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

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

The levels of a chimney inspection are Level 1, Level 2 and Level 3, each covering a different scope. Choose based on whether the chimney’s condition is unchanged, a major event or appliance change calls for a deeper review, or a suspected hidden hazard needs access.

What Are the Levels of a Chimney Inspection?

The levels describe how much of the chimney system gets examined and how much access the inspection requires. A higher level is not automatically better for every home; the right scope depends on what has changed and whether signs point to a hidden problem.

Which Chimney Inspection Level Fits Your Situation?

Start with what changed, not with a request for the highest number. A chimney professional can assess the visible condition and recommend a broader scope when the reason for inspection calls for it.

• Choose Level 1 for an unchanged setup — A routine check is generally the starting point when you have the same fireplace or stove, the same fuel, and no known damage or performance change.
• Ask about Level 2 after a significant change — A new or changed appliance, a home sale, relining work, or a chimney fire or weather event are reasons to ask whether Level 2 is appropriate. Its video scan helps examine the flue interior beyond what a visual check can show.
• Level 3 follows evidence of a serious hidden issue — This scope is not a routine upgrade. It applies when a Level 1 or Level 2 inspection points to a serious hazard and the inspector needs access to parts that are otherwise concealed.

What Each Chimney Inspection Checks

A Level 1 inspection focuses on readily accessible parts of the chimney and appliance. The inspector looks for visible problems that could affect safe operation, such as damage, blockage or an issue with how the system connects. It does not involve opening up concealed construction simply to look behind it.

Level 2 adds inspection of accessible spaces around the chimney and a video scan of the flue. The scan can reveal interior conditions that are difficult to assess from the firebox or chimney opening alone. The CSIA Level 2 inspection procedure describes the video scan requirement and situations that call for this level.

A Level 3 inspection addresses a specific concern that cannot be evaluated through the less invasive levels. Because it can involve removing parts of the chimney or nearby building materials, it should follow a clear finding—not simply the fact that the chimney is old or has not been inspected recently. To arrange a chimney inspection service, share what prompted the visit so the scope can be considered.

How a Chimney Inspection Moves From Concern to Findings

The exact work depends on the level selected and the accessible condition of the system. These steps show how to prepare safely and follow the inspection without trying to enter or dismantle the chimney yourself.

1. Identify the appliance and fuel — Note whether the chimney serves a fireplace, wood stove, or another appliance, and whether you changed the appliance or fuel. Check that your description matches the equipment you actually use.
2. Write down the reason for the inspection — Record a recent chimney or house fire, severe weather event, relining, appliance change, sale, smoke issue, or visible damage. Check your notes for dates and details that help the inspector understand what needs attention.
3. Let the appliance cool and leave it assembled — Do not use a hot fireplace or stove as a place to inspect the flue, and do not remove panels or chimney parts. Check that the fire is fully out and the appliance is cool before anyone examines the firebox.
4. Look only at visible areas from the room — From a safe position, note obvious cracks, loose masonry, debris, or a damper that does not move normally. Do not climb onto the roof or reach into the flue; check that your observations stay limited to parts you can see without a ladder or tools.
5. Ask which level matches the trigger — Share your appliance details and reason for booking, then ask whether the proposed scope is Level 1, 2, or 3 and why. Check that the recommended level accounts for any recent change or event you mentioned.
6. Confirm the Level 2 scan when that level applies — For a Level 2 inspection, ask how the video scan will be included in the inspection. Afterward, check that the findings identify the areas examined and any observed concerns.
7. Review any request for Level 3 access — If concealed areas need to be opened, ask which finding requires that access and what part may need removal. Check that the reason and proposed access are clear before agreeing to the additional work.
8. Keep the findings for the next decision — Ask for the inspection results and any recommended next step in clear terms. Check whether the issue calls for cleaning, repair, further evaluation, or no additional work at that time.

Signs Your Chimney May Need More Than a Level 1 Check

A Level 1 check may not answer every question when the system has changed or an event may have affected hidden parts. Tell the sweep what you noticed; do not try to diagnose damage from the ground or open up the chimney yourself.

• A new appliance or relining — A change in the appliance or liner can change the chimney system being evaluated. Ask whether Level 2 is needed to inspect the changed setup.
• A property sale — A sale is one of the situations in which a Level 2 inspection may be recommended. Ask what inspection scope is appropriate for the chimney and appliance being transferred.
• Fire or weather damage — An event can affect parts of the chimney that are not visible from the room. Report what happened and ask whether the inspection needs to include a video scan or broader access.
• A finding behind a visible surface — If an inspection identifies a serious concern that cannot be checked through accessible openings, the inspector may recommend Level 3. Ask what evidence points to a hidden problem and what access would be required.

How Long a Chimney Inspection Takes and How to Book

There is no single visit length that applies to every inspection level. The scope, access to the chimney, the number of connected appliances, and whether a Level 2 video scan or further investigation is needed all affect how much work is involved. Ask about the expected duration when you book, based on the inspection level and setup you describe.

To book, provide the chimney’s appliance and fuel type, note any recent changes or damage, and ask which inspection level fits the reason for the visit. Same-day service is available. You can contact us or call (267) 705-6118 to schedule.

What to Do After the Chimney Inspection Report

Use the findings to separate an observation from the next action. A report may identify a condition to monitor, cleaning or repair work, or a reason to investigate concealed areas further; ask which finding supports each recommendation and what part of the system it concerns.

If the inspection recommends repair, get the affected part and proposed work identified before deciding how to proceed.
