Fast, Reliable Chimney Cleaning & Sweep Across Kensington
A professional chimney cleaning and sweep in Kensington, NY typically costs between $180 and $450 depending on your flue condition, and most jobs are completed same-day with Paul Torres on-site. If you live in one of Kensington’s century-old brick row houses along Ocean Parkway or Cortelyou Road, your chimney likely started life venting coal and was later converted for gas—often without a properly sized liner. That’s exactly the scenario our Chimney Cleaning & Sweep team handles every week in the 11218 ZIP code.
We’re on familiar ground in Kensington. Paul Torres has spent 14 years working Brooklyn’s prewar housing stock, and the neighborhood’s 1900s–1920s attached and semi-detached brick rows hold no surprises for us. From Albemarle Road to Ditmas Avenue, we know which blocks have shared party-wall chimneys, which flues were converted without liners, and how the freeze-thaw cycles along Brooklyn’s southern edge chew through century-old mortar. Call (833) 349-5892 for a free estimate—Paul leads every job personally.
Why Legacy Chimney Cleaning New York Is Kensington’s Preferred Chimney Cleaning & Sweep Company
Our reputation in Kensington is built on showing up and doing the work right, not sending subcontractors. Paul Torres is the owner and the lead technician on every sweep, inspection, and repair. That means when you book a chimney cleaning on East 8th Street or near the Parade Grounds, the person with 14 years of documented experience—and 1,119 verified reviews averaging 4.7 stars—is the one on your roof, not a rotating hire.
We’ve earned those reviews by solving problems that cut-rate sweeps miss. In Kensington’s tightly packed row house blocks, many chimneys are party-wall construction shared between two adjoining properties. A collapsed flue tile or failed liner can simultaneously leave both neighbors’ gas boilers venting combustion gases into living spaces, yet typically only one owner calls for service, leaving the adjacent unit’s carbon monoxide risk unaddressed. Paul has flagged this exact hazard on dozens of Kensington jobs, and our customers remember the call that potentially saved a life.
Response time to Kensington is same-day or next-day for standard sweeps, and we carry the inspection equipment and professional-grade materials—DuraFlex liners, HeatShield resurfacing systems, Famco caps—so we’re not making return trips for parts. From the sweep to the rebuild, one crew, one accountability chain.
Our Chimney Cleaning & Sweep Services in Kensington
Level 1 Inspection
A Level 1 inspection is the visual check we perform during every standard sweep, and for Kensington’s well-maintained gas fireplaces with recent service history, it’s often sufficient. Paul examines the readily accessible portions of your chimney exterior, interior, and appliance connection for obstructions, soot buildup, and structural soundness. In a neighborhood where many flues haven’t been professionally inspected since the 1980s gas conversion boom, even this baseline check frequently turns up surprises—crumbling crowns, missing caps, or deteriorated mortar that the homeowner never noticed from the street.
Level 2 Inspection
This is where Kensington’s housing stock demands we spend real time. A Level 2 inspection includes video scanning of the flue interior, and in 11218’s unlined masonry chimneys converted from coal to gas, it’s often non-negotiable. We ran a Level 2 on a 1922 semi-detached on Ocean Parkway where the homeowner’s gas boiler was backdrafting. Inside, we found a shared flue with the neighbor’s unit—their furnace was also tied in, and only one had called. We recommended a HeatShield liner for both sides to separate the flues and restore draft. Without that camera inspection, the shared hazard stays invisible. If your Kensington row house hasn’t had a video scan in the last five years, book one.
Creosote Removal
Creosote accumulation in Kensington poses a specific challenge: the neighborhood’s wide-bore, unlined masonry flues—originally built for coal—create turbulent airflow when converted to gas, producing more incomplete combustion byproducts than a properly sized liner would. That sticky, flammable creosote coats the rough interior brick and collects in hidden voids where deteriorating lime mortar joints have opened gaps. A standard brush pass from a cut-rate sweep might clear the center channel and leave the buildup in those voids. Our creosote removal uses rotary power sweeping matched to your flue diameter, followed by camera verification that the brick is actually clean, not just brushed-over.
