Inspection-Ready New Construction Plumbing Services in Trenton, NJ

Rough-In and Top-Out Plumbing in Trenton, NJ

Once framing is up, we run supply and vent lines through the walls and attic and set every stub-out for sinks, tubs, showers and appliances. We usually install PEX-A with a central manifold so each fixture gets its own line and shutoff. Shower valves are set at the heights you choose, and tub sets are installed and protected before the drywall is hung. A full pressure test is held for inspection so nothing hidden in the walls is ever a question.

Residential New Build Plumbing in Trenton

For new homes, our residential new construction plumbing includes the complete installation of water supply lines, drain waste vent systems, and gas lines. We confirm proper sizing and pressure for all fixtures, from showers to kitchen sinks, while accounting for local water quality and potential foundation movement. Much of New Jersey gets moderately hard to hard water, so scale collects inside water heaters, faucet aerators and fixture valves over time. Our process includes careful planning to prevent future slab leaks or drainage issues tied to the soil under your lot.

Guest House, ADU and Addition Plumbing in Trenton, NJ

Guest houses and additions need plumbing that ties into the existing house without overloading old drain lines. We locate the existing sewer, check its condition with a camera and confirm there is enough fall to the new building. Supply lines can be branched from the main house or run as a separate service, based on distance and pressure. We also handle the trenching between structures and restore the yard when we are done.

Underground and Under-Slab Plumbing in Trenton

The underground phase sets the drain, waste and vent layout that every fixture in the house will depend on. We trench, bed and slope PVC or ABS drain lines at a minimum quarter inch per foot and protect every pipe that passes through the slab or foundation with sleeves. Sandy soils near the shore drain quickly but shift easily, which can stress buried water lines and sewer laterals over the years. We compact bedding carefully and avoid rigid points that could stress the pipe as the ground moves. Each line is water tested and left visible for the inspector before your concrete contractor pours.

Water Heater and Recirculation Installation in Trenton, NJ

New homes commonly use tank water heaters in the garage, basement or utility room, or tankless units on an exterior wall. We size the heater to your bathroom count and install gas or electric connections, venting, an expansion tank and drain pan where required. Many owners add a dedicated recirculation line during rough-in, which is far cheaper than retrofitting later. Much of New Jersey gets moderately hard to hard water, so scale builds up inside water heaters, faucet aerators and fixture valves over time. If treatment makes sense for your water, we recommend planning space for a softener or filter loop at the same time.

Final Trim and Fixture Setting in Trenton

At trim we install toilets, faucets, garbage disposals, dishwashers, ice maker boxes and laundry connections. We work with fixtures from Moen, Delta, Kohler, American Standard and the other brands builders often choose, or with owner-supplied fixtures. Every fixture is checked for flow, drainage and leaks, and angle stops are set straight and tight. We finish by running every fixture at once to verify the system drains and vents properly under load.
