Underground and Under-Slab Plumbing in Castle Rock
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. Rocky mountain ground makes trenching for sewer and water lines harder, and lines must be buried below the local frost depth. 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.

Fixture Installation and Trim-Out in Castle Rock, CO
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 clean finish to your new construction plumbing. We work with many brands like Moen, Kohler, and American Standard to match your design specifications.
Rough-In Plumbing Services in Castle Rock
The rough-in phase is where the core plumbing system is installed within the walls, floors, and ceilings before drywall. This includes all supply lines, drain lines, and vent piping for every fixture. Our plumbers carefully plan and execute the rough-in, using durable fittings and ensuring all pipes are properly secured and leak-tested before inspection.
Gas Line Installation for New Homes in Castle Rock
If your new home will use natural gas for heating, cooking, or water heating, GFR Plumbing provides safe and code-compliant gas line installation. This involves running new gas lines from the main supply to all gas appliances. Our licensed plumbers confirm all connections are secure and tested for leaks, adhering to strict safety protocols for gas work.
Gas Line Installation for New Construction in Castle Rock, CO
Proper and safe gas line installation is a critical component of new construction plumbing. Our trained technicians install new gas lines for appliances like furnaces, water heaters, stoves, and outdoor grills. We use approved materials and conduct rigorous leak testing to ensure the safety and integrity of your gas system, meeting all Colorado and local Castle Rock codes.
Commercial and Multifamily New Construction in Castle Rock
We also plumb small commercial buildouts, offices, retail suites and multifamily projects. These jobs frequently require grease interceptors, backflow assemblies, commercial water heaters and ADA compliant fixtures. We read commercial plans, coordinate submittals and keep the general contractor informed through each inspection. Our crews scale up so plumbing never becomes the bottleneck on your schedule.
Gas Piping for New Homes in Castle Rock
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.

Sewer and Water Main Connections in Castle Rock, CO
Connecting your new home to the municipal sewer and water mains is a key step in new construction plumbing. GFR Plumbing handles all aspects of these connections, including excavation, trenching, pipe laying, and backfilling. We provide proper grading and sealing to prevent future leaks or blockages. Rocky mountain ground makes trenching for sewer and water lines slower, and lines must be buried below the local frost depth.

Frequently Asked Questions About New Construction Plumbing in Castle Rock
The cost of new construction plumbing in Castle Rock varies a lot 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 will be higher.
For new construction, we usually use PEX, or cross-linked polyethylene, for water supply lines due to its flexibility, durability, and resistance to corrosion. For drain, waste, and vent systems, we primarily use PVC piping because it's strong, lightweight, and cost-effective.
The timeline for new construction plumbing depends on the project's scope. The rough-in phase, which involves installing the hidden pipes, usually takes 1 to 2 weeks. The final fixture installation and connection usually takes another 3 to 5 days, spread out during the later stages of construction. We coordinate closely with your general contractor to stay on schedule.
Choosing a local plumber like GFR Plumbing for new construction in Castle Rock means working with professionals who understand local codes, soil conditions, and common building practices in Colorado.
