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.

AfterTrusted Chimney Liner & Rebuild for Southampton Homeowners
A Chimney Liner & Rebuild - Southampton project typically costs between $1,800 for a straightforward stainless steel liner replacement and $12,000 or more for a full chimney rebuild involving multiple flues and masonry restoration. Most liner replacements and partial rebuilds are completed in a single day, with full rebuilds requiring two to four days depending on weather and the complexity of the existing structure. Hearthstone Chimney Co. has been serving Southampton and the East End since 1984, and we document every recommendation with camera footage you can see for yourself before any work begins.
We’ve rebuilt chimneys in North Sea cottages from the 1920s, relined flues in waterfront homes near Shinnecock Bay, and replaced crumbling terra cotta liners in summer estates throughout Bridgehampton and Water Mill. Southampton’s coastal climate is hard on masonry. Salt air accelerates spalling in brick and mortar. Freeze-thaw cycles in unlined or damaged flues cause the kind of hidden damage that doesn’t announce itself until you’ve got smoke backing up into the living room or worse. That’s why we start every job with a Level-2 camera inspection, show you the footage, and explain what we’re seeing in plain English. No jargon, no pressure. Call us at (516) 619-2915 when you’re ready to talk it through.
Our technicians are background-checked, uniformed, and carry the professional-grade materials we need to complete most jobs in a single visit. We answer the phone with a live person, 24 hours a day, 7 days a week. And every job we perform is backed by our 90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork to file, no argument.
What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner
A stainless steel liner is a continuous metal flue pipe installed inside your existing chimney structure to contain combustion byproducts and protect surrounding masonry from heat and corrosion. In Southampton, we regularly recommend stainless steel for oil and gas heating systems and wood-burning fireplaces where the original terra cotta liner has cracked or deteriorated beyond repair. We use DuraFlex and Olympia Chimney stainless steel products, sized precisely to your appliance’s BTU output and venting requirements, with proper insulation blankets to meet UL 1777 standards for zero-clearance installation.
Flexible Liner
Flexible liners are corrugated stainless steel tubes that navigate offset flues, chimney bends, and other structural irregularities that rigid pipe cannot accommodate. We’ve installed flexible liners in historic Southampton homes where the chimney was built around a central hearth with multiple angles, and in properties where previous modifications left the flue path anything but straight. Our DuraFlex flexible installations include proper top connectors, bottom adapters, and insulation where required by code, all documented with before-and-after camera runs you can watch on our monitor.
Liner Replacement
Liner replacement becomes necessary when your existing flue liner, whether terra cotta, clay, or metal, has suffered thermal shock, corrosion, or structural failure that compromises safe venting. In the North Sea and Noyack areas, we see accelerated liner deterioration in homes where salt-laden air has combined with condensation to eat away at metal components, or where decades of heating system upgrades have left an undersized liner struggling to handle increased output. We remove the failed liner completely, inspect the surrounding masonry with our camera system, and install a replacement sized and rated for your specific appliance, with no-hassle upfront pricing agreed before we start.
Partial Rebuild
A partial rebuild addresses localized masonry failure, typically the chimney crown, upper courses of brick, or the area immediately surrounding the flue opening, without dismantling the entire structure. We’ve performed partial rebuilds on Southampton homes where the crown cracked and allowed water to saturate the top three or four feet of masonry, causing spalling and freeze-thaw damage that threatened the flue itself. Our partial rebuilds match existing brick and mortar where possible, install proper crown flashing and sealant, and integrate seamlessly with your liner system so the repair is structurally sound and visually consistent.
Full Chimney Rebuild
A full chimney rebuild is required when structural integrity has been compromised throughout the stack, often from long-term water infiltration, foundation settling, or catastrophic liner failure that has damaged surrounding masonry. We’ve completed full rebuilds in Flanders and East Quogue where chimneys had tilted away from the structure, in Jamesport farmhouses where multiple flues had collapsed internally, and throughout the Hamptons where deferred maintenance finally caught up with century-old construction. Our full rebuilds include engineered footing assessment where indicated, code-compliant flue sizing, proper clearance to combustibles, and materials from Copperfield and Famco for caps, dampers, and finishing components.
Liner Repair
Liner repair addresses isolated damage, cracks, or joint separation without full replacement, using specialized refractory products and techniques appropriate to the liner material and extent of failure. For minor terra cotta cracking or small gaps between flue tiles, we may recommend HeatShield cerfractory resurfacing, a product we’ve applied successfully in dozens of Southampton-area fireplaces where the liner was structurally sound but no longer gas-tight. We only recommend repair over replacement when our camera inspection confirms the surrounding liner is in serviceable condition, and we show you exactly what we found so you can make an informed decision.

