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 Chimney Liner & Rebuild in Commack: What to Know First
Chimney liner and rebuild work on Olympia Chimney systems in Commack typically runs between $1,800 and $6,500 depending on liner condition, flue height, and whether the masonry crown needs rebuilding alongside it. We’re an independent Olympia Chimney service provider, which means we install and repair their liners but we don’t answer to a manufacturer’s sales targets. Most liner jobs in Commack take one full day from setup to cleanup, and we give you an exact price before a single tool comes off the truck. If you own an Olympia Chimney system and you’ve been told it needs work, call (631) 502-3612. Wendell will tell you straight whether it actually does. This page is for Commack homeowners with Olympia Chimney fireplaces, stoves, or furnace flues who want an honest read on liner repair versus replacement.
Key Takeaways:
- Olympia Chimney liners fail in specific, predictable ways that a camera inspection will confirm or rule out in about twenty minutes.
- We quote one price before work starts. The number you hear is the number on the invoice.
- Every Olympia Chimney liner or rebuild job is covered by our 90-Day Done Right Promise in writing.
- Most Commack liner replacements are completed same day, with a live person answering your call around the clock.
How Olympia Chimney Products Fail - and How We Fix Them
Olympia Chimney builds solid stainless steel liner systems, but no liner lasts forever. Here’s what we actually see inside Commack flues, and what we do about it.
- Olympia Ventis series - seam separation at the twist-lock joints. The Ventis double-wall rigid liner uses a twist-lock connection at each joint. After years of heating and cooling cycles, those connections can work loose. The symptom is a faint metallic rattle when the wind hits the chimney, or a thin wisp of smoke at the joint line. We remove the affected section, inspect the inner wall for hot spots, and re-seat or replace the section with a factory matching piece. On older Ventis runs, we often recommend replacing the full liner rather than chasing individual joints, because once one joint walks, the rest are usually not far behind.
- Olympia flexible liner - kinking at the smoke-shelf transition. Olympia’s flexible stainless liners handle bends well, but the transition from the vertical flue into the appliance collar is where we see the most damage in Commack homes. If the liner was pulled through without a proper transition plate, it kinks right above the stove or insert. That kink becomes a creosote trap. The symptom is smoke spilling when you open the door on a cold start. Our fix is a proper appliance connector with the right transition plate, pulling the liner so it makes a smooth, continuous run without sharp angles.
- Galvanized outer wall corrosion on Olympia air-insulated chimney. Olympia’s air-insulated chimney systems, the ones with a galvanized outer casing, are common in 1990s Commack builds and do not love Long Island humidity. Hairline rust streaks down the siding near the chimney chase are the telltale sign. The outer wall can look rough while the inner stainless liner is still sound. We inspect with a camera first. If only the outer casing is rusted, that’s a partial exterior rebuild. If the inner liner has thinned, that’s a liner replacement. Both are jobs we do in Commack weekly during the shoulder months.
- Caught-on-install liner tears - Olympia’s thin-wall liner at the flue offset. Some Olympia flexible liners use a lighter-gauge stainless for the ribbed sections. At a flue offset, where the masonry chimney bends slightly to avoid a joist, the ribbed wall can catch on rough mortar and tear during installation. You will not see it from the top. A camera will show a small, jagged split, and the real problem is it lets flue gas into the masonry chase. We replace the stretched or torn section, often with a heavier-gauge DuraFlex liner when the offset is sharp, and we always film the full run after installation so you can see every inch yourself.
- Olympia crown-and-liner mismatch - mortar crown cracking at the liner collar. This one is less about the liner and more about what sits around it. In Commack, freeze-thaw cycles crack mortar crowns at the point where the Olympia liner passes through, and water follows the liner down into the firebox. The symptom is damp firebrick after heavy rain and a white mineral stain on the liner visible from the fireplace. We rebuild the crown with a poured crown and proper expansion joint, and we collar and seal the liner at the penetration. The liner usually survives. The crown does not.
Our Olympia Chimney Chimney Liner & Rebuild Process
Every job follows the same unhurried sequence. Here is what to expect when you call us about Olympia Chimney liner work in Commack.
