What should we do today and this week?
Call a certified radon mitigation contractor now and ask for an estimate. Ask whether the installer has an opening this week, since a standard system is commonly installed in about a day. Tell the buyer's agent the installation date so the closing timeline can be planned.
What should we check when hiring a pro?
Verify certification through the National Radon Safety Board or the AARST-NRPP program before signing. EPA advises getting an estimate from one or more qualified contractors before proceeding. Ask the pro for proof of licence and insurance.
What does a closing-ready radon test involve?
Post-installation verification testing confirms the radon level has dropped below the action level. EPA recommends a 2-7 day measurement to check the system's initial effectiveness. A follow-up test should be done within 30 days of installation, but not sooner than 24 hours after the fan is running.
Are radon problems expensive to fix?
EPA says the cost of fixing a home generally ranges from $800 to $2,500, with an average of about $1,200. A University of Nevada Extension guide says radon problems are generally simple and cost-effective to repair. Price depends on home size, design, and which methods are needed.
