I am a highly skilled home service professional who recently completed a maintenance check on a residential property. The property was equipped with a radon mitigation system, and I performed the necessary maintenance to ensure that the system was functioning properly. I checked the radon levels in the home and found that they were within the recommended range. I also inspected the system for any signs of damage or wear and tear and made any necessary repairs. Overall, the maintenance check was successful, and the homeowner was satisfied with the results.
