Planning before the walls open
Walk-through
We look at the space, the existing lines and where drains and vents can go.
Scope and price
You receive a clear price based on the fixtures and the work involved.
Permit
We confirm what permits your city requires and coordinate the inspection.
Rough-in and finish
We run lines before drywall, test, then set fixtures after finish work.
Planning a remodel?
Call and tell us the rooms and fixtures involved. We will advise on the plumbing before you commit to a layout.
Why layout matters
Moving a toilet or shower across a room means moving the drain, and drain lines need slope and venting. On a slab, that may mean cutting concrete. On a raised floor, it is a matter of framing.
Postwar houses often have galvanized supply lines and cast iron or clay drains that may not suit a new fixture. A sound line is reused. A failing one is replaced while the wall is open, which saves cost.
| Project | What to plan | Inspection item |
|---|---|---|
| New bathroom | Drain, vent, supply, fan | Rough-in test before drywall |
| Kitchen move | Sink, dishwasher drain, gas | Gas pressure test |
| Laundry relocation | Standpipe, trap, supply box | Trap and vent |
| Gas appliance | Line size, shutoff, flexible connector | Leak test |
Codes and permits
Plumbing in California follows the California Plumbing Code, and new work normally needs a permit and inspection. The specific rules depend on the city, so ask the Pleasant Hill building division. We handle the plumbing side of the permit when we do the work.
Rough-in and finish: two visits, not one
Most remodel plumbing happens in two stages. The rough-in comes first, when walls are open: we run supply and drain lines, set the valve bodies and test everything under pressure. The finish comes after drywall and tile, when we set the fixtures, connect the supplies and test again.
Keeping those stages separate is what lets an inspector see the pipes before they are covered. It also lets you change a fixture choice late without reopening a wall, as long as the rough-in dimensions match.
- Confirm fixture models before the rough-in so the valve and drain locations match.
- Ask for a pressure test result before drywall closes.
- Keep the paperwork for the permit and any manufacturer warranty.
- Plan a shutoff valve at every fixture so future repairs do not need the main closed.
What affects installation cost
We give a clear price before work starts. Factors:
Planned remodel plumbing is not an insurance claim, though your contractor may include it in the project budget.
