At Cast & Copper Plumbing, we believe great homes start with reliable plumbing done the right way. As the residential plumbing division of J&J Contractors I LLC, our work is built on craftsmanship, professionalism, and attention to detail. We focus on residential plumbing for new construction and remodeling projects, working closely with builders, contractors, and homeowners to make sure every system is carefully planned and properly installed. From the first phase of a project through final inspection, our goal is simple: do it right the first time so it performs the way it should for years to come.
We offer a full range of residential plumbing services designed to support both new builds and renovations. Our work includes new construction plumbing systems, remodeling plumbing, water heater installation and replacement, and fixture and faucet installation. We also design and install radon mitigation systems that meet Wisconsin building codes and help maintain safer indoor air quality. Every project is approached with a clear plan, steady communication, and a focus on long term performance, so the plumbing works seamlessly with the rest of the home.
Cast & Copper Plumbing proudly serves homeowners throughout southeastern Wisconsin, typically within a 35-mile radius of Milwaukee. Our service area includes Milwaukee County communities like Bay View, Franklin, Greendale, Greenfield, Oak Creek, Whitefish Bay, Fox Point, and Shorewood. We also work throughout Waukesha County in areas such as Brookfield, Pewaukee, Delafield, Oconomowoc, and New Berlin, along with Ozaukee County communities including Mequon, Cedarburg, and Grafton. Even if your project falls just outside these areas, we welcome you to reach out. We are always happy to discuss your project and see how we can help bring dependable, high-quality plumbing to your home.
In addition to new construction and remodeling, Cast & Copper Plumbing also works directly with homeowners to handle a wide range of residential plumbing needs. We provide services such as faucet and toilet replacements, garbage disposal installation, water heater replacement and conversions, sump pump replacements, and interior leak repairs. Our team also handles gas line work, including additions and leak repairs, along with updating or rerouting water and waste lines as needed. Whether it is upgrading fixtures, preparing for future improvements, or addressing specific plumbing issues within the home, we bring the same level of care, planning, and precision to every service call.
