The short answer
A chimney sweep removes creosote, soot and blockages from your flue and includes a basic visual inspection of the chimney system. The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year, so most homeowners should schedule a sweep and inspection annually, ideally before the heating season starts.
A chimney collects soot, creosote and debris every season it is used. Brooklyn's mix of older masonry chimneys, converted boilers and wood-burning fireplaces gives that buildup plenty of places to hide. A chimney sweep removes those deposits so smoke and exhaust leave your home the way they should. It also gives our certified technicians a close look at the flue, firebox, smoke chamber, damper and cap. Expert Chimney Sweep cleans fireplace and heating appliance chimneys for homeowners in Brooklyn and nearby cities. We work carefully inside your home and explain clearly what we find.
Signs You Need a Chimney Sweep
Most homeowners call us after noticing something small that doesn't seem right. These are the common signs that a chimney is due for cleaning or a closer look:
If it has been more than a year since your last cleaning or inspection, schedule one even if nothing seems wrong. Many problems inside a flue can't be seen or smelled from the living room.
- A smoky, tar-like or campfire smell, especially on humid days or when the air conditioning runs. This often points to creosote in the flue.
- Poor draft, such as smoke rolling into the room, fires that are hard to start, or fires that die down quickly
- Soot clumps, debris or flakes of brick and mortar landing in the firebox
- White staining on the outside brick, which shows that water is moving through the masonry
- Scratching, chirping or rustling inside the chimney, which usually means birds or animals have moved in
- Water dripping or pooling in the firebox after rain

What's Included in a Chimney Sweep
Every chimney sweep visit covers the following:
- Drop cloths and a HEPA vacuum set up at the fireplace or appliance opening before any brushing starts
- Brushing the full length of the flue with rotary or manual brushes sized to the flue
- Cleaning the firebox, smoke shelf and smoke chamber
- Checking the damper and confirming it opens, closes and seals
- Removing loose soot, nesting material and blockages that can be safely reached
- A Level 1 visual inspection of the accessible parts of the chimney, from the firebox to the cap
- A look at the cap, crown and flashing from the roof when access is safe
- A plain-language explanation of what we found, with photos when they help
- Written recommendations for any repairs or further inspection
How Our Crew Works Inside Your Home and on the Roof
Inside, we protect the room before we touch the chimney. Drop cloths go down from the fireplace or appliance to the door we use, and a HEPA vacuum runs at the opening during brushing. The vacuum draws dust and soot into the machine instead of into your living space. We work through the opening with rotary brushes that spin against the flue walls to loosen creosote and soot, and we switch to manual brushes where the flue shape calls for it.
When we can't see the condition of the flue from the bottom or the top, or a problem is suspected, we may recommend a camera inspection. The camera runs up the flue and shows cracked tiles, gaps in mortar joints, damaged liners and blockages that a flashlight can't reach. We share the footage with you so you can see what we see.
On the roof, we check the chimney cap, crown, flashing and outside brick, and we brush from the top when that is the better approach. Many Brooklyn homes have flat roofs reached through a hatch or bulkhead. We only go up when the roof can be accessed safely, and we tell you beforehand if access will be a problem.
Time for your annual chimney check?
The Standard We Follow
The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year. 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 to a different fuel, or when the home is being sold. A Level 3 inspection is needed when a hidden hazard can only be reached by opening part of the chimney or building.
Fuel changes matter in New York City. When a 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. If you are planning a conversion, tell us when you book so we can plan for the right level of inspection.
Timing matters too. New York City's heat season runs from October 1 through May 31. Scheduling your sweep in late summer or early fall gives you time to handle any repairs before the boiler or fireplace is in steady use.
What Affects the Price
Every chimney is different, so we quote after we know what we're working with. These factors have the biggest effect:
- Chimney height and how easy the roof is to reach
- Fuel type: wood, oil or gas
- Flue size, shape and current condition
- How much creosote, soot or debris has built up
- Whether a camera inspection is needed
- Whether repairs such as a cap, damper or liner work are recommended
How a Visit Works
When you book, we'll ask what the chimney serves, what fuel it burns and whether you have noticed any of the warning signs above. For a fireplace, please let the fire burn out and leave the ashes to cool for at least a day before we arrive.
On the day of the visit, the technician walks through the job with you, sets up drop cloths and the HEPA vacuum, cleans the chimney and inspects it. Before leaving, they clean up the work area, review the findings with you, and explain any recommended repairs or further inspection. Nothing beyond the sweep is done without your approval.
