Remodel and New Construction Plumbing
Remodel plumbing is mostly decided before anything is installed. Where fixtures land determines how lines run, and changes are far cheaper on paper than they are after the walls close. Getting involved early is the single biggest thing that keeps a project straightforward.

How a project runs
- Step 1
Planning
Reviewing the layout, fixture selections and what the existing plumbing can support. This is when changes are inexpensive.
- Step 2
Rough-in
Running supply and drain lines to the new fixture locations while the walls and floors are open, and coordinating with the other trades on site.
- Step 3
System installation
Setting the equipment the design calls for and connecting it into the property's system properly.
- Step 4
Fixture and finish work
Setting and connecting the finished fixtures once surfaces are in, and verifying everything functions before the space goes back into use.
Typical project types
- Kitchen remodels with relocated sinks, appliances or islands
- Bathroom remodels including tub-to-shower changes
- Additions requiring new supply and drain runs
- New construction plumbing coordinated with the build schedule
- Replacing sections of aging plumbing exposed during demolition
What demolition tends to reveal
Opening a wall in an older Central Coast home regularly turns up something the plans did not account for — previous repairs, unexpected routing, or piping in worse condition than the surface suggested.
When that happens you get a description of what was found and what the options are, along with the cost implications, before the scope changes. Surprises are part of remodeling; unexplained ones do not have to be.
Questions about this service
As early as possible. Fixture placement drives how lines are run, and decisions made before demolition are consistently less expensive than changes made after.
Sometimes. It depends on the condition of what is there, how far fixtures are moving and what becomes visible once things are open.
That depends on the scope and the local jurisdiction. Contact JP Coastal Plumbing to discuss how permitting will be handled for your specific project.
