How Storm Drain Backup Into House Cleanup Works in Sandown

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

   Category 3 contact often requires removal of porous carpet, pad and insulation.

4. Dry and verify the structure

   Dehumidifiers and directed airflow dry remaining materials while meter readings show progress.

What to Do Before the Crew Arrives

Porous materials need attention after outside flooding. When left wet, they can support mold before two days have passed.

• 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.
