"As a property manager I have doubt was many plumbing companies and I can say I can count on Jess plumbing. He is efficient, reliable and always has fair prices. You can count on him not to overprice because he's honest and knows what he's doing. "

Customers say: Super punctual

"The plumbing technicians came out as promised to assess the leak. They were both very courteous and kind and assessed the damage. I am giving three stars because they estimated the cost to be almost 250% higher than what the actual cost was to fix the issue. I am sure there are customers out there that would just accept any bid however, please get multiple beds for these projects, especially when working with this company as they will inflate the cost to take advantage of the situation. I ended up only paying for the $79 estimate."

"We had a backup in the kitchen sink that needed to be cleared up. Robert assessed the issue, and gave a more than fair quote. He even suggested , if need be, he'd crawl under the house and find the issue. I appreciated the obvious fact Robert wanted to make sure he left with a happy customer. He repaired and we are happy =) 5 STARS !!!!! "

"We did not have a go-to plumber, nor did our neighbors, so we asked Angi. They recommended Steven Bailey, and it was the right choice. The job was a simple replacement of a traditional bathroom sink drain plug with a pop-up that will catch hair and, we hope, prevent future clogs. Steven was responsive, knowledgeable, and friendly, and he explained the options clearly and simply. He is an honest and skilled tradesman, and charged the minimum for the job, which was less than other quotes. Now we have a go-to plumber, and you can too!"

"Though I am happy with the final result, I feel that TJ did a bit of a bait and switch. The person who showed up, Felipe, was from a different company. "TJ" quoted me $900 for the job and $300 to move washer and dryer to access the main valves. That's $1,200. In the end, washer and dryer were not moved. But I did ask them to replace a faucet cartridge in my bathtub, which they did. But before that, Felipe had managed to turn off the water to my unit without moving washer and dryer. He then had to cut into drywall to locate the outbound pipes, but made a mistake. The next cut he made found the water pipes but these were the wrong pipes. An emergency water shutoff to the building was required. In the end, the bill was for $1,800. They did not take credit card. No receipt was given to itemize work done. These guys, from Moor Plumbing Solutions, did work hard and got the job done but there was a serious lack of transparency from the very beginning, not to mention a near disaster."

FAQs for water main install, replace or repair projects in Half Moon Bay, 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.
