Commercial buildings in Des Moines add complications a single-family home does not have: multiple HVAC zones, large open slab areas, below-grade parking, and sometimes multiple tenants with different needs on the same foundation. We approach commercial radon work as its own scope, not a scaled-up residential job.
Because IA sits in EPA Radon Zone 1, testing matters for commercial spaces too, especially schools, daycares and offices where people spend long hours indoors.
Why commercial buildings test differently
A large commercial slab often needs testing at multiple locations rather than one device in one room, since radon entry and HVAC mixing can vary significantly across a big footprint. We map out test locations based on the building's actual layout and HVAC zones instead of a single point reading.
How HVAC systems change the mitigation approach
Commercial HVAC systems actively move and pressurize air in ways residential systems do not, which can either help or work against a mitigation system depending on how it is balanced. We coordinate mitigation design with how the building's HVAC already operates rather than treating the two as unrelated.
Multi-tenant and multi-zone buildings
Buildings with several tenants or distinct zones on one foundation sometimes need more than one mitigation system, or a single system engineered to cover multiple sections. We scope this out based on the slab layout and existing foundation penetrations before recommending an approach.
Schools, daycares and offices
Spaces where people, especially children, spend extended hours indoors are worth testing proactively rather than waiting for a reason to. We work with property managers and building owners across Polk County to schedule testing around occupied hours and business operations.

Common questions
Commercial Radon Mitigation & Testing questions we hear in Des Moines
Commercial buildings often need testing at multiple locations to account for larger slabs and multiple HVAC zones, rather than a single device in one room.
Yes. We schedule testing and installation around occupied hours and business operations so it does not disrupt tenants or daily operations.
Sometimes. It depends on the slab layout and how the foundation is divided. We scope this during the initial assessment rather than assuming one system covers every tenant space.

A technician who explains the plan
Before anything gets installed, you will know why the system is laid out the way it is for your specific foundation, not a generic setup.
A result you can verify
We do not just tell you the fan is running. A post-mitigation test confirms your actual indoor radon level came down.
