Level 2 Inspections –
A Level II inspection is more detailed and thorough than a Level I inspection and is the recommended inspection when conditions of use for the appliance or venting system are changing, or when a Level I inspection reveals the need for a more detailed inspection. Several instances where a Level II inspection is specifically recommended include:
Frequency of Inspection -
NFPA recommends that all chimneys, fireplaces and vents be inspected annually. In addition to this requirement, there are other times when chimney and venting systems should be inspected, such as:
Level 1 inspections -
A Level I inspection is the recommended level when an evaluation of the chimney system for continued service is needed and the conditions of use are not changing. This could include:
Level 3 Inspections –
A Level III inspection is the most detailed of all of the inspection types and includes inspection of concealed areas of the building. However, examination of concealed areas will be limited to areas reasonably suspected of containing hazards that cannot be evaluated otherwise.
A Level III inspection includes all areas covered in a Level I and Level II inspection, and inspection of concealed areas to investigate known or suspected problems. In as much as certain portions of a Level III inspection require destructive action to the building, the inspector will discuss these areas with the building owner prior to the inspection.
Video Scanning -
A video scan is where we use a camera system. The camera allows us to inspect the chimney from a range of just a few inches instead of just looking from the top or bottom. The camera image is viewed on a TV monitor by the inspector. Video inspections may be recommended if the customer or sweep suspects certain problems. Video inspections are often recommended after a chimney fire or some other form of damage to a chimney, and are a routine part of a Level II or Level III inspection.
Even the most thorough inspection will not reveal all problems. Some areas of a chimney simply are not accessible due to construction of the house. Please discuss any specific concerns you have with us. The recommended inspection technique will often be based on your comments and concerns. We are trained to perform the appropriate level of inspection based upon the use of the chimney and any performance problems or safety concerns using the NFPA 211 as our standard.
