The short answer
The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year, and Downtown Brooklyn homes are no exception. Most inspections are a Level 1 check, but a Level 2 is called for when you buy or sell a home, change fuel, or add a new appliance.
Downtown Brooklyn mixes newer apartment towers with pre-war apartment buildings, and brownstones and rowhouses sit at its edges, many with original masonry chimneys. Whether you have a working fireplace, a gas boiler venting through an old flue, or a chimney nobody has looked at in years, an inspection tells you what condition it is in before you rely on it. Our office in Clinton Hill is about a mile southeast of Downtown Brooklyn, so we schedule inspections here regularly.
Why Downtown Brooklyn Chimneys Need Regular Inspection
Many chimneys in and around Downtown Brooklyn were built for coal or wood and later adapted for oil or gas. Each change puts different stresses on the flue. Brick and mortar also take years of freeze-thaw cycles, water getting in at the crown, and settling in older party-wall construction. Problems like cracked flue tiles, loose bricks or a blocked flue are often invisible from the room below.
The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year. That applies whether you burn wood every weekend or the flue only serves a boiler or water heater you never see running.
Which Inspection Level Your Home Needs
Chimney professionals use three inspection levels. Our certified technicians will tell you which one fits your situation and why.
- Level 1: For a chimney that is in regular use and has not changed. We check the readily accessible parts of the chimney, the firebox or appliance connection, and the flue for obstructions and buildup.
- Level 2: For when something changes, such as a new appliance, a switch from oil to gas, or a home sale. This includes a camera inspection of the flue's interior and a look at accessible attic, basement and roof areas.
- Level 3: For when there is reason to suspect a hidden hazard that can only be reached by opening part of the chimney or the building. This is not routine. It is recommended only when a Level 2 finding points to it.
Oil-to-Gas Conversions and Older Flues
Many Brooklyn buildings have moved their boilers from oil to gas. When a New York City building converts 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.
If your building converted some time ago and the flue was never relined, or you are not sure what was done, a Level 2 inspection with a camera can show the condition of the flue interior. We will explain what we see and whether a liner is worth considering. You decide what to do next.
Time for your annual chimney check?
Timing Your Inspection Around Heat Season
New York City's heat season runs from October 1 through May 31. During that time, building owners must keep apartments heated to the city's minimum temperatures. If your heating system vents through a chimney, finding a problem in November can mean a rushed repair while tenants or family need heat.
Late spring and summer are practical times to inspect. The system is off or running lightly, and there is time to plan any repairs before October. For fireplaces, an inspection before you light the first fire of the fall is a sensible habit.
What to Expect During the Visit
We protect the area around the fireplace or appliance, examine the chimney from the inside and, where safe access is available, from the roof. For a Level 2 inspection, we run a camera through the flue and record what we find. Afterward, we walk you through the results in plain terms. That includes what is fine, what should be watched, and what needs attention now.
We also serve homes in nearby DUMBO, Brooklyn Heights, Boerum Hill, Fort Greene and Clinton Hill. Many of these have the same mix of brownstones, rowhouses and pre-war buildings found in Downtown Brooklyn.
