"Excellent work completed in less than 24hrs. Wish I?d done my homework for average cost to replace a water heater. $2850 to replace 50 gallon gas water heater seems very steep. "

We are the water heater and sewer experts of Santa Clara County offering free estimates, fair rates, and superior workmanship. Our team has been servicing the Bay Area for over 20 years. Our company is licensed, bonded, and insured. Our specialists are equipped, experienced, and provides a full range of services. We guarantee our work and can beat any quote by 10%.

"Chandlers Plumbing responded to my 'cry for help' during a weekend emergency; and not only showed up on time, with a courteous and knowledgeable crew; they also gave me a VERY reasonable fixed price quote - 75% under those others (that I suspect were price-gauging my "elderly lady in an emergency" status). They were able to start the work right away, and made sure I approved of the work before closing the trench the same day. They left the area like it looked before, with the mulch intact and not mixed up with soil - and my problem is fixed for the next 40 years or so. Definitely recommend ! "

"Rarely write reviews, but I had to take the time to recognize the incredible service I received from Green Arrow Plumbing. From start to finish, this was hands-down one of the best service experiences I’ve ever had! I originally called for a relatively simple job replacing a shower head but while they were here, I also mentioned a persistent issue with my main house drain being clogged. Without hesitation, they jumped into action and took care of both problems quickly, efficiently, and with zero mess left behind. They were punctual, professional, and friendly . They explained everything in simple terms, gave a fair and honest quote, and stuck to it. No upselling, no surprises just quality work done right the first time. If you need a reliable, honest, and highly skilled plumber I highly recommend Cornelio. I’ll definitely be calling them again for any future needs. Thank you for making what could have been a stressful situation completely stress free!"

FAQs for water main install, replace or repair projects in Los Altos, 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.
