Lawrenceville is Gwinnett County’s seat and one of the region’s highest-volume real estate markets. The city’s housing spans from 1920s bungalows near the historic courthouse square to active new construction along Sugarloaf Parkway. SafeAir provides the independent, certified radon test that buyers and homeowners need with results in 48-72 hours and no mitigation conflict of interest.
Jeremy Shelton has been testing Lawrenceville 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 Lawrenceville with results in 48-72 hours. We test and report. We do not mitigate.

Yes, and Lawrenceville’s measured radon average meets the EPA action threshold.
Gwinnett County is EPA Zone 2, and Lawrenceville’s measured radon average of approximately 4.1 pCi/L meets the EPA action threshold of 4.0 pCi/L. USGS mapping of the Lawrenceville area documents five distinct metamorphic rock units beneath the city: amphibolite, biotite gneiss, button schist, granite gneiss, and quartzite-aluminous schist. Each contains uranium concentrations in the 2 to 5 parts per million range typical of Piedmont granites. Seasonal expansion and contraction of the clay-rich Piedmont soils creates foundation movement that compounds aging crawlspace and slab foundation seals over time.
The Gwinnett County Extension Office at 750 South Perry Street, Lawrenceville distributes radon test kits and confirms that 22 to 28 percent of tested homes in the county have shown elevated levels. Lawrenceville’s real estate transaction volume as the county seat is among the highest in Gwinnett, and radon testing comes up on nearly every purchase contract.
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.
Lawrenceville’s residential market ranges from 1920s-1950s bungalows near the historic courthouse square to 1980s-1990s swim-tennis subdivisions to 2020s new construction along Sugarloaf Parkway. USGS mapped five distinct metamorphic rock units beneath the city, all uranium-bearing.
Downtown Lawrenceville’s oldest homes, built in the 1920s to 1950s around the 1885 courthouse, were constructed with crawlspace and pier-and-beam foundations standard for that era. These properties predate radon awareness by decades and have not been included in county-wide testing surveys.
River Colony (late 1980s to mid-1990s) and Collins Hill Park (1970-1999 primary stock) feature a mix of crawlspace and slab foundations typical of their respective eras. Chandler Pond (mid-1990s) is documented in local listings as having both basement and slab construction, notable for an area where Piedmont topography typically discourages below-grade building.
Jacobs Farm, Edgewater, and Sugarloaf Parkway corridor subdivisions from the 2000s and 2010s are predominantly slab-on-grade. Radon enters slab homes through control joints, utility penetrations, and expansion cracks. The USGS-documented biotite gneiss and granite gneiss beneath the area generates radon regardless of construction era.
Active new construction including Alcovy Trace (Century Communities, 2024), Alcovy Village (Rockhaven Homes, 2024-2026), and Inverness at Sugarloaf (D.R. Horton) are slab-on-grade. New construction is no guarantee of low radon levels. Radon enters through all slab penetrations and joints from the uranium-bearing Piedmont bedrock below.
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.
Calibrated continuous monitor set in your lowest livable level.
Hour-by-hour readings recorded. No need to be home.
Certified written report, reviewed with you directly.
Radon comes up on most Lawrenceville 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 Lawrenceville 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 Lawrenceville and the surrounding Gwinnett County area, including:
If your neighborhood isn’t listed, we still test there.
Gwinnett County is EPA Zone 2, with a Lawrenceville-specific measured average of approximately 4.1 pCi/L at the EPA action threshold. USGS mapped five distinct metamorphic rock units beneath Lawrenceville, including biotite gneiss and granite gneiss with uranium concentrations of 2 to 5 parts per million. The Gwinnett County Extension Office distributes radon test kits directly and cites a 22 to 28 percent elevated-home rate across the county. Crawlspace bungalows near the historic square, 1990s subdivisions with some documented basement construction, and 2020s new construction on Sugarloaf Parkway all sit above the same radon-generating bedrock. Foundation age and type affect entry risk, but no home is exempt from the underlying geology.
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 Lawrenceville 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 Lawrenceville 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 Lawrenceville 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.
