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.

AfterOlympia Chimney Flue Liner Replacement: The Stamford Owner’s Guide
An Olympia Chimney flue liner replacement in Stamford typically runs $2,850 to $6,400 installed, depending on the liner diameter, flue height, and whether the old liner comes out cleanly or fights us on the way up. We stock Olympia Chimney-compatible smooth-wall flexible liners in 4″, 5.5″, 6″, and 8″ diameters on most days, which means a straight swap on a standard Stamford chimney usually happens same-day. Most owners find out the hard way that the liner has failed: they get a chimney inspection before the burning season, or they notice rust flakes collecting in the firebox, or the damper starts sticking where it never stuck before.
Here’s the thing about Olympia’s smooth-wall liner design. It’s a good liner. But in Fairfield County weather, the weak point is almost always the seam where the liner meets the connector at the appliance outlet, or at the top plate where freeze-thaw cycles work the silicone loose. We see it every November in Stamford: the liner body is fine, but moisture has crept in at a termination point and started eating at the interior wall. The camera tells the story.
Which Olympia Chimney Models This Applies To
Olympia Chimney’s liner product line has stayed consistent over the years, which helps with matching. The smooth-wall flexible stainless liners and the hybrid liners (316Ti alloy exterior, smooth interior) are the two series we see most often in Stamford homes built or relined between 1995 and 2020. If your liner was installed as part of an Olympia Chimney reline kit, the diameter is usually stamped or printed on the liner’s top edge near the cap, or on the connector boot at the appliance end. If it’s not legible, we measure. Always.
The compatibility gotcha worth knowing: Olympia’s smooth-wall liners run true to spec on diameter, which sounds obvious until you realize some aftermarket liners run slightly undersized. If a previous contractor installed a liner that wasn’t actually Olympia and labeled it as such, the coupling at the appliance outlet may not seat correctly. That’s a finding we document with photos and include in the written scope before anyone touches a wrench. For OEM, we source directly through our supplier network. For equivalent aftermarket, we use materials from DuraFlex or HeatShield only when the application calls for it and we tell you why before ordering. Level Two Chimney Stamford is an independent service provider, not affiliated with Olympia Chimney, and we’ll say so on the invoice.
Signs Your Olympia Chimney Flue Liner Replacement Is Failing
- Rust flakes or scale in the firebox. Stainless liners don’t rust through easily, but the connector and hardware do. Flakes mean moisture is getting in somewhere above the firebox and carrying iron oxide down. That’s not normal and it’s not seasonal.
- Condensation or staining on the exterior masonry near the flue. When a liner develops a pinhole or a failed seam, warm flue gas meets cold masonry and the moisture condenses inside the chimney chase. You’ll see efflorescence or damp patches that weren’t there two winters ago.
- A smell that reads like a damp campfire after rain. Creosote trapped between the liner and the original flue tile has a distinct odor once it absorbs moisture. If the smell hangs around in summer when you’re not burning, the liner has a breach.
- Visible distortion or waviness in the liner from the top. If you can see the liner from the roof and it looks wavy or deformed, that’s thermal fatigue. It happens faster on chimneys that run hot and then cool fast, which describes most Connecticut winters.
- Draft problems that weren’t there before. A liner that has collapsed internally or separated at a seam can’t maintain proper draft. Your fire smokes, the room smells, and no amount of damper adjustment fixes it because the problem is inside the flue, not at the firebox.
BeforeAfterReplacement Cost & What’s Included
For Stamford homeowners, here’s the installed range we quote most often:
- 4″-5.5″ smooth-wall liner, straight vertical flue: $2,850-$3,800
- 6″ smooth-wall liner, one-story flue: $3,400-$4,600
- 6″-8″ liner, two-story flue or steep chase: $4,200-$5,800
- Anything requiring a new top plate, cap, or chase repair: add $350-$700 materials and labor
The range comes down to three variables: the liner diameter, the flue height, and whether the old liner is friction-fit against the clay tile or left slack. A friction-fit liner in a clay tile flue with a jog in the middle may take two hours just to extract. We price the job in writing before work starts, per Haven Standard Clause 1. No ‘call for a quote,’ no surprise add-ons. The written quote includes the liner, connector, top plate, cap, labor, and the camera re-scan and photo record on completion. Warranty on the liner runs through the manufacturer; our workmanship carries the 365-Day Done Right Promise.
DIY or Call Us?
You can check a few things yourself: look for rust flakes in the firebox, smell for that damp-campfire odor, and shine a light up the flue from below to see if the liner looks wavy or separated at the seams. Those observations help us know what to expect. What you shouldn’t do is pull a liner out yourself. The liner is under tension in the flue, the top plate is caulked to the crown, and if the liner separates inside the chase, retrieving the lower section usually means roof access and a pulling cone. We’ve taken over more than one DIY project in Stamford where a homeowner got the liner halfway up and then wedged it against a damaged tile. That turned a straightforward swap into a multi-hour extraction. On top of that, working on a roof in Fairfield County in November means frost on the shingles and a real fall risk. If you’re not set up for roof work with a harness and a spotter, don’t start. Corrine Halstead has walked enough Stamford roofs to know exactly where the footing fails first. Call us at (914) 537-8463 and we’ll bring the camera, the pricing, and the written scope before anything gets touched.
FAQs
In our experience, a properly installed Olympia smooth-wall liner in a Fairfield County chimney lasts 15 to 25 years. The liner body usually outlives the top plate and connector hardware, which fail first from freeze-thaw stress and moisture exposure. The camera tells us which part gave out. Call (914) 537-8463 and we’ll show you the footage before you pay for the fix.
Sometimes. If the failure is at the top plate or the appliance connector, we can replace those components without pulling the whole liner. If the liner body has separated, perforated, or distorted, a patch is a temporary fix that violates the reason you put a liner in to start with. We’ll show you exactly what the camera found and recommend the repair only when the liner itself is sound.
A straight swap on a standard Stamford chimney takes us one day from setup to cleanup, including the camera re-scan and photo record. Steep roofs, two-story chases, or a liner that’s seized in the flue can push it to a second morning. We’ll tell you the time estimate in writing before we start.
We stock Olympia-compatible smooth-wall flexible liners in 4″, 5.5″, 6″, and 8″ diameters, plus the connectors, top plates, and caps. Specialty heights or hybrid alloy liners we order through our supplier network, usually two to three business days out. We also work with DuraFlex, HeatShield, and Gelco components when the job calls for it.
You get the camera footage from before and after, a written scope of work, the itemized invoice, and the manufacturer’s liner warranty plus our written workmanship record under the 365-Day Done Right Promise. Haven Standard Clause 4 requires the photo record on every job. We don’t skip it and we don’t charge extra for it.
Once a year, minimum, before the burning season. Even with a modern smooth-wall liner, the connector and cap accumulate creosote fastest. Stamford’s damp October air accelerates creosote formation in the upper flue, so we recommend an October sweep and camera inspection as a routine. Call (914) 537-8463 and we’ll get you on the schedule.
If the liner is intact, a sweep is all you need. If the camera shows a breach, a sweep doesn’t fix it. We never recommend a liner replacement without camera evidence you can see. ‘The camera doesn’t guess. Neither do we.’ When the liner is sound, we’ll say so and sweep it. When it’s not, we’ll show you the photo and give you a written price before anyone starts.
