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.

AfterFast, Reliable Chimney Liner & Rebuild Across Flushing
Chimney liner installation and rebuild work in Flushing typically runs $1,800-$4,500 for most homes, with shared-stack row houses and multi-flue jobs toward the higher end. We complete most liner and rebuild projects in a single visit after our Level 2 camera inspection confirms exactly what your flue needs. If your Flushing home still has its original clay tile liner from the coal or oil era, relining is not optional - it’s the fix the sweep alone won’t accomplish.
We’ve been dispatching crews from our New York City office to Flushing for decades, and we know the difference between a Murray Hill semi-detached Tudor and an Auburndale attached brick row house before we pull up. The phone rings through to a live person at (516) 206-6672, any hour, any day. We’ll book your camera inspection, show you the photos, and give you a plain-English verdict with upfront pricing before any work begins.
Why Hearthstone Chimney Co. Is Flushing’s Preferred Chimney Liner & Rebuild Company
Flushing homeowners call us because we’ve handled the exact chimney their house has - the shared stack with the neighbor’s flue on the other side, the oversized coal-era flue converted to gas in the 1980s, the spalling crown that Flushing Bay humidity keeps wet through March. Our Chimney Liner & Rebuild team documents every inspection with photos you can see and a written verdict you can understand. No jargon, no scare tactics, no pushing work that can wait.
Our 90-Day Done Right Promise is backed in writing with no arguing - if it’s not right, we come back. Technicians are background-checked, uniformed, and trained to trace flues correctly in Flushing’s dense attached housing before any liner drops. Most jobs finish in one visit. The price we quote is the price on the invoice. And when you call (516) 206-6672, a live person answers - not a queue, not an app, not tomorrow.
Our Chimney Liner & Rebuild Services in Flushing
Stainless Steel Liner Installation
A stainless steel liner is the right fix for most Flushing homes that have converted from oil to gas. The original clay tile liner in your 1920s-1940s brick colonial was sized for a coal furnace or oil boiler running at much higher temperatures. Gas exhaust is cooler and wetter, and it condenses inside that oversized flue, producing acidic moisture that eats clay tile from the inside out. We install DuraFlex and Olympia Chimney stainless steel liners sized precisely to your appliance’s BTU load, which stops the condensation problem and brings your flue up to modern code. In Flushing’s attached row houses, this work demands exact flue identification at the firebox - we trace, we photograph, we confirm before we cut.
Flexible Liner Installation
Some Flushing chimneys have offsets, bends, or narrow passages that a rigid liner won’t navigate, especially in the older Tudor-style colonials near Bayside Cemetery or the tighter stacks in three-family conversions off Roosevelt Avenue. A flexible liner from DuraFlex follows the existing flue path without dismantling masonry, which matters when you’re working in a shared stack and disturbing the neighbor’s flue is not an option. We camera-verify the fit before we commit to flexible versus rigid, and we show you that footage.
Liner Replacement
Full liner replacement becomes necessary when the clay tile is cracked, spalled, or missing sections - common in Flushing chimneys that have survived fifty or more freeze-thaw cycles with Flushing Bay moisture seeping through the crown. We remove the damaged liner and install a new stainless steel system with proper insulation and top-sealing, which is required by NFPA 211 for gas appliances in unlined or damaged flues. Our crews carry the inventory to complete most Flushing replacements same-day once the inspection is done.
Partial Rebuild
Not every failing chimney needs to come down. A partial rebuild targets the damaged section - often the crown, the top courses of brick, or the flue shoulder - while preserving sound masonry below. In Flushing’s climate, crown cracking is the entry point: moisture gets in, freezes, expands, and opens mortar joints that let more moisture in. We rebuild with proper crown slope, drip edges, and waterproofing, using materials rated for NYC’s freeze-thaw cycle. For shared stacks, we coordinate access with neighboring properties when needed, and we document the dividing wall condition so both flues are protected.

