"Leo did a very extensive plumbing repair that required digging through my bathroom floor and replacing a huge pipe to the outside. He also prepared and installed piping and fixtures for a bathroom remodel. Always showed up when he said he would and had a great crew. Cleaned up as well. Would highly recommend. "

"Can not imagine a better response, starting with my call for assistance, response time and how the technician, Tad methodically diagnosed the problem. We have an obscure kitchen fixture that required service in Feb 2019. Under warranty the problem was easily diagnosed by me, a problem possibly caused by me and a replacement part sent and installed by Albert Nahman team. Problem: I broke the faucet cartridge. Current Problem: restricted hot water flow in this kitchen sink only. Turns out the new cartridge part is now malfunctioning. I called and Tad arrived taking a step by step approach ruling out possible causes: a clog here or there, build up of sediment, or blockage in the lines or cartridge. The company that sells the product got on the phone with Tad and they collaborated on the problem and the tech person gave Tad one more thing to try. After the collaboration it is agreed, problem persisted and therefore that new cartridge part is now malfunctioning and will be shipped free of charge in two days. Thanks to all, who made this possible and I trust we will have Tad here again soon to finalize this fix. BTW, cost of service was less than expected given going rates for such a call lasting in excess of one hour. Another comment, spending time with Tad during the repair was a pleasure to have him explain, collaborate, listen and just chat. Questions on who to call next time, no question who I will call next time. I have read criticism of costs: In the Berkeley area "How much does it cost to hire a plumber? Some plumbers have a minimum fee for a service call. They might charge anywhere from $175-250 to come out and give you a consultation. Plumbers may give you a general service rate of $128-148 per hour when there are a lot of unknowns about a project and they aren't sure how long it will take. Some charge a flat rate for their plumbing services. For example, you may get charged $175 for a sink or drain cleaning, while toilet installation costs $500." Today costs are upfront, same as charges in Feb, $69 to arrive and assess the problem. Here in excess of one hour for $129 minus $25 coupon, total charge $173. I am ok and I expected these costs. If I was in Philly, where I grew up, I could call an uncle or cousin and get a better rate, a family rate. This is going rate for our area."

"Fito Plumbers installed a new sewer line at my house. I appreciate good customer service when I see it, especially when it is with a contractor. My experience with Fito Plumbers was a positive one from the very beginning. From the quote, all the way through the final signoff Fito's team was great. Fito was honest and kept in communication with me over the one month period that it took to get the permits. His team showed up when he said they would, they were courteous and they respected my property. They did not kill one plant on my property which is a first. They cleaned up at the end of each day and they restored the pavers to the point where I can not tell where they had to remove them. I also appreciate that Fito's team power washed all the utility paint markings not only on my property but in the street. My street is covered with paint from previous work by others. Overall, Fito Plumbers was competitively priced and went beyond expectations with the installation."

"Never had such a great experience with any contractor. So grateful to Eugene, Artem, Nick, and Alex not only for the great work they did, but for the care and attention they put in for 3 straight months. My house is built kind of complicatedly and the water heater isn't located in the most accessible place, but they were able to make it work. Not only that, but Eugene found me a new tankless water heater that would also work with my radiant floors - not only saving cost, but space as well. To say they went above and beyond is an understatement. They came back multiple times to make sure work was up to par - never half-assing anything. Really hoping I don't have any reason to need to reach out again soon, but if I do, I know who I'll be calling. Also, special shout out to Jeremy, Karen, and Kathy for their logistical help as well!"

"Ishmael was eager for my business and came out right away to assess and provide a VERY competitive bid for the job. After agreeing on the work, price, and date his team showed up on time and did a great job with replacing my main water pipe from the street to the house. After completion they made sure my landscaping was as back to normal as possible and I did not have to do any extra cleanup. Fantastic service. Would highly recommend."

FAQs for water main install, replace or repair projects in Castro Valley, 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.
