Radon Guidance for Tenants and Landlords

Renters and landlords can both have practical radon questions: who should test, what a result means, how to talk about mitigation, and what to do when a basement or lower-level living area is used often. This page explains those situations in plain language while avoiding legal advice. Tenants should follow their lease process and local guidance, and landlords should use qualified help when a mitigation system or system repair is needed. American Radon Systems is a mitigation company, so the service guidance centers on evaluating a property, installing or repairing a system, sealing sump details where appropriate, and explaining what the mitigation side can and cannot solve.
