Fountain Inn sits about 17 miles southeast of Greenville and crosses a county line. The larger share of residents live on the Greenville County side, with the rest in Laurens County.
For the Greenville County portion, the EPA designation is Zone 1, the highest radon-potential group and the only one in South Carolina. State radon program testing through June 2022 found an average initial result of 3.4 pCi/L across 5,220 Greenville County homes, with a high of 126.6.
No matter which county your address is in, the EPA's advice is the same: test every home. Fix it at 4 pCi/L or higher, and consider a fix between 2 and 4. Radon has no smell or color, so a test is the only way to know.
Fountain Inn's growth and its homes
Fountain Inn had about 10,400 residents in 2020 and an estimated 14,700 by 2025. Much of that growth is new construction, which brings radon into the conversation for new owners.
On the Greenville County side, the county residential code includes radon-control methods for new homes. A builder-installed passive pipe can help, but a test after move-in is the only way to know if it's doing enough. When it isn't, an inline fan often finishes the job.
Established homes get the system that matches the foundation. Many Upstate homes sit on crawl spaces or slabs, and older homes may have basements. Slab and basement homes usually get sub-slab depressurization. Crawl spaces usually get a sealed membrane with suction. Homes with both get a combination system, typically $2,200–$3,800.

Fountain Inn radon FAQ
Part of Fountain Inn is in Laurens County. Should I still test?
Yes. The EPA recommends testing every home regardless of county or zone, because radon depends on the soil under each house. The Greenville County side falls in Zone 1, but homes anywhere can test above 4 pCi/L. A short-term test takes a few days and tells you whether any further action is worth considering.
How long does a radon installation take?
Most homes are done in a few hours to one day. Straightforward sub-slab systems are usually quickest. Crawl spaces needing more membrane work or combination foundations may take longer. We give you the expected timeline in your written quote, keep the work area tidy, and schedule a follow-up radon test after the system has run.
Are radon mitigators licensed in South Carolina?
South Carolina doesn't issue a state radon license. When choosing a mitigation pro, look for certification through NRPP or AARST, which set national standards for testing and installation. Ask any company which technician will do your job and request their credentials. We're happy to share the details of the technician assigned to your home.
