New Construction Plumbing Cost Planning in Chapel Hill, NC

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 affect the price the most. We break the bid out by phase so you can see exactly where the money goes.

Rough-In and Top-Out Plumbing in Chapel Hill, NC

Once framing is up, we run supply and vent lines through the walls and attic and set every stub-out for sinks, tubs, showers and appliances. We typically install PEX-A with a central manifold so each fixture gets its own line and shutoff. Shower valves are set at the heights you choose, and tub sets are installed and protected before the drywall goes on. A full pressure test is held for inspection so nothing hidden in the walls is ever in doubt.

Fixture Installation and Trim-Out in Chapel Hill, NC

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 make sure 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.

Gas Line Installation for New Homes in Chapel Hill

If your new home will use natural gas for heating, cooking, or water heating, HFN Plumbing provides safe and code-compliant gas line installation. This involves running new gas lines from the main supply to all gas equipment. Our licensed plumbers ensure all connections are secure and tested for leaks, adhering to strict safety protocols for gas work.

Underground and Under-Slab Plumbing in Chapel Hill

The underground phase sets the drain, waste and vent layout that every fixture in the house will rely on. We trench, bed and slope PVC or ABS drain lines at a minimum quarter inch per foot and protect every pipe that passes through the slab or foundation with sleeves. Coastal areas have sandy soil and high water tables, which affect how sewer lines and septic systems function. We compact bedding carefully and avoid rigid points that could stress the pipe as the ground moves. Each line is water tested and left exposed for the inspector before your concrete contractor pours.

Final Trim and Fixture Setting in Chapel Hill

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 confirm the system drains and vents properly under load.

Plumbing Rough-In Services in Chapel Hill

The rough-in phase is the backbone of your new construction plumbing system. This involves installing all underground and in-wall piping before concrete is poured and walls are closed. We precisely lay out and connect all water supply, drain, and vent pipes according to architectural plans and local Chapel Hill codes. Using durable PEX or copper piping, we ensure secure, leak-free connections that will serve your property for decades.

Sewer and Drainage Systems in New Builds in Chapel Hill

A dependable 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. Coastal areas have sandy soil and high water tables, which affect how sewer lines and septic systems function. We account for soil movement on your lot, using durable PVC piping and careful bedding to prevent future blockages or pipe damage.
