Environmental Inspection Services is ready to send our radon inspectors, certified by the National Radon Proficiency Board, to help you assess radon levels in your home. Elevated radon levels are a major hazard to your health – radon trails only smoking as a cause of lung cancer worldwide.

In Los Angeles, approximately 6% of homes have elevated radon levels, according to the California Department of Public Health. The geology of some locations in Los Angeles predisposes them to high radon. Areas with higher likelihood of radon include the following zipcodes:

90010 (Koreatown), 90025 (West Los Angeles) , 90026 (Echo Park), 90027 (Griffith Park and Los Feliz), 90032 (Montecito Heights), 90039 (Atwater Village, Glendale), 90043 (Park Mesa Heights), 90045 (Westchester), 90049 (Brentwood), 90057 (Westlake), 90065 (Mt. Washington, Cypress Park, Glassel Park, Glendale), 90066 (Mar Vista), 90068 (Hollywood Hills), 90077 (Bel Air, Beverly Glen), 90078 (Hollywood)
