ClearStack Chimney Service works throughout Midwood, Brooklyn, in ZIP codes 11204 and 11230. Our office in Dyker Heights is about 2 miles west, so reaching a Midwood home is a short trip within the borough. Our certified technicians sweep, inspect and repair chimneys, install liners, and clean dryer vents and air ducts in detached houses, rowhouses and apartment buildings across the neighborhood. You might need a routine cleaning before winter or a closer look at a chimney that's been leaking. Either way, we explain what we find and what it means before any work starts.
Chimneys in Midwood's Older Homes
Much of Midwood's housing is older. The neighborhood has detached and semi-detached houses with their own masonry chimneys, attached rowhouses where chimneys may sit along shared walls, and pre-war apartment buildings served by boiler flues. Many of these chimneys were built for coal or oil. Since then they have gone through decades of use, patching and appliance changes.
Age shows up in predictable ways. Mortar washes out of the joints, crowns crack, old clay flue tiles separate, and dampers stop closing tightly. A careful inspection catches these problems while they are still small repairs rather than a partial rebuild.
What Brooklyn Weather Does to Masonry
New York winters bring repeated freeze-thaw cycles. Water that soaks into brick and mortar freezes, expands and pushes the masonry apart a little more each time. Wind-driven rain from coastal storms in spring and fall adds to the problem, and so do humid summers. A chimney with no cap or a cracked crown can take in a surprising amount of water over a year.
That moisture leads to flaking brick, rusted dampers, stained walls and ceilings near the chimney, and musty fireplace odors. These services help keep water out:
- Chimney caps and chase covers to keep rain, snow, animals and debris out of the flue
- Chimney repair, including crown repair, repointing and flashing work where the chimney meets the roof
- Chimney waterproofing with a water repellent that lets masonry release trapped vapor
- Chimney rebuilding when freeze-thaw damage has gone too far for repair
Inspections, Heat Season and Oil-to-Gas Conversions
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, for example a new appliance or a fuel switch, or when the home is sold. A Level 3 inspection is needed when a hidden hazard can only be reached by opening part of the chimney or building.
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 you own a multi-family building in Midwood, have the boiler chimney checked before October so a problem doesn't sideline your heat in the middle of winter.
Many Brooklyn buildings have converted from oil to gas. When a New York City building makes that switch, 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. We evaluate the flue and install the liner when one is needed.

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 many older houses the dryer sits in the basement and vents through a long run with several turns, and that kind of run collects lint faster. Signs that a vent needs attention include clothes taking longer to dry, a hot laundry room, and a burning smell.
For air ducts, we follow the U.S. EPA's guidance. The EPA advises cleaning when there is substantial visible mold growth, vermin, or excessive dust and debris. It also says duct cleaning has not been shown to prevent health problems. We'll tell you plainly whether your ducts need cleaning, and we're careful about chemical treatments.
