Real Estate Radon Testing for Buyers, Sellers and Agents
Real estate transactions move quickly, and radon testing should not slow them down. RADON & CO provides professional 48-hour radon testing for buyers, sellers, agents, transaction coordinators, and property managers throughout Montgomery County.
Built for contract timelines
We focus on fast scheduling, clear communication, and clean electronic reports that help keep your transaction moving.
Agent-friendly access
Sentrilock access may be available when authorized. We can also coordinate with listing agents, homeowners, tenants, or property managers depending on the property.
Montgomery County sale context
Montgomery County requires most single-family homes to be tested for radon before sale, with the test performed less than one year before settlement. Buyers and sellers should confirm the current transaction requirements with their agent or settlement team.
What happens if results are elevated?
RADON & CO specializes in independent radon testing. If levels are elevated, we explain the report and recommend speaking with a qualified mitigation professional for mitigation options.
