Underground and Under-Slab Plumbing in Janesville

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. Glacial soils in Wisconsin range from heavy clay to sand and gravel, which affects how water moves around foundations and 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.

Gas Piping for New Homes in Janesville

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 sets the meter.

Water Heater and Recirculation Installation in Janesville, WI

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 much less expensive than retrofitting later. Water softeners are a standard feature in many Wisconsin homes, helping protect water heaters, fixtures and appliances from scale. If treatment makes sense for your water, we suggest planning space for a softener or filter loop at the same time.

Commercial and Multifamily New Construction in Janesville

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.

Rough-In and Top-Out Plumbing in Janesville, WI

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 usually 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 a question.
