Mixed housing

Older neighborhoods near Reading have mid-century homes; newer subdivisions have larger homes from recent decades. Older homes need attic sealing, cellulose to depth and rim foam. Newer homes usually need targeted work on rim joists, bonus rooms and attic hatches.

Retail corridor

The 5th Street Highway (U.S. 222 Business) holds the retail district for Reading's northern suburbs, including the former Fairgrounds Square Mall.

River and mountains

The Schuylkill River forms the western boundary, and the eastern part of the township lies in the South Mountains. Homes on higher ground see more wind; air sealing helps more there.

Older-home cautions

In older homes near the Reading border, we check for knob-and-tube wiring, vermiculite and chimney gaps first. In newer homes, we focus on the rim joist, the attic hatch and recessed lights.
