The short answer

GoldenFlue Chimney Services repairs chimney masonry, crowns, flashing, caps and flue liners for Borough Park homes and small buildings. We start by finding the cause of the damage, then recommend the repair that fits your chimney, including liner work after an oil-to-gas boiler conversion.

Borough Park's housing includes attached brick rowhouses, semi-detached and detached homes, and small multifamily and pre-war apartment buildings. Many of these chimneys serve a boiler or furnace rather than a fireplace, share walls with neighbors, and work hard every winter. GoldenFlue Chimney Services repairs chimneys throughout Borough Park (ZIP 11219) from our office in Bay Ridge, about two miles away. Our certified technicians find out why a chimney is failing, explain what they found in plain terms, and repair the cause instead of covering up the symptom.

Chimney Problems We Commonly Find in Borough Park

Brick chimneys on older Brooklyn homes take a beating from rain, snow and repeated freezing and thawing. Water that soaks into worn mortar or a cracked crown expands when it freezes, and over several winters that loosens brick and opens gaps. Chimneys that vent boilers have another problem: exhaust gases can leave moisture and acidic residue inside the flue.

These are the repairs Borough Park homeowners call us about most:

  • Repointing crumbling or missing mortar joints
  • Replacing cracked, flaking or spalled brick
  • Rebuilding or resealing a cracked chimney crown
  • Repairing or replacing flashing where the chimney meets the roof
  • Installing or replacing chimney caps to keep out rain, birds and debris
  • Relining or repairing deteriorated clay or metal flue liners
  • Fixing damaged dampers and smoke chambers on working fireplaces

Boiler Flues, Oil-to-Gas Conversions and Liners

Many Borough Park buildings heat with a boiler that vents through a masonry chimney. When a New York City building converts its boiler from oil to gas, the chimney has to be evaluated as part of the work. A new liner is often needed, because gas exhaust produces acidic condensate that can corrode a masonry flue that was built for oil.

If you are planning a conversion, have already converted, or notice stains, crumbling material at the base of the flue, or loose tiles in the cleanout, we can inspect the flue and tell you whether it needs a liner sized for your new appliance. Bringing the chimney into the plan early helps keep a conversion on schedule.

How a Chimney Repair Visit Works

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

After the inspection, we walk you through what we found, show you the problem areas, and explain your options. On attached homes, we also look at how the chimney meets shared walls and neighboring roofs, since water and damage often travel along those joints. We then schedule the work and keep the area as clean as we can while we repair it.

Planning Repairs Around Heat Season

New York City's heat season runs from October 1 through May 31, and during that time building owners must keep apartments heated to the city's minimum temperatures. If you own a multifamily building, a chimney problem that forces the boiler off in January is far harder to handle than one fixed in late summer.

We recommend scheduling inspections and planned repairs in the warmer months whenever possible, so liners, crowns and masonry are ready before the heating season starts. If something goes wrong in the middle of winter, contact us and we will help you work out the safest next step.

What to expect

How a visit goes

  1. We find the cause first

    A leak, a draft problem or a smoky room can have several causes. We track down the actual source before suggesting a repair, so you are not paying for work that does not solve it.

  2. We show you what we see

    Most of a chimney is out of sight. We photograph the flue, crown, flashing and cap so you can see the condition for yourself and decide with full information.

  3. We keep your home clean

    We cover floors and furniture near the work area, contain soot and debris, and clean up before we leave.

FAQ

Common questions

How do I know my chimney needs repair?

Common signs include loose or crumbling mortar, flaking brick, water stains on ceilings or walls near the chimney, rust on the damper or cap, and pieces of tile or masonry falling into the firebox or cleanout. An inspection will confirm the cause.

Does my chimney need a new liner after converting my boiler from oil to gas?

Often, yes. In New York City, the chimney has to be evaluated during an oil-to-gas conversion, and a new liner is frequently needed because gas exhaust creates acidic condensate that can corrode a masonry flue.

How often should my chimney be inspected?

The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year. A yearly inspection helps catch small problems before they turn into larger repairs.

Can you repair a chimney on an attached rowhouse?

Yes. We regularly work on chimneys in attached homes and pay close attention to shared walls, flashing and the joints where neighboring roofs meet the chimney.

When is the best time to schedule chimney repair?

Late spring and summer are ideal, since repairs are finished before New York City's heat season begins on October 1. For building owners, that timing reduces the risk of a boiler shutdown in winter.

Are your technicians certified?

Yes, our chimney repair work is performed by certified technicians who explain their findings and recommendations before any work begins.
