The short answer

EverSafe Chimney Sweep repairs chimneys in Boerum Hill's brownstones, rowhouses and pre-war buildings. We handle crowns, mortar joints, flashing leaks, dampers, caps and flue liners. Every repair starts with an inspection so you know the cause before any work begins.

Most chimneys in Boerum Hill rise from brownstones, brick rowhouses and pre-war apartment buildings. They have stood through many decades of freeze-thaw cycles, roof work and heating changes. EverSafe Chimney Sweep is based in Fort Greene, about a mile away, and our certified technicians repair chimneys throughout ZIP code 11201. We fix what we find, explain why it failed, and tell you plainly what can wait and what can't.

Why Chimneys in Boerum Hill Need Repair

Older brick chimneys in this neighborhood wear in predictable ways. Rain and snow soak into porous brick and mortar. When that water freezes, it expands and pushes the masonry apart. Over the years, joints open, faces of bricks flake off, and cement crowns crack. Once water gets past the top of the chimney, it can stain ceilings, rot framing near the roofline, and damage the flue from the inside.

Rowhouse chimneys are often built into shared party walls or sit close to a neighbor's stack. That can make a leak hard to trace. A stain on your top-floor wall may start at a cracked crown, failed flashing, or a gap between two roof sections. We look at the whole chimney and the roof around it before recommending a fix, so you aren't paying to patch the wrong spot.

Chimney Repairs We Handle

Most chimney problems fall into a handful of categories. We match the repair to the cause and use materials suited to older brick, which is often softer than modern brick.

  • Repointing: grinding out cracked or crumbling mortar joints and refilling them so water stops getting in
  • Crown repair or rebuilding: sealing hairline cracks, or replacing a crown that has broken apart
  • Flashing repair: resealing or replacing the metal where the chimney meets the roof, a common source of leaks
  • Spalled brick replacement: removing bricks whose faces have flaked away and setting new ones
  • Chimney caps: installing caps to keep out rain, birds and debris
  • Damper repair or replacement: fixing dampers that stick, won't close, or let cold air pour in
  • Flue liner repair and relining: addressing cracked clay tiles or installing a new liner

Oil-to-Gas Conversions and Flue Liners

Many Brooklyn buildings have switched their boilers from oil to gas. In New York City, the chimney has to be evaluated as part of that conversion. A new liner is often needed because gas exhaust produces acidic condensate. Over time, that condensate can corrode an unlined or poorly lined masonry flue.

If your building has converted, or a conversion is planned, we can inspect the flue and tell you whether the existing liner fits the new appliance. If it doesn't, we can explain the relining options. Doing this before the new boiler runs full time protects both the masonry and the people living above it.

Inspection First, Then Repair

The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year. Chimney professionals use three levels of inspection. A Level 1 inspection fits when nothing has changed. A Level 2 inspection is called for when the system changes, such as a new appliance or a switch of fuel, or when the home is sold. A Level 3 inspection is needed when a hidden hazard can only be reached by opening part of the chimney or building.

For repair work, we start with the inspection level that fits your situation. You'll get a clear explanation of what we saw, with photos where they help. We separate urgent safety issues from items you can plan for later.

Timing Repairs Around Heat Season

New York City's heat season runs from October 1 through May 31. During that period, building owners must keep apartments heated to the city's minimum temperatures. If you own a multi-unit building in Boerum Hill, a chimney problem that shuts down the boiler in January is far more disruptive than one fixed in late summer.

Masonry work also goes best in mild, dry weather. Scheduling repairs in late spring through early fall gives mortar and crowns time to cure. It also lets your heating system run without interruption once the season starts. We also serve nearby Downtown Brooklyn, DUMBO, Brooklyn Heights, Fort Greene and Clinton Hill.

FAQ

Common questions

How do I know if my chimney needs repair?

Common signs include water stains near the chimney, crumbling mortar, flaking brick faces, a cracked crown, rust on the damper, and bits of tile or masonry falling into the firebox. An inspection confirms the cause.

Can you repair a chimney that's shared with the house next door?

Often, yes. Party-wall chimneys are common in rowhouses. We look at how the stacks are built and explain what work affects your side and what may involve your neighbor.

Do I need a new liner if my building switched from oil to gas?

Not always, but often. Gas exhaust creates acidic condensate that can corrode a masonry flue. In New York City, the chimney has to be evaluated during an oil-to-gas conversion.

Is a leaking chimney always a masonry problem?

No. Many leaks come from failed flashing where the chimney meets the roof, or from a missing cap. We trace the water before recommending any masonry work.

When is the best time to schedule chimney repair?

Late spring through early fall is ideal. The weather suits masonry work, and the repair is finished before heat season starts on October 1.

Are your technicians certified?

Yes, our chimney technicians are certified, and they work on older brick chimneys across Brooklyn.
