A 4-day test gives a quick result. A 91-day test is a long average, the Health Canada method. Both are $59 before taxes. Shipping, the return and the laboratory are included.
How it works
Order, place the detector, then send it back. The laboratory receives it within 48 hours. The report goes out within 2 business days after that receipt.
Return the detector
The return is included. Open the portal and follow the steps there.
One payment. Each detector has a name, an address, and an email or a phone number. They do not all have to go to the single payment address: the address entered on the line is that detector’s address. The Shipping block at checkout remains the buyer’s address.

Installation: 3 h Investment: 2 799,99 $ + tax (standard)
Solution installed
Active sub-slab depressurization (SSD) by a C-NRPP certified crew. 1 suction point under the slab, connected to a sealed exhaust pipe; a fan creates negative pressure that intercepts radon before it enters the home.
Result
Confirmation test 48 hours after startup: 37 Bq/m³, well below Health Canada's 200 Bq/m³ action level (ideal target < 100 Bq/m³).
