Radon mitigation in Indianapolis, done from measurement outward

A short-term test typically runs a minimum of 48 hours under closed-house conditions, which is the format normally used during a real estate inspection period. A long-term test using an alpha-track detector runs 90 days or more and gives a better picture of your annual average. Continuous monitors record hourly data across the same short-term window.

Most homes here are fixed with active sub-slab depressurization. A suction point is cut through the slab, a fan draws soil gas from beneath the foundation, and a sealed pipe routes it above the roofline where it disperses. The fan keeps the area under the slab at a slightly lower pressure than the house, so soil gas follows the pipe instead of entering through cracks and penetrations.

Residential mitigation commonly falls in a range of roughly $800 to $2,500 nationally, and complex homes with multiple suction points, deep finished basements or combination foundations sit at the higher end. Crawl space work adds membrane material and labor. Only an on-site evaluation of your foundation, slab condition and routing options can produce an accurate number.

Yes. A post-mitigation test verifies the system is actually achieving the reduction it was designed for, and it is the only objective proof the work succeeded. The EPA also recommends retesting at least every two years afterward, and again after major renovations, HVAC changes or foundation work that can alter how air moves through the house.
