Build New From the Ground Up

Ground-up residential construction support in San Jose with full plumbing systems and coordinated trades.

Building a new home means starting with a blank slate and making decisions that affect how the house functions for decades. Every system needs to be planned, sequenced, and installed correctly the first time. In San Jose, where building codes are strict and lot conditions vary, new construction requires coordination between foundation crews, framers, plumbers, and inspectors from day one.

Cervantes Construction provides ground-up residential construction support with full plumbing systems installed to current code. The work includes water and gas line installation, drain and vent systems, fixture rough-ins, and final connections. Whether you're rebuilding after a loss or building a custom home, the plumbing is sequenced with framing and utilities so inspections happen on schedule and nothing gets delayed.

If you're planning new construction in San Jose and need reliable plumbing coordination, reach out to discuss how the project would be managed.

How Plumbing Fits Into the Build Sequence

Your plumbing work begins with underground rough-ins installed before the slab is poured. In San Jose, this includes water service lines, sewer laterals, and gas mains brought to the foundation edge. Once framing is complete, supply and drain lines are run through walls and floors, then pressure tested before drywall crews arrive.

When the home is finished, you'll have consistent water pressure, quiet drains, and fixtures that don't leak or require adjustment. Every connection is made to code, and all systems are tested under pressure before walls close, so there's no guessing about whether something will fail after you move in.

Materials include PEX or copper supply lines, ABS or PVC drains, and gas-rated piping where applicable. The work does not include landscaping irrigation, pool plumbing, or exterior hose bibs unless specified in the plan. Timelines depend on coordination with other trades, but plumbing milestones are scheduled to avoid delays in framing or inspection phases.

What Builders and Owners Ask Before Starting

New construction brings questions about timelines, inspections, and how plumbing integrates with the rest of the build. These are the concerns that come up most often before ground is broken.

What plumbing work happens before the slab is poured?
All underground drains, water service lines, and gas mains are installed and inspected before concrete is poured. This includes marking cleanouts and ensuring proper slope for waste lines.
How long does plumbing rough-in take?
Plumbing rough-in for a typical single-family home takes one to two weeks depending on layout complexity and inspection availability. The work must be completed and approved before insulation or drywall begins.
Why does plumbing get inspected multiple times?
Plumbing is inspected at underground, rough-in, and final stages to ensure code compliance and system integrity. Each inspection confirms that work meets standards before the next phase begins.
What happens if an inspection fails?
Failed inspections are corrected immediately, and a reinspection is scheduled once the issue is resolved. Common issues include improper venting, missing cleanouts, or incorrect pipe sizing, all of which are fixable without major rework.
When are fixtures installed in new construction?
Fixtures are installed after drywall, paint, and flooring are complete to avoid damage during other trades. Final connections are made once the home is ready for occupancy and the final plumbing inspection is scheduled.
