The short answer
All Star Chimney Sweep serves Prospect Heights with chimney sweeping, inspections, repairs, liner installation, waterproofing, and dryer vent and air duct cleaning. We focus on the problems common in older brownstones, rowhouses and pre-war buildings, including freeze-thaw damage and boilers converted from oil to gas.
Prospect Heights is a compact Brooklyn neighborhood of brownstones, rowhouses and pre-war apartment buildings, about 2 miles east of our Brooklyn office. Many of these buildings have masonry chimneys that have served several generations of owners, along with dryer vents and duct systems added over the years. All Star Chimney Sweep cleans, inspects and repairs chimneys, fireplaces and vents throughout the neighborhood. Our certified technicians are used to attached homes, where roof access, shared walls and tight interiors call for careful planning.
Older Masonry, Newer Appliances
Many Prospect Heights homes were built when coal and wood heat were common. Their chimneys were not designed for today's gas boilers, water heaters or high-efficiency appliances. Over the decades, owners have changed fuels, sealed off fireplaces, reopened them or added new flues, and each change affects how the chimney draws and how its interior holds up.
When a building converts its boiler from oil to gas, the chimney has to be evaluated as part of that work. A new liner is often needed because gas exhaust produces acidic condensate that can corrode a masonry flue from the inside. We inspect the flue, explain what we find in plain terms and install a properly sized liner when one is required.

How Brooklyn Weather Wears on Chimneys
Brooklyn winters bring repeated freeze-thaw cycles. Water that soaks into brick and mortar expands when it freezes. Over time, that loosens joints, cracks crowns and breaks the faces off bricks. Wind-driven rain from coastal storms finds any gap in flashing or a cracked crown, and humid summers can pull moisture and odors down an unused flue.
New York City's heat season runs from October 1 through May 31, so boilers and furnaces work hard for most of the year. Late summer and early fall are practical times to schedule cleaning and repairs, before the heating system is running every day. Signs that your chimney needs attention include:
- Cracked or crumbling chimney crowns
- Missing or rusted caps that let in rain, birds and debris
- Loose mortar joints or bricks with flaking faces
- Water stains on ceilings or walls near the chimney
- Damp, smoky or musty odors from the fireplace

Annual Inspections and When to Look Deeper
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 called for when the system changes, such as a new appliance or a switch of fuel, and when a home is sold. A Level 3 inspection is used when a suspected hazard is hidden and part of the chimney or building has to be opened to reach it.
In a brownstone or rowhouse that has gone through renovations, we often recommend a Level 2 inspection so we can check the full length of the flue with a camera. If you are buying or selling in Prospect Heights, that inspection gives both sides a clear picture of the chimney's condition.
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 through walls or ceilings before reaching the outside. That leaves more places for lint to build up. If drying times are getting longer or the laundry area feels unusually hot, it is time for a cleaning.
For air ducts, we follow EPA guidance. The EPA advises cleaning ducts when there is substantial visible mold growth, vermin, or excessive dust and debris. It also notes that duct cleaning has not been shown to prevent health problems, and it urges caution with chemical treatments. We'll tell you honestly whether your ducts need cleaning, and we'll explain any treatment before using it.
Nearby Neighborhoods We Serve
Along with Prospect Heights, we work throughout the surrounding parts of Brooklyn, including Park Slope, Fort Greene, Downtown Brooklyn, DUMBO and Boerum Hill. Many homes in these areas share the same mix of older masonry and updated heating systems, so the same careful approach applies.
