Frequently Asked Questions

How much does radon mitigation cost in Charleston?

The national average for radon mitigation is around $1,200, with most systems costing $800–$2,500. Get quotes from contractors above for accurate local pricing in Charleston.

What are the radon levels in Charleston?

Radon levels vary by neighborhood and even by home. The only way to know your home’s radon level is to test. The EPA recommends testing every home, regardless of geographic zone. If your home tests at or above 4 pCi/L, mitigation is recommended.

Do I need a radon test when buying a home in Charleston?

Yes. The EPA and most real estate professionals recommend radon testing during every home purchase. Many states require radon disclosure at sale. A short-term professional test (48–96 hours) is standard during the inspection period. If levels are elevated, mitigation can often be negotiated as a seller concession.

How do I choose a radon contractor in Charleston?

Look for contractors with NRPP or NRSB certification — these are the national credentials recognized by the EPA. Ask about their specific system design, warranty terms, and whether they include a post-mitigation re-test. Get at least 2–3 quotes.
