Common questions
Direct answers from our team. Browse all 40 questions for more depth.
How much does radon mitigation cost in Cincinnati?
Most Cincinnati homes pay $1,200–$2,400 for a complete radon mitigation system installed. Crawl-space homes run $1,800–$3,500 due to vapor-barrier work. Initial 48-hour testing is $150–$300. Free phone quotes available.
Pricing depends on foundation type (slab vs. basement vs. crawl space), system routing (interior vs. exterior), fan size required, and the post-mitigation pCi/L target. Same-day estimates after a 10-minute walkthrough.
How long does the installation take?
A standard basement or slab radon mitigation system installs in 4–8 hours. Crawl-space systems with encapsulation take 1–2 days. We schedule same- or next-week installs in most of Cincinnati.
Is radon really dangerous in Cincinnati?
Yes. Hamilton County and most of Greater Cincinnati sit in EPA Radon Zone 1 — the highest-risk classification. Radon is the second leading cause of lung cancer in the US, responsible for about 21,000 deaths annually.
Cincinnati’s underlying limestone and shale geology releases radon as it decays. Roughly 1 in 3 homes tested in Hamilton County exceeds the EPA action level of 4.0 pCi/L.
How does radon enter my Cincinnati home?
Radon enters through cracks in the foundation, sump pits, gaps around pipes, and porous concrete. Even tightly built homes accumulate radon because indoor air pressure pulls it up from soil gas.
How often should I test for radon?
EPA recommends testing every 2 years and after any foundation work, HVAC changes, or basement renovation. Real-estate transactions also require fresh testing within the past 6 months.
Should I do short-term or long-term radon testing?
Short-term (48-hour) tests work for real-estate timelines and initial screening. Long-term (90-day) tests give the most accurate average exposure. We use both depending on your situation.
Is your radon system warrantied?
Warranty terms are set by your matched partner contractor and confirmed in writing before work begins. Most Cincinnati-area mitigators offer a multi-year workmanship warranty on the install plus a manufacturer warranty on the fan. Post-install retest at 48 hours and 12 months is standard across our partner network.
Will a radon system increase my utility bills?
Minimally. The fan runs continuously and uses about 50–90 watts — roughly $5–$10 per month in electricity. Heated/cooled air loss through the system is offset by sealing work done during install.
