How Storm Drain Backup Into House Cleanup Works in Half Moon Bay

1. Assess hazards and water depth

   A crew identifies the floodwater path, sediment and wet rooms to shape the first work plan.

2. Extract standing floodwater

   Standing stormwater leaves the building through pumping matched to depth and debris.

3. Remove and clean affected materials

   The crew opens affected wall bases when contaminated materials cannot be restored in place.

4. Dry and verify the structure

   The crew adjusts equipment when humidity stays high or a cavity reading stops improving.

What to Do Before the Crew Arrives

Saturated cabinet backing may stay damp after a room looks clear. Mold growth is possible after 24 to 48 hours of wet conditions.

• Avoid using the backed-up drain or sending more water into it.
• Stay out of standing water near outlets or utility equipment.
• Keep children and pets away from contaminated runoff.
• Photograph the water path from a dry and safe position.
• Call 24/7 and report whether the drain is still overflowing.
