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 Seaford Owner’s Guide
We stock and install Olympia Chimney-compatible flue liner replacement for Seaford homes, with most jobs running between $2,800 and $4,500 installed depending on height, diameter, and whether the chase needs refractory work. Our trucks carry the common Olympia Chimney stainless and aluminum alloy diameters, so we can often measure, match, and install without a second trip. Most Seaford owners discover their flue liner has failed during a pre-burning-season inspection, when our camera catches gaps, spalling, or corrosion that wasn’t visible from the firebox.
Which Olympia Chimney Models This Applies To
Olympia Chimney manufactures several liner series, and matching the right replacement means reading the collar stamp or measuring the existing run with a caliper, not eyeballing it. The Olympia 316Ti stainless flexible liner, their workhorse for wood-burning applications, comes in diameters from 3 to 12 inches and is not interchangeable with their 304-grade economy line on high-heat installs. The AL29-4C alloy series, rated for gas and oil condensing appliances, carries a distinct rib pattern and requires matching connectors; mixing collar types between series will leak.
We carry both OEM Olympia Chimney components and compatible aftermarket equivalents from DuraFlex and Gelco. For most Seaford installations, we recommend staying with Olympia’s 316Ti if the original served well, but we’ll spec DuraFlex when the chase configuration demands tighter bend radius or when the homeowner wants the added warranty coverage. We measure on-site, verify the appliance BTU output against the liner rating, and confirm compatibility before any material gets cut.
Signs Your Olympia Chimney Flue Liner Replacement Is Failing
- White or green powder on the liner walls. This is chloride-induced corrosion, common in Seaford’s salt-air environment, especially for homes within a mile of the harbor. The liner metal thins from the outside in, and once the surface crystallizes, the remaining wall life is measured in months, not years.
- Chunks of clay tile in the firebox or cleanout. If your chimney was originally clay-lined and an Olympia flexible liner was retrofitted, falling tile means the liner has shifted or compressed, creating gaps where combustion gases can reach the masonry. Carbon monoxide follows those paths.
- Wet stains on interior walls near the chimney chase. A breached liner allows acidic condensate to reach the brick or framing. In Seaford’s freeze-thaw cycles, that moisture expands and contracts, opening mortar joints and worsening the leak with every winter.
- Smoky smell when the fireplace is not in use. This usually indicates a liner separation at a joint or collar, allowing downdrafts to carry creosote odor into the living space. The liner is no longer a sealed conduit.
- Visible gaps or waviness on camera inspection. Our Level-2 inspection with a chimney camera reveals liner deformation, joint separation, or corrosion pitting that a flashlight from below cannot catch. We photograph everything and walk you through the footage.
Replacement Cost & What’s Included
| Scope | Typical Range in Seaford |
|---|---|
| Olympia 316Ti stainless liner, 25-35 ft run, standard diameter | $2,800 - $3,800 |
| Olympia AL29-4C alloy liner, gas/oil condensing application | $3,200 - $4,200 |
| Chase top replacement or refractory panel repair (if needed) | $400 - $900 additional |
| Insulation wrap for UL 1777 compliance (required on some installs) | $350 - $600 additional |
What drives the range: chimney height, number of offsets or bends, whether we need to remove an existing damaged liner first, and the condition of the top plate or chase cover. We price everything upfront after inspection, not after we’re halfway up the ladder. The number on the estimate is the number on the invoice. Our 90-Day Done Right Promise covers the installation in writing, no arguing. We also honor a permanent 5% Senior and Veteran discount, and we offer $50 off any repair over $250.
DIY or Call Us?
A homeowner can safely check the firebox and cleanout for debris, look up the flue with a flashlight for obvious gaps, and verify the appliance rating plate for BTU output and fuel type. Do not attempt to measure, cut, or install a flue liner yourself. The work involves working at height on a pitched roof, handling sharp stainless edges, and properly seating connectors that must withstand 1,200-degree temperature swings and corrosive condensate. An improperly seated liner collar or missed insulation gap can channel carbon monoxide into wall cavities or attic spaces. We have seen Seaford homeowners attempt this and create problems that cost double to fix. Call (516) 614-4632 for a free inspection and honest estimate. We’ll show you the camera footage, explain what we found, and let you decide.
FAQs
A properly installed 316Ti stainless liner typically lasts 15 to 25 years, but Seaford’s salt air and freeze-thaw cycles can shorten that by a third if the chase cover leaks or the liner was not insulated. Annual inspection catches corrosion before it becomes failure. Call (516) 614-4632 to schedule - estimates are free.
Localized damage sometimes allows a HeatShield cerfractory resurfacing or a stainless repair sleeve, but only if the remaining liner wall is thick enough and the damage is accessible. If corrosion is widespread or the liner has separated at multiple joints, replacement is the only sound option. We document the condition with photos and give you a plain-English verdict.
Most Olympia Chimney flue liner replacements in Seaford are completed in a single day, assuming standard height and no masonry rebuild. We arrive with the matched diameter on the truck, remove the old liner, install and connect the new run, and perform a smoke test before we leave. You’ll have photos of the new install and a written warranty.
We stock the common Olympia Chimney diameters and series on our service trucks, and our warehouse carries the full range of DuraFlex, Gelco, and Olympia Chimney components. Most Seaford jobs require no ordering delay. If your chase has an unusual configuration, we measure, order if needed, and return to install - no charge for the second trip.
