At or above 4.0 pCi/L the EPA recommends mitigation. Below it, no action is required.

Built to perform

Turnaround

Results in Two to Three Business Days

The measurement runs a minimum of 48 hours under closed-house conditions.

From placement to report in hand is typically two to three business days, so a test ordered at the start of an inspection period leaves room to act on the result.

Scheduling

Built Around Inspection Deadlines

Tell us the deadline when you book and we schedule backward from it.

If the window is tight, say so on the first call. That changes how we sequence the placement.

Reporting

Reports Your Client Can Read

The report leads with the number and what it means, then shows the hourly data behind it.

Clients in the middle of a transaction want to know whether the house is above 4.0 pCi/L and what happens next.

Seller Side

Testing Before a Listing Goes Live

A pre-listing test moves the question out of the negotiation.

If the number is low it becomes a disclosure you can make with confidence. If it is high, the seller can mitigate on their own timeline instead of under a buyer deadline, which is almost always the cheaper outcome.

Escalation

When a Mitigation Quote Is Needed Fast

If a test comes back high, the next question is what mitigation costs.

We install systems as well, so we can put a quote in your hands without you sourcing a second contractor. There is no requirement to use us for the mitigation.

Volume

Working With Brokerages

If your office runs steady transaction volume, we can set up a single point of contact for scheduling rather than starting fresh on every listing.
