This page covers what we see most often in Bensonhurst homes and how we can help keep your chimney and vents safe and working through each Brooklyn season.
Chimneys in Bensonhurst Homes
Bensonhurst has attached brick rowhouses, two-family homes, some detached houses and pre-war apartment buildings. Many of these buildings have masonry chimneys that have worked for decades. Some still serve a fireplace. Many more vent a boiler or water heater, and owners rarely look at them until something goes wrong.
In attached homes, the chimney often runs up a party wall or rises close to a neighbor's roof. That makes the condition of the crown, flashing and mortar joints important. Small cracks let in water, and water damage can spread inside the wall before anyone sees it. We look at the whole system, from the appliance or firebox up to the top of the flue. Then we explain what we found in plain terms.

How Brooklyn Weather Wears Down Masonry
Southern Brooklyn gets humid summers, wet springs, and winters that swing above and below freezing. Each freeze-thaw cycle works water deeper into porous brick and old mortar. Damp air near the water adds to the moisture load. Over time this shows up as loose or missing mortar, flaking brick faces, rusted dampers and stains on ceilings or walls near the chimney.
Keeping water out is the best way to slow this damage. Depending on what the chimney needs, that can mean:
- A chimney cap to keep rain, debris and animals out of the flue
- A chase cover for framed chimneys that have a metal top
- Waterproofing for exposed brick, using a breathable product made for masonry
- Repointing or crown repair where mortar has failed
- Rebuilding the upper courses of a chimney when the damage is too far along to patch
Heat Season, Boilers and Liners
New York City's heat season runs from October 1 through May 31. During those months, building owners must keep apartments heated to the city's minimum temperatures. For many Bensonhurst owners with rental units, a boiler that cannot vent safely is an urgent problem. Late summer and early fall are good times to have the chimney checked, before the heating system runs every day.
When a New York City building converts its boiler from oil to gas, the chimney has to be evaluated as part of the job. A new liner is often needed. Gas exhaust produces acidic condensate, and that condensate can corrode an unlined or poorly lined masonry flue. We can inspect the flue and install a liner that fits the new appliance.
The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year. A Level 1 inspection fits when nothing has changed. A Level 2 inspection is used when the system changes, such as a fuel switch or new appliance, or when a home is sold. A Level 3 inspection is for cases where a hidden hazard can only be reached by opening part of the chimney or building.

Dryer Vents and Air Ducts
In tight rowhouses and multi-family buildings, dryer vents often run long or turn sharp corners before they reach the outside. Lint builds up quickly in those runs. According to the U.S. Fire Administration, failure to clean is the leading factor contributing to clothes dryer fires in homes. Signs that a vent needs attention include clothes taking longer to dry, a hot laundry area, or a burning smell.
For air ducts, we follow the U.S. EPA's guidance. Cleaning makes sense when there is substantial visible mold growth, vermin, or excessive dust and debris. The EPA also notes that duct cleaning has not been shown to prevent health problems. It advises care with chemical treatments and with very cheap advertised offers. We will tell you honestly whether your ducts need cleaning.
