Radon Questions and Answers
What do radon professionals do?
Radon professionals place and retrieve radon test devices or monitors, interpret results, and install mitigation systems, often a vent pipe and fan that draws radon from beneath the foundation and vents it outdoors.
When should I test for radon?
Test if your home has never been tested, when buying or selling, after finishing a basement or making major changes to the foundation, and again after a mitigation system is installed. If levels are high, a sub-slab depressurization system that vents radon from beneath the home is the most common fix.
How do I choose a radon contractor?
Ask whether testers and mitigators hold credentials recognized in your state, such as through national radon proficiency programs, since some states license radon professionals. Ask how they will test after installation to confirm results.
What affects the cost of radon testing or mitigation?
Testing cost depends on the type and duration of the test. Mitigation cost depends on foundation type, soil conditions, the system design, pipe routing, electrical work and post-mitigation testing.
How should I prepare for a radon test?
Follow closed-house conditions if instructed, keeping windows and outside doors closed except for normal entry for the test period. Do not move or disturb test devices, and give the tester access to the lowest lived-in level.
