Frequently Asked Questions
Common questions about radon testing and mitigation.
What is radon and why is it dangerous?
Radon is a naturally occurring radioactive gas that seeps into homes through foundation cracks and gaps. It is the #1 cause of lung cancer among non-smokers, responsible for approximately 21,000 deaths per year in the United States according to the EPA. Radon is colorless and odorless, making professional testing the only way to detect it.
How much does radon testing cost?
Professional radon testing typically costs between $100 and $250 for a short-term test using continuous radon monitors (CRM). DIY charcoal test kits cost $15–40 but are less accurate. Long-term tests (90+ days) cost $25–50 for alpha track detectors. We recommend professional CRM testing for real estate transactions.
How much does radon mitigation cost?
Radon mitigation systems typically cost between $800 and $2,500 for residential properties, with the national average around $1,200. The most common system is sub-slab depressurization (SSD), which uses a fan and PVC piping to vent radon from beneath the foundation. Complex homes with crawl spaces or multiple foundations may cost more.
How long does radon mitigation take?
Most residential radon mitigation systems can be installed in 4–8 hours by a certified professional. After installation, a post-mitigation test should be conducted 24–48 hours later. The system runs continuously and typically reduces radon levels by 80–99% within 24 hours of installation.
What radon level requires mitigation?
The EPA recommends mitigation for radon levels at or above 4.0 pCi/L (picocuries per liter). The WHO recommends action at 2.7 pCi/L. There is no known safe level of radon exposure. Colorado state law requires radon disclosure in real estate transactions, and many buyers request mitigation for levels above 2.0 pCi/L.
What certifications should a radon mitigator have?
Look for NRPP (National Radon Proficiency Program) or NRSB (National Radon Safety Board) certification. In Colorado, radon mitigators must hold a state license from CDPHE (Colorado Department of Public Health and Environment). Certified professionals carry liability insurance and follow ASTM E2121 standards for mitigation system design.
