Grand Terrace is a small "East Valley" city, about 3.6 square miles, tucked between Colton, Riverside, and San Bernardino. It incorporated late, in 1978, as the 16th city in the county. It's nicknamed the "Blue Mountain City" for the 2,300-foot peak on its edge. The housing is mostly 1970s-1990s tract construction with some custom homes up on Blue Mountain, so the plumbing is generally mid-age, past the new-build phase but newer than the prewar cities.
Most of Grand Terrace is served by Riverside Highland Water Company. Its water roots run deep: the company dates to 1898, and early settlers drew on local artesian wells. It's hard water, so water heaters collect sediment and fixtures build up scale. Water pressure runs high here, as it does across Southern California, so we recommend testing your pressure regulator every year.

In Grand Terrace specifically, the most common calls we get are for aging copper supply lines (pinhole leaks and repipes) and slab leaks. But the full range of work we do in Grand Terrace includes:
Active leaks, no water, and sewer backups: we dispatch to Grand Terrace 24/7.
Tank, tankless, gas, electric, hybrid. We install, repair, and replace, including code-required earthquake strapping in Grand Terrace.
We find and fix slab leaks in homes across Grand Terrace. We pinpoint them electronically and acoustically, keeping demolition to a minimum.
Licensed gas service for Grand Terrace, home or business. Every line is pressure-tested and leak-checked before we leave.
Grease and root clogs are common in Grand Terrace's 1970s-1990s tract homes. Cable for blockages, hydrojet for grease and roots. Camera inspection on every main line.
Older Grand Terrace homes with aging original copper tend to need a full repipe once pinhole leaks start. We replace with PEX or copper, phase the job and patch any drywall we open.
We work on cast-iron, clay, ABS and PVC sewer lines in Grand Terrace. Trenchless pipe bursting and pipe lining when the line allows, which can save the yard and the driveway.

The company was responsive and professional. Jerry, their representative showed up on time, gave us a detailed quote and installation. I would recommend this company and this tech to others needing a water heater installed.
Matthew Perez did a good job accessing the potential problems. He snaked the drain, removed my 50 year old toilet and installed a new toilet, supply line and 1/4 angle stop. The work was accomplished professionally and to my satisfaction
