A radon mitigation inspection is an evaluation performed by a licensed radon mitigation contractor to determine the appropriate type of mitigation system to install and ensure that the system is properly installed and effectively reducing radon levels to a safe level. The inspection typically includes the following steps:
Radon testing: The contractor will first conduct a radon test to determine the level of radon in the indoor air. This test may be performed using a long-term or short-term test kit, or a continuous radon monitoring device.
Evaluation of the building: The contractor will evaluate the building to determine the appropriate type of mitigation system to install. Factors such as the size and layout of the building, the foundation type, and the level of radon present will be taken into consideration.
Design of the mitigation system: Based on the evaluation of the building, the contractor will design the mitigation system, including the placement of the suction point, piping, fan, and vent.
Installation of the system: The contractor will install the mitigation system components, including cutting a hole in the foundation or slab to insert the suction point and piping, and connecting them to the fan and vent.
Sealing of gaps and cracks: The contractor will seal any gaps or cracks in the foundation or slab to prevent radon from entering the building.
Post-mitigation testing: After the system is installed, the contractor will conduct a post-mitigation radon test to ensure that the system is effectively reducing radon levels to a safe level.
System operation check: The contractor will check the operation of the mitigation system, including the functioning of the fan, manometer, and other components.
The radon mitigation inspection is important to ensure that the system is properly designed, installed, and functioning effectively to reduce radon levels in the indoor air.
