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.

AfterFast, Reliable Chimney Liner & Rebuild Across Woodbury
Chimney liner installation and partial rebuilds in Woodbury typically run $1,800-$4,500 depending on flue count and accessibility, with most jobs completed in a single visit after a Level 2 camera inspection. If you live in one of Woodbury’s center-hall colonials or custom builds from the 1960s through the 1990s, there’s a good chance your chimney has two clay-tile flues in a shared chase - one for the fireplace, one originally for oil heat - and the second flue is often cracked, abandoned, and out of code. That’s where our Chimney Liner & Rebuild team starts: with a camera, a monitor you can watch, and a plain-English verdict on what actually needs doing.
We’ve been dispatching crews to Woodbury from our New York City office for decades. We know the area around Woodbury Road, the cul-de-sacs off Jericho Turnpike, and the larger lots south of the Long Island Expressway where the 1970s and 1980s builds sit. Our technicians are background-checked, uniformed, and carry DuraFlex and HeatShield materials on the truck so we’re not ordering parts after we arrive.

Why Hearthstone Chimney Co. Is Woodbury’s Preferred Chimney Liner & Rebuild Company
We’ve worked on chimneys in Woodbury long enough to recognize the patterns. The center-hall colonial with a two-flue chase built for oil and wood. The custom 1980s home where the original clay liner has been cooked by decades of slow, smoldering fires. The Tudor near the Cold Spring Harbor border where salt air off the Sound has eaten the mortar above the roofline while the brick below looks fine. This is not generic suburbia - it’s a specific housing stock with specific failure modes, and we document every one with photos you can see and a written report you can keep.
Our scheduling is coordinated from our New York City office, but our crews serve Woodbury locally and carry the inventory to complete most liner replacements and partial rebuilds in a single visit. We’ve built our reputation on the 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back. No paperwork battle, no callback queue. That’s the K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it.
Our upfront pricing means the number on the estimate is the number on the invoice. We’ve been answering the phone with a live person for over 42 years, and we plan to be here in thirty more. A company with that horizon does not burn a customer for a single job.
Our Chimney Liner & Rebuild Services in Woodbury
Stainless Steel Liner Installation
A stainless steel liner is the standard repair for a clay-tile flue that’s cracked, glazed, or out of code. In Woodbury’s larger colonials, we typically install DuraFlex 316Ti stainless liners - flexible enough to navigate offset flues in chimneys built during the 1970s construction boom, yet rated for wood, gas, and oil. We measure on site, cut to length, and insulate per NFPA 211. Most Woodbury installations run $2,200-$3,800 for a single-flue fireplace, including the cap, connector, and pull. If your chase has that second abandoned oil flue, we’ll assess whether it needs capping, sealing, or a separate liner for a new appliance.
Flexible Liner Solutions
Not every Woodbury chimney is straight. The custom builds off Jericho Turnpike and the split-levels near the Syosset border often have offsets or tight smoke chambers where a rigid liner won’t pass. We carry flexible DuraFlex in multiple diameters and can navigate bends that would stop a standard kit. Flexible liners are particularly useful when we’re lining a flue that was never designed for the appliance now venting into it - a common situation in Woodbury homes where a gas insert was dropped into a fireplace originally built for open wood burning.
Liner Replacement
Sometimes the liner is there but it’s failed. HeatShield cerfractory flue sealant can repair minor cracks and gaps in otherwise sound clay tile, but when the liner is shattered, shifted, or coated with third-degree creosote that brushing cannot remove, replacement is the only safe option. In Woodbury, we see this most often in fireplaces that see light use - the smoldering fires that homeowners assume are gentle on the system are actually the worst for glazed creosote buildup. A liner replacement in Woodbury typically runs $1,800-$3,200 for a standard fireplace flue, with multi-flue chases toward the higher end.
Partial Rebuild
When the upper chase is spalled, the crown is cracked, or the mortar joints have opened to the point that water is entering the flue system, a liner alone won’t solve the problem. We do partial rebuilds of the upper chimney - from the roofline up - replacing damaged brick, repointing mortar with matching mix, and pouring a new concrete crown with proper overhang and drip edge. In Woodbury, salt-laden air off the Long Island Sound corridor accelerates this damage on south- and east-facing exposures. A partial rebuild in Woodbury typically runs $3,500-$6,500 depending on chase height and brick matching.

