Above all, we are watchful of our customers' interests and make their concerns the basis of our business. Our customer's safety is extremely important, which is why all of our technicians are fully trained, background checked, and drug tested.

"A troublesome shower drain was resolved quickly by Oak Plumbing. I want to recognize Niles, Harris, Jessy, and Amari for their great work. Niles inspected the crawlspace, measured every line, and gave me a fair quote based on my home’s actual layout. Harris cleared space for the new pipes, sketched the floor plan, and confirmed materials. Jessy and Amari replaced all horizontal drain lines—including the garage sink, washer, kitchen sink, two toilets, shower, and two sinks—in tough conditions under the house. This started after another company gave me a flat-fee quote based on “two bathrooms.” Oak Plumbing’s quote was more detailed and more accurate for my 1950s home with 1.5 baths and mixed old materials. Their bid was over 10% better, and I left a deposit that day. I’m grateful for how quickly they solved the problem, especially days before Thanksgiving. As a single mother who relies on Angie’s List, this experience fully met expectations. I highly recommend Oak Plumbing."

FAQs for water main install, replace or repair projects in Walnut Creek, CA

If you notice puddles or standing water in your yard, a sudden drop in water pressure, cracks forming in your foundation, frequent clogs in your plumbing fixtures, or water that looks or smells unusual, you might have a leak in your main water line. These signs mean it's time to call a professional to evaluate the issue and prevent further damage.

A professional water main inspection is a comprehensive evaluation performed by a licensed plumber who checks every section of your plumbing system. The inspection costs $165 and uses advanced diagnostic techniques to identify hidden leaks or wear. This service clarifies the exact condition of your water main, enabling precise repairs that prevent future damage and ensure the overall health of your plumbing system.

Protect your water main by scheduling a cleaning and inspection every two to five years. The average cost of a sewer line cleaning is $400. It’s also important to never dig in your yard without first calling the dig line (811) to ensure you don't accidentally hit the water or sewer lines. Watch for soil erosion, low water pressure, or wet spots in your yard, and take immediate action if you suspect a leak. Remember, the longer you leave it, the worse the problem gets and the more costly it is to fix.

When properly maintained, your water main is engineered to remain functional for 50 years or longer. A durable water service in excellent condition should consistently perform without major issues for half a century. In contrast, metal pipes exposed to acidic soil corrode faster, whereas modern plastic pipes resist corrosion and function for decades beyond metal alternatives. Regular maintenance and inspections are essential for confirming your system’s longevity.

No, homeowners insurance does not cover the cost to repair a water main. Insurers fund only sudden, unforeseen events like a burst pipe and exclude gradual issues or normal wear and tear. Damage resulting from leaks, such as mold remediation or property claims, is not covered. It is essential to contact your insurance provider immediately to confirm your policy’s details and any potential adjustments needed.
