Whole-Home PEX Repiping in Janesville
If your home has old, corroded or leaking pipes made of galvanized steel or polybutylene, a whole-home PEX repipe is an effective solution. We remove the outdated piping and install a complete PEX system, improving water pressure and water quality and eliminating costly leaks. This comprehensive service leaves your entire plumbing system modern, efficient and built to last for decades in your Janesville home.

Leak Repair with PEX in Janesville, WI
For specific pipe leaks, PEX can be used to repair or replace sections of damaged piping. Our plumbers can isolate the damaged section and tie in PEX, providing a durable and flexible fix that holds up to future pressures. This targeted approach is cost-effective for localized issues and brings the benefits of PEX to problem areas of your existing plumbing in Janesville, WI.
Copper to PEX Conversions in Janesville
Copper lines can develop pinhole leaks from water chemistry, high velocity and sometimes soil contact under slabs. Hard water is common across much of Wisconsin, especially where supply comes from groundwater moving through limestone and dolomite. Once a home has had several pinhole leaks, more usually follow. Converting to PEX stops the cycle and reduces the risk of hidden water damage. We use approved transition fittings wherever new PEX connects to existing copper stubs or valves.
PEX-A Expansion Fitting Systems in Janesville, WI
PEX-A, such as Uponor, uses an expansion tool to stretch the pipe and a ring over the fitting, which then shrinks back into a tight seal. The fittings have a larger inner diameter, so flow restriction is lower. PEX-A is also more flexible and can recover from kinks with a heat gun. It is our favored choice for many full repipes.
Commercial PEX Pipe Installation in Janesville
Beyond residential work, HKV Plumbing also provides commercial PEX pipe installation for businesses in Janesville. PEX offers many advantages for commercial properties, including durability, resistance to harsh chemicals and cost savings on installation. We work efficiently to minimize disruption to your business during any commercial plumbing upgrade or new installation.
PEX Repipe Cost Comparison in Janesville, WI
PEX repipes typically cost less than copper repipes because the material is less expensive and installs faster. The total depends on the number of bathrooms, the home's size and how accessible the attic and walls are. Drywall patching and texture matching are often included or quoted separately. We give you a detailed estimate so you can compare PEX-A, PEX-B and copper options together.
Hydronic Heating with PEX in Janesville
PEX is also a premier choice for hydronic heating systems, including radiant floor heating. Its ability to withstand high temperatures and resist corrosion makes it well suited for circulating hot water. If you are considering radiant heat for a specific area of your home or business in Janesville, PEX is the pipe to use.

PEX Main Water Line Installation in Janesville
The main water line brings water into your home, and a failing one can cause serious issues. We provide expert PEX main water line installation, replacing old, damaged lines with durable PEX. This upgrade improves water flow, reduces the risk of future leaks and offers strong resistance to ground shifting and corrosion. Our team handles proper trenching and the connection to your municipal supply.

Small repairs are possible for handy homeowners, but a full repipe requires proper sizing, support spacing and code compliance. Mistakes behind walls can cause hidden leaks and failed inspections.
