Flood cleanup in Del Mar
Flood cleanup searches in Del Mar spike when heavy storms hit the coast. Most home flooding here is surface water: runoff from streets and slopes, or high water in low-lying areas near the San Dieguito River and lagoon.
Before you go in
- Follow official alerts and do not return until authorities say it is safe.
- Never walk or drive through moving water. Ready.gov notes six inches can knock a person down and one foot can float a vehicle.
- Have power checked before entering if water reached outlets or the panel.
- Wear boots and gloves. Floodwater can carry sewage and chemicals.
Why floodwater is handled differently
Under the S500 standard, water that crosses the ground before entering is the most contaminated category. Porous materials it soaked, such as carpet, pad, insulation and the lower part of drywall, are generally removed and discarded.
Cleanup order
- Document with photos and video.
- Pump out water and remove mud and debris.
- Remove soaked porous materials; cut drywall above the water line.
- Clean and disinfect hard surfaces and framing.
- Dry to normal readings before rebuilding.
Insurance
FloodSmart says most homeowners policies do not cover flood. Flood insurance through the NFIP or private carriers is separate, and Ready.gov notes a new policy typically takes up to 30 days to start. If you have one, report the loss right away.
Local information
San Diego County flood control publishes floodplain information, and the City of Del Mar posts storm updates and resources. Check both before and during storm season.
Returning home after high water
- Wait until officials say it is safe.
- Walk around the outside first for structural damage, downed lines or gas odor. If you smell gas, leave and call SDG&E or 911.
- Have power checked before you turn it on if water reached outlets or the panel.
- Never run a generator indoors or in a garage.
- Wear boots, gloves and eye protection.
- Throw out food that touched floodwater.
The first 48 hours of cleanup
| Task | Notes |
|---|---|
| Document | Photos and video of every room, high-water marks on walls, damaged items |
| Remove water and mud | Pumps for depth; shovels and squeegees for mud |
| Strip wet porous materials | Carpet, pad, insulation, drywall cut above the waterline |
| Clean | Wash framing and hard surfaces; disinfect |
| Dry | Air movers and dehumidifiers; measure until dry |
The EPA says drying wet materials within 24 to 48 hours prevents mold in most cases. After a flood, large volumes and contaminated water make that window tight, which is why many owners bring in professionals early.
Flood insurance specifics
According to FloodSmart, NFIP building coverage for a single-family home goes up to $250,000 and contents coverage up to $100,000. Coverage generally begins 30 days after purchase, with exceptions such as buying in connection with a mortgage. Policies cover the building and its foundation, electrical and plumbing systems, central air, furnaces and water heaters, among other items, while contents coverage protects belongings. If you have a policy, report the flood quickly and keep samples or photos of damaged materials for the adjuster.
Low-lying streets and the lagoon
Homes near the San Dieguito River mouth and the lagoon are the ones most often asked about. Check your address against FEMA flood maps via FloodSmart and San Diego County's floodplain information, and see our low-lying areas page.
What not to do
- Do not push mud or flood debris into storm drains.
- Do not seal walls before they are confirmed dry.
- Do not discard damaged items before documenting them.
Protective gear for flood cleanup
EPA's flood cleanup guidance recommends protecting yourself from mold and contaminated water: wear gloves, goggles and an N95 respirator when working with moldy or flood-soaked materials, and keep children and people with breathing problems away. CDC adds that you should never mix bleach with ammonia or other cleaners. Porous items soaked by floodwater, like mattresses and upholstered furniture, are usually discarded.

Common questions
Is ocean spray or a high tide considered flood?
Coverage questions depend on your policies. Ask your insurer how they classify the water.
Can I clean up myself?
Small, shallow events maybe, with protective gear. Contaminated water over large areas is a job for professionals.
How long after a flood can mold start?
The EPA notes mold can be prevented in most cases if materials are dried within 24 to 48 hours.
What does NFIP cover for a house?
FloodSmart lists building coverage up to $250,000 and contents up to $100,000 for single-family homes.
What should I wear to clean up after a flood?
Waterproof gloves, boots, goggles and an N95 respirator, per EPA and CDC guidance. Keep children and anyone with asthma away from the work.
Is it safe to walk through water in my house?
Not if outlets, cords or appliances are under water. Ready.gov advises not touching wet electrical equipment or anything electrical while standing in water, and turning off power only if it is safe to do so.
