We’ve worked Kensington’s row houses for over four decades. We know the 11218 zip code block by block, from the pre-war brick homes along Ocean Parkway to the attached two-stories near Cortelyou Road. These chimneys were built for coal, converted to oil or gas, and rarely relined. That history lives in your walls, and it shapes every cleaning we perform.
Why Hearthstone Chimney Co. of New York City Is Kensington’s Preferred Chimney Cleaning & Sweep Company
Our reputation in Kensington was built one neighbor at a time. In a neighborhood where attached houses share chimney stacks, word travels fast when a technician documents problems with photos, explains them in plain English, and fixes what he finds. We’ve earned that trust across 42 years of showing up when we say, pricing upfront with no surprises on the bill, and backing every job with our 90-Day Done Right Promise in writing.
Kensington customers tell us they chose us because we understand their housing stock. We’ve cleaned flues on East 5th Street, repointed crowns near Ditmas Avenue, and relined shared stacks around Avenue C. Our technicians are background-checked, uniformed, and carry professional-grade materials from DuraFlex, HeatShield, and Copperfield - no builder-grade substitutes that fail in Brooklyn’s freeze-thaw cycles.
Response time to Kensington is typically same-day or next-day during peak season. We don’t route trucks from distant depots. Our Brooklyn-based crews know the local streets, the parking realities, and the specific FDNY and NYC Buildings Department codes that govern chimney work in attached housing.
Frank Calucci founded this company in 1984 on a simple standard: Krafted right, Every time, Your home first, Standing behind it. That K.E.Y.S. code still governs how we treat every Kensington home.
Our Chimney Cleaning & Sweep Services in Kensington
Level 1 Inspection
A Level 1 inspection is the baseline for any chimney cleaning in Kensington. We examine readily accessible portions of your chimney structure, flue, and connections for soundness, freedom from deposits, and correct clearances. For many Kensington homeowners with recently serviced systems, this annual check confirms safe operation before the heating season begins. We document what we find and give you a plain-English verdict - no jargon, no scare tactics.
Level 2 Inspection
Level 2 inspections are where Kensington’s housing stock demands real expertise. We run a camera through every flue, photograph the liner condition, and map the shared-stack configuration that is standard in 11218 row houses. This is non-negotiable when you’re buying or selling, after a chimney fire, or when converting fuel types. On East 5th Street, a 1925 row house owner called us for a chimney cleaning and sweep after noticing smoke drifting from a disused fireplace. We found the old coal flue lined with original clay tiles cracked from freeze-thaw, and active migration into the adjacent unit. After a Level 2 inspection, we installed a DuraFlex stainless steel liner and cleaned the parlor flue, ending the cross-contamination hazard. Every Level 2 ends with photos you can see and a written verdict.
Creosote Removal
Brooklyn’s coastal humidity combined with hard freeze-thaw cycles each winter accelerates mortar joint failure and brick spalling on the exposed upper sections of Kensington’s chimney stacks, which rise just above low rooflines with little overhang protection. The cold, damp heating season drives heavy fireplace and boiler-flue use from October through April, compressing the annual creosote and soot buildup into a short, intense window. Stage 1 creosote brushes off clean. Stage 2 requires rotary chains. Stage 3, the glazed tar-like deposit, demands chemical treatment and mechanical removal. We assess what we’re dealing with before we quote, and we remove it completely.
Soot Removal
Soot accumulation in Kensington’s older flues often mixes with masonry debris from spalled brick and deteriorated mortar. We use professional-grade vacuums and rotary equipment to remove all deposits without contaminating your living space. For boiler flues that run hard all winter, this is essential maintenance that protects both efficiency and indoor air quality.
Annual Sweep
The National Fire Protection Association recommends annual inspection and cleaning for all chimney systems. In Kensington, we push that recommendation harder. Your 1920s chimney stack has endured a century of Brooklyn winters. The annual sweep is when we catch crown cracks before they become wall leaks, spot liner deterioration before it becomes a code violation, and clear abandoned flues before they become hazards. Schedule in September if you can. October through January fills fast.
Fireplace Cleaning
Parlor fireplaces in Kensington row houses were built for coal grates and later adapted for wood or gas logs. We clean fireboxes, smoke shelves, and damper assemblies, checking for proper draft and clearance to combustibles. Many original throat dampers are rusted open or sealed shut. We’ll tell you honestly whether cleaning suffices or if repair is the smarter path.

Trusted Brands We Service in Kensington
We stock and install professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. For Kensington’s relining needs, we keep DuraFlex stainless steel liners and HeatShield cerfractory flue sealant on our trucks, which means most liner repairs don’t require a return visit. Copperfield chimney caps and Gelco crown coatings handle the waterproofing that Brooklyn’s wet-freeze cycles demand. We don’t substitute builder-grade parts that fail in two seasons. The brands we use are the brands that last.
Common Chimney Cleaning & Sweep Problems We See in Kensington Homes
- Unlined or cracked clay-tile flues. When Kensington’s row houses converted from coal to oil or gas, the flues were rarely relined. Original clay tiles are now cracked from decades of thermal cycling, and NYC Buildings Department and FDNY codes mandate proper lining before active use. Every cleaning call here is almost always also a liner evaluation.
- Debris-choked abandoned flues adjacent to active ones. A single chimney stack may contain three or more flues - boiler, fireplace, former kitchen range. The unused ones fill with brick debris, animal nesting, and soot. Blocked venting creates backdraft hazards. Carbon monoxide doesn’t respect property lines.
- Deteriorated chimney crowns and spalled brick. Brooklyn’s wet-freeze cycles attack the exposed upper sections of these low-rising stacks. Water enters through crown cracks, freezes, expands, and spalls the brick face. The debris falls into flues. The cycle repeats until someone opens it up and fixes it right.
- Cross-flue contamination in shared party-wall stacks. Because Kensington row-house chimney stacks are built into shared party walls, a cracked or obstructed flue is never strictly one household’s problem - combustion gases and carbon monoxide can migrate laterally through compromised shared masonry into an adjacent neighbor’s home. This known failure mode often triggers block-level inspection calls, and a technician working on one address should expect a knock from next door before the day is done.

Because carbon monoxide and combustion gases migrate laterally through compromised shared masonry. A cracked liner in your flue can vent into an adjacent home, and vice versa. This is a documented hazard in attached row-house construction, which is why block-level inspection calls are common in Kensington. Our cleaning protocol includes checking shared-wall integrity. Call (855) 950-3861 to protect both households.
Brooklyn’s coastal humidity accelerates mortar deterioration and combines with freeze-thaw cycles to spall brick and crack crowns, increasing debris accumulation inside flues. The compressed heating season from October through April concentrates creosote and soot buildup. We recommend annual cleaning for all Kensington systems, and twice-yearly for heavily used fireplace and boiler combinations. Call (855) 950-3861 to set your schedule.
