Gas line installation, sized and done safely.
Adding a gas appliance? The line has to be sized and installed correctly. We run new gas lines safely and to code.
New gas, done right
Gas installation is licensed work for a reason.
Running a new gas line is not a job to improvise. A loose fitting or an undersized line isn’t just an inconvenience, it’s a safety issue. That’s why this is licensed work, and why we do it properly every time: correct materials, correct sizing, tested connections, and code compliance from start to finish.
We install new gas lines for ranges, dryers, tankless water heaters, outdoor kitchens, and other appliances. The most important part is sizing, the line has to deliver enough gas for the appliance to run the way it’s supposed to. An undersized line means an appliance that underperforms, so we get that right before anything else.
We’ll explain what’s involved in plain terms and give you a clear price before we start. Gas installation done right is invisible, the appliance just works, safely, and that’s exactly what we aim for.

Oahu specifics
Adding gas appliances in an island home.
A lot of our gas installation work comes alongside a remodel or an upgrade, a new gas range in a kitchen redo, a tankless water heater that needs a properly sized line, or an outdoor cooking setup. In each case, the line has to be sized for the appliance, or it won’t perform. We handle that part so your new appliance works the way it’s supposed to.
If your gas project is part of a bigger kitchen or bath remodel, we can coordinate it with the rest of the plumbing so the trades aren’t tripping over each other. And once a line is in, we test it under pressure and confirm every connection before we call it done, because with gas, close enough isn’t good enough.

What working with us looks like
Straightforward, start to finish.
The first thing we do on any gas line installation 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 gas line installation 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 gas line installation 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.
