Radon Mitigation in Red Lion, PA
Red Lion (17356) has its own line in the state's radon database, and it is not a comforting one.
Source: PA DEP Radon Test Data by ZIP Code, closed-house short-term tests, 1990 to present, pulled Sept. 15, 2026.
About Red Lion
Red Lion was incorporated in 1880 and once produced roughly a tenth of America's cigars. The 2020 borough population was 6,512; the 17356 ZIP holds about 23,000 people and 9,360 homes. The largest housing cohort was built before 1940.
What the numbers mean here
Red Lion's basement average is four times the EPA action level and a third higher than York's worst zip. Pre-1940 homes here often sit on stone foundations with dirt or thin concrete floors, which are the hardest to depressurize and most likely to need two suction points or a sub-membrane system.
Who serves Red Lion
Absolute Radon Mitigation in East York is about 10 minutes away; Central Penn Radon and Lancaster-side firms also cover Red Lion. Every firm must be DEP-certified; check the York County certified list.
What it costs
Same as the rest of York County: $800 to $2,500 for a system, most near $1,000 to $1,500, plus $30 to $100 a year to run the fan. Details on the cost page.
Next steps
Test first (a free kit from lungradonkits.org is fine for a first look). If the result is 4.0 or above, get two written bids from certified firms using the vetting checklist. Retest 24 hours after the system goes on, then in the opposite season.
