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 Forest Hills
Chimney liner installation and chimney rebuilds in Forest Hills, NY typically range from $1,800 for a straightforward stainless steel liner replacement to $8,500 or more for a partial or full rebuild of a century-old multi-pot stack. Most Forest Hills homes built between 1910 and the 1940s have original clay-tile flues or unlined secondary flues that were never designed for modern gas appliances, and our crews complete most liner replacements in a single visit. Call (516) 531-6315 - a live person answers 24 hours a day, and estimates are free.
We’ve worked on chimneys along Greenway North, in the Tudor Revival blocks of Forest Hills Gardens, and in the pre-war co-ops facing Queens Boulevard. The housing stock here is old enough to have real problems and distinctive enough that out-of-neighborhood crews routinely misdiagnose them. We don’t guess. Every recommendation starts with a Level 2 camera inspection, photos you can see, and a plain-English verdict.
Why Hearthstone Chimney Co. Is Forest Hills’s Preferred Chimney Liner & Rebuild Company
We’ve served Queens communities for over 42 years, and Forest Hills has been part of our route since the beginning. Our technicians know the difference between a 1920s Forest Hills Gardens multi-pot stack and a 1950s co-op shared flue system - and we know that confusing the two leads to bad estimates and worse work.
Our Level 2 camera inspections end with dated photos and a written verdict. If we recommend a liner replacement or a partial rebuild, you’ll see the cracked tile, the spalling mortar, or the third-degree creosote that justifies it. No camera evidence, no upsell. That’s the Keystone Standard we’ve operated under since 1984.
Dispatch and scheduling are coordinated from our New York City office, but our crews live and work in Queens. We don’t subcontract to out-of-state labor. Our technicians are background-checked, uniformed, and carry the professional-grade materials to complete most jobs in a single visit.
Every job is backed by our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back. A company that plans to be in town in thirty more years acts accordingly.
Our Chimney Liner & Rebuild Services in Forest Hills
Stainless Steel Liner Installation
A stainless steel liner is the right choice for most Forest Hills homeowners with a damaged or missing clay-tile liner. We install DuraFlex and Olympia Chimney stainless steel liners sized precisely to your appliance - boiler, water heater, or fireplace - and we anchor them with proper top plates and insulation where code requires. In Forest Hills Gardens, where multi-pot stacks serve multiple flues, we never isolate one flue without calculating how the change affects draft across the entire stack. We’ve seen crews cap two pots and leave the third open, creating negative pressure that pulls combustion gases into the house. We measure before we cut.
Flexible Liner Installation
Flexible liners solve offset flues and tight smoke chambers that rigid pipe can’t navigate. Many Forest Hills homes have shifted slightly over a century, and the flue path isn’t plumb. Our flexible DuraFlex liners conform to these offsets without crushing or kinking, and they’re rated for wood, gas, and oil appliances. For the pre-war co-ops along Queens Boulevard with shared masonry systems, flexible liners sometimes allow individual unit venting without disturbing neighboring flues - a coordination challenge we’ve handled many times.
Liner Replacement
When clay tiles are spalling, cracked, or missing, patching individual sections is usually a waste of money. The century-old lime mortar behind those tiles has already been penetrated by decades of freeze-thaw cycles. We replace the full liner with a stainless steel or HeatShield cerfractory system, and we address the mortar joints that caused the failure. In Forest Hills, where Queens’ humid continental winters deliver repeated freeze-thaw damage, a liner replacement without joint repair means you’ll be calling someone again in three to five years. We don’t do temporary fixes.
Partial Chimney Rebuild
When the crown is cracked, the mortar joints are eroded, and the flue liner is compromised, a partial rebuild restores the stack from the roofline up. We rebuild with matching brick where possible, pour a new concrete crown with proper overhang and drip edge, and install a cap system that sheds water instead of trapping it. For Forest Hills Gardens’ decorative multi-pot stacks, we preserve the architectural character - the terracotta pots, the corbelled shoulders - while bringing the venting system up to modern safety standards. The house still looks like itself. It just works.

