ACAC COUNCIL-CERTIFIED · IICRC CERTIFIED · INDEPENDENT RADON TESTING SINCE 2009
★ 5.0 · 156 REVIEWSMON–FRI 8AM–5PM
Grayson’s growing residential communities in Eastern Gwinnett County include new construction and established subdivisions where radon levels can vary significantly between neighboring homes on the same street. SafeAir provides certified, independent radon testing in Grayson with results in 48-72 hours.
Jeremy Shelton has been testing Grayson homes for indoor air quality problems since 2009. He founded SafeAir after discovering a mold infestation in his own crawlspace had affected his health for more than a year. Radon is different from mold in every way but one: you can’t know it’s there without a test.
SafeAir provides ACAC & IICRC-certified radon testing across Grayson with results in 48-72 hours. We test and report. We do not mitigate.

Yes, and Grayson’s newer construction is not a reason to skip testing.
Gwinnett County is classified as EPA Zone 2, where between 22 and 28 percent of tested homes exceed the EPA action level of 4.0 pCi/L. Grayson sits in the eastern reaches of Gwinnett County on Piedmont Province crystalline rock, where uranium-bearing metamorphic formations generate radon throughout the local soil column. Documented test results in Gwinnett County basements and crawlspaces have exceeded 15 pCi/L in some cases.
Approximately 82 percent of Grayson housing was built after 2000, making it one of the newest communities in Gwinnett County. New construction is no guarantee of low radon: slab penetrations, utility sleeve gaps, and slab-to-stem-wall joints are rarely sealed to a radon-resistant standard. Radon levels between neighboring homes in the same subdivision can differ by a factor of five or more.
Zone data gives you a probability. A test gives you your actual number.
According to the U.S. EPA, radon is the second leading cause of lung cancer in the United States.
With 82 percent of homes built after 2000, Grayson’s housing is newer than most of Gwinnett County, but new construction carries its own radon risk.
Grayson’s largest subdivision communities rely on poured concrete slab construction. Radon enters through shrinkage cracks, plumbing penetrations, and the perimeter slab-to-stem-wall joint. None of these seams are built to a radon-resistant standard in Georgia’s housing code. Testing at closing is the most reliable way to know a new home.
Some earlier Grayson subdivisions were built on crawlspace foundations, particularly on sloped terrain in the Cooper Lakes and Heritage at Grayson areas. Open or unencapsulated crawlspaces allow soil gas direct access to the floor system. Gwinnett County’s crystalline bedrock makes elevated readings in crawlspace homes more common than owners typically expect.
Energy-efficient two-story homes in Pebble Creek Farm and Wheatfields are built to tight construction standards that reduce air exchange. Reduced ventilation concentrates whatever radon enters through the foundation, making levels in these homes higher than they might otherwise be. Baseline testing is worthwhile even when a home appears to be in good condition.
Larger custom homes in Falcon Ridge and Middleton are built on varied terrain with crawlspace and walk-out basement configurations. Basement foundations in direct soil contact consistently produce the highest radon readings in a given area. Estate-lot homes in East Gwinnett’s crystalline rock terrain are a priority for first-time testing.
Whatever your home type, the continuous monitor goes in your lowest livable level. The result is specific to your property, your foundation, your soil.
Jeremy or a SafeAir consultant places a calibrated continuous monitoring device in the lowest livable level of your home. The device records radon readings hour by hour over 48 hours.
Continuous electronic monitors produce significantly more data than charcoal canister kits. Their results are accepted by lenders, buyers’ agents, and real estate attorneys throughout Georgia. The $15 UGA Extension kit works for general awareness. It does not work for real estate transactions.
After device pickup, your written report arrives within 24 hours. It documents your radon level, testing conditions, and the inspector’s certification. A SafeAir consultant reviews the findings with you directly.
You do not need to be home during the 48-hour measurement period.

Radon comes up on most Grayson contracts now. Buyers’ agents request it. Some lenders require it. The due diligence window on most Georgia contracts runs 7–10 days.
What matters in that window: you need an independent result. A company that tests and sells mitigation has a financial reason to find a problem. SafeAir tests and reports only. If the result is below 4.0 pCi/L, you’re done. If it’s above, you know before closing and you negotiate from that position.
Mitigation in Grayson typically runs $800–$2,500 depending on foundation type and system design. Knowing the number before you close is leverage. Discovering it after is not.
If scheduling is time-sensitive, note your closing date in the form. SafeAir prioritizes contingency-window requests.
SafeAir does not sell radon mitigation systems. That is a deliberate choice.
Most radon companies test and mitigate. That creates a conflict: the company that finds a problem also profits from solving it. Jeremy built SafeAir to remove that conflict. He reports what the monitor records, regardless of the result. If your test comes back elevated, he explains what the number means and what your options look like. You choose your mitigator independently.
Jeremy holds certifications through ACAC (Certified Indoor Environmental Consultant, Certified Microbial Consultant) and IICRC. He has been testing indoor air quality in Georgia homes since 2009.
SafeAir tests homes and properties throughout Grayson and East Gwinnett County, including:
If your neighborhood isn’t listed, we still test there.
Grayson and Gwinnett County are classified as EPA Zone 2, where between 22 and 28 percent of tested homes exceed the EPA action level of 4.0 pCi/L. Documented test results in Gwinnett County basements and crawlspaces have exceeded 15 pCi/L in some cases. The underlying crystalline metamorphic rock of the Georgia Piedmont Province generates radon beneath Grayson housing stock regardless of construction year. Approximately 82 percent of Grayson homes were built after 2000 on slab foundations, and new construction is not sealed to a radon-resistant standard by default, making a certified test especially important for buyers in newer subdivisions.
There are none. Radon is odorless, colorless, and produces no symptoms you would connect to it. Long-term exposure is cumulative. The only way to know if radon is present at an elevated level is a certified test.
Contact SafeAir for current pricing. For context: professional continuous monitor testing in the Grayson area typically runs $150-$300. The UGA Extension Program offers $15 charcoal kits for general screening, but those results are not accepted in most real estate transactions.
SafeAir uses 48-hour continuous electronic monitors. Your written report is typically delivered within 24 hours of device pickup. Most Grayson clients have results in hand within 3-4 days of scheduling.
The EPA recommends mitigation at that level. SafeAir provides the test and the result. We do not sell mitigation systems. If your result is elevated, we explain what it means and what your options are. Mitigation in Grayson typically costs $800-$2,500 depending on foundation type.
Georgia has no state law requiring radon disclosure or testing for home sales. However, buyers increasingly request it during due diligence, and some lenders require it on certain loan types. If a buyer requests a test and the contingency window is open, completing it before that window closes protects your transaction.
Jeremy has tested hundreds of Georgia homes since 2009.
No obligation. No upsell. Just a certified result you can trust.