Brands We Service for Chimney Liner & Rebuild
We’ve worked with Gelco stainless steel liner systems for more than two decades, and we keep their full range of diameters and adapter fittings on our trucks. Gelco’s multi-flue and single-flue products handle the high-efficiency oil and gas appliances common in Southampton’s older homes, and we’ve developed particular expertise in their insulated liner kits for exterior chimneys that see the full brunt of East End weather.
HeatShield cerfractory technology allows us to restore clay flue liners that would otherwise require complete removal and replacement. We’ve completed HeatShield applications in Cutchogue and Mattituck homes where homeowners wanted to preserve original construction, and in North Sea properties where the flue geometry made liner extraction impractical. The product carries a 20-year warranty when applied by certified technicians, and we document every application with camera verification of complete coverage.
Whether your chimney was originally lined with Olympia Chimney, DuraFlex, Gelco, HeatShield, Famco, or Copperfield components, or you’re not sure what you have, we can identify it, source the correct materials, and complete the repair or replacement to manufacturer specifications. We don’t substitute builder-grade parts to pad margin. The brands we carry are the brands we trust in our own homes.
Signs You Need Chimney Liner & Rebuild Right Now
- White staining or efflorescence on exterior brick indicates moisture is moving through the masonry, dissolving salts, and depositing them on the surface. In Southampton’s coastal environment, this often means your liner has failed and combustion gases are condensing inside the flue, or the crown has cracked and rainwater is saturating the structure. Either way, the freeze-thaw cycle is actively destroying your chimney from the inside out.
- Flakes of terra cotta in the fireplace or cleanout are pieces of your liner that have detached due to thermal shock, age, or chimney fire damage. Once the liner surface is compromised, hot gases can reach combustible framing, and creosote can accumulate in gaps between the liner and masonry. We’ve found this condition in homes throughout Sag Harbor and Hampton Bays where the homeowner had no idea a fire had occurred.
- Smoke or odors entering the living space mean your flue is no longer containing and venting combustion byproducts as designed. This can result from liner cracks, improper sizing after an appliance upgrade, or blockages from collapsed liner sections. Carbon monoxide is odorless and invisible. If you’re smelling smoke, the same pathway may be allowing far more dangerous gases into your home.
- Visible cracks or gaps in the chimney crown allow water directly into the structure, where it accelerates deterioration of both masonry and metal components. In Water Mill and Bridgehampton, we’ve rebuilt crowns that had been cracked for years, with water damage extending three and four feet down the stack. Crown repair is straightforward when caught early. Left alone, it necessitates partial or full rebuild.
- Rust stains on the chimney face or damper assembly signal that moisture is combining with metal components, corroding them from the inside. This often means a failed or missing liner is allowing acidic condensation to attack the flue, or that the chimney cap has deteriorated and is no longer keeping precipitation out. We replace rusted dampers with Famco and Copperfield components rated for coastal exposure.

How Much Does Chimney Liner & Rebuild Cost in Southampton?
A typical stainless steel liner replacement in Southampton runs $1,800 to $3,500 for a single-flue system, depending on diameter, height, and whether insulation is required by code; see how much Chimney Liner & Rebuild costs for more detail. Flexible liner installations in chimneys with offsets or bends generally fall in the $2,200 to $4,000 range. Partial rebuilds involving the crown and upper masonry courses typically cost $2,500 to $6,000. Full chimney rebuilds start around $8,000 and can exceed $15,000 for multi-flue structures with complex flashing and roofing integration.
Several factors move these numbers. Height matters: a two-story chimney with a steep roof pitch requires more scaffolding and labor than a single-story ranch. Access affects timing and cost: tight setbacks in older Southampton neighborhoods or waterfront properties with limited equipment access add complexity. The condition of the existing flue and surrounding masonry determines whether we can perform a straightforward pull-and-replace or must reconstruct portions of the chimney structure. And the appliance being vented, whether a wood-burning fireplace, oil furnace, or high-efficiency gas boiler, dictates liner material and sizing requirements.
The most expensive mistake is paying for work you don’t need based on a verbal assessment without visual evidence. We show you exactly what our camera sees. If the damage is localized and repairable, we say so. If work can safely wait a season, we say that too. Our estimates are free, detailed, and fixed. Call (516) 619-2915 to schedule yours.