Trusted Brands We Service in Forest Hills
We stock DuraFlex flexible and rigid stainless steel liners, HeatShield cerfractory resurfacing systems, and Gelco stainless steel caps and flashing - professional-grade materials, no builder-grade substitutes. For Forest Hills customers, this means faster turnaround. We don’t order parts from a catalog and make you wait two weeks. Our trucks carry the common diameters and fittings for the boiler and fireplace configurations we see in local homes, and we source Copperfield custom caps for the multi-flue stacks that require exact sizing. The brands matter because the warranty matters, and because a liner that fails in five years costs more than one that lasts twenty.
Common Chimney Liner & Rebuild Problems We See in Forest Hills Homes
- Unlined secondary flues after fuel conversions. When Forest Hills Gardens homes converted from coal to oil to gas, the secondary flues - fireplace, incinerator stub - were often abandoned uncapped and unlined. Moisture enters, wildlife nests, and the draft balance across the multi-pot stack is ruined. We find this on Greenway North and in the blocks near Station Square routinely.
- Freeze-thaw spalling in century-old mortar joints. Queens’ winters drive moisture into the lime-based mortar of 1910s-1940s chimney stacks. The mortar crumbles, the bricks loosen, and the liner loses structural support. Spring and fall nor’easters then drive rain through cracked crowns, accelerating the damage. Post-winter inspections catch this before it becomes a rebuild.
- Third-degree creosote in unlined fireplace flues. Glazed, tar-like creosote builds up in flues that were never lined or where the liner has failed. It’s not visible from the firebox or roof without a camera, and it’s highly combustible. Out-of-neighborhood crews sometimes miss it entirely or use it to justify unnecessary full rebuilds. We show you exactly what we’re looking at.
- Draft imbalance from partial capping or relining. Capping or relining one flue in a multi-pot stack without accounting for the others changes the pressure balance. The boiler’s draft can pull air down the fireplace flue, causing smoke rollback into the living room or combustion spillage from the water heater. We inspect the whole stack, not just the flue that’s complaining.
Pricing for Chimney Liner & Rebuild in Forest Hills, NY
Here is what chimney liner and rebuild work costs in the Forest Hills market. These are the ranges we quote after inspection, with no-hassle upfront pricing - the number on the estimate is the number on the invoice.
| Service | Typical Range in Forest Hills |
|---|---|
| Stainless steel liner replacement (single flue, standard access) | $1,800 - $3,400 |
| Flexible liner with offset navigation | $2,200 - $4,100 |

| Multi-flue custom cap and capping system | $800 - $1,600 |
What moves the price: access height and scaffolding needs, the number of flues in the stack, whether the crown can be sealed or must be torn out and repoured, and the condition of the existing clay tile - intact tiles can sometimes be used as a form for a new liner, while collapsed tiles require more labor to remove. We don’t recommend any of this work without camera evidence you can see for yourself. Call (516) 531-6315 for an exact quote - estimates are free, and we carry a $50 discount on any repair over $250.

FAQs - Chimney Liner & Rebuild in Forest Hills
No, you don’t need to reline every flue simultaneously, but you must assess the draft balance across the entire stack before isolating any single flue. We were called to a 1925 Tudor on Greenway North in Forest Hills Gardens where the homeowner complained of a smoky fireplace and a damp smell in the attic. A Level 2 inspection with our camera revealed that the boiler flue had been relined years ago, but the adjacent fireplace flue was still unlined clay tile with spalling mortar joints, and the two shared a single multi-pot stack - so the boiler’s draft was pulling air down the fireplace flue. We installed a DuraFlex stainless steel liner in the fireplace flue, rebuilt the chimney crown with a flexible crown sealant, and capped all four pots with a custom multi-flue cap; the draft reversed correctly and the attic moisture disappeared within a week.

You know by looking at the camera footage, not by taking someone’s word. A Level 2 inspection with a chimney camera reveals cracked or missing clay tiles, spalling mortar joints, gaps between tile sections, or third-degree creosote buildup that no surface inspection can detect. In Forest Hills Gardens homes, we often find that the visible damage is worse than it appears because the century-old lime mortar has eroded behind the tiles. If the mortar is sound and only isolated tiles are cracked, a HeatShield resurfacing may suffice. If the mortar is compromised or multiple tiles are spalling, replacement is the honest recommendation - and we’ll show you exactly why. Call (516) 531-6315 for an exact quote - estimates are free.
Queens’ freeze-thaw cycles are harder on chimney crowns than steady cold would be. Water seeps into micro-cracks during rain or snowmelt, expands when it freezes, and widens the crack with every cycle. Forest Hills Gardens’ older homes often have original crowns poured without proper reinforcement, expansion joints, or overhang - they were built for coal draft, not modern weather exposure. We rebuild crowns with proper slope, drip edges, and flexible crown sealant or reinforced concrete that accommodates movement. A crown done right sheds water instead of absorbing it. Call (516) 531-6315 for an exact quote - estimates are free.
Third-degree creosote is a thick, glazed, tar-like deposit that forms when wood smoke condenses in a cool or poorly drafted flue. It’s highly combustible and burns at temperatures that can crack clay tiles or ignite surrounding structure. In older Forest Hills flues - especially unlined secondary flues left dormant after fuel conversions - the cool, stagnant air promotes condensation and creosote accumulation that goes unnoticed for years. It’s not visible from the firebox or roof without a camera, which is why out-of-neighborhood crews sometimes miss it entirely or misdiagnose it as grounds for an unnecessary full rebuild. We document it, show you, and recommend the right fix: mechanical removal, chemical treatment, or liner replacement depending on severity. Call (516) 531-6315 for an exact quote - estimates are free.
Yes, shared masonry systems in pre-war co-ops require coordinated access to multiple units and often to the building’s roof or mechanical spaces. Our technicians have worked with Forest Hills co-op boards and managing agents to schedule inspections that comply with building protocols and minimize disruption to residents. The inspection itself is still a standard Level 2 camera examination, but the logistics require experience with multi-unit buildings that single-family chimney crews may not have. We document findings for board review and provide written verdicts that satisfy insurance and warranty requirements. Call (516) 531-6315 for an exact quote - estimates are free.
