"Gustavo from Escamilla Plumbing responded quickly to my call for help in determining whether to repair the existing toilet. I reviewed our history of the 14 year old Toto and our current problem with the small amount of water left after flushing. He adjusted the fill valve and made adjustments to shower valve and sink faucet. Gustavo listened attentively to my existing problems and was very professional in determining his actions and I plan to use his services again."

"When a pipe burst in our garage, we were pretty stressed trying to figure out what to do. Ron came out right away, shut everything off, and replaced the section of pipe that broke. He worked quickly but also took the time to explain what had happened and how to avoid it in the future. Really grateful for how calm and professional he was in a stressful situation. "

"I had a backup in my main sewer pipe and Jess Plumbing came out and did a thorough inspection, he then found that my main sewer pipe was incorrectly installed by the previous installer. To make a long story short, this guy knows what he is doing, has the equipment including cameras and an excellent team. They did an AMAZING job at a FAIR price. Replacing the main sewer pipe is no easy job, but they were able to do it and do it right. They also cleaned everything up at the end of the day and even planted back the plants that had to be removed during the process!"

"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. "

"We needed our Garbage Disposal replaced. We bought one, but realized we needed help to get it installed. Mike Counsil to the rescue. This is the 3rd time we have had work done by them. Last year they redid the pipes in our house, so it was a no brainer to call them for help with disposal installation! They communicate during the entire thing. Called and showed up when they said they would. This time we had Besmir and Jordy doing the work. Very friendly, explained what they needed to do, made suggestions along the way. Cleaned up afterwards. Great experience overall!"

"My first time to use their services. They are very professional and knowledgeable in their field. Shane notified me when he will arrive. He was on time and very professional. My existing water softener needs to be replaced. He advised me to get a different system that would be more suitable for my situation. I will definitely hire them to install the new water softener system installed."

"Guy who came gave me good advice and advised that he felt my issue was not needed for repair. He didn't try to sale me any service as he saw no need. I appreciate a plumber who isn't trying to get work out of people whom don't need it."

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