ACAC COUNCIL-CERTIFIED · IICRC CERTIFIED · INDEPENDENT RADON TESTING SINCE 2009
★ 5.0 · 156 REVIEWSMON–FRI 8AM–5PM
Dacula’s east Gwinnett neighborhoods were built largely between 1990 and 2015 on fractured granite-gneiss Piedmont bedrock. Hamilton Mill, Apalachee Farms, and the surrounding communities span every foundation type, and Gwinnett County’s testing data shows elevated radon readings across all of them.
Jeremy Shelton has been testing Dacula 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 Dacula with results in 48-72 hours. We test and report. We do not mitigate.

Yes, but levels vary significantly by property.
Dacula and Gwinnett County are classified as EPA Zone 2, which predicts average indoor radon levels between 2 and 4 pCi/L. The EPA action level is 4.0 pCi/L. The Gwinnett County Extension Office cites an elevated-home rate of 22 to 28 percent across the county, and one Dacula home has been documented at 37 pCi/L in a finished basement. The underlying geology is fractured granite-gneiss Piedmont bedrock with thick uranium-bearing saprolite above it.
Dacula’s housing stock is concentrated in two eras: the 1990s suburban buildout and the 2000s to 2010s subdivision expansion. Crawlspace foundations dominated early builds; slab-on-grade became standard from the mid-2000s onward; walk-out and daylight basements appear in larger homes on rolling lots. Each foundation type has documented radon entry points.
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.
Dacula’s 1990s to 2010s construction spans crawlspace, slab, and basement foundations across dozens of subdivisions, making individual testing the only reliable approach.
Dacula’s late-1990s and early-2000s subdivisions were built predominantly on vented crawlspace foundations, where the underside of the floor contacts soil-warmed air year-round. Radon from Gwinnett’s granite-gneiss bedrock enters through the crawlspace floor and migrates into living areas through subfloor gaps, pipe penetrations, and interior wall cavities.
Dacula’s 2000s production-built subdivisions are predominantly slab-on-grade. Many homeowners assume slab construction eliminates radon risk, but expansion joints, cold-pour seams, and plumbing penetrations are well-documented radon entry points in east Gwinnett.
Hamilton Mill’s multiple sub-phases include hundreds of homes with full or walk-out finished basements on rolling east Gwinnett terrain. Basements have the largest soil-contact surface area of any foundation type, and UGA testing data confirms elevated Gwinnett readings are common: one Dacula basement tested at 37 pCi/L.
Homes in Harbins Landing Estates, Apalachee River Club, and larger east Dacula acreage lots frequently feature walk-out daylight basements that take advantage of rolling Piedmont topography. These finished walk-out spaces used as family rooms or home offices represent sustained daily exposure in the zone where radon concentrations are highest.
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.

Hour-by-hour readings recorded. No need to be home.

Radon comes up on most Dacula 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 Dacula 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 Dacula and east Gwinnett County, including:
If your neighborhood isn’t listed, we still test there.
Dacula and Gwinnett County are classified as EPA Zone 2, with a county-wide testing average near 2.7 pCi/L and 22 to 28 percent of homes measuring above the 4.0 pCi/L EPA action level. Dacula's fractured granite-gneiss bedrock and thick saprolite layer create radon migration pathways to foundations across all construction eras and foundation types. A calibrated, certified test at the lowest livable level is the only accurate measure of a specific home's radon level.
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 Dacula 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 Dacula 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 Dacula 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.
