All Star Chimney Sweep's office is at 543 Henry St, right here in Cobble Hill, so homes in ZIP code 11231 are close by for us. Much of the neighborhood is brownstones, rowhouses and pre-war apartment buildings, many with masonry chimneys that have served fireplaces, boilers and water heaters for generations. Our certified technicians sweep, inspect and repair those chimneys, install liners, and clean air ducts and dryer vents. Below is what we see most often in Cobble Hill homes and how we handle it.
Older masonry chimneys in Cobble Hill homes
Brownstones and rowhouses often have several flues running up one chimney stack, one for each fireplace plus one for the boiler or water heater. Over the decades, mortar joints wear down, clay flue tiles crack, and some flues were never lined at all. Many fireplaces in these homes were closed off or made decorative long ago, and owners often don't know whether they're safe to burn in.
If a fireplace hasn't been used in years, have it checked before you light a fire. We look at the firebox, damper, smoke chamber and flue, then tell you plainly whether it's ready to use, needs repair first, or should stay decorative.
How New York weather wears on chimneys
Brooklyn winters bring repeated freeze-thaw cycles. Water that soaks into brick and mortar freezes, expands, and slowly pushes joints and brick faces apart. Nor'easters drive rain sideways into crowns and flashing, and humid summers can make a dirty flue smell strongly of creosote. Watch for these signs:
- Brick faces flaking or popping off (spalling)
- White, chalky staining on the chimney (efflorescence)
- Water stains on ceilings or walls near the chimney
- A rusted damper or firebox
- A cracked crown or a loose, missing or rusted cap
- A smoky or tar-like odor indoors during warm, damp weather
Repairs, waterproofing and rebuilding
Most water problems start at the top. A good chimney cap keeps rain, birds and squirrels out of the flue, and a sealed crown or a properly fitted chase cover stops water from running into the masonry. On sound brick, a vapor-permeable waterproofing treatment lets the chimney dry out while shedding rain.
When damage goes further, we repoint failing mortar joints, repair or replace dampers and firebox masonry, and rebuild chimneys above the roofline when the brick can't be saved. We explain what we found and why a repair is needed before any work starts.
Time for your annual chimney check?
Annual 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 called for when the system changes, such as a new appliance or a switch of fuel, or when the home is sold. A Level 3 inspection is used 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, and building owners must keep apartments heated to the city's minimum temperatures. A boiler flue problem in January is hard to fix quickly, so late summer or early fall is the best time to schedule inspections for buildings with tenants.
If your building is converting 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. We inspect the flue and install a liner sized for the new appliance.
Air duct and dryer vent cleaning
According to the U.S. Fire Administration, failure to clean is the leading factor in home clothes dryer fires. In rowhouses and apartments, dryer vents often run long distances through walls or up to the roof, where lint builds up out of sight. If clothes take longer to dry or the laundry area feels hot, the vent likely needs cleaning.
For air ducts, we follow the U.S. EPA's guidance: cleaning makes sense when there is substantial visible mold, signs of vermin, or excessive dust and debris. Duct cleaning hasn't been shown to prevent health problems, so we'll tell you honestly if your ducts don't need it, and we don't push chemical treatments.
