Most Columbus homes complete radon mitigation installation in 4 to 8 hours, typically finished in a single day. The total timeline from your initial contact to completed installation is usually 3 to 5 business days. We schedule your free on-site assessment within 48 hours, design a custom system for your home, and can often install within the same week. Post-installation verification testing takes an additional 2 to 7 days to confirm effectiveness.

Properly installed active soil depressurization systems reduce radon levels by 90 to 99%, typically bringing levels well below 2.0 pCi/L (the EPA action level is 4.0 pCi/L). Our Columbus installations consistently achieve these results, verified through post-mitigation testing. We have successfully reduced radon from levels as high as 52 pCi/L down to safe ranges below 1.0 pCi/L. All systems include verification testing and warranty coverage.

Radon mitigation systems require minimal maintenance. The EPA recommends retesting every 2 years or after major home renovations. Annual DIY checks include monitoring the manometer (pressure gauge) and listening for continuous fan operation. Professional maintenance includes checking all seals, testing system efficiency, and fan inspection. Fans typically last 5 to 10 years and cost $300 to $500 to replace. We offer annual maintenance plans including inspection, testing, and priority service.

All of Franklin County is designated EPA Radon Zone 1 (highest risk), but radon levels vary based on soil composition and home construction. Areas with heavy clay soil common in Central Ohio — including Dublin, Westerville, New Albany, and Hilliard — often show higher readings. However, radon levels can vary significantly between neighboring homes due to foundation differences, soil conditions, and construction quality. The only way to know your specific risk is professional testing. Over 60% of tested Columbus homes exceed EPA action levels.

Yes, you can stay in your Columbus home during radon mitigation installation. However, we recommend planning activities away from the work area due to drilling noise and potential adhesive odors. Most installations are completed in 4 to 8 hours with minimal disruption to your daily routine. The work typically involves drilling one small hole through the basement floor, installing PVC piping, mounting a fan in the attic or exterior, and sealing foundation cracks. Your home remains fully livable throughout the process.
