Radon Testing

Why Test?

You Cannot Know Without Testing

Radon has no color, no smell, no taste. It produces no immediate symptoms. Homes that look, feel, and smell completely normal can have radon levels high enough to pose a serious long-term health risk.

The only accurate way to assess your risk is a professional radon test. The EPA recommends that all homes be tested — regardless of age, location, or construction type.

New homes can have elevated radon just as often as older ones
Neighbor's levels don't predict yours — radon varies house to house
Elevated levels can drop significantly with the right system
Testing is non-invasive, affordable, and fast

Understanding Radon Levels

Below 2 pCi/L

Low risk — no action needed

2 – 4 pCi/L

Consider mitigation

Above 4 pCi/L

EPA action threshold — mitigate

Above 8 pCi/L

High — mitigate as soon as possible

Testing Options

Which Test Is Right for You?

Different situations call for different testing approaches. We'll recommend the right test for your needs.

⚡

Short-Term Test

48-hour test using an electronic continuous monitor. Best for quick results, real estate transactions, and initial home screening.

Results within 48–96 hours
Ideal for home purchases
Required by most real estate contracts
Performed under closed-house conditions

📅

Long-Term Test

90-day to 12-month alpha track detector. Provides the most accurate picture of your home's actual annual radon exposure.

More accurate than short-term
Accounts for seasonal variation
Recommended for long-term health assessment
Passive device — no power required

🏠

Post-Mitigation Test

Mandatory follow-up testing after mitigation system installation. Confirms the system is performing as designed.

Always included with our installs
Verifies EPA threshold compliance
Provides documentation for home sales
Peace of mind that the system works

Testing Process

What Happens During a Test

1

Device Placement

We place the test device in the lowest livable level of your home — typically the basement. The location is selected per EPA guidelines for accurate measurement.

2

Closed-House Conditions

For short-term tests, windows and doors should remain closed (except for normal entry/exit) for 12 hours before and during the test period to ensure accurate results.

3

Device Retrieval & Analysis

After the test period, we retrieve the device and analyze the results. For electronic monitors, we can provide on-the-spot readings.

4

Written Report

You receive a clear written report with your radon level result, a comparison to EPA guidelines, and our recommendation for next steps — whether that's peace of mind or scheduling mitigation.

Common Questions

Testing FAQs

The test device is placed in the lowest livable level of the home — typically the basement or first floor if there is no basement. It should not be placed in a kitchen, bathroom, laundry room, or anywhere with excessive moisture, drafts, or direct sunlight.

No. You can continue living normally in your home during the test. The only requirement is maintaining "closed-house conditions" — keeping windows and doors closed as much as possible (normal entry/exit is fine) for the duration of the test.

The EPA recommends mitigation for any level at or above 4 pCi/L. We'll walk you through the options and provide a mitigation quote. In many cases, we can install a system within the same week as your test results.

The EPA recommends testing every two years in homes without a mitigation system, and after any major renovation. For homes with a mitigation system, test every two years to confirm the system is still performing effectively.
