The short answer
A chimney inspection is a structured check of your fireplace, flue, and chimney exterior to confirm it can safely carry smoke and exhaust out of your home. The NFPA 211 standard calls for an inspection once a year, and the level of inspection depends on whether anything has changed. Schedule one yearly, after any change to your heating system, and before buying or selling a home.
A chimney inspection tells you whether your fireplace, wood stove, or boiler flue is safe to use and what, if anything, needs attention before the next fire or the next heating season. EverSafe Chimney Sweep's certified technicians inspect chimneys in Brooklyn homes and nearby communities, from row house and brownstone fireplaces to the flues that vent oil and gas boilers. We check the system from the firebox to the crown, explain what we find in plain terms, and leave you with written findings and photos you can keep for your records, a planned repair, or a home sale.
Signs you need a chimney inspection
Most chimney problems develop slowly and out of sight, so the early clues tend to show up inside the house. If you notice any of the following, it is worth having the chimney looked at before you light another fire or start the boiler for the season.
- A smoky or creosote smell, especially on humid days or when the air conditioning is running
- Poor draft: smoke rolling into the room, fires that are hard to start, or a fire that dies down quickly
- Debris, loose mortar, or flakes of brick or tile collecting in the firebox
- White, powdery staining on the brick inside or outside, which usually points to moisture moving through the masonry
- Scratching, chirping, or fluttering sounds from inside the chimney
- Water, rust, or damp stains in the firebox or on the damper after rain
What a chimney inspection includes
Every inspection follows the same checklist so nothing is skipped. If we find something that needs a closer look, we explain why before going further.
- Firebox, smoke chamber, and damper condition and operation
- Flue liner: cracks, gaps, missing mortar, or deterioration along its length
- Creosote and soot buildup, and whether a sweep is needed
- Obstructions such as nests, animals, leaves, or fallen debris
- Clearances from wood framing and other combustible materials, where accessible
- Connection between the flue and any stove, insert, or boiler
- Chimney exterior: brick, mortar joints, crown, cap, and flashing where the chimney meets the roof
- Signs of water entry and moisture damage
- Written findings with photos and clear recommendations
How our crew works in your home and on the roof
Inside, we lay drop cloths from the door to the fireplace and cover the hearth before opening anything. We run HEPA vacuums while we work so soot and dust stay in the chimney and out of the room. If the flue needs to be cleared before it can be properly seen, we use rotary brushes sized to the liner and vacuum as we go.
For the flue itself, we use a chimney camera wherever it fits, which lets us see cracks, gaps, and buildup along the full height of the liner instead of only the first few feet. You are welcome to watch the footage with us.
On the roof, we check the crown, cap, flashing, and masonry, and look down the flue from the top. Many Brooklyn homes have flat roofs reached through a hatch or bulkhead, while others have steeper pitches that call for ladders and extra safety setup. We confirm access with you before the visit so we arrive with the right equipment.
The standard we follow: NFPA 211 and the three inspection levels
The NFPA 211 standard calls for chimneys, fireplaces, and vents to be inspected once a year. Chimney professionals use three inspection levels to match the depth of the inspection to the situation.
A Level 1 inspection covers the readily accessible parts of the chimney and is used when nothing about the system has changed. A Level 2 inspection is used when the system changes, such as a new stove or insert, a switch of fuel, or when the home is being sold; it adds a camera inspection of the flue and a look at accessible areas like attics and crawl spaces. A Level 3 inspection is only needed when a hidden hazard has to be reached by opening part of the chimney or building, and we will always discuss it with you first.
If you are converting a boiler from oil to gas, New York City requires the chimney 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. Since the city's heat season runs from October 1 through May 31, scheduling your inspection in late summer or early fall leaves time for any repairs before you need heat.
What affects the cost of a chimney inspection
We quote each job after learning about your chimney, since no two are quite the same. The main factors are:
- Chimney height and how we reach the roof, whether through a hatch or with ladders on a pitched roof
- Fuel type: wood, gas, or oil, and whether the flue serves a fireplace, stove, or boiler
- Flue size, shape, and condition, including whether there is a liner at all
- How much creosote, soot, or debris has built up
- Whether a camera inspection, a Level 2 or Level 3 inspection, or follow-up repair is needed
How a visit works
When you reach out, we ask a few questions about your home, the fuel you burn, roof access, and any problems you have noticed. That helps us plan the right inspection level and equipment. We ask that you not use the fireplace or stove for at least a day beforehand so the chimney is cool.
On the day of the visit, we protect your floors, inspect the firebox and flue from inside, then move to the roof. Most inspections are finished in one visit. Before we leave, we walk you through what we found, show you the photos or camera footage, and send written findings. If anything needs cleaning or repair, we explain the options and let you decide on your own schedule, with no pressure.
