The short answer
Brooklyn Heights chimneys should be inspected once a year, as the NFPA 211 standard recommends, and again whenever you change appliances or fuel, or buy or sell the home. Our certified technicians come from nearby Clinton Hill to inspect brownstones, rowhouses and pre-war buildings at the level the situation calls for.
Many Brooklyn Heights homes have masonry chimneys that have been working for generations. That includes brownstones and rowhouses with several fireplaces stacked floor over floor, and pre-war apartment buildings with boiler flues running up through the building. Age, weather, past renovations and fuel changes all leave marks that are hard to see from the hearth or the roof. Our certified technicians inspect chimneys in Brooklyn Heights from our office in Clinton Hill, about 2 miles away. We tell you plainly what condition your chimney is in and what, if anything, needs attention.
What We Check in a Brooklyn Heights Chimney
Older brownstones and rowhouses often have more than one flue in the same chimney stack. Some serve working fireplaces, some are sealed off, and some were taken over by a furnace or water heater during a later renovation. We start by working out which flue serves what, because the right questions depend on how each one is used.
From there we look at the parts of the system that can be reached without opening any walls.
- Firebox, damper and smoke chamber for cracks, gaps and creosote buildup
- Flue liner condition, including missing or damaged sections of clay tile or metal liner
- Blockages from nests, fallen masonry or debris
- Chimney crown, cap and flashing where they can be safely seen
- Signs of water entry, such as staining, spalling brick or rust on the damper
- Connections from boilers, furnaces or water heaters into the chimney
Choosing the Right Inspection Level
The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year. Chimney professionals use three inspection levels, and we match the level to your situation rather than defaulting to the most involved one.
A Level 1 inspection fits when nothing about the system has changed and you keep using it the same way. A Level 2 inspection is called for when the system changes, such as a new appliance or a switch of fuel, and when the home is sold. In Brooklyn Heights that often means buyers and sellers of brownstones and co-op or condo units in older buildings. A Level 3 inspection is needed only when a suspected hidden hazard can't be reached without opening part of the chimney or building. We explain why before recommending one.
Oil-to-Gas Conversions and Liners
Many pre-war buildings and some townhouses in Brooklyn Heights have moved, or are planning to move, from oil heat to gas. 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.
If you are planning a conversion, an inspection before the work starts gives you and your heating contractor a clear picture of the existing flue. If the conversion has already happened, we can check whether the liner suits the new appliance and whether the masonry shows signs of condensate damage.
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. For anyone who owns or manages a building with a boiler, a chimney problem found in January is far more disruptive than one found in August.
We suggest scheduling inspections in late spring or summer when you can. That leaves time to arrange any repairs or relining before the boiler has to run all winter. Homeowners who use their fireplaces in cold months benefit from the same timing, because fireplaces see the heaviest use once the weather turns.
Serving Brooklyn Heights and Nearby Neighborhoods
Our office in Clinton Hill is a short trip from Brooklyn Heights, so scheduling is straightforward. We also inspect chimneys in Downtown Brooklyn, DUMBO, Boerum Hill, Fort Greene and Carroll Gardens. The housing in those areas is similar: rowhouses, brownstones and pre-war apartment buildings with shared or stacked flues.
After every inspection we walk you through what we found, show you photos where possible, and separate urgent safety issues from items you can plan for later.
