ClearStack Chimney Service works on chimneys, fireplaces, dryer vents and air ducts throughout Borough Park, Brooklyn (ZIP 11219). Our office in Dyker Heights is about a mile southwest of the neighborhood. Borough Park has a wide mix of housing: attached brick rowhouses, two- and multi-family homes, some detached houses, and pre-war apartment buildings alongside newer construction. Each of these vents heat and exhaust a little differently. Our certified technicians inspect the system you actually have, explain what they find in plain terms, and recommend only the work it needs.
Chimney Work for Borough Park Housing
Many Borough Park homes are attached rowhouses and multi-family buildings. Several flues often run up a shared masonry stack, and they may serve a boiler, a water heater and sometimes a fireplace. In older brick buildings, the flue tile, mortar joints and crown have had decades of heat and weather. Newer multi-family buildings may vent through metal flues or prefabricated chases.
We start by finding out what each flue serves and whether it is still in use. Then we clean, inspect and repair it in a way that suits the building's construction. If you own a detached home with a working fireplace, we check the firebox, damper and smoke chamber as well as the chimney itself.

Brooklyn Weather and Your Masonry
Brooklyn winters bring repeated freezing and thawing. Coastal storms push wind-driven rain against chimneys, and humid summers keep masonry damp. Water that soaks into brick and mortar expands when it freezes. Over time that cracks crowns, loosens joints and lets moisture into the flue and the walls around it. On attached homes, a leak at the chimney can show up as a stain on a top-floor ceiling or a shared wall.
A properly sized cap keeps rain, birds and debris out of the flue. A sound crown or chase cover sheds water away from the stack. Breathable waterproofing helps brick resist moisture without trapping it inside. When masonry is too far gone to repair, we can rebuild the damaged section of the chimney.
Oil-to-Gas Conversions and Chimney Liners
Many Brooklyn buildings have switched their boilers from oil to gas. When a New York City building makes that conversion, the chimney has to be evaluated as part of the job. A new liner is often needed because gas exhaust produces acidic condensate that can eat away at an unlined or deteriorated masonry flue. We inspect the flue, size a liner to the appliance, and install it so the exhaust vents safely.
Timing matters here. New York City's heat season runs from October 1 through May 31, and building owners must keep apartments at the city's minimum temperatures during that period. If you own a multi-family building, it is easier to schedule an inspection and any liner work before the heat season starts than to deal with a venting problem in mid-winter.

Dryer Vents and Air Ducts
According to the U.S. Fire Administration, failure to clean is the leading factor contributing to clothes dryer fires in homes. In rowhouses and apartments, dryer vents often run long distances or bend through tight spaces, and lint builds up in those runs. Cleaning the full length of the vent, not just the lint trap, keeps air moving and reduces that risk.
For air ducts, we follow the U.S. EPA's guidance. The EPA advises cleaning ducts when there is substantial visible mold growth, signs of vermin, or excessive dust and debris. It also notes that duct cleaning has not been shown to prevent health problems. We will tell you honestly whether your ducts need cleaning, and we will explain any chemical treatment before it is used.
Annual Inspections and Our Services
The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year. A Level 1 inspection fits when nothing about the system has changed. A Level 2 inspection is used when the system changes, such as a new appliance or a fuel switch, or when the home is sold. A Level 3 inspection applies when reaching a hidden hazard means opening part of the chimney or building. Services we offer in Borough Park:
