FAQs

Radon testing typically takes 48-72 hours using continuous monitoring devices. Short-term tests provide accurate results quickly, while long-term testing over 90 days offers the most reliable data.

The EPA recommends mitigation when radon levels reach 4 pCi/L or higher. Even levels between 2-4 pCi/L pose health risks, so many homeowners choose mitigation for any detectable radon.

Radon mitigation uses a sub-slab depressurization system with pipes and fans to draw radon gas from beneath your foundation and vent it safely outside, preventing indoor accumulation.

Yes, DIY radon test kits are available, but professional testing provides more accurate results using calibrated equipment. Professional testing is recommended for real estate transactions and mitigation decisions.

Radon testing costs depend on home size, testing duration, and equipment type. Professional testing typically ranges from basic short-term tests to comprehensive long-term monitoring with detailed analysis.

Test for radon when buying or selling a home, after home renovations, or every few years as preventive maintenance. Fall and winter often show higher radon levels.

Yes, radon mitigation systems require annual inspections and occasional fan replacement every 10-15 years. Regular maintenance ensures optimal performance and continued radon reduction effectiveness.

Radon is the second leading cause of lung cancer after smoking. This colorless, odorless gas accumulates indoors and damages lung tissue over time through radioactive decay particles.

Yes, radon levels fluctuate due to weather, soil conditions, and home ventilation changes. Previously safe homes can develop radon problems, making periodic retesting important for ongoing safety.

Yes, Minnesota has elevated radon levels due to geological conditions. Many Minneapolis area homes test above EPA action levels, making professional radon testing essential for homeowner safety.
