Spray Foam Insulation in Wernersville, PA

Spray Foam Insulation in Wernersville works on homes in a borough with an interesting past. In the late 1800s and early 1900s, visitors from Philadelphia and New York came by the Reading Railroad for the mountain air of South Mountain and stayed at resort hotels like Galen Hall. The borough grew from 1,761 residents in 1970 to 2,150 in 2000 and 2,776 in 2020, on about 0.75 square miles.

Older homes

The older parts of town have houses from the resort and railroad years. They usually need attic sealing, cellulose to depth, wall dense-packing and sill foam.

Newer homes

Growth since 1970 brought newer homes that usually need targeted work: rim joist foam, attic top-ups and bonus room fixes.

Institutions

Wernersville State Hospital opened in 1891, and its original buildings still stand. The Jesuit novitiate building became a spiritual center that closed in 2021, and the Phoebe Center bought it in 2023 for senior living.

Mountain air

South Mountain rises behind the borough, and homes on its slopes see more wind. Air sealing makes a real difference there.

Code and zone

Pennsylvania's 2021 UCC took effect January 1, 2026. Berks County is in PHRC's Central zone and OpenEI's Zone 5A.

A typical Wernersville job

For an older home, a common plan is: seal the attic floor and chimney gap, blow cellulose to depth, foam the sill and rim, and dense-pack walls after checking the wiring. For a newer home, it is usually rim joist foam and an attic top-up.
