Sergio and Joseph were out to my house in about a half hour after calling and this was on a Saturday. I had a leak in the main water supply just after the water meter so the repair was my responsibility. They had to remove the concrete meter cover and dig to clear and clean the pipe. They had the job repaired, tested and cleaned up within two hours. Nice job guys!Read review on Google

Underground Water Leak Detection And Repair
WET GROUND? FIND THE LEAKING LINE.
An underground water leak can surface far from the failed pipe or remain hidden under landscaping or paving. We assess plumbing clues, clarify the private-property route, and discuss the access and repair scope that may be needed.

Underground Water Leak Detection And Repair: When To Call A Plumber
Water from a buried supply pipe can follow soil, slope, or hardscape before reaching the surface. A wet patch, unusually green strip, loss of pressure, or unexplained water use can point to a leak, but irrigation, drainage, and utility-side conditions may look similar. A clear assessment distinguishes a private service line from a public utility connection and helps decide whether the next step is focused repair or a larger replacement project.
Water Main Services Customer Reviews
Sergio came within 30 minutes of calling the company. He diagnosed the problem with my shower control valve quickly. He repaired it with a new cartridge. He also replaced my main water valve. He cleaned up after he was done with the job. I highly recommend this company.Read review on Google
My main water line broke on a rainy Sunday and not only did he come out that day within the hour but fixed my problem by the following day. Sergio and his team were professional and affordable and got the job done. I'm so glad I found him and will be calling him in the future for any plumbing issues.Read review on Yelp
WHAT WE'LL CHECK
Your Underground Water Leak Detection And Repair Options
We ask where the moisture appears, what lines run nearby, whether irrigation has been isolated, and what the water meter or home shutoff indicates if known. Accessible service connections and the route toward the building help narrow the suspected section. The visible wet area alone cannot establish the break location or ownership. We explain what can be assessed on private property and when the owner should contact the water utility to check utility-owned equipment or a public-side leak.
Repair A Confirmed Private Underground Leak
A focused repair may be appropriate when the failed section and connection points are clear and the surrounding service line remains suitable.
Replace A Deteriorated Section Or Service
If the line has repeat failures or condition concerns, replacing a broader section may be compared with another isolated excavation.

GOOD TO KNOW
Underground Water Leak Detection And Repair
Questions Answered.
Have a question about your plumbing? These answers cover what we’re often asked.
Who should I call for an underground water leak in my yard?
A plumber can assess a suspected private supply line, while the water utility can confirm responsibility for utility-owned equipment and public mains. If the boundary is unclear, contact both as appropriate.
What are signs of an underground water leak?
Persistent wet ground, unexplained water use, a pressure change, or erosion may be clues. Irrigation, drainage, and other sources can create similar conditions.
Can you locate an underground water leak without digging?
The available assessment depends on the symptoms, route, and accessible connections. Some leaks require excavation to confirm the exact pipe condition and complete a repair.
Does underground leak repair include restoring my yard or driveway?
The estimate should state plumbing and access work separately from landscaping, paving, and other surface restoration. Utility-owned lines and public utility work are outside the private plumbing scope.
