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.

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

Our Chimney Liner & Rebuild Services in Hauppauge
Stainless Steel Liner Installation
Hauppauge’s oil-to-gas conversion wave has made stainless steel liners our most requested service in this market. The original clay-tile flues in 1960s and 1970s homes were sized for oil-fired boilers that ran hot and fast. Natural gas exhaust is cooler and wetter, and an oversized flue can’t generate enough draft to carry it safely out of the house. We install DuraFlex stainless steel liners sized precisely for your new gas appliance, creating a sealed, correctly dimensioned passageway that meets National Fuel Gas Code requirements. On a 1968 split-level off Veterans Memorial Highway, our tech found the original clay-tile flue liner spalling and heavily coated with both oil soot and third-degree creosote from decades of dual-use. We installed a DuraFlex stainless steel liner sized for the home’s new gas boiler and replaced the cracked chimney crown and cap. The homeowner noticed an immediate improvement in draft and no more odor in the living room.
Flexible Liner Installation
Not every Hauppauge chimney is straight. The offset flues in some split-levels and raised ranches need a liner that can navigate bends without losing integrity. We use flexible stainless steel liners from trusted manufacturers for these applications, installed with the same precision as rigid systems. Every flexible liner we install is rated for the specific appliance it serves and comes with proper insulation to prevent condensation in Hauppauge’s hard freeze-thaw cycles.
Liner Replacement
When a clay-tile liner has spalled, cracked, or separated at the joints, patching is rarely the right call. We remove the damaged liner and install a new system that restores the chimney’s safety and performance. In Hauppauge, we replace liners that have failed from thermal shock after oil-to-gas conversion, from decades of corrosive oil soot, or from freeze-thaw damage accelerated by water intrusion through cracked crowns. Our Chimney Liner & Rebuild team documents every stage with photos so you understand exactly what was wrong and what we fixed.
Partial Rebuild
Sometimes the liner isn’t the only problem. In Hauppauge’s mid-century chimneys, we regularly see crown deterioration, spalling brick, and eroded mortar joints caused by central Suffolk County’s harder freeze-thaw cycling compared to coastal Long Island. A partial rebuild addresses the damaged section - crown, upper courses of brick, or smoke chamber - while preserving sound lower structure. This is often the right approach for a 55-year-old chimney where the lower masonry is solid but the top has taken the worst of the weather.

Common Chimney Liner & Rebuild Problems We See in Hauppauge Homes
- Clay-tile liners cracked by oil-to-gas conversion. The thermal cycling of a new gas boiler is fundamentally different from the hot, dry exhaust of an oil furnace. Original liners in Hauppauge’s 1960s ranches crack under the new stress pattern, creating gaps where carbon monoxide can leak into living spaces.
- Dual-use flues with layered oil soot and creosote. Hauppauge’s post-war subdivisions were built with a single shared flue for both the oil boiler and the fireplace. Decades of intermixed oil soot and wood creosote create a hardened, glazed deposit that standard brushing won’t remove - and that can reignite if left in place.
- Prefabricated chase deterioration on newer infill homes. Even Hauppauge’s more recent construction can develop rusted chase caps and failed flashing. Water enters the system, degrades the factory-built firebox, and creates hidden damage that only a camera inspection reveals.
- Crown and mortar damage from hard freeze-thaw cycling. Hauppauge sits far enough inland to experience harder winter freezes than coastal communities. Water penetrates small crown cracks, expands when it freezes, and widens the damage until the crown fails completely and water runs down the flue walls.
Pricing for Chimney Liner & Rebuild in Hauppauge, NY
A typical stainless steel liner installation in Hauppauge runs $2,200-$3,800 for a standard single-flue residential chimney up to 25 feet. Flexible liner installations in offset flues range $2,600-$4,200. Liner replacement where we must first remove damaged clay tile starts around $2,800. Partial rebuilds involving crown replacement and upper masonry repair run $1,800-$4,500 depending on height and accessibility.
What moves the number: flue height, number of appliances being vented, whether the clay tile must be removed or can be left in place, and the condition of the crown and exterior masonry. We provide no-hassle upfront pricing before any work begins - the estimate we agree to is the invoice you pay.

FAQs - Chimney Liner & Rebuild in Hauppauge
Your original clay-tile flue was sized for the hot, fast exhaust of an oil-fired boiler, and it’s now coated with oil soot that changes how gas exhaust behaves. Natural gas produces cooler, wetter exhaust that an oversized flue cannot draft properly - the moisture condenses on the flue walls, the draft is weak or reversed, and carbon monoxide can spill into your home. A properly sized stainless steel liner creates the correct dimensions and a smooth surface for gas exhaust to rise and exit safely. Call (631) 814-2057 and we’ll measure your flue and show you exactly what conversion requires.
Every chimney in Hauppauge should receive a Level-2 inspection at least once per year, regardless of use frequency, because the heating appliance flue works all winter. Your boiler or furnace runs daily from October through April, and that flue - especially if it’s the original shared flue from the 1960s or 1970s - accumulates debris and suffers thermal stress whether you light fires or not. The few fires you do burn may add creosote to an already compromised system. Annual inspection catches liner damage before it becomes a carbon monoxide hazard.
Spalling clay tile shows up as flaking or crumbling pieces in the firebox, white efflorescence stains on the exterior brick, or bits of terracotta in the cleanout. You may notice a persistent smoky odor in the house, poor draft even on windy days, or visible cracks when you shine a light up the flue. In Hauppauge’s 1960s ranches, spalling accelerates after oil-to-gas conversion because the cooler exhaust keeps the flue surface wet longer, promoting freeze-thaw damage. Only a camera inspection can show the full extent - surface signs mean the damage is already advanced.
Yes, most prefabricated chase problems are repairable without full replacement. Rusted chase caps, failed flashing, and water-damaged surround panels are common on Hauppauge’s newer infill homes, and we can replace the cap, reflash the penetration, and repair the chase structure using manufacturer-compatible materials. The factory-built firebox and flue inside may also need attention if water has been entering for multiple seasons. We’ll inspect with a camera and tell you honestly whether repair or replacement is the right call - nothing is recommended without photo evidence you can see for yourself.
We treat dual-use flues as the specialized cleaning job they are. Standard rotary brushing alone won’t remove hardened third-degree creosote that’s intermixed with oil soot - the layers have different densities and bond differently to the flue surface. Our technicians use mechanical de-glazing tools and appropriate chemical treatments to break down the deposits, followed by thorough HEPA vacuuming. In Hauppauge, where this configuration is especially common in the 1965-1975 ranches off Veterans Memorial Highway and Townline Road, we’ve developed specific protocols that leave the flue clean enough for accurate camera inspection and safe liner installation. The work takes longer than a standard sweep, but it’s the only way to do it right.
