Understanding the Level I and II Chimney Inspections

Regular chimney inspections are essential to ensure the safety and functionality of your fireplace and heating system. The National Fire Protection Association (NFPA) recommends different levels of chimney inspections based on your chimney and fireplace’s specific circumstances and needs. Two of the most commonly performed chimney inspections are Level I and Level II chimney inspections. Let’s delve into the details of each to help you understand their purpose and when they are needed.


Level I Chimney Inspection

A Level I chimney inspection is the most basic and commonly performed type. It is typically recommended when there have been no changes to the chimney system, no known issues, and the fireplace or heating appliance has been in regular use without any problems.


When is a Level I Inspection Appropriate?

  • Routine Maintenance: A Level I inspection is typically sufficient if you use your fireplace or heating appliance regularly and have been diligent about annual maintenance.
  • No Known Issues: A Level I inspection is appropriate when there are no signs of chimney problems, such as unusual odors, visible damage, or performance issues.


What Happens During a Level I Inspection?

During a Level I inspection, a certified chimney sweep will visually inspect the accessible portions of the chimney inside and outside the home. They will check for any obstructions or buildup of creosote, a flammable byproduct of burning wood, and ensure that the chimney is structurally sound and without any obvious damage.


Level II Chimney Inspection

A Level II chimney inspection comprehensively evaluates your chimney and heating appliance system. It is more detailed and involved than a Level I inspection and is typically recommended in specific situations where there is a need for a deeper assessment.


When is a Level II Inspection Appropriate?

  • Changing Appliances: If you are changing the type of heating appliance in your home, a Level II inspection is needed to ensure that the chimney is compatible with the new appliance and meets the necessary safety requirements.
  • After a Chimney Fire: If a chimney fire has occurred, a Level II inspection is essential to assess the extent of damage and ensure safe use in the future.
  • Visible Damage or Performance Issues: If there are signs of chimney problems, such as leaks, cracking, or poor performance, a Level II inspection can provide a more in-depth evaluation to pinpoint the issues accurately.


What Happens During a Level II Inspection?

A Level II chimney inspection includes all the elements of a Level I inspection. Still, it also involves a closer examination of the chimney’s interior using video scanning technology or other specialized tools. This allows for a thorough assessment of the flue liner, chimney walls, and joints. It can reveal hidden damage or problems that may not be visible with a simple visual inspection.
