Commercial & Multifamily Radon Services

Radon Is a Building Liability, Not Just a Home Issue

Any occupied structure in contact with the ground can accumulate radon — and when the occupants are tenants, students, or employees, the exposure question becomes a liability and compliance question. HUD requires radon assessment for many multifamily financing programs, childcare licensing increasingly expects testing, and tenant awareness is rising. Getting documented, defensible numbers on file is inexpensive insurance.

Multifamily & Apartment Testing

Multifamily radon work is a sampling-design problem: which ground-contact units, how many upper-floor controls, what duration, and what documentation the lender or agency expects. We build the test plan to the applicable standard (including ANSI/AARST multifamily protocols used by HUD lenders), coordinate access with your property manager, and deliver a portfolio-ready report — unit-by-unit results, floor plans marked, and mitigation scoping for any units over the action level.

Daycares, Schools & Offices

For childcare centers and schools, radon results are increasingly part of licensing files and parent communication. For offices and retail, testing is usually driven by due diligence, lease negotiation, or an employee concern. In all cases the pattern is the same: test the ground-contact occupied spaces to protocol, document everything, and mitigate only the specific areas that need it — commercial mitigation is targeted, not building-wide, which keeps costs rational.

Commercial Mitigation

1. Diagnostics first. Larger slabs, multiple additions, elevator pits, and mechanical rooms change how soil gas moves. Communication testing tells us how many suction points a building actually needs before anyone quotes a number.
2. Systems that respect your building. Routing through mechanical chases, roof terminations away from air intakes, fans sized for measured airflow, and work scheduled around your tenants' hours.
3. Verification and documentation. Post-mitigation testing on every treated area, with a closeout package formatted for lenders, licensors, insurers, and your own records.

Straight Answers at Building Scale

Commercial radon has more variables than residential, but the physics is the same and so is our approach: measure properly, report plainly, fix only what needs fixing, and guarantee the result. Call with your building type, square footage, and what's driving the question — financing, licensing, diligence, or a concern — and we'll scope the right plan on the phone, free.
