The plain version
What new construction plumbing is
We take new construction plumbing for builders, general contractors, and owner-builders across Orange County: custom homes, ADUs, additions, and tenant improvements. The scope runs the full three stages — underground, rough-in, and finish — or any single stage where you need a licensed sub who can hold a date.
Underground is the stage with the least tolerance for error, because everything after it is poured over. Waste and vent below slab, supply penetrations, and the sewer connection out to the main all get set to the plan, sleeved where they should be sleeved, and pressure-tested before concrete. Getting the fall right underground is the difference between a building that drains and a callback nobody can reach.
Rough-in is DWV and supply through the framing, set for the fixture schedule and coordinated with framing, HVAC, and electrical so the trades are not solving each other's problems inside a wall cavity. Finish is fixtures, trim, connections, and a walkthrough that ends with everything operating.
What a GC is actually buying is schedule reliability and clean inspections. We quote from plans, show up on the date, and leave each stage in a condition the inspector signs.
When you need it
Any one of these is reason enough to have the line looked at.
- A custom home, ADU, or addition needing a licensed plumbing sub
- A plan set that needs takeoff and a firm number before you commit
- A stage that has to pass inspection on a date the whole schedule hangs on
- A sewer connection or underground run that has to be right before the pour
- A tenant improvement where existing underground is an unknown
On the day
How the job runs
Takeoff from the plans
We quote from the plan set and fixture schedule, flag anything that will not pass as drawn, and give you a stage-by-stage number rather than one lump.
Underground before the pour
Waste, vent, and supply below slab set to plan and to grade, sleeved and protected, then tested and inspected while everything is still visible.
Rough-in through the framing
DWV and supply run to the fixture schedule, coordinated with the other trades, nail-plated and secured, and left ready for the rough inspection.
Finish and walk it
Fixtures, trim, and connections installed, everything operated and checked, and a walkthrough with you or your super before final.
Money, plainly
What it costs
New construction is quoted from plans by stage, so your schedule of values gets real numbers instead of an allowance. Fixture count and grade, the number of bathrooms, the distance to the sewer connection, and the slab or raised-floor detail are what move a takeoff.
Change orders get priced when they arise and before the work happens, in writing. On a build with a lender draw schedule, surprises at the end are worse than the dollars involved, and we would rather have the awkward conversation in week three than at final.
Why Rooter-X for this
One licensed contractor across all three stages means nobody inherits somebody else's underground. When the same crew that set the below-slab work returns for rough and finish, the plan in the ground and the plan in the walls are the same plan.
Our sewer specialty is an asset before the building exists: the connection to the main, the fall on the underground, and a camera pass on the finished run are routine here rather than a subcontracted afterthought.

Questions we hear
Do you work from our plans, or do you design?
We install from your plan set and fixture schedule, and during takeoff we will flag anything that will not pass inspection as drawn — venting that does not work, fixture units over the line size, a cleanout with no access. Design-level changes go back to your designer or engineer, but you hear about the conflict before it is buried in a slab.
Can you hold a date on our schedule?
That is most of what a GC is buying, so we quote capacity honestly rather than taking a job we cannot staff. If the calendar is tight we will say so during the bid instead of confirming and then rescheduling you into somebody else's delay.
Who pulls the permits?
Either arrangement works. Many GCs carry the permit under their own license and we work under it; on owner-builder projects and smaller scopes we pull the plumbing permit ourselves. The important part is agreeing which before the first inspection is scheduled.
Do you take ADUs and additions, or only full builds?
Both, and ADUs are steady work here. They also carry a wrinkle worth pricing early: an ADU adds fixture units to an existing sewer line that was sized decades ago for the main house. Camera and capacity checks on that existing line belong in the planning stage, not in the punch list.
What happens if the inspector fails a stage?
We are there for the inspection where it helps, we correct anything cited at our cost when it is our work, and we get the re-inspection scheduled fast, because your framing crew is waiting behind us. Corrections that come from a plan conflict get documented and priced as the change order they actually are.
