Storm safety: power, standing water and the first hour
Storms bring two hazards at once, water and electricity. If water is near outlets, the panel or a power strip, stay out of that room. Leave the panel alone if the floor around it is wet, and call the utility or 911 about downed lines, sparks or any gas smell.
Water that rises from outside, or looks muddy or smells of sewage, may be contaminated. Keep children and pets out of it and do not wade through it.
- Stay out of rooms where water touches outlets or the panel
- Never run a generator indoors or in an attached garage
- Keep people and pets out of water that came from outside
- Photograph water lines and damage from a dry spot
How rain finds its way in when the wind is behind it
Wind-driven rain moves sideways, so it gets past places that stay dry in a straight downpour. Loose flashing, worn window seals, cracked stucco and gaps under doors let it through. Clogged gutters send roof water down walls instead of away, and soil that slopes toward the foundation pushes it against the house.
Weather service totals for downtown Los Angeles show how hard one storm can hit. The storm of February 4 to 6, 2024 dropped about 8.51 inches, the second-wettest three-day span on record there. February 4 alone was the wettest day since March 2003, at about 4.1 inches.
The long-term annual rainfall there is only about 14.25 inches, so more than half of a normal year can land in a few days. Clear gutters and downspouts in autumn and check window seals before the wet season starts.
From soaked walls to dry framing: the work after the rain
Crews start by finding where the water went. Moisture meters and a thermal imaging camera show wet drywall, baseboards and flooring that look fine on the surface. Standing water comes out with extraction units and weighted extractors. Wet carpet pad, soaked insulation and swollen baseboard are removed so they stop holding water.
Air movers and LGR or desiccant dehumidifiers then dry the building. Where walls were wet, crews may open small sections or pull baseboards to reach the cavity. Work follows ANSI/IICRC S500 practice, with readings logged at each visit until the structure is dry.
Signs that rain got in, including the ones you cannot see
Some storm damage is obvious, like a soaked carpet. Some hides behind paint and under flooring for days. For ceiling stains that come from the roof itself, see roof leak water damage.
| Sign | Likely route | What it means for drying |
|---|---|---|
| Wet carpet along an exterior wall | Window, door or foundation seepage | Pad may be soaked, so check the wall base |
| Stained ceiling after wind and rain | Flashing or vent gap | Insulation above may be wet |
| Bubbled paint near a window | Failed seal or sill | Moisture may run down inside the wall |
| Water at a wall base after a downpour | Yard slope or clogged drain | Muddy water changes how it is handled |
Rain damage or flood damage?
The difference decides the handling. Rain that enters through a roof, window or wall is generally cleaner than water that rises over the ground and into the house. Water that comes up from a drain, or flows in carrying soil, is treated as contaminated and brings stricter steps. If that is what you have, read about flood damage restoration.
Insurance: rain through the roof, water over the ground
Insurers often separate storm water that enters through a damaged roof, window or wall from flood water that rises from the ground. Policies often cover sudden rain damage through the building but treat rising flood water as a separate, excluded cause. Check your policy and ask your insurer which category your loss falls in.
What shapes the size of a storm water job
Scope follows the number of rooms wet, how deep the water was, whether it came from outside and how much carpet, pad and insulation must be removed. Access matters too, since a wall that must be opened takes longer than a surface that can be dried in place.
Water came in with the storm?
Call the 24/7 line and say where it entered.
Mistakes people make after a storm
Waiting for the rain to stop before calling is common, yet wet materials start holding water at once. Stacking towels along a wall and calling it done is another, since water is often behind the baseboard. Running a household vacuum on wet carpet is risky, and so is walking into a flooded garage to rescue boxes.
Fix the entry point as soon as the weather allows. A roofer or window contractor handles the opening, and the crew handles what it soaked. If dark growth appears later, that falls under mold remediation.
Storm water in Montebello: streets, the river and the city's hazard plan
A Safe Clean Water Los Angeles planning document for a City of Montebello stormwater capture project names known flooding on Lincoln Avenue between Avenida De La Merced and San Gabriel Boulevard. It also lists candidate sites near Rio Hondo, Grant Rea Park and Olympic Boulevard. Street flooding is a stormwater issue, but water that enters a building is a damage issue, so photograph it and call.
The City of Montebello 2025 Local Hazard Mitigation Plan, posted on its emergency management page, evaluates hazards including flooding, high winds and power outages. Those are the same conditions that push rain into buildings and stop pumps. Read it, then find your main water valve and electrical panel before the next storm.
Rio Hondo runs along the east side of the city next to Pico Rivera, and Monterey Park lies to the north.
Storm water damage questions answered
Is emergency storm water damage cleanup available in Montebello?
Yes. The line is answered 24/7, including nights, weekends and holidays, and that includes storm nights. A crew is sent the same day when one is available. No arrival time is promised, so describe where the water is and keep clear of outlets.
Does your crew fix leaking windows or flashing?
No. Windows, flashing and gutters belong to the right contractor. Our crew extracts the water, removes materials that cannot be saved and dries the structure after the opening is closed.
What if the water came up from a drain or over the ground?
Say so on the call. Water from outside or from drains is handled with stricter steps than clean rain water, and porous materials often cannot be saved. Keep people and pets out of it until a crew has looked.
How soon should drying start after a storm?
As soon as the source is closed. Wet wall bases left for more than two days after a storm are where mold usually shows up first.
What should a Montebello homeowner check before the next storm?
Clear gutters and downspouts, look at window seals and door thresholds, and see that soil slopes away from the walls. Find your main water valve and panel, and take dated photos of the house now so you have a baseline.
