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.

We’ve been dispatching crews to East Harlem from our New York City office for decades. We know the five- and six-story pre-war tenements along Lexington Avenue, the masonry stacks on Park Avenue, and the boiler-room configurations below buildings on Third Avenue. These chimneys were built for coal, converted to gas or oil, and now vent appliances they were never engineered to handle. That history matters when we’re inside your flue with a camera. Our Chimney Cleaning & Sweep team doesn’t guess at what’s wrong. We document it, show you the photos, and tell you plainly what needs doing now, what can wait, and what doesn’t need doing at all.
Why Hearthstone Chimney Co. Is East Harlem’s Preferred Chimney Cleaning & Sweep Company
East Harlem homeowners call us back because we treat their buildings like the permanent homes they are. Over 42 years, we’ve learned that a pre-war tenement chimney on East 116th Street or Pleasant Avenue isn’t a commodity job. It’s a specific structure with specific failure modes, and the technician who doesn’t know the difference between a coal-era flue and a modern liner is the technician who recommends work you don’t need.
Our Level 2 inspections end with dated photos and a plain-English verdict - no jargon, no scare tactics. If the flue is sound, we say so. If a clay-tile partition between shared flues has cracked, we show you the image, explain the NYC Building Code requirement, and handle the notification ourselves. The 90-Day Done Right Promise covers every job in writing: if it’s not right, we make it right, no paperwork and no arguing.
A live person answers our phones 24 hours a day, 7 days a week. Not a voicemail. Not an app. Not a callback queue. Background-checked, uniformed technicians arrive when scheduled, and most East Harlem sweeps and inspections are completed in a single visit. No-hassle upfront pricing means the estimate number matches the invoice number. We’ve been at this since 1984, and we plan to be here in thirty more years. That changes how you treat every customer.
Our Chimney Cleaning & Sweep Services in East Harlem
Level 1 Inspection
A Level 1 inspection is the visual examination required annually for chimneys in regular service. In East Harlem’s older tenements, we use this baseline check to assess accessible portions of the fireplace, chimney structure, and flue - but we’re candid about its limits. If your building has a shared chimney chase with multiple flues, or if the service history is unknown, a Level 1 won’t reveal cracked partitions or deteriorated liners hidden inside the masonry. We’ll tell you when a Level 2 is the smarter starting point.
Level 2 Inspection
This is where our East Harlem work gets specific. A Level 2 inspection includes a full camera scan of the flue interior, accessible attics, basements, and crawl spaces. For East Harlem tenements with coal-era chimney stacks now venting gas boilers, this is often essential. We were called to a pre-war tenement on East 116th Street where a basement boiler had been vented into a flue originally sized for a coal stove. The draft was so weak that combustion gases were spilling back into the boiler room. A Level 2 inspection with our camera revealed a cracked partition between that flue and an adjacent apartment’s flue, so we stopped work, notified the NYC Department of Buildings as required, and returned after repairs to sweep and apply a HeatShield liner.
Every Level 2 in East Harlem produces photos you can see and a written verdict you can understand. Nothing is recommended without camera evidence. That’s the rule.
Creosote Removal
East Harlem’s older chimneys, especially those with oversized flues and weak drafts from mismatched appliances, tend to accumulate creosote unevenly. First-degree creosote - flaky, sooty, easily brushed - is what most annual sweeps address. Second-degree creosote forms puffy or honeycomb deposits, often from restricted airflow. Third-degree creosote, or glaze, is a hardened, tar-like coating that can’t be brushed away in a standard sweep and requires specialized treatment.
We don’t upsell. If your East Harlem flue has first-degree creosote, we sweep it. If we find third-degree glaze during inspection, we show you the camera image and explain the difference. Chemical treatment or rotary removal is only recommended when the evidence supports it. A standard creosote removal in East Harlem runs $189 to $289; third-degree glaze treatment starts at $349.
Soot Removal
Soot accumulation in East Harlem tenements often signals a combustion problem, not just a cleaning need. Poor draft from an oversized flue, a blocked cap, or a mismatched appliance can produce excessive soot that coats the flue and reduces clearance. Our sweep includes soot removal as standard, but we also flag the cause. If your boiler or fireplace is producing more soot than it should, we’ll document it and recommend the right fix - not just the repeated cleaning that treats a symptom.
Annual Sweep
For East Harlem buildings with active fireplaces or gas boilers venting through original masonry chimneys, an annual sweep is the baseline maintenance that keeps warranties valid and insurance requirements satisfied. Our annual sweep includes full debris removal, firebox and damper check, exterior masonry visual assessment, and a condition report. We schedule East Harlem annuals before burning season, because once the temperature drops and freeze-thaw cycles accelerate, minor mortar damage becomes major liner fractures fast.
Fireplace Cleaning
Fireplace cleaning in East Harlem focuses on the firebox, smoke chamber, and damper assembly - the components that see direct use. In pre-war tenements with original fireplaces now used for supplemental heating or ambiance, we check for deteriorated firebrick, damaged throat dampers, and smoke chamber parging that has cracked with age. Cleaning restores function and appearance; inspection reveals what age has compromised.

