Commercial buildings — offices, retail, daycare facilities, medical, and light industrial — require multi-point continuous radon monitor (CRM) testing under EPA Protocol for Commercial Buildings. We deploy calibrated CRMs across the lowest occupied level, document HVAC conditions during the 48-hour test, and deliver a sealed report suitable for due diligence, lender review, or insurance files.

HUD-financed and many conventionally-financed multifamily properties require ANSI/AARST MAMF-2017 protocol testing of ground-contact units. We handle scheduling, tenant notification templates, ground-floor sampling at the required 10% or 25% rates, and any follow-up mitigation needed to bring buildings under 4.0 pCi/L.

Ohio schools — including the Ansonia Local School District facilities — face increasing pressure to test under ANSI/AARST MALB-2014.

Need a radon test in hand before Friday's closing? This is our specialty. We deploy a continuous monitor, return in 48 hours, and email the certified report directly to the buyer's agent, lender, and title company. If results are elevated, we can typically install a full mitigation system within 5–7 business days — often faster.

Every system we install meets ANSI/AARST SGM-SF or RMS-MF/LB standards depending on building type. That means proper pipe sizing, exterior discharge above the roofline, U-tube manometer monitoring, sealed sumps, labeled electrical, and a post-mitigation test included. Lifetime workmanship warranty on all sub-slab work.

1. Site assessment and quote. We review building plans, foundation type (slab, crawlspace, basement, or mixed), HVAC layout, and occupancy. You receive a written, itemized quote — not a phone-call estimate.
2. Protocol-correct testing. CRMs or AARST-listed devices are placed according to the standard that applies to your property type. We document closed-building conditions and weather.
3. Certified reporting. Results in pCi/L, signed by a licensed Ohio professional, formatted for lenders, insurers, school boards, or buyers.
4. Mitigation design and installation. If levels exceed 4.0 pCi/L, we engineer a sub-slab depressurization (or sub-membrane, for crawlspaces) system specific to your slab and soil. Most residential installs finish in one day.
5. Post-mitigation verification. A second 48-hour test confirms levels are below action threshold — included, not extra.
