The short answer
EmberGuard Chimney Sweep serves Flatiron, Manhattan with chimney sweeping, inspections, repairs, liner installation, waterproofing, and dryer vent and air duct cleaning. The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year, and late summer or early fall, before the city's October 1 heat season start, is a practical time to schedule.
EmberGuard Chimney Sweep cleans, inspects and repairs chimneys, fireplaces, dryer vents and air ducts in Flatiron, including ZIP code 10119. Our office is about 2 miles southwest of the neighborhood, so Flatiron is a short trip for our crews. Most homes here are in pre-war apartment buildings, converted loft buildings and the occasional rowhouse, and each has its own chimney and venting setup. Our certified technicians handle everything from a wood-burning fireplace in a single unit to a shared flue serving a building's boiler.
Chimney Work in Flatiron's Older Buildings
Much of Flatiron's housing is in pre-war apartment buildings and lofts converted from commercial use. Many of these buildings have masonry chimneys that have served several generations of heating equipment, and some apartments still have working fireplaces. Over decades, mortar wears, flue tiles crack, and dampers rust or stop sealing.
We start with an inspection so you know the condition of the chimney before any work begins. Chimney professionals use three inspection levels. 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 switch of fuel, or when the home is sold. A Level 3 inspection is reserved for hidden hazards that can only be reached by opening part of the chimney or building.

Weather, Masonry and Timing
New York winters bring repeated freezing and thawing. Water that soaks into brick and mortar expands when it freezes, which loosens joints and chips masonry over time. Wind-driven rain from coastal storms can push water into gaps around the crown and flashing, and humid summers can leave older flues damp and smelling of soot.
A chimney cap and a properly fitted chase cover keep rain, debris and animals out of the flue. Waterproofing treatments for masonry slow down water absorption. When damage has gone too far for repair, we rebuild the affected section of the chimney.
Timing matters in the city. New York City's heat season runs from October 1 through May 31, when building owners must keep apartments heated to the city's minimum temperatures. Scheduling inspections and repairs before October means a building's heating system and chimney are ready when the heat has to be on.
Oil-to-Gas Conversions and Chimney Liners
Some Flatiron buildings have converted, or are planning to convert, their boilers from oil to gas. When a New York City building makes this 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 inspect the existing flue, explain what we find, and install a liner sized for the new equipment when one is needed. A switch of fuel is also one of the situations that calls for a Level 2 inspection.

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 apartments and lofts, dryer vents often run a long way to reach an exterior wall, and lint builds up along the way. We clean the full vent run, not just the area behind the dryer.
For air ducts, we follow the U.S. EPA's guidance. The EPA advises cleaning ducts 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, and it advises care with chemical treatments. We will tell you plainly whether your ducts need cleaning.
