Many Sunnyvale homes are 1950s–1960s Eichlers with flat or low-slope roofs, walls of glass and radiant heating pipes embedded in the slab.

Other risks in Sunnyvale
Water heater failures
Garage and closet water heaters burst with age, flooding nearby rooms.
Older plumbing
Older homes have galvanized supply lines and cast-iron drains that leak with age.
Hidden leaks after small quakes
Even small earthquakes can loosen water heater connections, crack old drain joints and shift supply lines inside walls, causing slow leaks that only show up weeks later as stains or odors.
First rain of the season
After months without rain, roofs, gutters and window seals dry out and crack, and the first big storm of the season is when most ceiling and wall leaks are found.
Signs you need water damage
- Standing water, wet carpet or soft, swollen flooring
- Stains or bubbling paint on ceilings and walls
- A musty smell that doesn't go away

Water Damage questions
Do I need a permit for repairs in Sunnyvale?
Cleanup and drying don't. Structural, plumbing and electrical repairs need permits from the City of Sunnyvale Building Safety division.
Is a slab leak covered by insurance in Sunnyvale?
Many policies cover the water damage and access costs from a sudden slab leak, but not the pipe repair itself. Report it quickly and keep photos and the plumber's findings.
How fast does water damage need to be dried?
As soon as possible. Mold can start growing on wet drywall and wood in 24 to 48 hours, and materials keep absorbing water the longer it sits.
Does homeowners insurance cover water damage?
Usually for sudden, accidental water such as a burst pipe or appliance failure. Gradual leaks, flooding from outside and sewer backups often need separate coverage or endorsements.
