Radon Services in Sioux Falls, SD

Nine service lines, all of them radon, none of them a bolt-on to a foundation repair business. Start with testing if you do not have a number yet, since the number decides everything after it.

• Radon Mitigation System Installation

  Test came back over 4.0 pCi/L? A sub-slab depressurization system pulls the gas out from under your foundation and vents it above the roofline, usually in one working day.

• Radon Testing and Inspection

  Never tested, or testing for a closing deadline? Continuous monitors give you an hour-by-hour record in 48 hours, with a signed report a title company will accept.

• Radon Fan Replacement and System Repair

  Manometer liquid gone level? Fan silent? That system stopped working, possibly months ago. Fan swaps run about an hour and we retest afterward.

• Finished Basement Radon Mitigation

  Worried a system means ripping open your finished basement? Most finished basements get routed through a closet, a mechanical chase, or the garage, with one small core hole and a patch.

• Crawl Space Radon Mitigation

  Dirt-floor crawl space under part of the house? Bare soil is an open door for radon. A sealed membrane plus a sub-membrane suction point closes it.

• Sump Pump Sealing and Radon Systems

  Open sump crock in the basement corner? An open crock vents soil gas straight into the house. Sealing it with a gasketed lid often becomes the suction point for the whole system.

• New Construction and Passive System Activation

  White pipe running up through the house that does nothing? That is a passive stack. Adding a fan and a manometer turns it into a working system for a fraction of a full install.

• Commercial Radon Mitigation

  Licensing body or insurer asking for radon documentation? Multi-zone measurement, an ANSI/AARST-compliant design, and a report package your file can actually use.

• Radon in Well Water Treatment

  On a private well outside city water? Radon dissolved in well water releases into the air every time somebody showers. Air testing alone will not find the source.
