Plumbing Services in Hayward, Oakland, and San Francisco, CA

Plumbing is a critical part of any remodel or new construction project. Done right, it stays out of sight and works flawlessly for decades. At C.J. Skeeles General Contractor, we provide plumbing services across Hayward, Oakland, and San Francisco, CA, specifically for new builds, additions, and renovations. Our work covers everything from rough-in piping and drain layouts to fixture installation and system integration.


Because we focus on full-project construction and remodeling, our plumbing services are tied directly into broader structural and layout changes. That means every pipe, valve, and connection is coordinated with framing, electrical, and finish work, reducing delays and ensuring everything fits and flows as it should.

Rough-In Plumbing for Construction Projects

Every successful plumbing system starts with a solid rough-in. This is where water supply lines and drain-waste-vent systems are installed within the walls, floors, and ceilings before finishes are applied. We install rough-in plumbing during the early stages of both residential and commercial construction, making sure the entire system is aligned with the architectural layout and code requirements.


In Hayward, Oakland, and San Francisco, CA, rough-in work must pass inspection before walls can be closed. That’s why our team takes extra care during this stage, pressure-testing lines, confirming slope and drain placement, and accounting for fixture location down to the inch. Whether the project involves a single bathroom or a full multi-unit layout, we get the backbone of the plumbing system right from the start.

Water and Waste Line Installation

Running water and waste lines across a building requires strategic planning, especially in remodels where existing infrastructure might not support modern usage. We assess existing pipes and determine whether to integrate or replace lines to accommodate new kitchens, bathrooms, or laundry areas.


In many Hayward, Oakland, and San Francisco, CA homes, galvanized or cast iron pipes are still in use and may require full replacement. For new construction, we install PEX, copper, and PVC based on the design plan, water pressure requirements, and code standards. Our work ensures clean, reliable water flow and safe wastewater disposal without pressure drops, backups, or leaks.

Fixture Installation and Final Trim-Out

Once the drywall is up and the finish work begins, we return to complete the final plumbing trim-out. This includes the installation of toilets, sinks, faucets, showers, tubs, and appliance connections. Each fixture is installed according to manufacturer specs and tested for leaks, proper drainage, and secure fittings.


We also make sure that everything is aligned aesthetically and functionally. That means centered valves, level installations, and accessible shutoffs—all of which contribute to a more polished and user-friendly space.



In larger commercial projects, this phase may include utility sinks, commercial-grade fixtures, and backflow prevention systems.

Remodel-Specific Plumbing Solutions

Remodeling often brings unique plumbing challenges. Wall layouts shift, fixtures get relocated, and older pipes need to be updated or rerouted. Our team specializes in adapting plumbing systems during kitchen and bathroom renovations to ensure that the new layout works seamlessly with the home’s existing plumbing infrastructure—or replaces it when necessary.

This includes:

 – Rerouting supply and drain lines to fit new cabinetry or wall structures

 – Adding plumbing for new bathrooms or laundry areas

 – Replacing old shutoffs and valves during fixture upgrades



We work alongside electricians and framers throughout each remodeling phase to keep all systems aligned and moving on schedule.
