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 Smithtown Homeowners
A Smithtown Chimney Liner & Rebuild typically costs between $1,800 and $6,500 depending on scope, with most Level-2 camera inspections completed same day and liner installations finished in a single visit. Hearthstone Chimney Co. has served Smithtown and Suffolk County for over 42 years, and our background-checked, uniformed technicians document every chimney with photos you can see and a plain-English verdict before any work begins. Call (631) 814-2057 and a live person will answer, 24 hours a day, 7 days a week.
We’ve rebuilt chimneys from the Village of the Branch to Fort Salonga, and we’ve learned what Smithtown’s coastal freeze-thaw cycles do to masonry and liners alike. The salt air coming off Long Island Sound, combined with decades of creosote buildup in homes built during the 1960s and 1970s, creates a specific pattern of deterioration we recognize immediately. When a liner fails or brick spalls, the risk isn’t abstract. Carbon monoxide can leak into living spaces. Combustible framing can overheat. We’ve seen both, and we treat every chimney as if our own family slept in the house below it. That’s why we back every liner and rebuild job with our 90-Day Done Right Promise in writing, no arguing. If it’s not right, we come back.
What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner
A stainless steel liner is a rigid or semi-rigid metal flue installed inside your existing chimney structure to contain combustion gases and protect masonry from corrosive byproducts. In Smithtown, we typically recommend stainless steel for oil and gas heating systems and wood-burning fireplaces where the original clay liner has cracked or deteriorated beyond repair. Hearthstone Chimney Co. uses professional-grade stainless from Olympia Chimney and DuraFlex, sized precisely to your appliance’s BTU output and installed with proper insulation to meet NFPA 211 standards. Most stainless steel liner installations in Smithtown are completed in a single visit, with no-hassle upfront pricing agreed before we start.
Flexible Liner
A flexible liner is a corrugated stainless steel tube that navigates offsets and bends in chimneys where a rigid liner cannot pass, common in older Smithtown colonials and Cape Cods with chimney structures that shift between stories. You’ll need a flexible liner when your chimney has a significant offset, when the flue is partially blocked by construction debris, or when relining must be completed without dismantling exterior masonry. Our technicians at Hearthstone Chimney Co. measure every flue with video scanning equipment before selecting the correct diameter and length of DuraFlex or Olympia Chimney flexible product, ensuring the liner seats properly at the appliance connection and terminates with a code-compliant cap.
Liner Replacement
Liner replacement becomes necessary when your existing liner, whether clay, metal, or cast-in-place, has reached the end of its service life through corrosion, thermal shock, or physical damage. In Smithtown homes with original construction from the 1950s through 1980s, we regularly find clay tile liners that have shifted during foundation settlement or cracked from rapid temperature changes during power outages. Hearthstone Chimney Co. removes the failed liner when possible, or abandons it in place with proper venting modifications, then installs a new liner system with a lifetime warranty on materials and our 90-Day Done Right Promise on workmanship.
Partial Rebuild
A partial rebuild addresses specific sections of chimney deterioration, typically the crown, the top few courses of brick, or a single wall that has suffered spalling, freeze-thaw damage, or impact from falling limbs. Smithtown’s mature oak and maple canopies in neighborhoods like Nissequogue and Kings Park Chimney Liner & Rebuild areas see branches that crack crowns and dislodge flashing, while the north face of chimneys in St. James and Nesconset often shows accelerated mortar decay from prevailing winds. Hearthstone Chimney Co. rebuilds only what needs rebuilding, matching existing brick and mortar where possible, and we document the before condition with photos so you understand exactly why each course was replaced.
Full Chimney Rebuild
A full chimney rebuild is required when the structural integrity of the entire stack has been compromised by long-term water infiltration, foundation settlement, or catastrophic events like chimney fires or vehicle impacts. We’ve completed full rebuilds in Smithtown after lightning strikes in the Harbor Heights area and after decades of neglected maintenance in older homes near the Smithtown Bull. Hearthstone Chimney Co. dismantles the existing chimney to the roofline or below, salvaging usable brick when appropriate, then reconstructs with proper footings, flue sizing, and weatherproofing using professional-grade materials from Copperfield and Famco. Every full rebuild includes a new liner system, a poured concrete crown with proper overhang and drip edge, and a written 90-Day Done Right Promise.
Liner Repair
Liner repair addresses localized damage, gaps between clay tiles, or minor corrosion spots in metal liners before they require complete replacement. In Smithtown, we often perform liner repair as part of annual maintenance for homeowners in Lake Ronkonkoma and Ronkonkoma who caught the problem early through our Level-2 camera inspection. Hearthstone Chimney Co. uses HeatShield cerfractory sealant for resurfacing clay flue tiles and patching small voids, or custom-fabricated stainless steel sleeves for isolated metal liner breaches. We never recommend repair when replacement is the safer long-term solution, and we show you the camera footage so you can see the difference for yourself.

Brands We Service for Chimney Liner & Rebuild
We’ve installed and serviced hundreds of Olympia Chimney liner systems across Smithtown and Suffolk County, from their premium stainless steel rigid liners to their insulated flexible products for offset flues. Their engineering tolerances match what we expect from our own workmanship, and we stock common Olympia components so repairs don’t wait on shipping. We’ve also worked extensively with DuraFlex flexible liners, particularly in the tight chimney configurations common in Smithtown’s older homes near the Village of the Branch, where a liner must navigate around a breast or through a modified flue path.
