What Are the Levels of Chimney Inspection? Level 1, 2 and 3 Explained

By Garrett Sullivan, 16 years of experience · November 13, 2026 · 7 min read

What are the levels of chimney inspection? Level 1 checks accessible areas visually, Level 2 adds a video scan and broader access, and Level 3 may require opening concealed areas. The right level depends on the chimney’s condition and what has changed.

What Are the Levels of Chimney Inspection and When Do They Apply?

The levels describe how far an inspection goes, not three grades of chimney quality. A Level 1 inspection looks at readily accessible parts of the chimney and appliance. Level 2 adds checks of accessible areas such as attics or crawlspaces and a video scan of the flue. Level 3 is the most intrusive option, used when a serious hazard is suspected and hidden parts need to be exposed.

For a chimney that has stayed in the same service and shows no known problems, Level 1 may fit. Changes to the appliance or fuel, a home sale, relining, or a fire or severe weather event can call for Level 2. Level 3 may be appropriate when findings point to a hazard that cannot be assessed through normal access. The CSIA Level 2 inspection procedure describes these common reasons for a closer inspection.

How Level 1, Level 2 and Level 3 Inspections Differ

An inspection level is selected for the circumstances and the access needed to assess the system. It is not a menu where choosing the most extensive option automatically means the chimney is safer.

Which Chimney Inspection Level Fits Your Situation?

Use the history of the chimney and the reason for the inspection to guide the conversation. Tell the chimney sweep what changed, what you noticed, and whether the fireplace or appliance has been used since the concern appeared.

• No known change or problem — A Level 1 inspection may be suitable when the appliance, fuel and chimney use remain the same, and there is no known damage or concerning symptom.
• Buying or selling a home — Ask about a Level 2 inspection. A visual check alone may not cover concealed or less accessible portions of the system.
• Changing an appliance, fuel or liner — A Level 2 inspection is commonly recommended when the system’s setup changes or before relining, so the flue and accessible surrounding areas can be evaluated.
• After a fire or weather event — Request an assessment before using the fireplace again. Level 2 is commonly recommended after these events; visible or suspected hidden damage may affect the needed scope.
• A serious problem may be concealed — A chimney professional may recommend Level 3 if the concern cannot be examined through regular access. This level can involve opening concealed sections, so ask what area needs access and why.

What Happens During a Chimney Inspection, Step by Step

The exact scope depends on the selected level and the chimney’s access. These steps describe the kinds of checks an inspection may include; a Level 1 visit does not include every Level 2 or Level 3 procedure.

1. Describe the system and its history — Tell the sweep what appliance and fuel you use, whether anything changed, and what prompted the inspection. Check that you have mentioned any fire, weather event, smoke problem or recent alteration.
2. Look over the firebox and appliance — The inspector checks accessible parts of the firebox and appliance for visible concerns. Note any cracks, loose parts or unusual residue you have seen, and point out where they appear.
3. Examine the damper and smoke passage — The damper and accessible smoke chamber are among the areas that may be checked. The inspector looks for visible damage or obstruction; a damper that does not move or close properly is important to mention.
4. Check accessible chimney surfaces — Accessible masonry, metal components and connections can be examined for visible wear or damage. The inspector records what is in view and whether the inspection level requires access beyond it.
5. Inspect accessible surrounding spaces when needed — For Level 2, the inspector may check accessible areas such as an attic, crawlspace or basement around the chimney. The check looks for visible conditions that cannot be seen from the fireplace opening.
6. Scan the flue for Level 2 — A video camera is used to examine the flue interior during a Level 2 inspection. The scan helps reveal conditions inside the passage that a view from the firebox or chimney top may miss.
7. Consider Level 3 access only when indicated — If the concern remains hidden and a serious hazard is suspected, the inspector may recommend opening a concealed area. Ask which part needs to be exposed and what finding made that access necessary.
8. Review the findings and next action — Ask which areas were inspected, what the findings mean, and whether cleaning, repair or further access is recommended. Ohio Chimney and Fireplace explains the work clearly and recommends only services a homeowner needs.

When Chimney Symptoms Call for More Than a Visual Check

A symptom does not tell you by itself which inspection level is required, but it can change what the inspector needs to investigate. Stop using the fireplace if you suspect damage, and arrange an inspection before lighting another fire.

• A fire or possible chimney-fire event — Tell the inspector what happened and when. Heat can damage parts of a chimney that are not visible from the firebox, which is why a Level 2 inspection is commonly recommended after a fire.
• A recent storm or other weather event — Report visible changes or damage and request an assessment. A closer inspection may be needed if the event could have affected areas outside the normal line of sight.
• Smoke entering the room — Stop using the fireplace until the cause is assessed. Smoke can point to a venting or blockage problem; mention when it happens and whether it began after a change to the appliance or chimney.
• A new appliance, fuel or liner — Share the details of the change before using the system. The chimney and flue need to be evaluated in the context of the appliance and fuel now connected to them.

How Long the Inspection Takes and How to Book

There is no single visit length for all three levels: Level 1 covers accessible visual checks, Level 2 adds a video scan and other accessible areas, and Level 3 can involve opening concealed sections. The inspection level, access and findings affect how much work is involved. When you book, describe the chimney and the reason for the visit so we can explain the planned scope clearly.

Chimney inspections start at $39. Ohio Chimney and Fireplace is open 24 hours a day, 7 days a week; call (380) 234-1398 or contact us to book. You can also review the chimney inspection service to see how it fits with your concern.

What to Do After the Chimney Inspection

Ask for the findings in clear terms: what was checked, what could not be accessed, and whether the next step is cleaning, repair or a more extensive inspection. If a defect is identified, ask how it affects safe use before lighting another fire.

A recommended repair should connect to a specific finding, not just a vague warning.

Trusted Guidance on Chimney Inspection Levels

The CSIA Level 2 masonry chimney procedure outlines situations such as appliance changes, property transfers, relining and damage events that call for Level 2 consideration, along with its video-scan requirement. The CSIA homeowner resources also cover inspection and sweeping guidance.

Use these references to understand the inspection scope, then base the decision for your chimney on its actual history and condition. A sweep can explain which level applies and what the findings mean before you decide on further work.
