Copper Fitting and Valve Repair in Oshkosh
Angle stops, shutoff valves and copper fittings under sinks and behind toilets can weep or seize over time. Hard water minerals build up inside valves and prevent them from closing.

Burst Copper Pipe Repair in Oshkosh, WI
A burst copper pipe is a plumbing emergency that requires immediate attention, especially during hard freezes.

We promptly isolate the leak, remove the damaged section and replace it with new copper piping, restoring your system to full function and protecting it against future freezes.

Frequently Asked Questions About Copper Pipe Leak Repair in Oshkosh
Accessible copper leak repairs usually cost $250 to $650. Repairs inside finished walls or ceilings usually range from $500 to $1,500 before drywall patching. Slab leak repairs on copper lines frequently run $1,500 to $4,000.
We work with all standard types and brands of copper piping found in residential and commercial properties, including Type M, Type L and Type K copper pipes. Our repairs use high-quality copper and fittings from reputable manufacturers like Mueller Streamline and Cerro Flow Products.
Most straightforward copper pipe leak repairs, such as fixing an accessible pinhole leak or a single joint, can be completed within one to four hours. More complex issues, like leaks under a slab or extensive re-piping, may take a full day or sometimes multiple days, depending on the scope of work.
Copper pipes can leak due to several factors, including corrosion from water chemistry when the pH is too acidic or alkaline, aggressive soil conditions, high water pressure, poor installation or physical damage from foundation shifts. Hard water is common across much of Wisconsin, especially where supply comes from groundwater moving through limestone and dolomite. Pinhole leaks usually result from long-term internal corrosion.
If you discover a copper pipe leak, the first step is to locate and shut off the main water supply to your home to prevent further water damage. Then, contact HKV Plumbing right away at (414) 432-4641 for emergency service. Clear the area of any valuables and begin to collect any standing water.
A repair clamp or epoxy can buy time in an emergency, but they are not permanent fixes. A plumber should cut out the damaged section and install proper fittings, especially inside walls.
Copper pipe leaks are commonly caused by corrosion, especially from hard or acidic water. Hard water is common across much of Wisconsin, especially where supply comes from groundwater moving through limestone and dolomite. Other causes include excessive water pressure, improper installation, shifting foundations putting stress on joints and freezing temperatures that can cause pipes to burst. Pinhole leaks are a typical symptom of internal corrosion.
We typically use Type L copper, which has thicker walls than Type M and lasts longer. In some situations we use ProPress fittings or a PEX transition.
