One of the oldest housing stocks in the country
Around 40 percent of Philadelphia homes were built before 1940, and the brick rowhome dominates the residential built form. Aging furnaces and boilers, original wiring, cast-iron drain lines, party-wall roofs and single-pane windows mean steady demand for HVAC, plumbing, electrical, roofing and remodeling work, but also a crowded field of contractors competing for each search.
