Five Forks is an unincorporated community in eastern Greenville County, about 11 miles from Greenville. Like the rest of the county, it falls in EPA Zone 1, the highest radon-potential category and the only Zone 1 county in South Carolina.
State radon program data backs that up. Greenville County's 5,220 initial home tests through June 2022 averaged 3.4 pCi/L, with a maximum of 126.6. The EPA's action level is 4 pCi/L, and it suggests considering a fix between 2 and 4.
Because radon moves up from the soil and varies from lot to lot, the EPA advises testing every home, new or old. The EPA estimates radon is the leading cause of lung cancer among non-smokers, so it's worth a few days with a test kit.
Newer homes, high ownership
Five Forks was mostly rural until the early 1990s. Its population more than doubled from 8,064 in 2000 to 17,737 in 2020, and Greenville County adopted an area plan for it in 2021 to guide continued growth. About 87% of homes are owner-occupied, and the median home value is around $452,200.
That growth means many Five Forks homes were built in the last few decades. Greenville County is the only SC county whose residential code includes radon-control methods for new homes, so some newer houses already have a passive vent pipe. If a test shows elevated radon, adding a fan to that pipe is often the most direct fix.
For homes without a pipe, the foundation decides the system. Slab and basement homes usually get sub-slab depressurization. Crawl space homes usually get a sealed membrane with suction beneath it. Combination foundations need both. Permits for unincorporated areas go through Greenville County Building Safety.

Five Forks radon FAQ
Does a newer Five Forks home already have radon protection?
Possibly. Greenville County's residential code calls for radon-control methods in new homes, which often means a passive vent pipe under the foundation. Look for a labeled pipe in a closet, garage or attic. Even with one, test the home. Passive systems don't always bring levels below 4 pCi/L, and a fan can often be added.
Will a radon system affect my home's look or value?
A radon system is a visible pipe and fan, so we plan routing with appearance in mind, often through a garage or along a less visible wall. Many buyers see a working system with recent low test results as a plus, since it answers a common inspection question. Our written quote shows where the pipe will go.
What's the typical cost for a Five Forks radon system?
As a typical estimate, sub-slab systems run $900–$2,500, crawl space membrane systems $1,500–$3,500, and combination foundations $2,200–$3,800. Larger homes and complex routing push toward the upper end. We confirm the exact price after an on-site look, and estimates are free.
