Why radon matters
Radon is a colorless, odorless gas and the second-leading cause of lung cancer in the U.S. It's a standard checkpoint in most home sales — a buyer's inspection flags it, and if levels are high, mitigation follows. Every professional listed here holds an active radon certification from the NRPP or NRSB.
What radon work costs
A short-term radon test typically runs $150–$300. If results come back at or above 4.0 pCi/L, a mitigation system usually costs $800–$2,500 depending on the home's foundation and layout. Get quotes from at least two certified pros before deciding.
