Dependable New Construction Plumbing Services in Tacoma, WA

Guest House, ADU and Addition Plumbing in Tacoma, WA

Guest houses and additions need plumbing that ties into the existing house without overloading old drain lines. We locate the existing sewer, check its condition with a camera and verify there is enough fall to the new building. Supply lines can be branched from the main house or run as a separate service, depending on distance and pressure. We also handle the trenching between structures and restore the yard when we are done.

Fixture Installation and Trim-Out in Tacoma, WA

Once the rough-in is complete and walls are up, our team returns for fixture installation and trim-out. This includes connecting sinks, toilets, bathtubs, showers, dishwashers, and water heaters. We ensure all fixtures are properly seated, sealed, and functional, providing a professional finish to your new construction plumbing. We work with many brands like Moen, Kohler, and American Standard to match your design specifications.

Sewer and Drainage Systems in New Builds in Tacoma

A reliable sewer and drainage system is essential for any new property. We design and install complete sewer lines, septic systems, and storm drains, ensuring proper grading and connection to municipal services or on-site treatment systems. Crawlspaces and basements are both common in Washington homes, and a wet crawlspace is often the first sign of a drainage or plumbing problem. We account for soil movement on your lot, using durable PVC piping and careful bedding to prevent future blockages or pipe damage.

New Construction Plumbing Cost Planning in Tacoma, WA

Plumbing for a typical new single-family home often runs about 4 to 8 percent of total build cost, depending on fixture count and finish level. A modest three-bedroom home often lands between $12,000 and $25,000, while custom homes with multiple suites and outdoor kitchens run higher. Choices like a manifold PEX system, a recirculation loop and fixture grade move the number most. We break the bid out by phase so you can see exactly where the money goes.

Water Heater and Recirculation Installation in Tacoma, WA

New homes often use tank water heaters in the garage, basement or utility room, or tankless units on an exterior wall. We size the heater to your bathroom count and install gas or electric connections, venting, an expansion tank and drain pan where required. Many owners add a dedicated recirculation line during rough-in, which is far cheaper than retrofitting later. Soft water can be mildly corrosive to copper over time, which sometimes shows up as pinhole leaks in older supply lines. If treatment makes sense for your water, we recommend planning space for a softener or filter loop at the same time.

Gas Line Installation for New Construction in Tacoma, WA

Proper and safe gas line installation is a key component of new construction plumbing. Our certified technicians install new gas lines for appliances like furnaces, water heaters, stoves, and outdoor grills. We use approved materials and perform rigorous leak testing to ensure the safety and integrity of your gas system, meeting all Washington and local Tacoma codes.

Final Trim and Fixture Setting in Tacoma

At trim we install toilets, faucets, garbage disposals, dishwashers, ice maker boxes and laundry connections. We work with fixtures from Moen, Delta, Kohler, American Standard and the other brands builders often choose, or with owner-supplied fixtures. Every fixture is checked for flow, drainage and leaks, and angle stops are set straight and tight. We finish by running every fixture at once to verify the system drains and vents properly under load.

Gas Piping for New Homes in Tacoma

We size and install gas piping for ranges, water heaters, furnaces, fireplaces, pool heaters and outdoor kitchens. Black iron and CSST systems are both available, and CSST is bonded per manufacturer and code requirements. We calculate total BTU load and pipe length so every appliance gets enough pressure even when everything is running together. The system is pressure tested and inspected before the utility installs the meter.