- 1
The call. A live person answers at (631) 502-3612, often Wendell himself. We ask what you’re seeing: smoke, smell, water, rust, or a recent inspector’s report. You get an arrival window and an honest idea of what we might be looking at.
- 2
The look. We arrive, run a camera down the full flue, and check the liner, the crown, and the appliance connection. You watch the footage with us. No verdict comes from a flashlight poke from the roof.
- 3
The verdict. Wendell calls it like he sees it. If the liner has life in it, we say so and show you why. If it needs replacing, we name a fixed price for the full job before anything is ordered.
- 4
Parts decision. We use OEM Olympia connector sections where the system calls for them and we’ll say when a quality aftermarket liner from DuraFlex or a HeatShield repair is the better play. You know which and why before we order.
- 5
The work. The liner goes in, or the rebuild comes together, same day in most Commack jobs. We protect the hearth, run drop cloths, and clean up the work area like we found it.
- 6
The proof and the promise. We film the final installation, walk you through it, and hand you our 90-Day Done Right Promise in writing. If it is not right, one call brings us back at no additional cost.
What Olympia Chimney Chimney Liner & Rebuild Costs in Commack
Straight numbers, because that’s how we quote. A simple Olympia Ventis liner replacement in a one-story Commack ranch runs roughly $1,800 to $2,400. A flexible Olympia liner pulled through a two-story masonry flue with a new transition plate lands between $2,200 and $3,500. A partial rebuild with crown work and top-section repair adds another $800 to $1,500 on top of the liner. A full chimney rebuild from the roofline up, including new liner, flashing, and crown, starts around $4,800 and can reach $6,500 depending on height and brick condition. What moves the price: roof pitch, flue height, liner diameter, whether the old liner needs cutting out, and whether the masonry around it is sound. The estimate is free, and we never pad the number for the season.

FAQs
Yes, Olympia Chimney is still in business, and their liner components, connectors, and engineered chimney sections are available through trade suppliers we order from regularly in Suffolk County. As an independent Olympia Chimney service provider, we stock common Ventis connectors and flex liner adapters in our truck and can order anything else within a few days. Some older Olympia series, particularly the early galvanized air-insulated models, have been discontinued, and in those cases we match the inner diameter and connection style with a quality aftermarket equivalent so the system works without a parts scavenger hunt.
An Olympia stainless steel liner in a properly maintained Commack chimney typically lasts 15 to 25 years, with the shorter end for wood-burning flues that see heavy use and irregular sweeping. The variables are moisture exposure, creosote buildup, and the original installation quality. We have pulled Olympia liners out of 30-year-old chimneys that looked almost new, and we have replaced ten-year-old liners that were installed badly from day one. That is why the camera inspection matters more than the brand name. Call (631) 502-3612 and we’ll tell you exactly what you have.
A liner can sometimes be repaired, but it depends on what the camera shows. Small tears at the connector, loose twist-lock joints, and minor top-collar gaps are repairable. A liner with separations at multiple joints, heavy pitting through the stainless wall, or kinks that have hardened into creosote traps is a replacement job. We use HeatShield’s ceramic resurfacing system for some flues with cracked clay tile, and a pulled-in stainless liner for others. We will show you the footage and tell you plainly which path makes sense, including when the honest answer is to leave it alone.
For a failed liner or visible chimney damage, we typically get a crew out to Commack within two to five business days, and we prioritize urgent issues like water pouring into the firebox or smoke backing into the house. The actual liner replacement or rebuild is almost always completed same day once we’re on site, unless we are cutting out a full masonry stack, which can run into a second day. We give you a real arrival window and we call if it slips.
It can, in the right direction. If your Commack home insurer flagged the chimney after an inspection, a documented liner replacement with before-and-after camera footage gives you exactly what the underwriter wants to see. We provide the photos and a written description of the work for your records. The liner itself does not change your policy automatically, but proof that the flue was properly relined and the crown sealed usually removes the chimney condition from a renewal request.
