    • Reading Prong radon geology

      Pennsylvania records some of the highest residential radon levels in the United States, and basement-heavy construction gives soil gas a direct path indoors.

    • Row-home party walls and moisture

      Pennsylvania's brick row homes share walls and drainage problems, so one neighbor's leak becomes another's mold.

    • Cold-damp winters in leaky stock

      Century-old Pennsylvania framing with no air barrier lets cold outdoor air meet indoor humidity inside the wall.

    What Climate Zone 5A Means for Pennsylvania Homes

    Pennsylvania has the country's best-known radon geology in the Reading Prong, and elevated readings turn up statewide, not just in the southeast. Zone 5A winters meet humid summers across a housing stock heavy in brick row homes and century-old farmhouses. Basements are nearly universal here, which is where radon and moisture problems concentrate.

    • Pennsylvania Uniform Construction Code (34 Pa. Code Ch. 401-405)

      The UCC adopts the IRC and IECC statewide, with municipal opt-out affecting local enforcement.
