Chimney Sweeps & Masons For Brooklyn's Rowhouses — Around The Clock

A century of coal, oil and gas has moved through this borough's flues, and most of them have outlived the people who built them. From our shop on 5th Avenue we sweep, reline and repoint the stacks of Park Slope brownstones, Bed-Stuy rowhouses and everything with a chimney in between — at whatever hour the problem announces itself.

  • A human answers at every hour
  • COIs for co-op & condo buildings
  • Rowhouse & party-wall flue experience

What We Do

Borough Chimney Work, Firebox To Cornice

Brooklyn chimneys are their own trade — shared stacks, landmark facades, boilers venting through Victorian flues. This is the work our vans do every day, and every night the borough asks for it.

Rowhouse & Brownstone Sweeping

Old flues shed mortar, soot and the occasional pigeon nest into narrow, crooked runs. We rod them full length with the fireplace sealed off and a filtered vacuum protecting the parlor floor.

  • Full-length rodding of narrow pre-war flues
  • Original mantels & woodwork protected
  • Containment sealed before the first rod

Inspections That Cost Nothing

The tech works the entire system and tells you the verdict on the spot, free, at any hour. Need the findings as a document with photos — for a board, a closing, a claim? That version is $149.

  • The look and the verdict: always $0
  • Documented report for boards & closings: $149
  • Boiler and gas flues covered too

Rebuilds Above The Roofline

A hundred winters of freeze and thaw will bring any stack to its knees. We rebuild from the flashing up in brick that honors the streetscape — because on a Brooklyn block, the roofline is public property.

  • Tear-down to sound courses, relaid plumb
  • Brick matched to century-old neighbors
  • Crowns poured to shed water properly

Brownstone & Brick Repointing

Joints on a pre-war facade fail quietly, then all at once. Our masons cut out the dead mortar and repoint with mixes soft enough for old brick and brownstone — the hard modern stuff destroys both.

  • Lime-rich mortars for pre-war masonry
  • Color struck to match the existing joints
  • Chimney backs & party walls included

Caps, Crowns & Cover Plates

An open flue in this city collects rain, soot fall and pigeons in roughly equal measure. Stainless caps, poured crowns and fitted cover plates close the top without strangling the draft.

  • Screened stainless caps, single or multi-flue
  • Cover plates for decommissioned flues
  • Crack-sealed or fully re-poured crowns
Cap the stack

Leak & Flashing Work

When water shows up two floors below the roof, the chimney is the first suspect. We follow the trail to the actual breach — flashing, crown or brick face — and close it for good, not for one season.

  • Diagnosis before any dollar is quoted
  • Metal flashing formed & woven in right
  • Breathable repellents, never trap-coatings

Liners For Fireplaces & Boilers

Half the borough's boilers exhaust through flues built for coal grates. Insulated stainless liners bring those runs up to code and keep carbon monoxide moving in the only acceptable direction: out.

  • Boiler & water-heater flue relining
  • Insulated stainless for wood fireplaces
  • Sized to the appliance, installed to code

Hearth & Firebox Renewal

Sealed-up fireplaces reopened, tired fireboxes relaid, dead flues brought back to life — the fireplace a listing calls "decorative" can very often burn again, done properly and checked first.

  • Decommissioned fireplaces re-commissioned
  • Firebrick relays & smoke chamber parging
  • Hearths & surrounds rebuilt clean

Worth Your Attention

Seven Things A Brooklyn Chimney Does Before It Fails

In houses this old, the difference between a service call and a gut repair is usually just who noticed first.

  • A fireplace that breathes into the roomDraft reversal — blockage, damper or a flue too tired to pull. CO risk in the same breath.
  • Mortar dust on the top-floor closet shelfInterior flue joints are letting go inside the wall cavity — a classic rowhouse tell.
  • A neighbor's smoke in your apartmentParty-wall flues cross-talking. Common in attached houses, never acceptable.
  • Damp arcs on a top-floor ceilingThe stack is drinking rain — cap, crown or flashing has surrendered.
  • Black glaze lining the flueThird-stage creosote — chimney-fire fuel. The fireplace is done until it's cleared.
  • Brick shards in the airshaft or yardThe stack is spalling from the top down. Gravity finishes what water starts.
  • A boiler flue no one has ever openedIf the house predates the war and nobody remembers a cleaning, assume it needs one.

Asked & Answered

Brooklyn Chimney Questions, Without The Runaround

The inspection costs nothing — where's the catch?

There isn't one, but there is an asterisk, and here it is in plain terms: a tech examines the entire system and tells you exactly what was found, free, at any hour. If those findings need to become a document — photographs and written conclusions that a co-op board, closing attorney or insurance adjuster will accept — the documented report costs $149. The spoken version and the paper version describe the same chimney; only one of them is billable.

Is someone truly picking up at 3 AM?

Truly. This borough heats through the night — boilers push exhaust up hundred-year-old flues while everyone sleeps, which is exactly when a blocked run turns dangerous. The number reaches a person around the clock, and real emergencies get a van, not a callback window.

Our rowhouse chimney hasn't been serviced in living memory. Now what?

Join the club — half our calls start that sentence. Pre-war flues are often bare brick or cracked terracotta doing modern work they were never designed for. Since looking costs nothing here, the sensible move is obvious: have it examined before the heating season leans on it, and decide from facts instead of hope.

The chimney is shared with the house next door. Whose problem is it?

Structurally, often both of yours — party-wall stacks carry flues from attached houses side by side. We scope the runs to establish which flue serves which building, then split the diagnosis honestly. Where repairs touch shared masonry, we'll walk both owners through it so the cost lands where it belongs.

Our managing agent demands a COI. Can you provide one?

Routinely. Liability and workers' comp are current, and certificates naming your building go out by email before the visit — most Brooklyn co-ops and condos won't unlock roof access without one, so we treat it as a standard step, not a special request.

How messy does a sweep get in a finished parlor?

It doesn't. The opening is sealed under containment before any rod moves, runners guard the floors, and a filtered vacuum stays on the whole visit. Original mantels and surrounds get wrapped. About an hour later, the only evidence is a clean flue.

I'm in contract on a brownstone. Should the chimney be checked before closing?

Emphatically yes — general home inspectors look at a chimney; they don't look inside it. For a purchase you'll want the $149 documented report, since nobody at a closing table acts on a verbal opinion. It's a small line item against a six-figure decision, and it has re-priced more than one deal.

What qualifies as "call right now" instead of "book this week"?

Smoke or exhaust entering living space, any suspected flue fire even if it seems out, brick falling from the stack, water actively coming through, or animals trapped in the run. Say "emergency" when you call (929) 560-2437 and dispatch treats it that way. Active flames or suspected carbon monoxide in the home? Everyone out first, 911 first — we're the second call.
