A chimney inspection is not one-size-fits-all. Chimney professionals use three inspection levels, and each one goes a step deeper than the last. The right level depends on your situation: whether anything about your system has changed, whether you're buying or selling, or whether a technician suspects a problem that can't be seen from the outside. This guide explains what each level covers, when you need it, what you'll receive afterward, and how to get your home ready for the visit.
Why Chimneys Need a Yearly Inspection
The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year. That applies whether you burn wood in an open fireplace, run a gas insert, or have a boiler or furnace venting through a masonry chimney. Creosote, soot, debris, animal nests, cracked flue tiles and moisture damage can all build up quietly between seasons.
In Brooklyn, many homes rely on a chimney to vent the heating system through the coldest months. 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 your inspection before that stretch begins gives you time to handle any repairs before the system is working hardest.
Level 1: The Routine Annual Inspection
A Level 1 inspection is the standard yearly check for a chimney that is in regular use and hasn't changed since its last inspection. It's the right choice when you're using the same appliance, the same fuel and the same setup as before.
During a Level 1 inspection, the technician examines the readily accessible parts of the chimney, fireplace and connections. No special tools are needed to open doors, panels or coverings, and nothing is removed from the structure.
- Accessible portions of the chimney exterior and interior
- The firebox, damper and smoke chamber as far as they can be seen
- Appliance connections and the flue for blockages and buildup
- Signs of creosote, soot accumulation or obvious damage
- Basic clearance from combustible materials where visible
Level 2: When Something Changes
A Level 2 inspection covers everything in Level 1 and adds a closer look at accessible areas such as attics, crawl spaces and basements, along with a video scan of the inside of the flue. The camera lets the technician see cracks, gaps and deterioration along the full length of the liner that can't be spotted from the top or bottom.
Under the NFPA 211 framework, a Level 2 inspection is called for when the system changes or the home is sold. That includes installing a new appliance, relining the chimney, or switching fuels. We also recommend a Level 2 inspection after a chimney fire, a strong storm, an earthquake or any event that may have damaged the chimney.
Fuel switches deserve special attention 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, and a new liner is often needed because gas exhaust produces acidic condensate that can corrode a masonry flue.
- Buying or selling a home
- Converting from oil to gas, or wood to gas
- Installing a new stove, insert, boiler or furnace
- After a chimney fire or storm damage
- Changing the shape, size or material of the flue
Level 3: Reaching Hidden Hazards
A Level 3 inspection is needed when a serious hazard is suspected and can only be reached by opening part of the chimney or building. This may mean removing a section of interior wall, a chimney crown or masonry to see what's behind it.
Level 3 inspections are not routine. They're typically recommended when a Level 1 or Level 2 inspection uncovers a sign of a deeper problem, such as evidence of heat damage to nearby framing or a concealed defect that affects safety. Your technician will explain what needs to be opened and why before any work begins.
What You Receive After Your Inspection
Our certified technicians document what they find so you're not left guessing. After your inspection, you'll receive a written report describing the condition of your chimney, fireplace or vent, along with any issues found and recommended next steps.
Photos are included to show problem areas, and Level 2 inspections include video footage from inside the flue. This documentation is useful for planning repairs, sharing with a buyer or seller during a home sale, or keeping on file for your next yearly check. If repairs are needed, such as liner installation, crown work or damper repair, we'll walk you through the options.
How to Prepare for Your Inspection
A little preparation helps the visit go smoothly and lets the technician see everything they need to.
- Stop using the fireplace or stove the day before so the firebox and flue are cool
- Clear a path to the fireplace and move furniture, rugs and decor a few feet away
- Make sure the technician can reach the attic, basement or boiler room if needed
- Secure pets in a separate room during the visit
- Note any smells, smoke, drafts, leaks or noises you've noticed and share them
- Have any past inspection reports or appliance details handy
Inspections
Three levels of chimney inspection
The NFPA 211 standard calls for a yearly inspection. Which level you need depends on what has changed since the last one.
-
Level 1
Annual check
For a chimney and appliance that have not changed and will be used the same way: the readily accessible parts of the chimney, the flue and the connection, checked for soundness, blockages and deposits.
-
Level 2
Camera inspection
When something changed — a new stove, insert or boiler, a fuel switch such as oil to gas, the sale of the home, or a chimney fire, storm or quake. Adds a video scan of the whole flue and the accessible attic, roof and crawl spaces.
-
Level 3
Concealed areas
Only when a Level 1 or 2 points to a hidden hazard that cannot be checked any other way: parts of the chimney or building are opened to reach it.
FAQ
Common questions
How often should my chimney be inspected?
The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year, even if you rarely use your fireplace.
Which inspection level do I need?
Most homes need a Level 1 inspection each year. If you've changed fuel or appliances, are buying or selling a home, or had a chimney fire or storm damage, a Level 2 is the right choice. Level 3 is only for suspected hidden hazards.
Do I need a Level 2 inspection when converting from oil to gas?
Yes. A fuel switch is a change to the system. In New York City, the chimney must be evaluated during an oil-to-gas boiler conversion, and a new liner is often needed because gas exhaust creates acidic condensate that can corrode a masonry flue.
Is an inspection the same as a chimney sweep?
No. A sweep removes creosote, soot and debris, while an inspection evaluates the condition and safety of the system. Many homeowners schedule both at the same visit.
Will a Level 3 inspection damage my home?
A Level 3 inspection does involve opening part of the chimney or building to reach a hidden hazard. Your technician will explain exactly what needs to be opened and why before any work starts.
Do I get documentation after the inspection?
Yes. You'll receive a written report with photos, and Level 2 inspections include video from inside the flue.
