From our Las Tunas Drive office, the quickest picture of Rosemead is a straight line. Head south on Rosemead Boulevard, which is also State Route 19, and you reach the city after about 2 miles. That's a rough distance, not a promised arrival time, but it explains why we get so many calls from here.
Water trouble in Rosemead changes with the calendar. This page runs through the seasons, the roads that help dispatch, the landmarks that pin down your address, and what to do the minute water is on your floor.
Rosemead at a glance

Always open
Emergency dispatch available around the clock, in every season and every kind of weather.
Down Rosemead Boulevard, then east or west
Rosemead Boulevard is the spine of the route. Temple City's Soaring Teapot fountain stands at Las Tunas Drive and Rosemead Boulevard, so for us the trip begins at a landmark everyone knows. From there it's a straight run south into Rosemead.
Garvey Avenue is home to The Square shopping center, formerly Diamond Square. If you tell dispatch whether you are east or west of the boulevard and near Garvey Avenue, the conversation gets shorter. Clear directions are the one thing a caller can control.
Whichever company you call, ask whether its crews work to ANSI/IICRC S500, the published standard for water damage restoration, and ask to see moisture readings when the drying is finished.
What each season brings to Rosemead homes
In the rainy months, expect roof leaks, ceiling stains and water coming in under doors. A stain that spreads on a ceiling means water is trapped above it, and a ceiling that sags can drop without warning. Keep people out from under it and call.
In hot months, air conditioner condensate lines clog and drip into ceilings and closets, a source callers often miss until mold shows up. Year round, washer valves, water heaters and pipes under sinks fail without regard to weather. Each of these is a Category 1 clean-water problem when caught early, and gets worse the longer it sits.
The quiet months are a good time to find your main shutoff, check washer hoses and look at the pan under the water heater. None of that replaces a professional, but it shortens a bad night and it costs you an hour.

Close the valve that feeds the leak. If that isn't obvious, shut the main. Then take the small, quick steps: lift valuables, open cabinet doors under a wet sink so air can reach the back, and keep people off wet floors.
Cut breakers for wet rooms only if you can get to the panel on dry floor. Water at an outlet or panel means leave it alone, call the utility or 911 about the electrical risk, then phone us. Edison International, the parent of Southern California Edison, is headquartered in Rosemead, but power problems still go through the utility's own service channels.
Emergency water removal starts with extraction. Portable pumps and truck-mounted units pull standing water, then moisture meters and thermal cameras show where it went. Air movers and LGR dehumidifiers then run until readings fall back toward dry, usually over a few days. That early stage is also what water mitigation means in practice.
Landmarks that help dispatch find you
Rosemead Park has the Rosemead Aquatic Center and a half-mile fitness trail, which makes it a good reference if your street is nearby. Rio Hondo Avenue is where Savannah Elementary School sits, and the historic Savannah area with the Savannah Pioneer Cemetery lies near Valley Boulevard and Mission Drive.
The Whittier Narrows area is on the Montebello border at the city's edge. If you live out that way, flag it on the call, because it's one of the farther corners from the Temple City base. For cleanup after the water is out, see our water damage cleanup page.
ZIP 91770 and the streets around it
Rosemead's ZIP for this page is 91770. Other ZIPs touch the city's edges, and if your mail shows something different, ask us and we'll confirm coverage on the phone instead of guessing. The better guide is the street, whether that's Rosemead Boulevard, Garvey Avenue or Rio Hondo Avenue.
The city borders San Gabriel, Temple City, El Monte, South El Monte, South San Gabriel, Montebello and Monterey Park. Our pages for San Gabriel and El Monte cover the neighboring cities.
Golden State Water and your bill
Part of the city falls inside Golden State Water's San Gabriel area. Some addresses are theirs and some aren't, so the water bill is the answer. If the leak is upstream of your meter, the supplier gets that call, and we come in once the water is stopped.
Before we arrive: what to do while water is still spreading
Stop the flow at its source
Close the nearest shutoff, or the main valve at the meter side of the house.
Switch off only what is safe
Cut power to the wet rooms only if the panel is dry. Otherwise stay clear and call the utility.
Get valuables off the floor
Lift bags, cables, books and boxes first, then pull rugs and small furniture out of the wet zone.
Avoid the standing water
If it came from a drain, toilet or outside, treat it as contaminated and keep everyone out.
Dial our line
We answer (626) 879-0276 every hour of every day.
Rosemead facts worth knowing before you call
Rosemead residents voted to incorporate on August 4, 1959, and 51,185 people lived here in 2020. The city covers about 5.17 square miles at about 318 feet of elevation, lower than Temple City's roughly 400 feet. Lower ground can mean water sits longer, so raise drainage with the city or LA County Public Works if your street has repeated trouble.
The Savannah area is the city's historic corner. If your home is there, mention it, because the age of a building can change what a crew expects to find behind a wall. We don't assume ages, so we ask.

Frequently asked questions
This page covers ZIP 91770, the Rosemead ZIP we serve, from Rosemead Boulevard out to Rio Hondo Avenue and Garvey Avenue. If your address uses a neighboring ZIP, call and ask. We'll confirm coverage on the phone instead of guessing.
Yes. The line is staffed 24/7, and the Rosemead Boulevard route runs straight south from our base. We can't promise arrival times, but you'll get first steps on the call itself.
Roof leaks and water coming under doors are common in rainy months. Ceiling stains mean water is trapped above, and a sagging ceiling can fall. Keep people clear and call so crews can open it safely.
A clogged condensate line can drip into a ceiling, closet or wall for days before anyone notices. That slow water is exactly how mold gets started. The EPA advises drying damp materials inside 24 to 48 hours to head off mold, so earlier is better.
Portions of Rosemead sit in Golden State Water's San Gabriel service area, but not every address does. Your bill shows who serves your home.
Yes. If water has reached outlets or the panel, we ask you to stay out and call the utility or 911 first. Crews won't work around live hazards, so that call comes before ours.
