Radon Testing & Mitigation for Larger Buildings.

Commercial & Multi-Family Radon in Pennington County

Radon isn't only a single-family-home issue. Any building with occupied space in contact with the ground can accumulate radon — schools, daycares, offices, apartment buildings, and other commercial properties. Larger buildings bring their own testing protocols and mitigation challenges, and in many settings there are heightened expectations around testing because of who spends time in the building — children in schools and daycares especially.

Why larger buildings are different

• Testing is more involved. Commercial and multi-family radon testing typically follows protocols that call for testing many ground-contact rooms, not a single device in a basement — because radon can vary widely from one part of a large slab to another.
• HVAC drives radon behavior. Big buildings have complex heating and ventilation systems that change the pressure relationships between the building and the soil — which can pull radon in or push it out. Testing has to account for how the building's systems actually run.
• Mitigation scales up. A large slab often needs multiple suction points and larger or multiple fans, and the design has to work with the building's existing mechanical systems rather than against them.

Where it matters most

Schools and daycares are the most sensitive settings — children breathe more air for their body weight and spend years in the same building, so many jurisdictions and organizations encourage or require testing. Apartment and condo buildings raise the question of ground-floor and garden-level units, where residents live in continuous contact with the slab. Offices and retail with occupied lower levels are worth testing for the same reason any workplace is.

Property managers and owners

If you own or manage multi-family or commercial property, getting ahead of radon protects occupants and takes a liability question off the table. We can put together a testing plan across the building and, where levels come back high, a mitigation approach that fits the structure and its systems.
