If you are a homeowner or business owner in Claremont, we would be glad to help and to treat your home or business like our own. We answer the phone 24/7 at (909) 312-4516. Claremont has one of the largest shares of historic homes of any city we serve. The Village and the residential streets around the Colleges have Craftsman and Spanish Revival homes from the early 1900s to the 1930s, and their mature trees mean serious root intrusion in clay sewer laterals. We do a lot of careful, preservation-friendly repipes here: homeowners value keeping the original wall finishes, and crawlspace access matters. North Claremont is a different story: custom 1960s-1980s homes where standard repairs are the usual calls.

What we see in each part of Claremont:
Craftsman and Spanish Revival from the early 1900s to the 1930s. Repipes here are preservation work.
1960s-1980s custom hillside homes. Mostly standard repair work.
Early 1900s to 1930s homes surrounded by mature trees. Root intrusion in clay sewer laterals is a recurring issue.
Mix of mid-century and newer infill. Mostly standard repair and water heater service.
Claremont grew up around The Claremont Colleges (Pomona College moved here in 1889) and incorporated in 1907, and its tree-lined streets and colleges earned it the nickname "City of Trees and PhDs." The Village and the streets around the Colleges hold Craftsman and Spanish Revival homes from the early 1900s to the 1930s: beautiful, and full of decades-old plumbing. North Claremont rises into the San Gabriel foothills with 1960s-1980s custom builds. The mature trees that make the city gorgeous are also why we pull so many roots out of sewer laterals here.
Claremont is served by Golden State Water Company, a private utility with a 24/7 customer line (1-800-999-4033). Its water is a blend of local groundwater and imported State Water Project water, and it's hard (about 11 grains per gallon), so we see plenty of sediment in tank heaters and scale on valves. Like the rest of Southern California, Claremont gets strong incoming water pressure, so we recommend testing your pressure regulator every year.

In Claremont specifically, the most common calls we get are for historic-home plumbing and mature-tree root intrusion. Many homes in the Village and the streets around the Colleges have original plumbing that needs careful, preservation-friendly repiping, and the big trees along College Avenue, Indian Hill Boulevard and the residential streets near the Colleges send roots into old sewer laterals. But the full range of work we do in Claremont includes:
Active leaks, no water, and sewer backups: we dispatch to Claremont 24/7.
Tank, tankless, gas, electric, hybrid. Claremont's older homes often need code-update work around the unit during replacement.
Slab leak detection for Claremont homes built on a slab. We locate slab leaks with electronic and acoustic tools, then repair with minimal tear-out.
We handle natural gas lines for Claremont properties of all kinds, with pressure testing and leak checks on every job.
In Claremont's older homes, the sewer laterals are often cast iron or clay, with root intrusion. Camera inspection on every main line, then cable for blockages or hydrojet to clear roots and grease when the pipe is sound.
In Claremont's older housing stock, failing galvanized supply lines are a regular issue. We repipe with PEX or copper, work in stages, and protect your walls and original finishes.
Original clay laterals are common in older Claremont neighborhoods: when they crack or roots get in, we line them in place or replace them. We work on cast-iron, clay, ABS and PVC lines, trenchless when possible.
Annual testing & certification for Golden State Water Company requirements. We file the paperwork directly with the water company on your behalf. We also install and repair backflow preventers.
From restaurants to retail to multi-unit and office buildings in Claremont, we offer flexible, after-hours scheduling.
Sweetwater Plumbing's service area extends across San Bernardino, Riverside and eastern Los Angeles counties.