Trusted Brands We Service in East Harlem
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney - brands specified by engineers for liner restoration, crown repair, and cap replacement. For East Harlem tenements with damaged flue partitions or deteriorated clay liners, HeatShield cerfractory sealant and DuraFlex stainless liners are the repairs that last, not the builder-grade substitutes some operators install to keep bids low. We stock common sizes and configurations for faster turnaround on East Harlem jobs, because a boiler down in January is not a waiting situation.
Common Chimney Cleaning & Sweep Problems We See in East Harlem Homes
- Cracked partitions between shared flues. East Harlem tenements often contain multiple flues for different apartments or former coal appliances within a single chimney chase, separated only by thin brick or terra cotta partitions. Cleaners frequently find those partitions cracked or collapsed, allowing combustion gases to cross between flues. This is a NYC Building Code violation that mandates immediate notification of the NYC Department of Buildings and stops any relighting of the connected boiler.
- Freeze-thaw mortar destruction on flat-roof stacks. Manhattan’s repeated freeze-thaw cycles - temperatures crossing 32°F many times each late-autumn and early-spring season - aggressively attack the exposed mortar joints and brick faces of East Harlem’s flat-roofed tenement chimney stacks. Missing or deteriorated chimney caps, common on deferred-maintenance buildings in the neighborhood, accelerate water infiltration that fractures clay flue liners between annual cleaning visits.
- Upsold relines based on firebox glances, not camera evidence. The defining scam in East Harlem chimney work is recommending a full reline based on a visual look at the firebox without camera documentation, when the real issue is often a cracked partition between shared flues in the same chase. A proper Level 2 inspection reveals the actual problem and protects the homeowner from unnecessary expense.
- First-degree creosote sold as third-degree glaze. Some operators treat routine flaky creosote as hazardous glaze, pushing chemical treatments a standard sweep would handle. We show you the camera image and explain what we’re seeing. If it’s first-degree, we sweep it. If it’s glaze, we document it and discuss real options.

FAQs - Chimney Cleaning & Sweep in East Harlem
Most pre-war East Harlem tenements have chimney chases with multiple flues separated by thin brick or terra cotta partitions, and a standard visual sweep cannot detect cracked or collapsed partitions that allow combustion gases to cross between apartments. A Level 2 inspection with internal camera documentation is the only method that reveals these hidden conditions, which are both a safety hazard and a NYC Building Code violation. If your building has never had a camera inspection, or if the service history is unknown, we recommend starting with Level 2. Call (516) 206-6672 to schedule - estimates are free.
Active fireplaces and gas boilers venting through original masonry chimneys in East Harlem should be swept and inspected annually, ideally before the heating season begins. The neighborhood’s freeze-thaw cycles, combined with aging clay liners and shared flue configurations, mean that conditions can deteriorate significantly within a single year. Annual documentation also satisfies insurance requirements and establishes a baseline for tracking changes. Call (516) 206-6672 to book your annual - we’ll remind you next year.
Third-degree creosote, or glaze, is a hardened, tar-like coating that forms when combustion byproducts condense and bake onto the flue wall over repeated heating cycles. Unlike flaky first-degree or puffy second-degree creosote, glaze adheres tenaciously and cannot be removed with standard brushes. In East Harlem’s oversized, slow-drafting flues, glaze formation is more common because exhaust gases linger longer and cool faster. Removal requires specialized rotary equipment or chemical treatment, followed by verification that the flue is clean and properly sized. We never recommend glaze treatment without camera evidence showing you exactly what we’re seeing. Call (516) 206-6672 for an inspection and honest assessment.
Yes, under specific conditions. When a cracked or collapsed partition between shared flues in a multi-unit East Harlem tenement allows combustion gases to cross between flues, this constitutes a hazardous condition under NYC Building Code that mandates immediate notification to the NYC Department of Buildings and prohibits relighting the connected appliance until repairs are completed. We handle this notification as part of our service. For single-flue, single-family conditions, reporting requirements differ. We explain exactly where your situation falls and what steps follow. Camera evidence determines the finding; we show you before any report is filed. Call (516) 206-6672 with questions about your specific building.
A missing or damaged chimney cap matters significantly in East Harlem, where freeze-thaw cycles destroy mortar joints and water infiltration fractures clay liners between annual visits. The cap is the primary defense against rain, snow, and debris entering the flue. Without it, water pools on the smoke shelf, accelerates liner deterioration, and creates the damp conditions where creosote forms more aggressively. During every sweep and inspection, we assess cap condition and recommend replacement when needed, using Gelco or Olympia Chimney caps sized for your specific flue. A proper cap installation in East Harlem typically runs $189 to $349 depending on access and flue configuration. Call (516) 206-6672 for an exact quote.
