Radon testing is the only way to know whether your York home has a problem, because you cannot see, smell or taste the gas and two identical houses on the same street can test completely differently. York County is an EPA Zone 1 area — the highest radon-potential classification — and Pennsylvania DEP data for York ZIP codes shows average basement readings well above the 4.0 pCi/L action level. That means testing is not a precaution for a few unlucky neighborhoods; it is something every home in the county should do, and the EPA recommends retesting every two years and after any renovation, HVAC change or foundation work.
We offer two kinds of testing. A short-term continuous radon monitor (CRM) test runs a minimum of 48 hours under closed-house conditions and logs hourly readings, tamper events, temperature and pressure. This is the test used for real-estate transactions in Pennsylvania because it is fast, certified and hard to manipulate. A long-term alpha-track test stays in place 90 days to a year and gives a true annual average that smooths out the seasonal swings — York basements typically read higher in winter when the house is closed up and the stack effect is pulling harder on the soil.
For buyers and sellers, timing matters. We can place a CRM in the lowest livable level within a day or two of your call, retrieve it after 48 hours, and email a certified report the same day — usually well inside a standard inspection contingency window. Sellers who test before listing, and mitigate if needed, remove the most common contingency negotiation in the York County market.
If your result comes back at or above 4.0 pCi/L, we recommend mitigation. Between 2.0 and 4.0 the EPA suggests considering it, and many families choose to. Because we are a mitigation company first, we will never sell you a test to pad an invoice; we test so we can design the right system if you need one, and we tell you plainly if you don't.
Post-mitigation verification is included with every system we install, but we also test systems other companies installed. If your manometer looks fine but you have never seen a follow-up number, or it has been more than two years since the last test, it is worth 48 hours to be sure the system is still doing its job.
