Ceiling stains in North Park, La Mesa, Lemon Grove, and National City usually track pinhole copper and drain backups are the volume drivers. The 1950s-80s stock with copper supply and cast-iron drains makes upstairs bath and roof paths the first places we check, and moderate humidity with older envelopes that hide moisture can keep a stain active longer than homeowners expect.
In Kensington, galvanized supply pinholes behind plaster and cast-iron Cat 2 backups dominate the 1920s-1930s Spanish revival stock.
