We’ve worked on chimneys along Montauk Highway, on the estate roads near Flying Point Road, and throughout the older farmhouses tucked behind the village center. Our crews serve Water Mill directly from our New York City office, and we understand the specific problems this stretch of the South Fork creates for chimney systems: salt air off Peconic Bay, nor’easter rain driven hard off the Atlantic, and the inverted seasonal pattern that leaves fireplaces idle all summer while owners are in residence.

Why Hearthstone Chimney Co. Is Water Mill’s Preferred Chimney Liner & Rebuild Company

Water Mill homeowners tend to stay in their houses for decades, and they remember a contractor who did not deliver. We have served communities across Long Island for over 42 years - since 1984 - and we plan to be here in thirty more. That changes how we approach every job. We document every inspection with photos you can see and a plain-English verdict. We back every liner installation and rebuild with our 90-Day Done Right Promise in writing: if it is not right, we make it right, no paperwork and no arguing.

Our technicians are background-checked and uniformed, and they complete most jobs in a single visit. The price we quote is the price on the invoice - a square deal, no surprises on the bill. Calls are answered by a live person 24/7, not a voicemail queue. For Water Mill properties with multiple flues and complex hearth systems, that accessibility matters when you’re coordinating around a weekend arrival or a pre-season opening.

We know the local housing stock: the 18th-century shingle-style farmhouses with original multi-flue masonry, the 1990s-2010s estates with four or five fireplaces and modified flue runs, and the renovation-era additions that extended chimneys without always updating the liner sizing. That local knowledge prevents the mismatched-liner problems we see in homes where an original stack was extended but never properly re-inspected.

Our Chimney Liner & Rebuild Services in Water Mill

Stainless Steel Liner Installation

Stainless steel liners are our standard recommendation for most Water Mill homes with deteriorated clay flue tiles or modified flue runs. We use DuraFlex and Olympia Chimney products - professional-grade, not builder-grade substitutes - sized precisely to the appliance or fireplace being served. A typical stainless steel liner installation in Water Mill runs $2,800-$4,500 for a single-flue system. For estates with multiple fireplaces, we often install several liners in one coordinated project.

The salt-laden air off Peconic Bay corrodes metal caps and dampers quickly, but a properly installed stainless liner with a matching cap gives you a sealed system from top to bottom. We see this especially on homes near the bay shore, where nor’easter rain has been finding its way down cracked mortar for years before anyone notices.

Flexible Liner Systems

Flexible liners solve the problem of offset flues and extended chimney runs - common in Water Mill renovation projects where an older farmhouse was expanded upward or outward. The flexible design navigates bends that a rigid liner cannot, maintaining proper draft in a flue that was never straight to begin with. Flexible liner installation in Water Mill typically costs $3,200-$5,000 depending on length and access.

We often recommend flexible liners for properties where the original chimney was extended during a 1990s or 2000s renovation. The original clay tiles may still look intact from the top, but a Level 2 camera inspection frequently reveals cracks at the transition point where the old stack meets the new.

Liner Replacement

When an existing liner has failed - cracked, corroded, or improperly sized from a previous installation - we remove and replace it with a system matched to current NFPA 211 standards and Water Mill’s specific conditions. Liner replacement in Water Mill generally runs $3,500-$6,000. We include a full camera inspection of the remaining masonry, a new cap, and proper insulation where required.

Many Water Mill homes have liners that were installed during the Hamptons building boom and are now twenty to thirty years old. Those liners were often sized for wood-burning fireplaces that have since been converted to gas inserts, creating a mismatch that affects draft and safety.

Partial Chimney Rebuild

A partial rebuild addresses the upper portion of the chimney - the crown, cap, and several courses of brick - when the lower structure remains sound. In Water Mill, we see this need frequently on historic farmhouses where the crown has cracked from freeze-thaw cycles and salt-air exposure, letting water saturate the top courses. Partial rebuilds in Water Mill typically range from $4,500-$7,500.

We rebuild with matching brick where possible and always re-cast the crown with proper slope and overhang to shed water. On a recent job near Head of Pond Road, we rebuilt the top six courses of a 19th-century chimney and installed a new copper cap; the original crown had been poured flat and was holding water like a birdbath.

Full Chimney Rebuild

When the entire structure has deteriorated - spalling brick throughout, compromised lateral stability, or multiple flues with failed liners in a shared masonry mass - a full rebuild is the only safe option. Full chimney rebuilds in Water Mill range from $8,500-$18,000 depending on height, flue count, and finish details. We handle permitting, scaffolding, and all masonry work, and we install new stainless steel liners as part of the project.

On a 1990s estate off Montauk Highway near Flying Point Road, our tech found the original clay flue tiles had spalled and cracked after a winter of wind-driven nor’easter rain entering an uncapped flue; we pulled a length of DuraFlex stainless steel liner down the modified flue run, re-set the firebox and damper, and re-cast the chimney crown. The homeowners had been running a gas insert on the first-floor fireplace and never noticed the rear flue was partially blocked by an old starling nest until our Level 2 inspection caught it.

Trusted Brands We Service in Water Mill

We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - no substitutes. For Water Mill customers, this means we stock the liners, caps, and rebuild components that match your system, so we’re not ordering parts and leaving your chimney open for a week. A DuraFlex stainless liner paired with a Famco or Copperfield cap gives you a system built to handle the salt air and wind exposure that comes with a South Fork location. HeatShield cerfractory resurfacing lets us restore a sound clay flue in select cases without full liner replacement, saving some Water Mill homeowners a significant expense when the damage is surface-level.

Common Chimney Liner & Rebuild Problems We See in Water Mill Homes

• Salt-air corrosion of metal components. Positioned between the Atlantic Ocean and Peconic Bay, Water Mill chimneys face salt-laden air that erodes mortar joints and corrodes metal flashing, caps, and dampers significantly faster than even nearby inland Suffolk County towns. We replace these components with marine-grade materials as standard practice.
• Clay flue tile spalling in historic farmhouses. The 18th- and 19th-century shingle-style and colonial-era homes throughout Water Mill contain original clay flue tiles that crack and spall during the long idle summer-to-fall cycle. Once cracked, they cannot safely contain third-degree creosote or the byproducts of gas combustion.
• Summer bird nesting in uncapped flues. Water Mill’s inverted usage pattern - fireplaces idle May through October while owners are in residence - lets chimney swifts and starlings nest in uncapped flues all summer, so our autumn calls routinely find blocked flues on the exact first cold weekend a family lights a fire. Bird exclusion and nest removal have become a near-standard part of every autumn service call.
• Mismatched liners in renovation-era flue extensions. Older Water Mill homes with additions from the 1990s-2010s frequently have extended flue runs that were never properly inspected. A flexible liner sized for the original stack won’t fit the extended run and drafts poorly from day one, creating smoke backup and creosote buildup.
