02 · WHO PERFORMS YOUR TEST

Owned and led by a Certified Master Inspector

Home Spectors is family-owned and has been serving Greensboro and the Triad since 2007. The company is led by Jason Michael, a Certified Master Inspector (CMI®) and North Carolina Home Inspector Licensure Board licensee — .

Radon testing is performed by an in-house Home Spectors inspector — never subcontracted. The inspector deploys the continuous radon monitor, retrieves it after the test window, and delivers the written report to you.

We have completed more than 40,000 inspections since 2007. Radon testing is an add-on we perform routinely alongside residential home inspections across the Triad.

01 · WHAT IT IS

Radon, in plain English

Radon is a colorless, odorless radioactive gas. It can seep into homes from the ground. Long-term exposure is a known lung-cancer risk (EPA). Testing is the only way to know 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.

Every Home Spectors radon test follows EPA testing protocols and the North Carolina Radon Program’s guidance. It is a measurement service, not a mitigation contract.

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. It is not a guarantee for a specific house. A short-term test during your inspection window gives you the result before you close.

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

We place a continuous radon monitor on the lowest occupied level of the home. It runs for at least 48 hours under closed-house conditions. This is our standard protocol. The EPA range for short-term testing is 2 to 90 days, depending on the device.

We do not perform radon mitigation. Our reading is independent of any remediation sale. It is a straight number 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

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

2
Monitor deployment

We place a continuous radon monitor on the lowest occupied level for at least 48 hours under closed-house conditions. Windows and exterior doors stay closed except for normal entry and exit.

3
Retrieval + written report

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

05 · WHAT YOU WALK AWAY WITH

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

You get a written report with the raw radon reading and EPA action-level context. If the result is at or above 4.0 pCi/L, we include next-step guidance.

We do not sell mitigation. If your reading warrants remediation, we refer you to independent NC-licensed mitigators. You can shop for a fair quote with no 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.

Radon results are delivered on the Spectora platform, attached to your Home Spectors residential inspection report. See what the deliverable looks like:

FOR AGENTS

Radon during a real-estate transaction

Radon testing is commonly added to a home-inspection contingency in the Triad. A short-term test runs at least 48 hours under closed-house conditions. Schedule the test window with the listing agent. That way occupants and showings do not disturb the monitor.

The radon reading is attached to the residential inspection report on Spectora. Your client and cooperating agents see everything in one package. We do not sell mitigation. That makes the reading a neutral input for your negotiation.

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. There is no specific turnaround promise. Most reports go out within the same week 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. The referral is for shopping. Pricing for a residential mitigation system varies by home construction and site conditions. It should be quoted by the mitigation contractor.
07 · PAIRS WELL WITH

Bundle testing on the same visit

Same inspector, one visit, one coordinated report. These environmental and specialty tests commonly bundle with radon:

08 · WHAT IT COSTS

What radon testing costs

Radon testing pricing depends on the size of the home. It also depends on whether we perform the test alongside a home inspection or as a standalone service. You will see the exact price in the scheduler before you confirm.

We do not charge for the follow-up conversation if your reading is elevated. If you want help reading the result, we walk you through it. Because we do not sell mitigation, the referral to independent NC contractors is at no cost.
