Beverly Hills properties are larger, often with extensive irrigation, mature landscaping and complex plumbing that runs a long way. More systems means more places to fail.
Irrigation is the source people least expect. A broken line running near a foundation delivers water continuously, underground, with no visible sign until something inside responds.
What goes wrong in Beverly Hills properties
Beyond irrigation, it is pool and spa equipment, water features, extensive supply runs for multiple bathrooms, and in the flats a lot of properties on slab where a leak goes sideways.
North of Sunset the ground rises and the drainage question takes over. Runoff on a slope collects against structures, and mature landscaping that has grown over decades often obstructs the drainage it was planted around.
Could my irrigation be causing damage indoors?
It can and it does. A broken line near a foundation saturates the soil against it continuously, and unlike rain there is nothing seasonal about it. Check the meter with everything off.
Does a bigger house take longer to dry?
Not necessarily longer per affected area, but bigger jobs need more equipment running simultaneously and that has to be planned around the electrical supply rather than assumed.
