The National Fire Protection Association Standard 211 (NFPA 211) Recommends that chimneys, fireplaces, and vents be inspected annually. Inspections are performed to ensure that the ventilation paths are free from harmful deposits and blockages, compliance with clearance requirements and to ensure the chimney is structurally sound. There are three levels of chimney inspections:
Level I Inspection
Level 1 is recommended if your appliance or fireplace has not changed and you plan to use your system as you have in the past. Level 1 is strictly visual of the readily accessible area of the chimney and appliance interior and exterior where a Priddy Clean technician examines the basic soundness of the chimney system to confirm that the ventilation path is free from obstruction and harmful deposits of creosote.
Level II Inspection
Level 2 is required in the event of a home sale or if you are making any changes to your chimney system, notably a change in the fuel type. Level 2 is also required if you had had a chimney fire or following extreme weather which may have impacted your chimney. In addition to the visual examination included in level 1, a Priddy Clean technician may examine the attic or crawlspace to examine your appliance’s ventilation path.
A level 2 inspection may also include a video camera or video scan to examine the flue lining and chimney structure.
Every homeowner needs to know accurate information about their chimney’s condition. Priddy Clean offers Chim-Scan® video inspection service, which provides an exact evaluation of your chimney's interior without disturbing
Level III Inspection
When a hidden hazard is identified as a result of either a Level I or II inspection, a Level III inspection is highly recommended. This level of inspection confirms the proper construction and condition of sealed portions of the chimney structure and the flue system. Level III inspections are generally performed when investigating a harmful incident that has caused damage to the chimney or building.
