EverSafe Chimney Sweep cleans, inspects and repairs chimneys, fireplaces, dryer vents and air ducts throughout Park Slope, Brooklyn, in the 11217 ZIP code. Our office is in Fort Greene, about a mile to the northeast, so Park Slope is one of the closest neighborhoods we serve. Our certified technicians work on all kinds of homes here, from brownstones with fireplaces on several floors to rowhouses with old flues that haven't been looked at in decades to pre-war apartment buildings with boiler chimneys. They explain what they find in plain terms.

Chimneys in Park Slope's Brownstones and Rowhouses

Much of Park Slope's housing is older masonry, including brownstones, brick rowhouses and pre-war apartment buildings. Many of these homes have more than one flue running up a shared chimney stack. They may also have fireplaces on the parlor and upper floors that haven't been used in years. Some were built for coal and later closed off. Others were relined at some point, and many have never been fully documented.

Before anyone lights a fire in a fireplace that has sat unused, we recommend a sweep and inspection. We check for blockages such as old nests and fallen debris. We also look for cracked or missing flue tiles, a damper that no longer seals, and gaps where heat could reach wood framing. If the flue isn't safe to use, we walk you through the options, which range from fireplace and damper repair to a new liner or rebuilding damaged masonry.

How Brooklyn Weather Wears on Masonry Chimneys

Brooklyn winters swing above and below freezing many times in a season. Water soaks into brick, mortar or a cracked crown, then freezes and expands, which widens the cracks. Over time, mortar joints wash out and brick faces flake away. Wind-driven rain from coastal storms pushes water into the top of an uncapped flue. Humid summers can also bring out a smoky smell from damp creosote inside the chimney.

Most of that damage starts at the top of the chimney, so that is where we focus prevention:

  • Chimney caps to keep out rain, animals and debris
  • Chase covers for framed chimneys and prefabricated fireplaces
  • Crown and mortar repair before small cracks turn into loose bricks
  • Breathable chimney waterproofing that lets masonry dry out instead of trapping moisture
  • Rebuilding the upper courses when brickwork above the roofline has deteriorated

Yearly Inspections and What Each Level Means

The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year. There are three inspection levels, and the right one depends on what has changed:

If you are buying or selling a Park Slope brownstone, a Level 2 inspection gives both sides a clear picture of the chimney before closing.

  • Level 1 is a routine check used when nothing about the system has changed.
  • Level 2 is needed when the system changes, such as a new appliance or a switch of fuel, or when the home is sold.
  • Level 3 is used when a hidden hazard can only be reached by opening part of the chimney or building.

Boiler Chimneys, Oil-to-Gas Conversions and Heat Season

Many Park Slope rowhouses and apartment buildings vent a boiler through a masonry chimney. When a New York City building converts 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 an old masonry flue. We inspect the flue and install a properly sized liner when one is called for.

Timing matters too. New York City's heat season runs from October 1 through May 31. During that period, building owners must keep apartments heated to the city's minimum temperatures. Scheduling chimney inspection and liner work in late spring or summer helps keep the heating system ready before fall.

Dryer Vent and Air Duct Cleaning

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 through tight walls before they reach the outside, which lets lint build up. We clean the full vent run, clear the exterior hood, and check for crushed or disconnected sections.

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. Duct cleaning has not been shown to prevent health problems, so we won't promise that it will. We explain our process before we start, and we use chemical treatments only when there's a clear reason and you agree to it.

Serving Park Slope and Nearby Neighborhoods

Park Slope is close to our Fort Greene office, so we work here regularly. We also serve the nearby neighborhoods of Prospect Heights, Carroll Gardens, Cobble Hill and Gowanus, as well as Fort Greene itself. Homes across these neighborhoods share much of the same older masonry, so the same careful approach applies whether your chimney tops a brownstone or a pre-war apartment building.

FAQ

Common questions

How often should my Park Slope chimney be inspected?

The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year. For most homes where nothing has changed, a Level 1 inspection is enough. A Level 2 inspection is needed when you add a new appliance, switch fuels or sell the home.

Is it safe to use a brownstone fireplace that hasn't been used in years?

Don't use it until it has been swept and inspected. Unused flues often have debris, nests, cracked tiles or a damper that doesn't seal. We'll tell you whether it's ready to use or what repairs it needs first.

Our building is converting from oil to gas. Do we need a new chimney liner?

The chimney has to be evaluated as part of any oil-to-gas conversion in New York City, and a new liner is often needed. Gas exhaust produces acidic condensate that can corrode a masonry flue, so we inspect the flue and recommend a liner when the existing one isn't suitable.

Why does my chimney smell in the summer?

Humid Brooklyn summers and rain entering the flue can dampen creosote deposits, which gives off a smoky odor. A sweep removes the deposits. A chimney cap and waterproofing help keep moisture out.

Do you serve neighborhoods near Park Slope?

Yes. Along with Park Slope, we regularly serve Prospect Heights, Carroll Gardens, Cobble Hill, Gowanus and Fort Greene, where our office is located.

Will air duct cleaning improve my family's health?

The U.S. EPA says duct cleaning has not been shown to prevent health problems. It recommends cleaning when there is substantial visible mold growth, vermin, or excessive dust and debris, and those are the situations where we recommend it.
