When should I schedule mitigation before winter?
Winter heating traps radon gas inside homes, often raising indoor levels. Scheduling mitigation before temperatures drop ensures your system is active during peak exposure months. A qualified mitigator can install the system in less than a day, minimizing disruption. Acting now prevents prolonged exposure to elevated radon concentrations during the colder season when windows remain closed.
What certification must the installer hold?
Kentucky law requires all radon mitigation professionals to hold state certification under KRS 309.430 to 309.454. General handymen cannot legally perform this work after January 1, 2013. Verify the contractor holds NRPP or NRSB certification through the state radon office. Hiring an uncertified individual violates state regulations and may result in ineffective mitigation systems that fail to protect your home.
How effective is a professional mitigation system?
Professional sub-slab depressurization systems can reduce indoor radon levels by up to 99 percent. The EPA recommends fixing homes with concentrations at or above 4 pCi/L. A qualified mitigator estimates costs based on your home’s foundation type and design. Retesting within 24 hours to 30 days after installation confirms the system lowers radon to safe levels effectively.
What factors influence the final mitigation cost?
Costs vary based on home size, foundation design, and existing structural features. The American Lung Association notes prices range from $1,000 to $2,500 or more. Complex foundations or multiple zones may increase the price beyond the standard range. Ask the pro for a detailed quote that accounts for your specific home layout and any necessary upgrades to ensure proper airflow.
What maintenance is required after installation?
Retest your home every two years after mitigation to ensure continued safety. The EPA advises retesting within 30 days of installation to verify initial success. Monitor the system fan regularly to ensure it operates continuously. Contact a certified professional if you notice changes in radon levels or system performance to maintain optimal indoor air quality throughout the year.