Soot Removal
Soot removal sounds straightforward until you’re working in a flue that’s been shedding mortar into the void for sixty years. In Kensington’s prewar chimneys, we regularly find soot packed behind spalled brick faces and in the gaps where original parging has collapsed. That soot restricts airflow, worsens backdrafting, and can harbor moisture that accelerates freeze-thaw damage through Brooklyn’s winters. We remove soot comprehensively, not cosmetically, because in these century-old structures, what’s hidden behind the surface often matters more than what’s visible.

Trusted Brands We Service in Kensington
We don’t install big-box generics in Kensington chimneys. For liners and resurfacing, we specify DuraFlex stainless-steel liners and HeatShield cerfractory resurfacing systems—materials designed for the exact conditions we find in 11218’s oversized, unlined masonry flues. For caps, dampers, and repair components, we source Famco and Copperfield hardware that fits properly and lasts. We stock common sizes for Kensington’s typical flue dimensions, so most installations don’t require a two-week parts wait. Professional-grade materials, properly installed, by Paul Torres on every job.
Common Chimney Cleaning & Sweep Problems We See in Kensington Homes
- Crumbling lime mortar joints in unlined chimneys let creosote and soot accumulate in hidden voids between bricks, making a standard brush sweep ineffective and requiring a Level 2 inspection with a camera. We find this on roughly half the Kensington sweeps we perform.
- Oversized flues converted for gas cause chronic backdrafting; soot and creosote from incomplete combustion cling to the wide bore, and a standard sweep without relining often fails to stop the recurrence. The fix isn’t more sweeping—it’s a properly sized DuraFlex liner.
- Party-wall chimney failures often go unreported on one side: if a flue collapses, only the calling homeowner’s appliance is serviced, leaving the neighbor’s gas vent path compromised and undetected. We’ve had to gently suggest that the attached neighbor call us too—more than once.
- Freeze-thaw damage destroys crowns and caps that predate modern waterproofing standards. Brooklyn’s winter temperature swings are especially brutal to Kensington’s unreinforced century-old brick chimney tops, and a cracked crown lets water infiltrate that accelerates everything else.

FAQs — Chimney Cleaning & Sweep in Kensington
Backdrafting in Kensington’s row houses almost always traces to an oversized, unlined masonry flue that was built for coal and never properly resized for your gas boiler. The wide bore creates weak draft, especially in cold weather, and combustion gases spill into your basement instead of rising through the chimney. A Level 2 inspection with video scanning confirms the diagnosis, and a properly sized stainless-steel liner—typically DuraFlex—usually solves it permanently. Call (833) 349-5892 for an exact quote; estimates are free.
Yes, and here’s why: in Kensington’s party-wall construction, your flue and your neighbor’s flue often share the same masonry structure, and a failure on one side can vent carbon monoxide into the other home even if that neighbor’s appliance appears to work fine. We inspect both sides when we can gain access, but if your neighbor hasn’t called, their gas vent path may be compromised and undetected. We’ve found shared flues where both furnaces were tied into a single collapsed tile liner—neither household knew. Talk to your neighbor, or have Paul explain the situation when he’s on-site.
A Level 2 inspection is a video-scanned evaluation of your flue’s interior, required when you’re buying or selling a home, after a chimney fire, or when you’re changing appliance types—and in Kensington, we recommend it for any row house that hasn’t had a camera inspection in the last five years. The 11218 ZIP code’s century-old unlined chimneys hide deterioration that a visual Level 1 check simply can’t catch: missing mortar, spalled brick, creosote in voids, and shared flue conditions. Call (833) 349-5892 to schedule; Paul Torres performs every scan personally.
We can sweep it, but we won’t just sweep it and leave. A crumbling crown lets water into the chimney structure, and in Kensington’s freeze-thaw climate, that water destroys mortar from the outside while your flue deteriorates from the inside. Paul will complete the sweep, show you the crown damage on camera, and quote crown repair or replacement—often using Copperfield or Famco components—before the next winter cycle makes it worse. Estimates are free.
Party-wall chimneys in Kensington require inspecting both sides of the shared structure, documenting conditions for both properties, and often negotiating access with an attached neighbor. The masonry is more complex, the liability exposure is higher, and the fixes—like separating shared flues with individual HeatShield or DuraFlex liners—are more involved than a standalone chimney. You’re paying for thoroughness that protects two households, not just a brush pass. Call (833) 349-5892 and Paul will walk you through exactly what’s involved for your specific building.
