What bubbling paint means in Tierrasanta
In Tierrasanta, bubbling paint is a moisture problem first and a cosmetic issue second. Tierrasanta water damage is shaped by the community's 1970s-80s master-plan timing and its geographic isolation as the "Island in the Hills" with Mission Trails Regional Park wrapping three sides. That local housing mix shapes where we look first when this symptom shows up.
Why bubbling paint shows up in Tierrasanta
Bubbling paint in North Park, La Mesa, Lemon Grove, and National City is treated as active moisture until meters say otherwise. In 1950s-80s stock with copper supply and cast-iron drains, pinhole copper and drain backups are the volume drivers, and moderate humidity with older envelopes that hide moisture can keep the paper face damp after the surface looks dry.
