01 · WHAT IT IS

Radon, in plain English

Radon is a colorless, odorless radioactive gas that can enter homes from the ground. Long-term indoor exposure is a known lung-cancer risk (EPA). Testing is the only way to measure the level in a specific home — you cannot see it, smell it, or taste it.

Where it comes from

Uranium in soil and rock decays into radon gas, which seeps upward into homes through the foundation, cracks, and utility penetrations.

Why it matters indoors

Radon can accumulate in enclosed spaces (basements, first floors) to concentrations that raise long-term lung-cancer risk (EPA).

How we measure it

A continuous radon monitor logs hourly readings on the lowest occupied level for at least 48 hours, producing an average and a chart.

02 · WHY IT MATTERS

Why radon testing during a home purchase

Even homes in EPA-designated lower-risk zones can test high — zone classification is a predictive average, not a guarantee for a specific house. A short-term test during your home-inspection window gives you the result before finalizing the purchase decision.

Fits the inspection window

A 48-hour deployment slots into most due-diligence periods without holding up your closing timeline.

Zone risk is a guide, not a promise

The EPA maps counties by zone (1 highest, 3 lowest) as a predictive tool. Individual homes in any zone can test above the action level.

A number you can act on

Test data lets you negotiate mitigation, plan post-close remediation, or move ahead confidently — with a real reading, not a guess.

03 · WHAT WE DO

Independent testing — we do not sell mitigation

Home Spectors deploys a continuous radon monitor on the lowest occupied level of the home for at least 48 hours under closed-house conditions — our standard protocol. This is a short-term test; the EPA short-term testing range is 2 to 90 days depending on the device and protocol used.

We do not perform radon mitigation. Our test result is independent of any remediation sale — a straightforward reading, delivered in a written report.

What we do
  • Continuous-monitor short-term test (48h+)
  • Lowest occupied level placement
  • Written report with the raw reading and EPA action-level context
  • Referral to independent NC-licensed mitigators if warranted
What we do not do
  • Install radon-mitigation systems
  • Sell mitigation contracts
  • Refer to a single preferred mitigator (independence rule)
04 · OUR PROCESS

Three steps, one honest reading

1
Scoping call

Confirm timeline and coordinate with your general home inspection. If your due-diligence window is tight, we place radon on the same visit so nothing waits on us.

2
Monitor deployment

A continuous radon monitor is placed on the lowest occupied level for at least 48 hours under closed-house conditions (windows and exterior doors kept closed except for normal entry/exit).

3
Retrieval + written report

We retrieve the monitor and process the reading. You receive a written report with the raw data, EPA action-level context (4.0 pCi/L), and next-step guidance if the reading warrants mitigation.

05 · WHAT YOU WALK AWAY WITH

A written report, the raw data, and next-step guidance

You receive a written report with the raw radon reading, EPA action-level context, and next-step guidance if the result is at or above 4.0 pCi/L (the EPA action level).

We do not sell mitigation. If your reading warrants remediation, we refer you to independent NC-licensed mitigators so you can shop for a fair mitigation quote without pressure from your tester.

Raw data

Hourly readings and the 48h+ average — the actual monitor output.

EPA context

Where your reading falls relative to the 4.0 pCi/L action level, in plain English.

Next-step guidance

If mitigation is warranted, we refer to independent NC-licensed mitigators — never a single preferred vendor.

06 · FAQ

Radon testing — questions we hear

The EPA recommends taking action to reduce radon in homes that test at or above 4.0 picocuries per liter (pCi/L) as a long-term average. This is a health-based guideline based on long-term lung-cancer risk. Levels below 4.0 pCi/L still carry some risk, and the EPA encourages considering mitigation for levels above 2.0 pCi/L as well. Your test result is a reading — we walk you through what that specific reading means for your home.
The EPA classifies U.S. counties into three predictive zones (Zone 1 highest, Zone 3 lowest) based on geology, soil, and prior testing data. North Carolina counties fall across all three zones. Zone classification is a predictive guide only — a specific home in any zone can test above or below the action level regardless of its county classification. The only way to know your home’s actual radon level is to test it. To look up your county’s EPA zone, search “EPA map of radon zones” and find the North Carolina county map.
Yes. Zone classification is a predictive average across many homes — individual homes vary widely. The EPA explicitly recommends testing every home for radon regardless of zone. Home Spectors tests homes across the Triad every week and we regularly find readings above the action level in lower-zone counties.
Testing measures the radon concentration in your home’s air over 48 hours (short-term test, our standard) or 90+ days (long-term test, for confirmation). Mitigation is a physical installation — typically a fan and vent pipe under the slab — that reduces radon before it reaches your living space. Home Spectors tests only. If mitigation is warranted, we refer to independent NC mitigation providers.
A short-term continuous-monitor test runs for at least 48 hours in your home. During that window, doors and windows should be kept closed except for normal entry/exit. After we retrieve the monitor, we process the reading and provide a written report — no specific turnaround promise, but most reports go out within the same-week window as your general inspection report.
Radon testing is often included in a real-estate purchase inspection contingency and can be requested by a buyer or the buyer’s lender depending on the loan program. It is not part of the general home inspection by default — clients add it as a separate service. If your purchase contract calls for radon testing, we can perform it during the same visit as your general inspection.
The EPA recommends a follow-up test to confirm, then mitigation if the confirmed reading remains at or above 4.0 pCi/L. Home Spectors will explain the reading, provide the raw data, and refer you to independent NC mitigation contractors. We do not sell mitigation, so the referral is for shopping — pricing for a residential mitigation system varies by home construction and site conditions and should be quoted by the mitigation contractor.
