This can be so important and often overlooked. Thanks for the heads up!
Most homes have some sort of venting system for the heating system or gas fired water heater that vent to the exterior. Fuel fired appliances produce combustion gases that need to be vented outside. These gases often include some level of carbon monoxide and other dangerous gases that can be dangerous to the occupants if they accumulate in the living space. While a visual inspection during the course of a home inspection can tell you if components are installed properly in the readily accessible areas of the home, there is much of the chimney and venting system that can not be seen by typical meathods. Most problems in the chimney are concealed on the interior liner. Accuracy Assured Home Inspections recently aquired the technology to perform video inspections of the interior chimney liner and vents. It is recommended that chimney be inspected once a year or after a major event that would cause damage to the chimney. It is also recommended that chimneys and vents be inspected as part of any real estate transaction.
Accuracy Assured Home Inspections now provides complete chimney inspections as an additional service. All inspections are conducted to the NFPA 211 standards. The interior of the chimney liner is inspected from the roof level down to the vent connection using a special camera that is inserted into the liner. The video is saved directly to CD or DVD so that the cleint can give the information to their contractor to make any necessary repairs.
Typical defects would include seperated liner sections that can allow for dangerous combustion fumes to accumulate inside of wall cavities and make their way into the living space, broken terra cotta liner sections, obstructions from birds nests or other wildlife, cracks that can allow for moisture intrustion that can migrate to other areas of the home, etc. The inspection will also verify if chimney cleaning efforts were successful or additional work needs to be done.
Is your chimney overdue for it's annual checkup?