Common Chimney Liner & Rebuild Problems We See in Woodbury Homes
- The abandoned oil flue in a shared chase. In Woodbury’s center-hall colonials, the second clay-tile flue was almost always the original oil-burner vent. After the gas conversion, it was left abandoned, often cracked open to the wall cavity. It’s a Town of Oyster Bay code violation that surfaces during a title search and blocks a sale - not a chimney problem until it is.
- Salt-air spalling above the roofline. Woodbury’s exposure to the Long Island Sound corridor means salt-laden air eats mortar joints and spalls brick on the upper chase. The damage sits where owners never look, hidden until a cap-level inspection finds a crown and flashing that stopped shedding water years ago.
- Third-degree creosote from smoldering fires. Woodbury’s upscale colonials often have fireplaces used only a handful of times per season. Infrequent, low-temperature burns lay down glazed stage-2 and stage-3 creosote that a brush cannot remove. The flue looks lightly used but is often the most dangerous.
- Freeze-thaw cracking in moisture-saturated masonry. Cold winters in Nassau County bring enough freeze-thaw cycling to crack crowns, open mortar joints, and split flue tiles - especially in chimneys with failed caps that let water saturate the brickwork year over year.

FAQs - Chimney Liner & Rebuild in Woodbury
A yearly sweep removes soot and stage-1 creosote, but it cannot assess the condition of the flue liner inside the chase. In Woodbury’s 1960s-1990s colonials, the original clay tile is often cracked, shifted, or coated with glazed creosote that brushing won’t touch - and there’s frequently that second abandoned oil flue open to the wall cavity. A Level 2 inspection uses a camera to document every inch of the flue surface, the smoke chamber, and the accessible portions of the chase. We end with photos you can see and a plain-English verdict on whether the flue is safe to use, needs repair, or requires a liner. Call (631) 776-4075 to schedule - estimates are free.
Light use is often the problem. In Woodbury’s upscale homes, fireplaces see only occasional evening fires, burned low and slow. Those smoldering temperatures produce stage-2 and stage-3 glazed creosote - a hard, tar-like deposit that adheres to clay tile and resists standard sweeping. The flue looks clean from below but is coated with a combustible glaze that a brush cannot remove. A liner replacement or HeatShield treatment is the only safe solution. We show you the camera footage before recommending anything. Call (631) 776-4075 for an inspection.
It’s almost certainly the original vent for your oil-fired boiler or furnace, abandoned after a gas conversion. In Woodbury’s center-hall colonials, this second clay-tile flue was standard construction from the 1960s through the 1990s. Left uncapped and unlined, it cracks over time and can open into the wall cavity or the adjacent flue - a fire hazard and a Town of Oyster Bay code violation. Homeowners usually discover it when a buyer’s inspector flags it before closing. We can cap and seal an abandoned flue, or line it if you’re installing a new appliance that needs a dedicated vent. The camera shows the condition before we quote any work.
Salt-laden air off the Long Island Sound corridor accelerates mortar joint erosion and brick spalling on the upper chase - the portion above your roofline that takes the full brunt of weather. In Woodbury, south- and east-facing chimneys show this damage first. The brick below the roofline is protected; the cap, crown, and top courses are not. A cap-level inspection reveals what you cannot see from the ground. We often find crowns that stopped shedding water years ago, saturating the masonry below for freeze-thaw damage every winter. A partial rebuild of the upper chase, with a properly formed crown and new cap, stops the cycle.
This is the right question to ask. The chimney industry has a reputation for recommending liners to every homeowner who calls. We do not. Every recommendation we make is backed by camera evidence you can see on the monitor while we inspect, and by photos in a written report you can keep or share with another sweep for a second opinion - which we encourage. In fact, we offer a Free Second Opinion on any written estimate from another company. If your clay tile is sound, we’ll tell you so and sweep it. If it’s cracked, glazed, or out of code, we’ll show you exactly where and explain why a liner is the safe repair. No pressure, no urgency language, just the facts documented like an engineer and explained like a craftsman. Call (631) 776-4075 and we’ll walk you through it.
