River and creek flooding
Winter storms swell the Ventura and Santa Clara rivers and the barrancas that feed them. Homes near drainage channels and low streets take water first.
Ventura sits between the Ventura River and the Santa Clara River, and most homes were built before 1980. This page covers what usually causes water damage here, what to do in the first hour, and how to reach an independent restoration company that serves your ZIP code.

In Ventura, more than half homes were built before 1980, and about a quarter before 1960. Homes from those decades were usually plumbed with galvanized steel and cast iron. Both last a long time, but by now many are past the point where small, slow leaks start.
Rust-colored water, low pressure on upper floors and a musty smell near a wall are early signs worth acting on in a home this age.
Because homes here are built on slabs, a leak inside a wall or under the floor shows up late: a warm patch, a cupped board or a stain at the base of the wall.
Winter storms and aging supply lines are the two most common sources of damage.

Most homes have the main shutoff on an exterior wall near the front hose bib, with the meter box near the street.
If the water came from a toilet, a sewer line or outside, treat it as contaminated: see sewage backup cleanup or flood water cleanup.
The oldest housing in the area we cover is in 93001, where the median home was built in 1967. The newest is in 93004, with a median of 1980. Older ZIP codes tend to see more corroded pipe and drain failures; newer ones more appliance and fitting leaks.
| ZIP | Homes | Median year built | Built before 1980 | Renters |
|---|---|---|---|---|
| 93001 | 14,749 | 1967 | 67% | 55% |
| 93003 | 20,487 | 1972 | 68% | 42% |

California homeowners policies usually cover sudden and accidental water damage but exclude flooding and long-term seepage.

Independent restoration companies we connect callers with cover these Ventura ZIP codes:
Start within 24 to 48 hours; the EPA says materials dried in that window are much less likely to grow mold. Humid air around Ventura shortens that window, so don't wait for a dry day.
With more than half homes in Ventura built before 1980, a lot of original galvanized supply pipe and cast-iron drain line is still in service. Both corrode slowly and tend to leak at joints inside walls and under floors, where water spreads before anyone sees it.
Calls from 93001, 93003, 93004 are routed to independent restoration companies that serve those ZIP codes. We are a referral service and don't do the work ourselves.
Have the source, the affected rooms and when it started ready, and the call will go quickly.
