Underground Plumbing Installation in Gilroy: What to Expect

Glen Loma Ranch and other Gilroy developments need new sewer, water and gas lines trenched in before building. We run our own trenching and excavation equipment, so one crew handles the whole job. Every line is bedded, inspected and backfilled to code.

How It Works

Locate, Plan & Free Estimate

We call in utility locates, assess the route, depth, and surface conditions, and deliver a free itemized estimate covering excavation through restoration.

Trench & Install to Code

Using our own excavation equipment, we trench, lay the line on proper bedding, slope and test it to code, and pass inspection before any backfill.

Backfill, Compact & Restore

We backfill in compacted lifts to prevent settlement, restore the surface, and leave you with a documented, inspected installation built to last.
