Radon Testing & Mitigation in Wyomissing, PA

Wyomissing's housing stock leans newer than central Reading — most homes were built between 1950 and the 2010s, and the borough has continued to add subdivisions along the Spring Township border. Despite the modern construction, radon readings here are routinely high, and basements in the Berkshire Heights and Reading Country Club neighborhoods regularly test in the 5–12 pCi/L range.

Why newer Wyomissing homes test high

Tight construction is the reason. Modern building practices — vapor barriers, sealed rim joists, foam-sealed penetrations — are excellent at keeping conditioned air inside. They are also excellent at trapping any soil gas that does enter. A 1990s Wyomissing colonial with a poured basement frequently reads higher than a leaky 1920s twin in Reading proper, because the soil gas the older home leaks back out, the newer home holds.

Pennsylvania DEP data confirms this pattern across the entire Schuylkill Valley: newer homes do not test lower than older ones. They often test higher.

Typical mitigation in Wyomissing

Most Wyomissing homes are good candidates for a single-suction sub-slab depressurization system. The crushed-stone gravel layer beneath modern slabs communicates well, the basements are typically open and finished or finishable, and the exterior wall conditions (vinyl or hardiplank, not stone) make discharge stack routing straightforward.

Walk-through to install on a typical Wyomissing home runs about a week: walkthrough Monday, install the following Friday or Saturday, retest the Monday after.
