What ceiling water stain means in Santee
In Santee, ceiling water stain is a moisture problem first and a cosmetic issue second. Santee water damage scope is shaped by 1970s-90s tract construction and the San Diego River corridor running through the city. That local housing mix shapes where we look first when this symptom shows up.
