Remodel and New-Construction Plumbing
Remodel plumbing is mostly about what happens before the walls close. JP Coastal Plumbing works on renovation and construction projects where supply, drain and vent lines need to be run, moved or updated, and coordinates that work around the rest of the project schedule.

Common reasons customers request this service
- A kitchen or bathroom remodel that moves fixtures from their existing locations
- New supply, drain and vent lines needed for an addition or conversion
- Updating aging piping that has been exposed during demolition
- Setting fixtures once finishes are in place
- Adding a laundry, utility sink or exterior connection
- Coordinating plumbing rough-in with other trades on a project
What the evaluation may involve
Every property is different, so the steps below describe a typical approach rather than a fixed checklist.
- Reviewing the project scope and where fixtures are planned to land
- Looking at what is currently in the walls, floor or crawlspace and how much is accessible
- Identifying where existing lines can be reused and where new runs are needed
- Talking through sequencing so plumbing lands at the right point in the project
Possible service and installation options
Which option makes sense depends on what the evaluation finds and on the condition of the existing plumbing.
- Rough-in of supply, drain and vent piping for relocated or added fixtures
- Relocating existing plumbing to suit a new layout
- Replacing exposed sections of aging piping while walls are open
- Final fixture setting and connection once finish work is complete
What to know before scheduling
- Have your layout, plans or fixture list available if the project has reached that stage.
- Note the project timeline and which trades are already scheduled.
- Mention whether demolition has started and how much plumbing is currently visible.
- Confirm who is handling permitting and inspection coordination for the project.
Questions about this service
Earlier is generally better. Fixture placement affects how lines are run, and decisions made before demolition tend to be 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 during demolition.
That depends on the scope and the local jurisdiction. Contact JP Coastal Plumbing to discuss how permitting will be handled for your specific project.
