Signs of Hidden Water
Even without a visible leak, hidden moisture can manifest in several ways. Look for unexplained water stains on walls or ceilings, peeling paint or wallpaper, warped baseboards, or soft spots in the drywall. A persistent musty odor, especially in warmer Los Angeles conditions, can also indicate trapped water. If you live in an older multifamily building, be aware that slow leaks behind cabinets or walls are common.
