Olympia Chimney Flue Liner Replacement Nationwide

Olympia Chimney Flue Liner Replacement: The Huntington Owner’s Guide

We stock and install Olympia Chimney-compatible flue liner replacement in Huntington, with most jobs running between $2,800 and $4,500 installed depending on height, diameter, and whether the existing liner pulls out clean or needs to be cut out in sections. Our trucks carry the common Olympia Chimney diameters from 5.5″ to 8″ in both rigid and flexible configurations, and we can typically inspect, measure, and begin work within a few days of your call. Most Huntington homeowners discover their liner has failed during a routine sweep when our camera catches a crack, or when they notice bits of terracotta flaking into the firebox after a hard freeze.

Which Olympia Chimney Models This Applies To

Olympia Chimney produces stainless steel flue liners in several series, and matching the right one matters for both safety and warranty coverage. The Olympia 316Ti flexible liner, their workhorse for wood-burning applications, comes in .006″ and .010″ wall thicknesses, and we see the thinner spec installed in many Huntington split-levels from the 1970s where the original clay liner has finally given out. The Olympia rigid 316L system, more common in straight-shot chimneys or oil-to-gas conversions, uses male-to-female section joints that must be sealed with the factory gasket, not generic RTV.

To identify what you have, look for the stamped oval label on the top termination collar, or the laser-etched band every 36″ on flexible runs. If the label’s corroded off, we measure the inner diameter with a chimney ruler and check the wall thickness with a caliper. Hearthstone Chimney Co. is an independent service provider, not affiliated with Olympia Chimney, but we source factory-spec material and will show you the mill certification sheet before we drop a liner down your flue. For most Huntington homes, the aftermarket equivalent from DuraFlex or Gelco meets or exceeds the original spec at a lower parts cost, and we stock both so you can see the difference before deciding.

Signs Your Olympia Chimney Flue Liner Replacement Is Failing

• White or gray powder staining the exterior brick. This is efflorescence from moisture migrating through cracks in the liner, and in Huntington’s freeze-thaw cycles it accelerates quickly. We’ve pulled failed liners in Southdown and West Hills where the surrounding brick was spalling badly because the leak went unaddressed for two winters.
• Bits of clay or metal flake in the firebox after burning. With an original clay liner, this means the terracotta is delaminating; with a steel liner, it often indicates corrosion at the weld seams where acidic condensate pools. Either way, the barrier between fire and framing is compromised.
• Smoke or odor in upstairs rooms when the fireplace is in use. A cracked liner can leak combustion gases into wall cavities or the attic space. In older Huntington colonials with balloon framing, this is a genuine carbon monoxide risk that we treat as an urgent call.
• Water dripping into the firebox during rain, even with a cap. The liner’s top collar or storm collar has separated, or the liner itself has cracked above the roofline. Olympia’s flex liner uses a specific top plate geometry, and an ill-fitting replacement cap will funnel water straight down.
• The sweep’s camera shows gaps, separations, or “alligator skin” corrosion. We document this with photos you can see, and a plain-English verdict. If the liner is 316Ti and shows pinholing, it’s often a condensation chemistry issue, not just age, and we address that too or the replacement will fail the same way.

Replacement Cost & What’s Included

What drives the range: chimney height, whether we can pull the old liner in one piece or cut it out through the thimble, and whether the top plate and rain cap need replacement too. Our estimate includes the liner, insulation if needed, top and bottom terminations, a Level-2 camera inspection before and after, and the 90-Day Done Right Promise in writing. The number on the estimate is the number on the invoice. We don’t charge extra for photos or the plain-English report, and we don’t recommend work without camera evidence you can see for yourself.

DIY or Call Us?

An owner can safely check three things: whether the damper opens fully, whether debris is visible in the firebox, and whether water stains appear on the ceiling near the chimney breast. Beyond that, flue liner replacement involves working on a steep roof with heavy material, dropping a liner that can bind or kink in an offset flue, and sealing connections to factory specifications. A misaligned top plate or missing storm collar will leak water for years before it shows inside. And if you’re dealing with a gas appliance, the liner sizing must match the BTU input exactly, per NFPA 54, or you risk carbon monoxide spillage.

We complete most liner replacements in a single visit, with background-checked, uniformed technicians who’ve done this work in Huntington long enough to know which houses on West Neck Road have the tight flue offsets that require a specific pull technique. Call (631) 776-4075 and we’ll schedule a camera inspection, show you exactly what we’re seeing, and price the job before any work begins. A clean chimney isn’t a luxury - it’s just the job done right.
