If you've been told you need a chimney inspection, you may have heard the terms Level 1, Level 2 or Level 3. These are the three inspection levels chimney professionals use to match the depth of the inspection to your situation. The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year. This guide explains what each level covers, when each one makes sense, what you get afterward, and how to get your home ready. Our certified technicians at AshVanta Chimney Services follow this framework on every inspection we perform in New York.
Level 1: The Annual Inspection
A Level 1 inspection is the standard yearly check for a chimney that is being used the same way it was last year. Nothing about the appliance, the fuel or the venting has changed, and you aren't aware of any problems.
The technician looks at the parts of the chimney and fireplace that can be reached without special tools or opening anything up. The goal is to confirm the system is structurally sound, free of blockages and safe to keep using.
For many homes, a Level 1 inspection is paired with a chimney sweep, since built-up creosote and debris are among the most common findings.
- Readily accessible parts of the chimney exterior and interior
- The fireplace or appliance connection and the damper
- Signs of creosote buildup, obstructions or animal nests
- Visible cracks, gaps or damage to the firebox and flue
Level 2: When Something Changes
A Level 2 inspection goes further than Level 1. It includes everything in a Level 1 inspection, plus a video scan of the inside of the flue and a look at accessible areas such as the attic, crawl space and basement where the chimney passes through.
Level 2 is called for when the system changes or the home is sold. In New York City, one common trigger is a boiler conversion from oil to gas. When a building makes that switch, 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. If a liner is needed, our chimney liner installation service can handle it.
We also recommend a Level 2 inspection after a chimney fire or a severe storm, since damage inside the flue is often invisible from the fireplace or the roof.
- Installing a new stove, insert, furnace or boiler
- Switching fuel, such as oil to gas or wood to gas
- Changing the shape, material or size of the flue, such as relining
- Buying or selling a home
- After a chimney fire, a severe storm or any event that may have damaged the chimney
Level 3: Reaching Hidden Hazards
A Level 3 inspection is the most involved. It is used when a serious hazard is suspected and the only way to confirm it is to open part of the chimney or building, such as removing a section of the chimney crown, chase or interior wall.
This level is not routine. It usually follows a Level 1 or Level 2 inspection that turned up signs of a concealed problem. Because it involves removing materials, we explain why it is needed and what will be opened before any work begins. Findings from a Level 3 inspection often lead to chimney repair or chimney rebuilding.
What You Get After Your Inspection
Every inspection ends with clear documentation, so you know exactly what was found and why it matters. You don't have to take our word for it; you can see the conditions yourself.
If we recommend repairs, such as a new chimney cap and chase cover, chimney waterproofing, or fireplace and damper repair, the report explains the reason and what happens if the issue is left alone.
- Photos of key areas and any problems found
- Video footage of the flue interior for Level 2 and Level 3 inspections
- A written report describing conditions, concerns and recommended next steps
- A plain-language walkthrough with the technician before we leave
How to Prepare for Your Inspection Visit
A little preparation helps the visit go smoothly and lets the technician see everything that needs to be checked. Plan ahead if you rely on your fireplace or a fuel-burning appliance during New York City's heat season, which runs from October 1 through May 31; scheduling before or early in that season avoids surprises when you need heat most.
- Don't use the fireplace or stove the day before the visit so it's cold when we arrive
- Clear a few feet of space around the fireplace, stove or appliance
- Move fragile items off the mantel and nearby shelves
- Make sure we can reach the attic, basement or crawl space for a Level 2 inspection
- Secure pets in another room
- Have notes ready about recent changes, odors, smoke problems or leaks
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.
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 them.
Which inspection level do I need?
If nothing has changed, a Level 1 inspection is usually enough. If you've changed your appliance or fuel, are buying or selling a home, or had a chimney fire or storm damage, a Level 2 is appropriate. Level 3 is only used when a hidden hazard has to be reached by opening part of the chimney or building.
Do I need a Level 2 inspection if my building is switching from oil to gas?
Yes. When a New York City building converts its boiler from oil to gas, the chimney has to be evaluated, and a new liner is often needed because gas exhaust produces acidic condensate that can corrode a masonry flue.
Will a Level 3 inspection damage my home?
A Level 3 inspection does involve removing some materials to reach the problem area. We explain what will be opened and why before starting, so there are no surprises.
Is an inspection the same as a chimney sweep?
No. An inspection evaluates the condition and safety of the chimney, while a sweep removes creosote, soot and debris. Many homeowners schedule both in the same visit.
What will I receive after the inspection?
You'll receive photos, video of the flue for Level 2 and Level 3 inspections, and a written report describing what we found and any recommended next steps.
