Why converted rowhomes need a closer look.

A 100-year-old Lawncrest row home in the 19111 blocks of Northeast Philadelphia turned up a worn flat roof with standing water, a wet basement with shifted foundation brick, a corroded water heater with an open flue gap, ungrounded outlets, and old termite tubes.

A 1946 Cape Cod near the Delaware River in Yardley turned up damp basement walls with possible mold, a dirt-floor crawl space with past water, possible asbestos floor tiles, a wet garage ceiling, and an obsolete Pushmatic panel. Why riverside Lower Bucks homes need a moisture-focused inspection.

A 1945 brick rowhome in the Logan / Fern Rock section of North Philadelphia turned up knob-and-tube wiring, a cracked stone foundation with a wet basement wall, a corroded venting chimney, an aging boiler, and a compromised garage fire barrier. Why the pre-1950 rowhouse stock needs a closer look.

On an Elkins Park inspection I called out a failing retaining wall, around $20,000 to rebuild. The agent on the deal asked me to remove it from the report. Why an independent inspector works for the buyer, not the sale.

A Delaware County buyer skipped her inspection, and a later renovation uncovered defects hidden behind finished walls. Why you should attend, and what a home inspection can and can't see.
