Across the Rio Hondo, on the west side
Montebello lies west of Pico Rivera, about 4 miles from our base on Whittier Blvd, and the Rio Hondo marks the line between the two cities. Because we start on the Pico Rivera side of that river, a Montebello address is a short trip and not a cross-county haul.
That matters on a bad night. A kitchen line that stops draining at 11 p.m. or a water heater that starts leaking onto a garage floor needs someone who is already close, and the 24/7 dispatch line routes those calls straight to a crew. When the water reaches the Santa Fe Springs or Norwalk side of our map, the same crew logic applies, as you can see on our Santa Fe Springs page and our Norwalk page.
The main Montebello ZIP is 90640. The nearby 90022 area on the East Los Angeles side sits along Montebello's western border, and we take calls from it as well. If you are unsure which side of the line your street falls on, give dispatch the street address and they will confirm.
Montebello overview for plumbing calls
Four facts we plan around when a Montebello number rings.
Emergency dispatch around the clock
Active leaks, sewage backups and failed heaters are answered at any hour, including weekends and holidays. Call the dispatch line and say what is happening before you say anything else.
61,045 residents
That is a large population for one city, so older streets of single-family homes share space with apartments and mixed-use buildings. Ask us which fixtures are on a shared line before you assume a clog belongs to your unit alone.
Median home built in 1963
The middle of the housing stock is more than 60 years old, which puts original supply lines and cast iron drains at the age where wear shows up. A repair visit is a good moment to ask what else in the same wall looks tired.
Two ZIPs, one west border
Calls tagged 90640 are Montebello proper. Calls from the 90022 area on the East Los Angeles side get the same dispatch line and the same pricing method.
For a Montebello kitchen or bath that keeps backing up, Drain Cleaning is usually the first stop, and it can be booked the same day when a slot is open.
Water on the floor in Montebello?
Shut the main valve, then ring dispatch. We send a crew from the Pico Rivera side of the river and quote the price before work starts.
Montebello home age and the repair it tends to bring
The Census American Community Survey for 2024 counts 20,386 housing units in Montebello, and 84.1 percent of them (17,141 units) were built before 1980. Use the table to match your house to the likely problem.
| When it was built | What tends to wear out | Where to read more |
|---|---|---|
| Before 1960 | Original galvanized or early copper supply, cast iron drains | Repiping |
| 1960 to 1979 | Aging water heaters, corroded shutoffs, slow main drains | Water Heater Replacement |
| 1980 and later | Fixtures, disposals, supply connectors | Drain Cleaning |
| Any year | Sudden pipe failure in a wall or ceiling | Burst Pipe Repair |
Counts are from the Census ACS 2024 5-year estimate. Your own house can differ from the city average.
Montebello water: ask your utility, test your tap
We could not confirm which utility bills each Montebello address, and we have no hardness figure we trust for the city. So we will not guess at it here.
Ask your water utility for its annual water quality report, then test your tap or get a simple hardness kit. If the number is high, scale on a tank heater is a real possibility, and that changes how long a replacement is likely to last and whether a softener is worth adding. Bring the result when you call (562) 488-9614 and we will factor it into the quote.
Before we arrive: a burst pipe or active leak in a Montebello home
Do these four things while the crew is on the way.
Shut the main valve
Turn it clockwise until it stops. In many older Montebello homes it sits near the front hose bib or by the garage wall, so look there first.
Kill power near the water
If water is near outlets, a panel or appliances, switch off that breaker. Do not step into standing water to reach it.
Clear the area
Lift rugs, electronics and anything cardboard off the floor. Move children and pets to a dry room.
Call the 24/7 line
Ring (562) 488-9614 and tell dispatch where the water is coming from. They will pass the notes to the crew heading your way.
What to have ready when you call from Montebello
A few details speed up an after-hours visit.
- Your street address and nearest cross street.
- Which fixture or room is affected.
- Whether the main valve is shut.
- Whether the home is a house, a unit or a shared building.
- Any hardness number from your utility report.
If the problem is a sewer line that backs up more than one fixture, mention it first, because a main line and a single drain call need different tools.
Standards and sources behind this page
Housing figures on this page come from the Census Bureau's American Community Survey. We did not find a published water provider or hardness figure for Montebello, so we point you to your own utility's report.
Questions we hear most
We cover 90640, which is Montebello itself, and we also take calls from the nearby 90022 area on the East Los Angeles side, along Montebello's western border. That 90022 area is not a Montebello ZIP, so confirm your street with dispatch at (562) 488-9614.
Both are reached from our Whittier Blvd base across the Rio Hondo.
Yes. Dispatch runs around the clock, every day, and Montebello calls get the same priority as any other. Say whether water is actively flowing, a drain is backed up or gas is involved.
If you smell natural gas, leave the home and call SoCalGas at 1-800-427-2200 from outside before you phone us.
We could not confirm that for every address, so ask your water utility directly and read its annual water quality report. Test your tap if you are weighing a softener or a new heater.
Not automatically. Median construction year here is 1963, and many homes that age still have working lines. A camera or pressure check shows more than the date does, and Repiping only makes sense if repeat leaks show up.
Yes, but tell us up front that the line is shared. We may need building access, and the fix could involve a neighbor's unit or the property manager.
Look near the front hose bib, along the garage wall or by the water heater, then turn the valve clockwise. If it will not move, stop forcing it and ring (562) 488-9614.
Yes. A leaking tank is an emergency because it can soak a floor quickly. Shut the cold supply to the heater and call, and we will talk through repair versus replacement on the phone.
