Nexora Chimney Services sweeps fireplaces and boiler flues from our office at 304 E 20th St in Peter Cooper Village. The NFPA 211 standard calls for chimneys to be inspected once a year. Late summer or early fall, before heat season starts on October 1, is a good time to book.
Nexora Chimney Services is based at 304 E 20th St in Peter Cooper Village, so when someone in the neighborhood needs a chimney sweep, we're coming from just down the street. Homes here and in the surrounding parts of Manhattan range from large apartment buildings to pre-war walk-ups, rowhouses and brownstones, and each type puts different demands on a chimney. Some homes have a wood-burning fireplace that gets used every winter weekend. Others have a flue that only serves a boiler and rarely gets attention until something goes wrong. Our certified technicians sweep both, and we explain what we find in plain terms so you can decide what, if anything, needs to happen next.
What a Chimney Sweep Covers
A sweep removes the soot and creosote that build up inside a flue when wood, oil or gas is burned. Creosote is flammable, and a thick layer of it can turn an ordinary fire into a chimney fire. Sweeping also clears obstructions such as nesting material, leaves and debris. These blockages can stop exhaust from escaping and push smoke or carbon monoxide back into the room.
- Covering floors and furniture near the fireplace or appliance and sealing off the opening
- Brushing the flue, smoke chamber and smoke shelf, then vacuuming up the debris so it stays out of your home
- Checking that the damper opens, closes and seals properly
- Looking at the firebox, liner and visible masonry for cracks, gaps or deterioration
- Noting the condition of the chimney cap and crown when roof access is available
- Walking you through what we saw, with photos when they help

Chimneys in Peter Cooper Village and Nearby Homes
In apartment buildings, chimneys and boiler flues are usually shared systems managed by the building. If your apartment has a working fireplace, check with management before booking. Some buildings schedule sweeps for the whole stack, and roof access often has to be arranged in advance. We're used to coordinating with supers and managing agents on timing, elevator use and access.
Rowhouses and brownstones in nearby neighborhoods such as Gramercy and the East Village often have older masonry flues, sometimes several in one building. Not all of them were built for the appliance now connected to them. Older fireplaces may have no liner at all, or a clay liner with cracked or missing sections, and a sweep is often when those problems turn up.
Boiler flues need attention too. 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 a masonry flue. Sweeping and inspecting the flue is a sensible first step in that process.
When to Book a Chimney Sweep
The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year. Sweeping is done when the inspection shows it's needed, which for most households that burn wood regularly means about once a year. Late summer and early fall work well here. New York City's heat season runs from October 1 through May 31, and boilers and fireplaces see their heaviest use during those months.
Don't wait for your regular appointment if you notice any of these signs:
- A strong smoky or campfire smell from the fireplace, especially in humid weather
- Smoke drifting into the room instead of rising up the flue
- Black flakes or crumbly deposits falling into the firebox
- Animal sounds or nesting debris in the chimney
- A fireplace you're about to use for the first time since moving in

Sweeping and Inspection Levels
Sweeping and inspection go together, and chimney professionals use three inspection levels. 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, or when the home is sold. That makes it useful if you're buying or selling a co-op or townhouse in the area. A Level 3 inspection is reserved for cases where a hidden hazard has to be reached by opening part of the chimney or building.
Most routine sweeps come with a Level 1 inspection. If we see something that needs a closer look, we'll explain why and what the next level would involve before doing anything more.