Trusted Brands We Service in Flushing
We do not use builder-grade substitutes. Our Flushing crews stock and install professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney - brands that publish test data and stand behind their products. HeatShield’s cerfractory resurfacing system lets us restore a clay liner that has minor cracking but sound structure, which can save a Flushing homeowner a full replacement when the damage is caught early. We keep common liner diameters and crown repair materials on our trucks so we’re not waiting on parts while your chimney sits open. The right material for your appliance, installed correctly, documented with photos - that’s the standard.
Common Chimney Liner & Rebuild Problems We See in Flushing Homes
- Shared-stack flue misidentification. In Flushing’s attached row-house blocks, two homes routinely share a single exterior chimney stack divided internally into side-by-side flues. Our crew was called to an Auburndale row-house block off Main Street where the homeowner’s gas boiler was drafting poorly and the basement smelled of exhaust. Tracing the clay tile liner from the firebox, our tech found the flue had been misidentified at some point and the neighbor’s water heater was venting into the same shared stack, with second-degree creosote and spalling mortar bridged across the dividing wall. We air-sealed and capped the correct flue, installed a HeatShield-restored liner sized for the boiler’s actual BTU load, and re-crowned the stack so the shared masonry stopped pulling in Flushing Bay humidity.
- Oversized flues after fuel conversion. Queens carries one of the highest rates of oil-heated homes in all of NYC, and as Flushing properties convert to gas, the original flue is too large for the new appliance. Cool gas exhaust condenses on the clay tile, producing sulfuric acid that deteriorates the liner from the inside. A sweep brushes the surface but cannot fix the sizing problem - relining is the actual repair.
- Freeze-thaw crown and mortar damage. Flushing sits close to Flushing Bay and the tidal estuary system feeding into Long Island Sound, giving it consistently higher ambient humidity than inland parts of Queens. This extra moisture penetrates aging mortar joints and brick crowns, and the NYC freeze-thaw cycle - temperatures regularly cycling above and below 32°F throughout winter - accelerates crown cracking and spalling each season. Once the crown fails, water reaches the liner and the interior masonry.
- Skipped Level 2 inspections. A visual look from the roof or a basic sweep cannot reveal cracked tile in the shared dividing wall, offset flues, or hidden deterioration where Flushing’s humidity has already opened joints. We camera-inspect every liner job before quoting work, and we show you the footage. No photos, no verdict - that’s our rule.

FAQs - Chimney Liner & Rebuild in Flushing
Yes, we can reline your flue independently, but the work requires precise identification of your flue at the firebox and careful protection of the dividing wall between the two flues. We camera-trace from your appliance to the top of the stack, seal the work area to prevent debris entering your neighbor’s flue, and document the condition of the shared masonry before we begin. In Flushing’s attached housing, this is standard procedure for us, not an exception. Call (516) 206-6672 to schedule a trace-and-inspect - estimates are free.
The original clay tile liner was sized for oil combustion temperatures, not the cooler, wetter exhaust from a gas appliance. The oversized flue lets gas exhaust cool too quickly, condensing acidic moisture that deteriorates the clay from the inside. Sweeping removes surface buildup but cannot change the flue diameter. A properly sized stainless steel liner stops the condensation at its source. We see this exact pattern in Flushing’s converted 1920s-1940s stock regularly, and relining - not repeated sweeping - is the fix that lasts.
Flushing’s proximity to Flushing Bay and the Long Island Sound estuary system means consistently higher ambient moisture than inland Queens. That moisture penetrates the crown through hairline cracks, reaches the mortar joints, and accelerates deterioration through the freeze-thaw cycle. A compromised crown lets water reach the liner and interior brick, which is why our partial rebuilds always include proper crown slope, drip edges, and waterproofing rated for NYC’s winter conditions. We inspect crown condition as part of every liner evaluation.
A Level 1 inspection is a visual examination of readily accessible portions of the chimney - what a sweep can see during routine cleaning. A Level 2 inspection is required before any liner installation, replacement, or real estate transaction, and includes video camera scanning of the internal flue surface, attic and crawl space examination, and inspection of the exterior from roof or ladder. For Flushing’s shared stacks and older masonry, the Level 2 camera scan is non-negotiable - it reveals cracked tile, hidden offsets, and dividing wall conditions that a visual check cannot. We include the camera footage and a written report with every Level 2.
We can determine this during the Level 2 camera inspection. Second-degree or third-degree glazed creosote, especially in a shared stack where a neighbor’s appliance may be contributing, indicates a ventilation or sizing problem that sweeping alone will not fix. The camera shows us the creosote type, the liner condition beneath it, and any hidden damage. We will show you the footage, explain what caused the buildup, and recommend either a sweep with improved burning practices or a liner replacement if the root cause is flue sizing. No recommendation without evidence - that’s our standard. Call (516) 206-6672 to book your inspection.
Your chimney liner is not a place for guesswork, and in Flushing’s dense, shared-stack housing, the stakes are higher. We trace every flue, photograph every defect, and quote every job with the number you’ll see on the invoice. If you’re in Auburndale, Murray Hill, or anywhere off Main Street and your chimney needs honest evaluation, call Hearthstone Chimney Co. at (516) 206-6672. A live person will answer, schedule your Level 2 camera inspection, and we’ll show you exactly what your flue needs.
