Underground and Under-Slab Plumbing in Boulder
The underground phase sets the drain, waste and vent layout that every fixture in the house will depend 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. Basements are common in Colorado, and shifting soil can crack floor drains, sewer lines, and basement walls over time. We compact bedding carefully and avoid rigid points that could stress the pipe as the ground moves. Each line is water tested and left visible for the inspector before your concrete contractor pours.
Water Heater Installation for New Builds in Boulder
Selecting and installing the right water heater is crucial for any new construction. We provide professional installation of traditional tank-style and tankless water heaters, considering your property's hot water demands and energy efficiency goals. Our plumbers ensure correct sizing, venting, and gas or electrical connections, adhering to all safety regulations for new homes in Boulder.
Final Trim and Fixture Setting in Boulder
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.

Once the rough-in is complete and walls are up, GFR Plumbing handles the final installation of all plumbing fixtures.

Frequently Asked Questions About New Construction Plumbing in Boulder
The cost of new construction plumbing in Boulder varies widely based on the size and complexity of the project, number of bathrooms, and fixture choices. For a standard 3-bedroom, 2-bathroom home, rough-in and finish plumbing can range from $10,000 to $25,000. Commercial projects or luxury homes with advanced systems run higher.
Yes, our skilled team can assist with the plumbing design and layout for your new home. We work with your architectural plans to optimize water flow, drain efficiency, and fixture placement. Our goal is to create a functional, efficient, and code-compliant plumbing system that meets your family's needs.
Choosing a local plumber like GFR Plumbing for new construction in Boulder means working with professionals who understand local codes, soil conditions, and common building practices in Colorado. We have established relationships with local suppliers and inspectors, ensuring a smoother and more efficient project.
Yes, we can integrate a water softening system into your new construction plumbing design. Mountain homes in Colorado frequently rely on private wells, which may need treatment for iron, manganese, or other minerals. A softener loop is easy to add during the rough-in phase to protect your entire plumbing system and appliances from mineral buildup.
Several inspections are required during new construction plumbing. These typically include an underground or rough-in inspection before walls are closed, a top-out inspection if applicable, and a final inspection after all fixtures are installed and the system is operational. We schedule and coordinate all inspections to ensure compliance.
For new construction plumbing, we primarily use PEX piping for water supply lines due to its flexibility, durability, and resistance to scale build-up. For drain, waste, and vent systems, we use PVC pipes, which are corrosion-resistant and long-lasting.
We can run a dedicated return line during rough-in so hot water reaches distant bathrooms in seconds. A dedicated line works better than retrofit crossover valves and adds about $800 to $2,000 depending on layout. It also saves the water that would otherwise run down the drain while you wait for hot water.
Yes, virtually all new construction plumbing projects in Boulder, CO require permits from the local building department. GFR Plumbing handles all necessary permit applications and ensures that all work passes required inspections at each stage of the project.
