The short answer
Not until the power to those circuits is off and you know what the water is. Clean supply water a few inches deep is usually safe to walk through; anything from a sewer line, a storm or a saturated ceiling is not. Call your insurer and a restoration contractor before you start moving things.
When there is water across the floor of your house, the instinct is to start moving things. Before that, three questions decide whether you should be in the building at all — and none of them can be answered by looking at the water.
Risk 1: electrical
This is the one that kills people, and it is the least visible. Water conducts. If it has reached an outlet, an extension cord, a plugged-in appliance, or a recessed light can that is dripping into a pool, the water can be energized.
You cannot tell by looking. There is no shimmer, no sound, no warning.
Do not enter standing water if
- It has reached the level of wall outlets or any electrical device.
- Extension cords or appliance cables are in it.
- Water is dripping from or near a light fixture.
- The electrical panel or a subpanel is in or near the wet area.
- You cannot get to the breaker panel without walking through the water.
If you can safely reach the panel from dry ground, switch off the affected circuits — or the main. If you cannot, stay out and call the fire department. They do this routinely and they would far rather come out than not.
Risk 2: contamination
The second question is what the water is. Restoration classifies it in three categories, and the difference is not cosmetic.
| Category | Where it came from | Can you be in the room? |
|---|---|---|
| Category 1 — clean | A supply line, a bath or sink overflow, rain through an opening | Yes, with basic precautions |
| Category 2 — gray | Washer or dishwasher discharge, a urine-only toilet overflow, sump failure | Briefly, with gloves and boots; keep children and pets out |
| Category 3 — black | Sewage, a toilet overflow with solids, creek or storm floodwater | No. Get everyone out and close the door |
Two things people get wrong here. First, storm water from outside is Category 3, not clean rainwater — it has crossed the ground and paved surfaces and may include sewage if any lateral surcharged upstream. Second, a category escalates with time. Clean water sitting for 48 hours in a warm house is no longer Category 1.
See flood cleanup and sewage cleanup for what proper Category 3 handling involves.
Risk 3: structural
Less common but real, particularly on hillside properties.
- Sagging ceilings holding water above them. They fail suddenly and without warning. Stay out from underneath.
- Saturated hillside soil, which moves. New cracking in a retaining wall or a driveway after a very wet period is a geotechnical question before it is a restoration one.
- Floors that feel soft or springy, which can mean saturated subfloor or, on a raised foundation, compromised support below.
- Gas, if a water heater or appliance has moved or if you smell anything at all. Leave the building and call PG&E from outside.
So — can you stay?
Honest guidance, in the order we would actually give it on the phone:
- Leave now if the water is Category 3, if you cannot safely isolate the electricity, if anything structural is in question, or if you smell gas.
- Leave for the night if a bedroom or the only bathroom is out of service, or if the drying equipment will make the house unusable — air movers and dehumidifiers run continuously and they are genuinely loud.
- Leaving is the right call regardless if anyone in the household is immunocompromised, asthmatic, pregnant, elderly or very young.
- You can probably stay if the water is Category 1, confined to one area, the electricity is safely isolated, and you have a functioning bathroom and bedroom outside the affected zone.
Who to call, in what order
- 911 or the fire department, if there is any electrical risk you cannot isolate, a gas smell, or a structural concern. This is free and it is the right call.
- A restoration contractor, for extraction and drying. This is the time-critical one — every hour the water sits, it spreads. Call us at +1 (201) 277-9344, any hour.
- Your insurance carrier, to open the claim with today's date. You do not need scope or cost.
- A plumber, if a supply line or drain caused it and the source is not already isolated.
Note the order. People often call the insurer first and wait for direction before doing anything else. Your policy does not require that — in fact most policies impose a duty to mitigate, which means acting promptly to limit the damage is your obligation, not a risk to your claim.
What we do when we arrive
Confirm the source is stopped, make the site safe, assess the water category, document everything before it is disturbed, extract, protect contents, and set drying equipment before we leave — never "we will come back tomorrow to set up." Then a written plan with the category, class, initial readings and expected schedule. See 24/7 emergency water removal.
On the Canyon Road corridor and other canyon-bottom properties, one exception overrides everything above: if canyon water is actively rising, leave. Restoration waits.
Frequently asked
Is standing water in a house dangerous?
It can be, in three ways. Electrical is the serious one — water that has reached outlets, cords, appliances or a dripping light fixture can be energized with no visible warning. Contamination matters if the water is Category 3, meaning sewage or anything that came in from outside. And structurally, a sagging ceiling holding water fails without warning, and saturated hillside soil moves.
Who should I call first when my house floods?
The fire department if there is any electrical risk you cannot isolate, a gas smell or a structural concern. Otherwise, a restoration contractor first, because extraction is time-critical and water spreads for every hour it sits — then your insurance carrier to open the claim. Most policies impose a duty to mitigate, so acting promptly protects your claim rather than threatening it.
Will my insurance pay for a hotel?
Usually, through Additional Living Expenses coverage, which is included in most standard California homeowners policies when a covered loss makes the home uninhabitable. It typically covers hotel, meals above your normal spend, and laundry. Ask your adjuster about it in the first call — people routinely stay in unusable houses for days without realizing it was available.
Is rainwater that came into my house clean?
Rain falling directly through an opening in the roof is Category 1. Water that came in at ground level from outside is Category 3, because it has crossed soil and paved surfaces, picking up bacteria, fertilizer and fuel residue, and it may include sewage if any lateral or main surcharged upstream. The distinction matters because Category 3 means porous materials cannot be dried in place.