Our rebuild and repair work relies on Famco chimney caps, dampers, and flashing systems, plus Copperfield masonry products and sealants that we’ve tested through Long Island’s harshest winters. Whether you have an Olympia Chimney, DuraFlex, Famco, or Copperfield component, or any other professional-grade make, we can service it, repair it, or replace it with the correct specification. We don’t substitute builder-grade materials to cut costs, and we’ll show you the brand markings on every component we install.
Signs You Need Chimney Liner & Rebuild Right Now
- White efflorescence or spalling brick on your chimney exterior. This means water is getting inside the masonry and pushing salts to the surface, or freezing within the brick and flaking the face away. In Smithtown’s climate, this accelerates every winter, and once spalling begins, the structural deterioration moves faster than most homeowners expect.
- Bits of clay tile in your fireplace or cleanout. Those fragments fell from your liner, and every missing piece is a gap where heat, sparks, or combustion gases can reach combustible framing. We’ve found clay shards in Smithtown homes where the liner had been failing silently for years.
- Smoke or odors entering your living space during fireplace use. This indicates a breach in the liner, a blocked flue, or negative pressure pulling exhaust backward. Carbon monoxide is odorless and can accompany smoke, so any change in draft behavior deserves immediate professional inspection.
- Rust stains on your chimney exterior or around the thimble. Rust means moisture is combining with metal components, whether a deteriorating metal liner, failing flashing, or a compromised chimney cap. The metal won’t stop corroding on its own, and the water causing it is simultaneously damaging your masonry.
- Your heating technician has flagged “chimney issues” during annual service. HVAC professionals in Smithtown regularly refer homeowners to us after spotting liner deterioration, improper sizing, or venting configuration problems they aren’t equipped to repair. Their observation is a warning, not a diagnosis, and a Level-2 camera inspection from Hearthstone Chimney Co. will give you the complete picture.
Our Chimney Liner & Rebuild Process - Step by Step
- 1
Schedule your inspection. Call (631) 814-2057 and a live person will answer, any hour of any day. We’ll find a time that works for your schedule, typically within a few days for non-emergency appointments in Smithtown, Commack, and Hauppauge. We’ll confirm our $89 Seasonal Tune-Up option or arrange a Level-2 inspection if you’ve been told you need liner or rebuild work.
- 2
Level-2 camera inspection and documentation. Our background-checked, uniformed technician arrives with a video scanning system, photographing the interior of your flue from top to bottom. We document every crack, gap, glaze, or obstruction with time-stamped images you can see on the spot. You’ll receive a plain-English verdict, not a technical manual, explaining what we found and what it means for your safety.
- 3
Written estimate with no-hassle upfront pricing. If liner or rebuild work is needed, we provide a detailed estimate with line-item pricing for materials and labor. The number on the estimate is the number on the invoice. No surprises, no “while we were in there” add-ons. We’ll also tell you plainly when work can safely wait, because not every finding requires immediate action.
- 4
Professional installation with quality materials. For liner work, we use Olympia Chimney, DuraFlex, or other professional-grade products matched to your application. For rebuilds, we source matching brick and use Copperfield masonry materials and Famco components. Most jobs are completed in a single visit, with proper drop cloths, ventilation, and cleanup. You won’t know we were there, except for the chimney that works correctly.
- 5
Final inspection, photo documentation, and written guarantee. We verify every installation with follow-up camera inspection where applicable, provide you with before-and-after photos, and leave you with our 90-Day Done Right Promise in writing. If anything isn’t right, we make it right. No paperwork to file, no arguments to have. That’s the Keystone Standard we’ve operated under since 1984.
How Much Does Chimney Liner & Rebuild Cost in Smithtown?
A typical stainless steel liner installation in Smithtown runs $2,200-$3,800 for a standard straight flue in a single-story home, while flexible liner installations with offsets or multiple appliances range from $2,800-$4,500. Liner replacement where we must remove or abandon an existing system adds $400-$800 for extraction and disposal. Partial rebuilds of crowns and upper courses in Smithtown neighborhoods like Kings Park and St. James generally cost $1,800-$3,200, while full chimney rebuilds from the roofline up range from $4,500-$6,500 depending on height, brick matching requirements, and liner specification. Learn how much Chimney Liner & Rebuild costs for your specific situation.
Several factors move these numbers. The height and accessibility of your chimney affect scaffolding and labor time. Matching existing brick for aesthetic continuity in historic Smithtown areas like Nissequogue or the Village of the Branch may require sourcing from specialized suppliers. The number of appliances venting into the flue determines liner diameter and whether multiple connections are needed. Hidden damage discovered during demolition, such as rotted framing or compromised flashing, must be addressed for code compliance and safety.
To avoid overpaying, get a second opinion on any written estimate over $2,500. Hearthstone Chimney Co. provides free second opinions because we’ve seen Smithtown homeowners quoted for full rebuilds when a liner replacement would suffice, or sold “lifetime” liners with no warranty documentation. Our estimates include every line item, and we explain which work is urgent, which can be scheduled, and which might be deferred with monitoring. Nothing is recommended without camera evidence you can see for yourself.
Every free estimate includes the Level-2 inspection, photo documentation, and written findings. If you proceed with work, the inspection fee is credited toward your project. Call (631) 814-2057 to schedule, and remember our standing offers: $50 off any repair over $250, and a permanent 5% senior and veteran discount.
