★ 5.0 · 156 REVIEWSMON–FRI 8AM–5PM
Norcross spans nearly 140 years of residential construction, from 1889 Victorian homes in the National Register Historic District to 1970s ranch neighborhoods along Jimmy Carter Boulevard and 1980s slab subdivisions throughout the city. Gwinnett County testing data shows a Norcross city average near 4.2 pCi/L, above the EPA action level of 4.0 pCi/L. SafeAir provides independent, certified radon testing throughout Norcross with same-day scheduling and lab-grade results in 48-72 hours.
Jeremy Shelton has been testing Norcross 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 Norcross with results in 48-72 hours. We test and report. We do not mitigate.

Yes, and Norcross has one of the highest city-level radon averages in Gwinnett County.
Gwinnett County is EPA Zone 2, and city-level data places the Norcross average near 4.2 pCi/L, above the EPA action level of 4.0 pCi/L. The Gwinnett County Extension Office distributes radon test kits and cites an elevated-home rate of 22 to 28 percent across the county. The underlying granite-gneiss bedrock contains uranium concentrations of 2 to 5 parts per million, the primary driver of radon generation in this area.
The Historic Norcross district, listed on the National Register and anchored by Victorian homes from 1889, holds one of Gwinnett County’s highest concentrations of open crawlspace construction. The 1970s ranch era along Jimmy Carter Boulevard added pier-beam and slab homes. Post-1980 construction shifted predominantly to slab. Three distinct construction generations mean radon risk varies street by street across the city.
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.
Norcross’s three distinct construction eras each carry a different radon entry profile, making property-specific testing the only reliable approach.
The National Register district near Norcross Town Square includes Victorian and craftsman homes from 1889 to 1920, almost all with open or vented crawlspace construction. These structures sit directly on granite-gneiss saprolite without vapor barriers, providing the most direct soil-gas pathway of any foundation type in the city.
Norcross’ suburban expansion in the 1970s added ranch neighborhoods along Jimmy Carter Boulevard with a mix of pier-beam and slab foundations. The Jones Bridge and Holcomb Bridge corridors represent this era. Foundation type varies house by house, and testing is the only way to know entry risk for a specific property.
Peachtree Station, Medlock Crossing, and Summerour-area subdivisions represent the 1980s shift to slab-on-grade. Radon enters through concrete joints and utility penetrations in the same Gwinnett granite-gneiss geology. Slab homes in Norcross test elevated more often than owners expect given the area’s measured average.
Newer townhome and condo development near the Norcross historic core uses modern construction methods. Tighter building envelopes reduce natural air exchange, concentrating whatever radon enters through the foundation. Zone 2 geology means baseline testing is worthwhile in all unit types.
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.

Radon comes up on most Norcross 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 Norcross 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 Norcross and the surrounding Gwinnett County area, including:
If your neighborhood isn’t listed, we still test there.
Norcross and Gwinnett County are classified as EPA Zone 2, with a Norcross city average near 4.2 pCi/L, above the EPA action level of 4.0 pCi/L. The Historic Norcross district, listed on the National Register with Victorian homes from 1889, has one of the highest concentrations of open crawlspace construction in the county. Crawlspace foundations without sealed vapor barriers provide a direct soil-gas pathway into living areas. The Gwinnett County Extension Office cites a 22 to 28 percent elevated-home rate across the county, and the Norcross area average sits at the higher end of that county-wide pattern.
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 Norcross 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 Norcross 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 Norcross 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.
