Remodel & New-Construction Plumbing

A remodel lives or dies on what's behind the walls. Get the rough-in right and everything after goes smoothly; get it wrong and the tile comes back off. Gallegos Plumbing has plumbed remodels, additions, and new construction across Ventura County since 1996 — licensed, code-compliant work built to pass inspection, from a family-owned company that will still be here for the warranty call.

Bathroom & Kitchen Remodels

Moving a toilet, adding a double vanity, converting a tub to a walk-in shower, running gas and water to a relocated range or a pot filler — we handle the drain, supply, vent, and gas changes that make a new layout possible, and set the valves and fixtures once the finish work is done. One honest note we give every client at design stage: keeping fixtures near their existing locations is the single biggest cost saver in a remodel.

ADUs & Additions

Accessory dwelling units are the biggest thing happening in Ventura County housing, and every one needs a full plumbing system: new supply and drain runs, water heater, and a tie-in to the existing sewer line or septic system — a connection worth camera-inspecting before the project starts, not after the ADU is standing on top of a failing line.

With Your Contractor, or Direct

We work as the plumbing sub on your GC's schedule — rough-in, top-out, and finish phases coordinated with the build — or directly with you on plumbing-only projects. Either way the plumbing is built to code and ready for the inspection, and we are the ones standing there when it is walked.

Upfront, Honest Pricing

You approve a flat, upfront quote scoped from your actual plans before any work starts.

Planning a project? The earlier a plumber sees the drawings, the cheaper the plumbing gets — send us your plans and we'll flag the expensive surprises before demolition day.

Frequently Asked Questions

Does a bathroom renovation include plumbing?

Usually — but who does it matters. A general contractor typically subs the plumbing out; on plumbing-heavy projects you can also hire the plumber directly. Either way, moving or adding fixtures is licensed plumbing work, and it should be priced from the plans, not discovered mid-demo.

What is the most expensive part of a bathroom remodel?

Moving things. Relocating a toilet, shower, or sink means new drain, vent, and supply runs through the floor or walls — often the single biggest line item. Keeping fixtures where they are and upgrading in place is the classic budget saver, and we'll tell you honestly when a move is or isn't worth it.

Can a handyman do remodel plumbing?

Not the licensed parts. California caps unlicensed work at small jobs, and drain, vent, and gas changes need a licensed plumbing contractor. The failure mode isn't day one — it's the slow leak inside a finished wall a year later.

When should the plumber get involved in a remodel?

At design stage, before anything is final. Ten minutes with the plans catches the layout choices that would double the plumbing cost — and confirms the existing drain and supply lines can actually support what's being added.

How much does remodel plumbing cost?

It depends entirely on the layout — what's moving, what's being added, and what the existing lines can support. You approve a flat, upfront quote scoped from your plans before any work starts.
