Radon Mitigation Cost Calculator Uses Pennsylvania DEP Records From 701 York County Systems

The York Radon Mitigation Guide has added a radon mitigation cost calculator to its online resources, built on Pennsylvania Department of Environmental Protection records for 701 mitigation systems installed in York County between 2024 and 2026. The tool is intended to give homeowners a data-based estimate of what a system typically costs in the local market.

The calculator works by using the reported cost range and median from those state records as reference points. According to the DEP records, the middle half of the 701 systems cost between $935 and $1,320, with a median of $1,150. The figures reflect systems reported by York County contractors to the state agency during the two-year period. Actual costs can vary with home size, foundation type, and the mitigation method selected.

The same records show that 97.4% of the reported systems tested below the EPA's action level of 4.0 picocuries per liter (pCi/L) after installation. The EPA recommends mitigation when indoor radon levels reach or exceed that threshold.

Radon is a radioactive gas that forms naturally from the decay of uranium in soil and rock. It is odorless and invisible, and the EPA identifies it as the leading cause of lung cancer among non-smokers in the United States. Testing is the only way to determine whether a home has elevated levels.

The guide describes the components of a typical radon mitigation system, including sub-slab depressurization, sealing of entry points, and venting arrangements. It also outlines the steps involved in hiring a mitigator certified by the Pennsylvania DEP, which maintains a list of certified contractors in the state.

The underlying records are available through the Pennsylvania DEP's open data portal at data.pa.gov and were retrieved on September 30, 2026. The York Radon Mitigation Guide states that its calculator is based on those records and does not represent an offer of mitigation services.

"The DEP data gives homeowners a factual starting point for budgeting," said a representative of The Company. "The reported range and the post-installation test results are the two figures most often requested by York County residents."
