New construction plumbing, built right from the start.
New construction is the one chance to get the plumbing right before the walls close. We handle rough-in through finish, to code.
Right from the ground up
The plumbing you build in is the plumbing you live with.
New construction is the rare moment when the plumbing can be done exactly right, before anything is covered up. The supply lines, drains, vents, and connections you build in now determine how the home performs for decades. Getting it right the first time means a home that works and a homeowner who isn’t chasing problems later.
We handle new construction plumbing from rough-in through finish. The rough-in stage, running the supply and drain lines, setting the vents, and placing everything for the planned fixtures, is where the careful work happens, because it all gets covered by walls and floors. We do it to code and we do it to last.
Then we come back at finish to set the fixtures, make the final connections, and test everything. The result is a home with plumbing that was planned and built properly, not retrofitted around problems. We’ll give you a clear scope and price for your project.

Oahu specifics
Building on Oahu.
New homes and additions on Oahu need plumbing designed for island living and built to local code. We handle the rough-in and finish for new construction with the same honest, do-it-right approach we bring to every job, just at the foundational stage where it matters most. Getting it right here means the homeowner isn’t dealing with avoidable problems down the road.
We’re glad to coordinate with your builder and stay in sync with the rest of the schedule so the plumbing stages line up with framing, inspection, and finish. For additions and ADUs especially, tying new plumbing into an existing home cleanly is exactly the kind of work we do, and if the existing lines are aging, our repiping service can bring those up to par at the same time.

What working with us looks like
Straightforward, start to finish.
The first thing we do on any new construction plumbing job is figure out what’s actually going on. We look at the real problem instead of guessing, and we explain what we find in plain language, no jargon, no scare tactics. You’ll know what’s wrong and what your options are before anything else happens.
Then you get a clear price. The number we quote is the number you pay, which is the whole reason John started Shoreline back in 2019 after watching another company do it the wrong way. A licensed plumber does the work, keeps you posted along the way, and cleans up the area before leaving. We finish by checking that everything runs the way it should.
None of that changes with the size of the job. A small new construction plumbing call and a big one get the same honest diagnosis, the same clear price, and the same crew that takes pride in the work and leaves your place clean. We would rather do it right and earn the next call than rush it and lose your trust, because the reviews our customers leave are the only advertising we really count on.
That approach is why so many of our customers call us back and ask for our crew by name. If you’ve got a new construction plumbing question or you’re ready to get on the schedule, reach out through our contact page or call (808) 445-3585. We answer, and we’ll give you a straight answer.
