Radon contractors should carefully consider have both ethical, fiduciary, and legal duties when developing standard operating procedures and contracts. For example, the radon mitigation contractor may be hired and paid by the seller in a real estate transaction to whom a fiduciary duty is owed. However, the seller will not likely be the occupant of the home once the system is installed. This requires the mitigation contractor to provide concise and conspicuous information to the buyer regarding the operation and maintenance of the system and how it interacts with other systems in the home. The systems should meet national radon standards to ensure that the both the consumer and the future occupant are fully informed and afforded the health and safety anticipated from a compliant and quality installation.
The ethical duties of the radon mitigation contractor begin with  evaluating existing measurement test results to confirm test compliance and the need for the system as well as  diagnosing the radon problem and its source in order to mitigate in the most efficient and cost effective manner.
Health, safety, and consumer economics should be the first and foremost priority for the radon mitigation contractor. Third-party influences, such as real estate agent, sellers, buyers, etc., should never influence the contractor to compromise quality.
