Flood Cleanup After a Las Vegas Monsoon Storm
Flood cleanup after a monsoon storm treats the water as contaminated, removes mud and soaked materials, and dries what is left before rebuilding.
Why a desert city floods
The airport averages only 3.99 inches of rain a year. The National Weather Service Las Vegas office says monsoon moisture usually arrives in July and August, storms build over the mountains and move into the valley, and flash floods sweep down washes that are dry the rest of the year.
On July 8, 1999 most of a storm's rain fell in about 90 minutes. Two people died, 353 homes were damaged and public damage hit $20.5 million. On July 28, 2022 a storm flooded downtown intersections and Las Vegas Fire and Rescue answered 330 calls in one night.
Stay safe first
- Never walk or drive through moving water. CDC says six inches of moving water can knock you down.
- If you smell gas, leave and call from outside.
- Do not touch switches or cords while standing in water.
- Never run a generator or gas pump inside or within 20 feet of doors, windows or vents.
- If walls are cracked or the ceiling sags, stay out until it is checked.
What flood cleanup involves
Storm water that ran across yards and streets is black water. It carries soil, oil and whatever was on the ground. That changes the job.
- Mud and silt are shoveled and squeegeed out before any drying gear goes in.
- Carpet, pad and the lower part of soaked drywall are cut out and bagged.
- Hard surfaces get scrubbed with detergent and water, as EPA advises.
- Only then do air movers and dehumidifiers start, with readings each visit.
Insurance and flood water
Triple I says standard home, condo and renters policies exclude flood. Flood coverage is a separate policy. Water that came through a roof during the storm may be treated differently from water that rose from the ground, so write down where it came in and photograph the entry point.
