New Construction & Remodels

Our dedicated New Construction department has been at the core of Pacific Coast Plumbing since the beginning. For nearly 50 years, we've specialized in high-end custom residential projects, partnering with some of the top general contractors in Los Angeles to bring custom homes to life from the ground up. Our experienced construction team understands the level of precision and coordination these builds require and we take pride in delivering plumbing systems that are as functional as they are flawlessly integrated into the design. From initial planning to final fixture installation, we’re committed to quality and clear communication.

Our Plumbing Process

  • Group of people reviewing architectural blueprints on a wooden table with a laptop, calculator, and writing instruments.

    Pre-Planning

    During this first phase, we collaborate closely with homeowners, builders, architects, and designers to review plans and create a clear game plan for groundwork and installation—ensuring everything aligns with the designer’s vision and project goals.

  • Construction site with large black pipes laid in a trench, construction equipment, and fencing in an urban area.

    Groundwork

    This phase is done before the foundation is poured. It involves laying the underground water supply and drainage lines. It includes sewer lines, water mains, and drains that go under the slab.

  • Interior view of a house under construction, showing exposed wooden framing and plumbing pipes for water supply.

    Rough-In

    Once the framing is complete, we run all interior water supply and drainage lines. This includes preparing spaces for future sinks, tubs, showers, and other fixtures. It’s all the essential work that gets hidden behind walls and makes everything function smoothly.

  • Set Finish

    This is where it all comes together. After walls, floors, and tile are in place, we install your plumbing fixtures and appliances—like faucets, toilets, and water heaters. We make sure everything is connected, working perfectly, and ready for everyday use.
