Experienced Fireplace and Chimney Inspectors

Chimney Scientists have performed over 8,000 level 2 chimney flue inspections. We thoroughly inspect and write a 5 to 10-page report onsite for immediate delivery. The report includes not only pictures of your chimney identifying any issues and how to fix them, it includes diagrams and illustrations of a chimney’s composition, to get a better understanding of how they work and how they are constructed. The process takes about 1-2 hours.

All inspections are based on the National Fire Protection Association 211 code for safe-functioning chimneys.

Below is an explanation of inspections and what services your chimney service technician should provide as defined by the NFPA 211.

Level Two Chimney Inspection

A level two inspection is required when any changes are made to the system. Changes can include a change in the fuel type, changes to the shape of, or material in, the flue (i.e., relining), or the replacement or addition of an appliance of a dissimilar type, input rating or efficiency.

Additionally, a level two inspection is required upon the sale or transfer of a property, or after an operation malfunction or external event that is likely to have caused damage to the chimney. Building fires, chimney fires, seismic events as well as weather events are all indicators that this level of inspection is warranted.

A level two inspection is a more in-depth inspection than a level one inspection. When a level one or level two inspection suggests a hidden hazard and the evaluation cannot be performed without special tools to access concealed areas of the chimney or flue, a level three inspection is recommended.

A level three inspection addresses the proper construction and the condition of concealed portions of the chimney structure and the flue. Removal or destruction, as necessary, of permanently attached portions of the chimney or building structure, will be required for the completion of a level three inspection.

A level two inspection includes everything in a level one inspection, plus the accessible portions of the chimney exterior and interior including, attics, crawl spaces, and basements. It will address proper clearances from combustibles inaccessible locations. There are no specialty tools (i.e. demolition equipment) required to open doors, panels, or coverings in performing a level two inspection.

A level two inspection shall also include a visual inspection by video scanning or other means to examine the internal surfaces and joints of all flue liners incorporated within the chimney. No removal or destruction of permanently attached portions of the chimney or building structure or finish shall be required by a level two inspection.

Inspection Definitions:

Accessible: May require the use of commonly available tools to remove doors, panels, or coverings, but will not damage the chimney or building structure or finish.
Readily Accessible: Exposed, or capable of being exposed, for operation, inspection, maintenance, or repair without the use of tools to open or remove doors, panels, or coverings.
Fireplace Dampers: Fireplace flue liners with cracks and open mortar joints can be dangerous when combined with any creosote buildup. A quick video inspection will assure that the fireplace is a tight system. In the case that these concerning cracks and holes are found, we can offer a great repair rather than an expensive new liner.

We offer several ways to fix your chimney flue including FireGuard and Thermocrete®.
