Roughly 13 miles southeast of downtown Los Angeles, Downey sits low on the coastal plain at about 118 feet, part of the Gateway Cities. Concrete flood channels carry the rivers past town today, but a semi-arid climate with sudden winter storms still tests roofs, drains and plumbing.
Fire & Water Energy operates purely as a referral connection to independent restoration companies; it has no crews of its own. When you ring (866) 937-3230, we try to match you with a contractor covering Downey, though openings depend on who is taking jobs. Anyone curious about the fine print can browse our how it works and disclosure pages before calling.
The Old River, concrete channels and quake history
Downey's early ranch land lay between the Rio Hondo and the San Gabriel River. According to Wikipedia, a flood in 1867 shifted the San Gabriel's course, and the abandoned channel near Downey came to be called the Old River before taking the Rio Hondo name. Most of the Rio Hondo is now lined with concrete for flood control and joins the Los Angeles River in South Gate.
Ground shaking is part of the picture too: the 1994 Northridge earthquake damaged the 1953 Speedee McDonald's at Florence Avenue and Lakewood Boulevard. Los Angeles County has been named in 14 FEMA major disaster declarations since 2000, including severe winter storm declarations in 2017, 2023 and 2024.
Why older Downey houses spring leaks
After World War II, suburban tracts replaced the farms here, so a large share of houses are many decades old. Original galvanized or copper lines, slab plumbing, aging water heaters and washing machine hoses are frequent sources of hidden water. Winter rain finds worn shingles and flashing, and condensate lines from air conditioners can overflow quietly during hot spells.
For water damage restoration in Downey, contractors commonly locate the source, test moisture in walls and floors, remove soaked carpet pad or drywall, and run dehumidifiers. If a supply line broke, see burst pipe water damage.
Federal disaster declarations that included Los Angeles County
FEMA records show Los Angeles County was included in 14 major disaster declarations for weather or fire events from 2000 through 2026 (7 fire, 5 severe storm, 2 flood, by FEMA incident type). Declarations are made at the county level, so they do not mean every neighborhood in Downey was affected. The most recent:
- 2025 – Wildfires and Straight-line Winds (DR-4856)
- 2024 – Severe Winter Storms, Tornadoes, Flooding, Landslides, and Mudslides (DR-4769)
- 2023 – Severe Winter Storms, Straight-line Winds, Flooding, Landslides, and Mudslides (DR-4699)

- 2020 – Wildfires (DR-4569)
- 2018 – Wildfires (DR-4407)

Soot, smoke odor and the basin's fire seasons
County wildfire declarations in 2018, 2020 and 2025 brought smoky days to communities far from the burn areas, Downey included. Fine ash settles on window sills and patio furniture and can be pulled indoors through HVAC returns.
A house or garage fire leaves heavier residue. Fire damage cleanup usually begins with debris removal and protecting undamaged rooms, then moves to soot removal and deodorizing. Ask whether the contractor will clean ductwork, since odor often lingers there.
Heavy rain, ponding streets and storm debris
Flood channels handle the big rivers, but intense bursts of rain can still overwhelm neighborhood storm drains and push water into garages, sunken patios and ground-floor rooms. The county's Ready LA County site keeps rain and flooding guidance worth reviewing each fall.
Outdoor water carries street runoff and possibly sewage, so porous items it soaks are usually discarded. Flood cleanup involves extraction, removing wet materials, sanitizing and drying. Downed trees and wind-torn roofs belong under storm damage cleanup.
Spotting and handling mold
Even in a dry climate, mold grows wherever moisture stays put: under sinks, behind a leaking dishwasher or in a wall cavity after a roof leak. Musty smells and staining near baseboards are early clues.
The EPA says areas under roughly 10 square feet can often be cleaned by a homeowner wearing gloves, goggles and an N95. Larger patches, or mold that follows floodwater, call for professional mold remediation with containment and HEPA filtration.
Protecting yourself and your claim in Downey
- For flames, smoke inside, a gas smell or injuries, get out and dial 911.
- Do not wade into a flooded room while the power is on.
- Sign up for Alert LA County on Ready LA County before the rainy and fire seasons.
- Shoot photos and video before cleanup begins and keep every receipt. Coverage depends on your policy; your insurer or agent can tell you what documentation they expect.

Downey restoration FAQs
Does the Rio Hondo or San Gabriel River flood Downey?
Both rivers near Downey run in engineered flood control channels, with the Rio Hondo largely concrete-lined. Day-to-day storm problems are more often local drains backing up during intense rain. Check Ready LA County flooding guidance for current advice.
My Downey home was built after World War II. What should I check?
Many houses from that era have original plumbing that may be corroded, plus older roof layers and water heaters. A plumber or inspector can look for slow leaks before they cause rot or mold. Replacing rubber washer hoses with braided lines is a simple step.
Can earthquakes cause water damage?
Yes. Shaking can crack pipes, break water heater connections and damage roofs, as the 1994 Northridge earthquake did to buildings in Downey. Strapping your water heater and knowing where your main shutoff is helps.
Is wildfire smoke a concern even though Downey is not near the hills?
Smoke from large Los Angeles County fires can travel across the basin and settle into homes. Keep windows closed on smoky days and change HVAC filters afterward. Heavy residue may need professional cleaning.
Does Fire & Water Energy send its own workers to Downey?
No. We are a referral service that tries to link you with an independent contractor serving the area, and that business quotes and performs the work.
