Every step, in the order it happens, with the timings

From your first message to a report

Seven steps. Most of the elapsed time is the test itself, not the administration — a short-term test is placed within days of your inquiry and the laboratory result follows the device back.

1. 01

   5 minutes

   Handled by you

   Tell us about the property

   Age of the home, foundation type, whether a basement is finished, what the lowest lived-in level is, and whether this is for a transaction with a deadline. That is enough for us to recommend the right test and quote it.

   • A photo of the basement or crawlspace saves a lot of guessing
   • For a transaction, tell us the closing date first
2. 02

   Same day

   Choose the test

   Short-term for a fast answer, long-term for an annual average, continuous monitoring when a third party will rely on the result. We will tell you which one actually answers your question rather than the one that costs the most.

3. 03

   12 hours before

   Handled by you

   Prepare the building

   Closed-building conditions begin 12 hours before placement. Windows and doors closed except for normal entry and exit, whole-house fans off, no construction dust.

   • We send a one-page checklist so nothing is missed
   • Air conditioning and normal heating may keep running
   • Long-term detectors are the exception: they sit through normal living conditions for 90 days or more
4. 04

   15 – 30 minutes, then 2 days to 12 months

   Handled by us

   Placement or monitoring

   We choose the location, record the device serial number and the placement on a diagram, and start the clock. For continuous monitoring we return at the agreed time to collect it and confirm the conditions held.

5. 05

   3 – 7 days, or 1 – 3 weeks for long-term detectors

   Handled by us

   Analysis

   Devices are analyzed by an accredited laboratory under our quality assurance program, which includes blanks, duplicates and control limits on top of the laboratory's own checks.

6. 06

   Same day as the report

   Shared

   Read the result with someone

   You get a written report with the concentration, the conditions, the device details and what the number means. We will walk you through it on the phone and tell you plainly whether it needs action — including when the answer is no.

7. 07

   2 – 30 days

   Shared

   Next step

   Below 2.0 pCi/L, plan to schedule a retest in two years. Between 2.0 and 3.9, confirm with a long-term test. At or above 4.0, we design mitigation. If mitigation is installed, a verification test follows between 24 hours and 30 days after commissioning.

From inspection to a system we can prove is working

The inspection is the step that decides whether the system works. Everything after it is execution: a fixed-price design, one day on site, and a test that closes the file.

1. 01

   45 – 90 minutes

   Shared

   Site inspection and diagnostics

   We walk the home with you: foundation type, slab condition and thickness, drain tile and sump, crawlspace, the route a pipe can take, and where a fan can sit without being heard in a bedroom. This is the visit that decides whether the system works.

   • We test the communication of the soil beneath the slab
   • We agree the pipe route and the fan location with you, on the spot
2. 02

   1 – 2 business days

   Handled by us

   Fixed-price design and proposal

   You receive a written scope: the method, suction point locations, pipe route, fan model, expected reduction, the verification test, and a fixed price. No allowances, no day rates.

3. 03

   The evening before

   Handled by you

   Before installation day

   Clear about a 3-foot square around the working area and make sure we can reach the electrical panel and the exterior wall. Most installs do not need the power off, but we will tell you if yours does.

4. 04

   One day, typically 6 – 10 hours

   Handled by us

   Installation day

   Coring the slab or sealing the sump, running and supporting the pipe, mounting the fan, wiring it to a dedicated circuit, sealing penetrations and labeling the system. Expect the sound of a hammer drill for part of the morning, some concrete dust which we contain and clean, and a pipe on the exterior wall when we leave.

   • We protect floors and surfaces before we start
   • One to two technicians for a standard install
   • You get a walkthrough and a demonstration before we pack up
5. 05

   End of installation day

   Handled by us

   Commissioning

   We confirm the fan is pulling, document the u-tube reading and the pipe route, attach the system label, and explain the two-second monthly check you should make.

6. 06

   24 hours – 30 days after

   Handled by us

   Verification test

   The system does not count as working until a measurement says so. We return and run a post-mitigation test, then send you the result and the comparison against the original reading.

7. 07

   Ongoing

   Shared

   Year one and beyond

   Check the u-tube monthly. Retest every two years, and after any major building change. Radon fans run continuously and are typically replaced between five and ten years; we keep your fan model on file so a swap is straightforward.

What an installation day is really like

Six things people ask about before they book, answered honestly rather than reassuringly. We would rather you were unsurprised than enthusiastic.
