Why Radon Testing in Hockessin, DE Is Especially Important for New Castle County Homeowners
Hockessin sits in northern New Castle County, and the geology here matters more than most homeowners realize.
Delaware’s Department of Health and Social Services has identified northern New Castle County as a high-potential area for elevated indoor radon levels, driven by the presence of granitic rock formations beneath the surface. When uranium in that bedrock breaks down naturally, it releases radon gas that can seep upward into your home through foundation cracks, sump pits, and gaps in floor slabs.
Delaware falls within EPA Zone 2 (moderate potential), where average indoor radon screening levels range from 2 to 4 pCi/L. But averages do not protect your family — only your home’s specific test results can.
Hockessin is a quiet, heavily wooded community with many older homes that have basements and crawl spaces. Those environments create ideal conditions for radon accumulation.

We built three distinct packages so you can choose the level of protection that fits your home and your budget. Every package is designed exclusively for residential homeowners — we do not serve commercial clients.
Here is exactly what each package includes and what it costs:

Radon Testing in Hockessin: Understanding the Health Risk in Your Own Home
Radon forms when uranium in soil and rock decays naturally. It rises through the ground and enters homes through foundation cracks, gaps around pipes, floor drains, and sump pits.
Once inside, radon becomes trapped — especially in basements and lower floors where Hockessin homes tend to have limited air circulation during the colder months. The gas breaks down into radioactive particles that attach to dust and are inhaled into lung tissue.
Long-term exposure is the core danger. A person living in a home with elevated radon levels for years is accumulating a significant health risk that is entirely invisible without testing.
The EPA states plainly that there is no known safe level of radon exposure. Even levels below the 4 pCi/L action threshold carry measurable risk, which is why the EPA also encourages homeowners to consider mitigation when results fall between 2 and 4 pCi/L.
The only way to know your home’s radon level is to test it. That is a fact that applies to every home in Hockessin, regardless of age, size, or construction type.
