Grand Terrace sits roughly 3 to 4 miles northwest of Loma Linda, and Loma Linda Water Damage Pros runs 24/7 emergency dispatch for homes here. Call at night, on a weekend or on a holiday, describe what is wet, and dispatch walks you through the first steps while a crew is sent.
The Blue Mountain City is small, about 13,150 residents in 3.5 square miles, incorporated in 1978. Even so, it has several kinds of ground, and they change what water does once it gets loose.
Around Blue Mountain, Barton Road and Mount Vernon Avenue
The Blue Mountain hillside rises past 2,300 feet, and homes on the slopes below it sit downhill from a lot of bare ground. In a hard rain, runoff finds the low side of a lot. If your garage slab, side yard or patio drains toward the house, clear gutters and downspouts before storm season and call us when water crosses a threshold.
Along Barton Road and Mount Vernon Avenue the housing is mostly single family, and Interstate 215 runs through the city. Veterans Freedom Park, Richard Rollins Community Park and Grand Terrace High School are easy landmarks when you are rattled. The old Gage Canal once carried water here, so if a corner of your yard stays soggy, mention it on the call.
When water is spreading in Grand Terrace
Water keeps moving into materials long after the puddle looks small. Stop the source if you can, close the main water valve, lift valuables off the floor and keep people and pets out of water that may be contaminated. Turn off power to wet areas only if the panel is dry and reachable. If water has reached outlets, the panel or a gas appliance, call the utility or 911 before you call us.
Find your shutoff
Turn the main valve clockwise until it stops. If it will not move, say so on the call.
Photograph first
Take wide shots and close-ups of wet walls, floors and belongings. They help when you talk with your insurer.
Lift what you can
Move rugs, books and electronics to a dry room, and get couch legs off wet floors.
Name the source
Tell dispatch if it was a supply line, water heater, hose bib, roof or drain. Sewage needs different handling than clean supply water.
Three agencies, three different phone calls
Water comes from Riverside Highland Water Company, not the city and not Colton. A leak at the meter is theirs to sort out, while a break on your side of it is yours and a plumber's. Sewer is split again: the city owns the lines, Colton operates them, and Burrtec bills residential sewer customers.
So a backup in the street main is a different office than the one that sells you water. Confirm with each agency which one handles your problem, then call a restoration crew for whatever got wet inside the house.
Older plumbing in a city built mostly before 1990
The General Plan says 36 percent of housing units were built before 1970 and over half from 1970 to 1990. Many supply lines, water heaters and hose bibs from that era are at or past typical service life, and a bulging washer hose can flood a laundry room at 2 a.m.
Water mitigation comes first: extraction, air movers, LGR dehumidifiers, and moisture meters and thermal imaging cameras to find wet wall cavities. Water damage repair follows once readings show the structure is dry.
Water on the floor right now?
Dispatch answers at night and on weekends. Call 24/7 and tell us what is wet.
Call (909) 505-3870Floodplain land and what to check for your address
The General Plan flags industrial land in the Santa Ana River floodplain for potential severe flooding. For a home, check the FEMA flood map for your address, and ask your insurer, because flood is usually excluded from standard homeowners policies. Storm or river water is grossly contaminated, so see flood damage restoration and, after drying, water damage cleanup.
Drying, cost and codes
A crew checks safety, identifies the water category, extracts standing water and maps moisture. Drying usually takes three to five days, longer for hardwood or plaster, and crews work to ANSI/IICRC S500. Cost depends on category, area, materials and drying days, so ask for your real number by calling dispatch and check your policy.
Building and Safety at City Hall, 22795 Barton Road, has adopted the 2025 California codes. Ask whether your plumbing or water heater repair needs a permit.
ZIP coverage
Our crews cover 92313, the city's own ZIP, for water damage repair, water mitigation and emergency water removal. Some addresses use the Colton ZIP for mail, but it is Colton's own, so see Colton coverage. Homes in Redlands reach the same dispatch.
Grand Terrace water damage questions
Do you cover every ZIP code in Grand Terrace?
Yes. The city's own ZIP is 92313, and that is the one we list for Grand Terrace.
Some addresses use Colton's ZIP for mail routing. That ZIP is Colton's own, so give dispatch your street address and we will confirm coverage.
Is emergency water removal available in Grand Terrace?
Yes. Dispatch is open 24/7, including nights, weekends and holidays. Call, describe the source, and extraction starts as soon as a crew is sent.
Who do I call for a leak, the city, Colton or the water company?
A leak at the meter starts with Riverside Highland Water Company. The city owns the sewer lines, Colton operates them and Burrtec bills sewer customers. Confirm with each office.
Does hillside runoff cause water damage near Blue Mountain?
It can. Homes below the hillside may see runoff cross a lot in heavy rain. Keep gutters clear, and call us if water reaches the slab.
Are older plumbing parts a common cause of leaks here?
Many homes were built before 1990, so supply lines and water heaters are often old. Replace worn parts before they fail.
Will my homeowners policy cover this?
Sudden and accidental damage is often covered, gradual leaks often are not, and flood is usually excluded. Check your policy, keep receipts and ask your insurer before permanent repairs.
