Philadelphia County, Pennsylvania

What this place does to a house

• Philadelphia County is an EPA Zone 1 radon area — the highest band. A $15 test kit settles it; most homes here have never been tested.
• With ~88 freeze days a year, one forgotten garden hose can crack a pipe inside your wall. We'll ping you before the first freeze.
• This is a humid climate: crawlspaces and attics grow problems quietly. A 10-minute look twice a year beats a $6,000 mold remediation.
