Expert Major Plumbing in Glendora, CA

Major plumbing work covers the repairs and replacements that go beyond a simple fix. Think whole-home repiping, sewer line repair, slab leak repair, water line replacement, and burst pipe repair. These are the jobs where getting it right the first time protects your home from water damage, mold, and structural problems. Glendora homes span several building eras. Older properties near the Village area carry galvanized steel supply lines and clay sewer laterals that have been corroding for decades. Mid-century tract homes in central and south Glendora have cast iron drain stacks and galvanized supply lines that are well past their designed service life. Foothill properties face added pressure from elevated water zones and soil movement tied to the area's clay and adobe ground. Owner Jeremy brings 20 years of plumbing experience and a straightforward, honest approach to every job. Whether you are dealing with rust-colored water, a slab leak, a sewer backup, or failing pipes throughout your home, Plumbing Buddies serves Glendora, San Dimas, Covina, West Covina, La Verne, Pasadena, Upland, Claremont, Rancho Cucamonga, Monrovia, and Arcadia.

Major Plumbing FAQ

Common questions about major plumbing in Glendora, CA.

If your Glendora home has rust-colored water, weak pressure at multiple fixtures, or pipes that are original to a pre-1980s build, repiping is likely the right call. Patching a corroded galvanized system usually leads to more leaks in other sections soon after.

Warm spots on your floor, a water bill that keeps climbing, or the sound of running water when everything is off are common signs of a slab leak. Left alone, a slab leak can shift soil under your foundation and cause serious structural damage.

Yes, we handle sewer line repair and full replacement for homeowners in San Dimas. Mature trees in older neighborhoods often send roots into clay or cast iron laterals, and a full line replacement is sometimes the only lasting fix.

Yes, Plumbing Buddies repairs and replaces main water service lines for homeowners in La Verne and Covina. A leaking service line wastes water and can erode soil around your foundation if it goes unaddressed.

Yes, we repair burst pipes for homeowners in Pasadena and Upland. Shutting off your main water valve right away limits damage until we can get the line repaired or replaced.

Hard water in the Glendora area accelerates mineral corrosion inside copper pipes, which leads to pinhole failures over time. When pinholes appear in multiple spots, replacing the affected lines is more reliable than repeated spot repairs.

Ezra and Jose from Plumbing buddies were very professional and respectful of our property and always showed up on time and cleaned up after themselves.Ezra explained what was going to happen once our water got shut off. They began the re-piping under the house with ABS drain lines. finished one day and the 68 year-old cast-iron pipes are now gone. The new black ABS drain pipe should last for a long time. Highly recommend this company.

Recently got a tankless heater installed and Jeremy explained everything in detail. The quote was also fairly priced. The final work looks great. I would highly recommend Plumbing Buddies to anyone looking to repair or replace their water heater. I’ll be using them for yearly maintenance.

I’m writing on behalf of my mom, Nora. Jeremy was excellent to work with from start to finish. He came to my mom’s house to inspect and remove her old water heater and install a new one. Jeremy was professional, punctual, friendly, and communicated clearly throughout the entire process. He took the time to explain everything and made sure all of her questions were answered. She also appreciated how clean and organized he kept his work area from start to finish. The installation was completed efficiently and with great attention to detail. Most importantly, my mom now has the peace of mind that comes with a brand-new water heater and knowing the job was done right. She is very pleased with Jeremy’s service and would highly recommend him to anyone looking for a reliable, knowledgeable, and trustworthy plumber. Do not hesitate to call Jeremy for all your plumbing needs!

They did a great job of replacing the cover for my water heater. It came out great plus after the rain it was making a noise and they came quick to check it out and clean it! They are the best 😊🙏🏼!
