Plumbing is part of finishing the house, not a separate errand
Builders deliver a home with the basics stubbed in and a backyard that is bare dirt. The moment you want an outdoor kitchen, a sink on the patio, a water feature, a fire pit on a gas line, or a grill plumbed for natural gas, you are into new supply, drain, and gas runs. Inside, buyers finishing a home often want a pot filler, a laundry sink, a filtration line, a second water heater, or a repipe to move fixtures where the floor plan actually needs them. All of that is plumbing, and it lands in the middle of a construction project, not on its own.
Run in isolation, plumbing gets awkward. The trench for a backyard water line has to coordinate with hardscape base prep. A gas line to a fire feature has to be set before the patio is poured over it. A drain to an outdoor sink has to tie into the right slope before the concrete goes down. When a separate plumber shows up after the fact, walls get opened twice and patios get cut apart to reach a line that should have gone in during the rough stage.
One contractor sequencing plumbing with the rest of the build
Five Stars Builders plans plumbing alongside the hardscape, gas, electrical, and finish work under one contract. We rough in supply, drain, and gas lines before slabs and patios close over them, set fixtures and water heaters as the finish work comes together, and pressure-test lines before anything is buried or covered. You get one team accountable for the sequence, so the trench, the line, the test, and the surface above it are all coordinated instead of fought over between subcontractors.
Why choose us
Plumbing planned into the build, tested before it is buried.
Water and gas lines are the part of a project you never want to reopen. Here is how we run plumbing as part of the larger build so it goes in once and goes in right.
CSLB License #1103138. Verifiable through the Contractors State License Board (CSLB) before you sign anything.
Supply, drain, and gas lines are set and pressure-tested before patios, slabs, and walls cover them, so nothing has to be cut apart later to reach a buried line.
Gas runs to fire features, fire pits, grills, and outdoor kitchens sized and set as part of the patio build, coordinated with the hardscape base before concrete goes down.
Plumbing planned alongside hardscape, gas, and finish work under one contract. No coordinating a separate plumber against your concrete and construction crews yourself.

Our process
We start with a site walk to see how you want to use the space, an outdoor kitchen, a water feature, a fire pit, a laundry addition, or a repipe to move fixtures, and we map the runs against the rest of the build. From there we plan where supply, drain, and gas lines have to sit before patios, slabs, or walls close over them. We rough in and pressure-test every line, then set fixtures and water heaters as the finish work comes together. We finish with a walkthrough so you know where the lines run and how each connection is served.
