Inspection Services for Masonry Chimneys
Chimney inspections are very important for the safety of your home. The chimney industry is a unregulated service and leaders of the chimney industry with help from the National Fire Protection Association have developed detailed requirements regarding chimney inspections and when they should be performed. There are three levels of chimney inspection and a summary of these inspections are listed here.
NFPA level 1 chimney inspection:
When: your appliance or your venting system has not changed and you plan to use your system as normal, then a NFPA level 1 chimney inspection is a minimum requirement. A Level 1 inspection is recommended for a chimney under continued service, under the same conditions, and continued use of same appliances.
What: We inspect readily accessible portions of your chimney, exterior, interior and and accessible portions of the appliance. We inspect for basic soundness of the chimney structure, flue, appliance and chimney connections. We also look for obstructions and combustible deposits.
NFPA level 2 chimney inspection:
When: NFPA level 2 inspection is required when you buy or sell a property, operation malfunction (chimney fire & storm damage) or changes are made to the system. Changes can include a change in the fuel type, shape, or material in, the flue (i.e. relining), or the replacement or addition of an appliance of a dissimilar type, input rating or efficiency.
What: NFPA level 2 inspection will include video inspection to scan the internal portions of the flue, smoke chamber and joints of the flue. There are no specialty tools (i.e. demolition equipment) required to open doors, panels or coverings. We are looking for proper construction of accessible portions of the chimney, proper clearance from combustibles in accessible locations and size and suitability of flues for connected appliances.
NFPA level 3 chimney inspection
When a Level 1 or Level 2 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 3 inspection is recommended.
What: A Level 3 inspection may require destruction of material to determine proper condition or clearance to combustibles.
