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 Bangor Owner’s Guide
We stock and install Olympia Chimney-compatible flue liner replacement in Bangor, with typical installed pricing running $2,800-$4,500 depending on height, diameter, and whether the chase needs rework. Most Olympia Chimney liner jobs we book in Bangor are completed in a single day, and we carry common diameters on the truck. Homeowners usually catch this problem during a routine sweep when our camera shows gaps, corrosion, or flaking terracotta - or when they notice a smoky smell in upstairs rooms after a fire.
Which Olympia Chimney Models This Applies To
Olympia Chimney manufactures stainless steel flexible liners in 316Ti and AL29-4C alloys, with the AL29-4C spec required for any condensing appliance or high-efficiency gas insert. In Bangor, we most often replace Olympia liners in 6-inch and 8-inch diameters, though we’ve handled everything from 5-inch pellet vent up to 10-inch for restored fireplaces in the older homes near the Bangor Borough Historic District.
Identifying your exact liner means checking the collar stamp near the top termination - Olympia stamps the alloy grade and UL listing number there. If the stamp’s corroded (common after 15+ Pennsylvania winters), we measure the inner diameter with a caliper and check the appliance BTU rating to spec the replacement. OEM Olympia liner runs about 15% more than quality aftermarket equivalents from DuraFlex or Gelco, but the gauge and corrugation pattern match exactly. For most Bangor homeowners, we recommend sticking with 316Ti minimum - the AL29-4C upgrade only pays off if you’re running a 90%+ efficiency appliance.
One compatibility gotcha we’ve seen twice in Bangor: Olympia’s early 2000s “Pro-Flex” series used a slightly different corrugation pitch that doesn’t mate cleanly with current Olympia connectors. We spot this during camera inspection and adapt with a custom transition - no surprises on the bill.
Signs Your Olympia Chimney Flue Liner Replacement Is Failing
- Smoke drafting back into the room. A separated or perforated liner breaks the sealed flue path, especially in Bangor’s older masonry chimneys where freeze-thaw cycles have already stressed the terracotta. The smoke has nowhere to go but out the fireplace opening.
- White or orange staining on exterior brick. This is acid condensation eating through a failed liner and leaching salts through the mortar joints. In Pennsylvania’s wet shoulder seasons, we see this accelerate once the liner’s compromised.
- Chunks of clay or metal flakes in the firebox. Terracotta flue tiles spall when a liner shifts or gaps open; stainless flakes mean the liner itself is corroding from the inside, usually from burning unseasoned wood or a boiler producing acidic condensate.
- Strong odor even when the fireplace isn’t in use. A liner with gaps lets downdrafts carry creosote smell into the house. Russell Haines notes this is the complaint that wakes people up at 2 a.m. - and the one that doesn’t fix itself.
- Water in the cleanout or rusted damper. A liner should shed water to the top; cracks let it run down the flue walls. Bangor’s spring rains find every opening.

What drives the spread: height of the chimney (two-story Bangor colonials run longer than ranch liners), diameter, and whether we’re pulling new through existing terracotta or rebuilding a chase that was never meant for a liner. Our estimate includes the Level-2 camera inspection, the photo report you can see, and disposal of the old liner. No-hassle upfront pricing means the number on the estimate is the number on the invoice. Everything’s covered by our 90-Day Done Right Promise - in writing, no arguing.
DIY or Call Us?
There’s no safe DIY path for flue liner replacement. This is roof work with a heavy, flexible metal tube that has to be tensioned correctly at the top and sealed at the bottom without collapsing the corrugation. A dropped liner tears shingles, dents gutters, or worse - a 30-foot stainless coil with momentum behind it. The combustion connection has to be gas-tight; a leak there vents carbon monoxide into the chase.
What you can do: check your cleanout for debris, look up the flue with a flashlight for visible gaps, and note any model numbers on your existing top termination. Then call us at (610) 609-7634. We’ll camera it, show you what we found, and give you a price that doesn’t change. Most liner replacements in Bangor we finish in one visit.
FAQs
A properly installed 316Ti liner typically lasts 15 to 25 years in Pennsylvania’s climate, though we’ve seen premature failure at 8 years when connected to an oversized or unlined boiler. Annual inspection catches corrosion before it breaches. Call (610) 609-7634 to schedule - estimates are free.
Small gaps at the top can sometimes be addressed with a HeatShield cerfractory seal, but only if the liner is otherwise sound and the damage is accessible. If the liner is perforated, separated, or corroded along its length, replacement is the only code-compliant fix. We document this with camera photos so you can see exactly what we’re seeing. Call (610) 609-7634 for an exact quote - estimates are free.
Most Olympia Chimney liner replacements in Bangor take 4 to 6 hours from ladder set to final smoke test. If the chase needs reframing or the thimble requires modification, we may need a second day - but we tell you that before we start, not after. Call (610) 609-7634 to book - estimates are free.
We carry 6-inch and 8-inch 316Ti liner in common lengths, plus DuraFlex and Gelco equivalents for same-day availability. Odd diameters or AL29-4C we pull from our Easton supplier, usually next-morning. A clean flue does not need a sales pitch - we’ll tell you honestly if we can finish today or if the right part needs a day to arrive. Call (610) 609-7634 to check current stock.
