Gas Line Installation for New Homes in New Martinsville
If your new home will use natural gas for heating, cooking, or water heating, GJK 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.
Underground and Under-Slab Plumbing in New Martinsville
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, steep terrain is common across West Virginia, and many homes sit on hillsides where drainage and slope movement affect buried lines. 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.
Final Trim and Fixture Setting in New Martinsville
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 commonly specify, 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.
Fixture Installation and Finishing in New Martinsville, WV
Once the rough-in is complete and walls are up, GJK Plumbing handles the final installation of all plumbing fixtures. This includes sinks, toilets, showers, bathtubs, dishwashers, and washing machines. We ensure everything is perfectly aligned, sealed, and fully functional, providing a polished finish to your new home's plumbing system.
Gas Piping for New Homes in New Martinsville
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 runs at once. The system is pressure tested and inspected before the utility sets the meter.
Rough-In Plumbing Services in New Martinsville
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 meticulously plan and execute the rough-in, using high-quality fittings and ensuring all pipes are properly secured and leak-tested before inspection.
Commercial and Multifamily New Construction in New Martinsville
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 updated through each inspection. Our crews scale up so plumbing never becomes the bottleneck on your project.
