The Radon Boss Badge of Compliance

With us, multifamily radon testing is simple. Before you sign an agreement, we review your construction plans. We tell you the estimated cost and how many test locations your property needs to meet HUD, FHA, Fannie Mae, or private-lender guidelines. This review is part of your free proposal. An NRPP-certified Radon Measurement Professional (RMP) calculates the number and placement of tests. The RMP also writes a QA/QC plan with duplicates, blanks, and equipment checks. The RMP then schedules testing to match construction turnover. We can test the whole site at once or in phases.
-
Plan & QC: RMP defines test counts/locations and the QA/QC steps to ensure defensible results.
-
Test & Conditions: Short-term kits run up to 72 hours under closed-house rules. Occupants may remain; doors and windows stay closed except for normal entry and exit. For more details, see our post on closed-building conditions.
-
Retrieve & Analyze: The RMP retrieves the kits and sends them to an independent lab for analysis.
Lastly, you receive a clear report with results and next steps. From start to finish, the final report can be delivered within 10 business days.
Does my property need radon testing? (Short answer: yes.)
While it really depends on your goals, most paths point to “yes.” Usually, if a lender is involved, testing is required. If you want a safer, more marketable property, testing is the smart move.
-
Lender compliance: If you’re financing with HUD, FHA, Fannie Mae, or most private lenders, testing is required. We review your plans (free) and tell you how many units must be tested to stay compliant, as that varies.
-
Health & liability: Radon can cause lung cancer. Testing saves lives and reduces risk for owners and tenants.
-
Marketing advantage: We turn compliance into an asset—giving you tools to showcase completed testing as a real benefit to your audience.
If you’re unsure, schedule a quick chat. We’ll review your plans, confirm your obligations, and include the unit count and cost with no obligation from you.
What happens if radon levels are high? (Short answer: retest and mitigate.)
If results come back high, the fix is to lower the levels and prove it with a re-test. Many new HUD-type multifamily buildings already have passive radon piping installed; we simply make it active by adding a fan and then verify.
-
Activate what’s built in: If passive piping exists, we add an in-line fan, seal key gaps, and re-test with a short-term test (up to 72 hours) under closed-house conditions.
-
Install if needed: If no system is in place, we install a sub-slab depressurization system—pipes and a radon fan that vent soil gas outside.
-
Pressure is the point: We create a slight vacuum under the slab so the building stops pulling soil gas inside.
After activation or installation, we re-test to confirm levels are below the compliance threshold (typically 4.0 pCi/L). Our performance goal is ≤ 2.0 pCi/L. A trusted mitigation specialist handles the work, and you receive a clear report confirming the results.
