 327-4785 for a free second opinion on any written estimate.
Most Olympia Chimney liner replacements in Lansdale are completed in a single day, 6-8 hours for a standard single-flue job. Two-story homes with complex roof access or multi-flue systems may extend to a second day. We text you when the technician is en route and update you if scope changes. Call (267) 327-4785 to book.
We stock the common Lansdale diameters - 6″, 7″, and 8″ round in 316Ti flexible - and carry DuraFlex and Gelco equivalents for same-day availability on most jobs. Custom diameters or rigid SmoothWall systems are typically next-day from our supplier. We’ll confirm stock when you call (267) 327-4785.
Corrine Halstead grew up in Queens and learned early that old buildings keep secrets, most of them in the flue. She trained in building systems and HVAC technology at New York City College of Technology before spending the better part of two decades doing chimney work across Montgomery County. Her crew has serviced wood-burners and gas inserts throughout Lansdale, including older colonials near the Merrick Road corridor, where creosote buildup is rarely a surprise but always worth showing the homeowner on camera.
If you’re seeing rust flakes, smelling smoke where you shouldn’t, or staring at a competitor’s estimate you don’t fully understand, call us. We’ll run the camera, write the price, and let the footage do the talking. No work starts without a written scope, written warranty, and your signed approval - that’s Haven Standard Clause 1, and it’s how we’ve operated since 2009.
