Frequently Asked Questions
What is included in a plumbing rough-in?
A rough-in includes all drain, waste, and vent piping plus water supply lines installed within walls, floors, and ceilings — before insulation and drywall. Everything is positioned precisely for the finish fixtures.
How do I schedule a rough-in for a new build?
We coordinate directly with your GC or builder. Rough-in typically follows framing and precedes insulation. We'll show up exactly when you need us, pull our permits, and pass inspection.
Do you do rough-ins for room additions?
Yes. We handle all sizes — from a single bathroom addition to a full second-floor addition. We'll tie into your existing system and ensure the new rough-in integrates cleanly.
