When You Need Underground Plumbing Repair

Buried lines fail out of sight, but they leave signs on the surface. A leaking water service shows up as a soggy patch of yard that never dries, a water meter that moves with everything off, a sudden pressure drop, or an unexplained jump in the water bill.

A broken sewer lateral announces itself with sewage odors outdoors, unusually green stripes in the lawn, small sinkholes along the pipe path, or main line backups that clear and return. A damaged gas line is an emergency you smell: leave the area, call the gas utility, and bring in a licensed contractor for the repair once the line is made safe.
Older neighborhoods around downtown Hollister, San Juan Bautista, and Watsonville still rely on original clay sewer laterals and galvanized water services.

Root intrusion in those aging lines is the most common failure we dig up.

Soggy patch in the yard, sewage smell outside, or a backup that keeps coming back? Tell us what you are seeing and we will find the failure.

What the Repair Process Looks Like

Good underground repair starts by finding the exact failure before digging. On sewer lines, a camera inspection shows the break, and the transmitter in the camera head lets us mark its position and depth on the surface.

Every excavation begins with USA North 811 utility marks, so existing gas, electric, water, and communication lines are identified first. We then dig at the failure point with our own equipment rather than trenching the whole line.
The damaged section is cut out and replaced with modern pipe and proper couplings, on correct bedding and slope. The repair is tested and, where a permit is required, inspected before backfill.
You see the failed pipe with your own eyes before we bury the fix.

Backfill is compacted in lifts to prevent settlement, and the surface is restored as close to original as conditions allow.

Repair a Section or Replace the Line?

A single break in an otherwise sound line is a spot repair. A line with failures at many joints, heavy corrosion, or root intrusion along its length is usually better replaced, because patching one section only moves the next failure a few feet down the pipe. We show you the camera footage or the exposed pipe and give you both prices when both make sense. Replacement also lets us upgrade old clay or galvanized pipe to modern material in one job.

How Long It Takes

A spot repair on a water service or sewer lateral usually takes one day, including excavation, repair, testing, and backfill. Full lateral or water service replacements take one to three days, depending on depth, length, and what sits above the line. Concrete, pavers, and mature landscaping add time for removal and restoration. Inspection scheduling can add calendar time where a permit is required. We explain the timeline before we dig.

What It Typically Costs

Repair cost depends on how deep the line is, what sits on top of it, the pipe material, and whether a spot repair or full replacement is the right call. A shallow break under open lawn is the simple end of the range; a deep sewer lateral under mature trees and a concrete driveway is the complex end. When you call, expect questions about the symptoms, the age of the home, and what covers the line. Estimates are free and itemized, covering excavation, materials, testing, inspection, backfill, and restoration. Because we own our excavation equipment, pricing and scheduling stay in our control.

Licensed, Bonded, and Insured

DAE Plumbing, Inc. holds California contractor licence 1047507 and is bonded and insured, with underground plumbing install and repair among our core specialties. Our fleet includes the service trucks, excavators, and skid steers this work demands. Buried repairs are the least forgiving plumbing work there is, because mistakes get covered with soil, so we test and inspect before anything goes back in the trench.

Local Factors in Hollister and the Central Coast

Soil and history shape underground repairs in our region. Expansive clay soils across the Hollister basin swell and shrink with the seasons, stressing rigid pipe and opening joints. Mature street trees send roots into those joints in older clay laterals. Coastal properties in Monterey and Santa Cruz Counties add corrosive soil that eats through metal lines. Seismic movement favors flexible modern materials and quality joint work in every repair. We work with the building departments in Hollister, San Benito County, and the surrounding counties every week.

Common Questions

Who fixes broken underground water and sewer lines in Hollister, CA?

DAE Plumbing, Inc., a licensed and insured contractor headquartered in Hollister, repairs and replaces underground water, sewer, and gas lines across San Benito, Santa Clara, Monterey, Santa Cruz, and San Mateo Counties. It operates its own excavation equipment, and estimates are free.

How can I tell if my underground water line is leaking?

Look for a soggy or unusually green patch of yard that never dries, or a water meter that moves with every fixture off. A drop in water pressure or a water bill that rises without extra use are also signs. A licensed plumber can confirm and pinpoint the leak before excavating.

What are the warning signs of a broken sewer lateral?

Sewage odors outside, main line backups that return after clearing, lush green stripes in the lawn along the pipe path, and settling soil or small sinkholes in the yard. Older clay laterals in the Hollister area are especially prone to root intrusion and joint failure.

Frequently Asked Questions

Yes. On sewer lines, we camera the pipe and use the transmitter in the camera head to mark the break's exact position and depth. That lets us dig one targeted hole instead of trenching the whole yard, which saves cost and landscaping.

One break in a sound line is a spot repair. Failures at several joints, heavy root intrusion along the line, or corroded and collapsed sections mean replacement is the better investment. We show you the evidence and price both options when both make sense.

Yes. We plan the excavation to minimize surface damage, dig precisely at the failure, and restore surfaces as close to original as conditions allow. Concrete, pavers, and mature landscaping add restoration scope, which we spell out in the estimate before work starts.

Yes, once the gas utility has made the line safe. We excavate, replace the damaged section with code-compliant pipe, pressure-test it, and coordinate the inspection before the gas is turned back on. If you smell gas, leave the area and call the utility first.

Yes. Underground repairs that require a permit are tested and inspected before backfill, and we compact in lifts so the trench does not settle. You also see the failed and replaced sections yourself before they are buried.
