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.

We’ve been working on Dix Hills chimneys for decades. The large colonials off Deer Park Avenue, the wooded lots around Candlewood Road, the ranches near the Northern State Parkway corridor - we know the housing stock here because we’ve been inside so many of them. These are not generic suburban homes. They were built as upscale properties from the 1960s through the 1980s, and their chimneys carry a specific history that matters for every repair decision we make.

Homeowners here tend to stay put. Twenty, thirty, forty years in the same house. They’ve seen contractors come and go. They remember the ones who pushed unnecessary work, and they remember the ones who told them honestly that something could wait. We aim to be the second kind. Our Chimney Liner & Rebuild team has earned that trust across the Town of Huntington, and specifically in Dix Hills, by documenting every finding with photos before recommending a single dollar of work.
Dispatch and scheduling are coordinated from our New York City office, but our crews serve Dix Hills locally. That means we’re not driving from out of state or subcontracting to whoever’s available. We’re here. We know that a nor’easter hitting Long Island hard can compromise chimney crowns on these wooded lots where falling branches add impact damage to freeze-thaw stress. We plan for that.

Our Chimney Liner & Rebuild Services in Dix Hills
Stainless Steel Liner Installation
Dix Hills’s oil-to-gas conversion legacy makes stainless steel liners our most common installation. Those 1960s-1980s colonials were built with oversized masonry flues sized for oil-fired heating systems. When the furnace switched to natural gas, the lower heat output couldn’t properly warm that large flue volume. Moisture condenses. Mortar deteriorates from the inside out. New York State fuel-gas code requires technicians to document any liner-sizing deficiency during cleaning or inspection - and we do, with camera footage you can see.
A properly sized stainless steel liner, typically DuraFlex or Olympia Chimney depending on the appliance and configuration, restores correct draft and protects the remaining masonry. Most installations in Dix Hills run $2,200-$4,500 for a single-appliance flue.
Flexible Liner Solutions
Not every flue is straight. In Dix Hills’s custom and semi-custom homes, offset flues are common - the chimney may jog around a beam or framing element. A rigid liner won’t make that turn. We use flexible liners from DuraFlex when the flue path demands it, pulled through in one continuous piece to eliminate joints that could leak or snag debris. The material cost runs higher, but for offset flues it’s the only correct approach. Typical range: $2,800-$5,200.
Liner Replacement
Existing clay tile liners crack. They shift. They fail at the joints. In Dix Hills, we see this accelerated by that moisture-trapping problem - the flue was too large for the appliance, condensation saturated the masonry, and freeze-thaw cycles did the rest. Liner replacement means removing what’s damaged and installing a new system rated for your specific appliance. We don’t guess at sizing. We measure, we photograph, we show you the code requirement. Replacement jobs in Dix Hills typically fall between $1,800 and $3,800 for straightforward single-flue work.
Partial Chimney Rebuild
Sometimes the liner failure is a symptom, not the disease. The exterior stack has spalled brick, a cracked crown, failed flashing from too many Long Island winters. A liner alone won’t fix that. Our partial rebuilds address the damaged section - crown replacement, brick repair or replacement, flashing restoration - while preserving sound structure below. We use this approach when the lower chimney is solid but the top has taken the weather hit. Partial rebuilds in Dix Hills generally start around $4,500 and can reach $8,500 depending on height, access, and material matching.

Trusted Brands We Service in Dix Hills
We don’t use builder-grade substitutes. For Dix Hills installations, we specify professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney - brands that stand behind their products the way we stand behind our work. We stock common liner diameters and configurations locally, which means faster turnaround between inspection and installation. When a HeatShield application is right for a smoke chamber or firebox repair, we apply it to manufacturer spec. When a Gelco cap or Olympia Chimney component fits the job, that’s what goes on. No corners.
Common Chimney Liner & Rebuild Problems We See in Dix Hills Homes
- Oversized post-oil-conversion furnace flues. The heating flue in your two-flue stack was built for oil. After conversion to gas, it’s too large - drafts poorly, holds moisture, and rots interior mortar while the homeowner never sees a thing until the camera goes up.
- Third-degree glazed creosote from low, smoldering burns. Dix Hills homeowners with high incomes and busy schedules often burn wood only occasionally, running low fires that produce tar glaze a standard brush cannot remove. This requires chemical treatment or rotary removal, not a quick sweep.
- Spalling single-wythe brick after freeze-thaw cycles. Long Island’s pronounced winter freeze-thaw attacks the single-wythe brick construction typical of this era. The brick face pops off. Water gets in. The cycle repeats.
- Two flues, one stack, wrong diagnosis. We’ve found competitors selling a liner for the fireplace flue when the real problem was the unlined furnace flue, or vice versa - all because no camera was used, no code-required sizing check was performed, and the homeowner had no photos to verify.

On a wooded half-acre lot off Deer Park Avenue, a Dix Hills homeowner booked us for a routine creosote sweep on a two-flue exterior stack - one chimney serving the living-room fireplace, the other the converted gas furnace. Our tech scoped both flues, and the camera showed the furnace side was a bare oversized clay tile with spalling mortar and no liner rated for the appliance, while the fireplace flue carried third-degree glazed creosote a brush couldn’t touch. We installed a properly sized DuraFlex stainless liner on the heating side and HeatShield on the firebox and smoke chamber, then walked the homeowner through the footage before anything was ordered. That’s how we work. Photos you can see, a plain-English verdict.

FAQs - Chimney Liner & Rebuild in Dix Hills
Not necessarily both, but the heating flue almost certainly needs review. New York State fuel-gas code requires that any flue serving a gas appliance be properly sized for that appliance’s output. The oil-to-gas conversion so common in Dix Hills left many heating flues oversized, which creates moisture problems and draft hazards. The fireplace flue may be fine as-is, or it may have its own issues - we determine that with a Level 2 camera inspection of each flue separately. Nothing is recommended without photos you can see. Call (631) 528-2501 to schedule.
Because of the specific conditions here. The two-flue stacks, the oil-to-gas conversion history, and the code requirement to document liner sizing all mean a visual-only cleaning is insufficient. A Level 2 inspection uses a camera to examine the full interior flue surface, the smoke chamber, and accessible portions of the firebox. In Dix Hills, we routinely find liner deficiencies and creosote conditions that a brush-only visit would miss entirely. The inspection gives you documented evidence and a plain-English verdict. Estimates are free.
A standard wire brush cannot remove third-degree glazed creosote. That tar-like glaze, common in homes where fires are burned low and slow, requires chemical treatment or rotary mechanical removal. We assess the severity with the camera first. If glaze is present, we explain the removal method and cost before proceeding. No surprises on the bill. Call (631) 528-2501 for an exact quote.
No. Spalling brick and a cracked crown are entry points for water. Once moisture gets inside the stack, freeze-thaw cycles widen the damage, compromise the liner system, and can lead to structural failure. In Dix Hills’s single-wythe brick construction, this progresses faster than in older multi-wythe chimneys. We photograph the damage, explain what’s structural versus what’s weathering, and tell you honestly if work can wait or needs attention now. The camera doesn’t lie, and neither do we.
Partial rebuild when the lower structure is sound. Full rebuild when the damage extends below the roofline or when multiple wythes are compromised. We make this determination with visual inspection and camera evidence, not sales pressure. Most Dix Hills chimneys from the 1960s-1980s can be preserved with targeted repair if caught before water damage spreads. We’ll show you exactly what we found and why we’re recommending what we’re recommending. Call (631) 528-2501 - estimates are free, and nothing is sold without proof.
