Supply Line Leak Repair in Madison
Water lines that run along basement ceilings and walls can leak at fittings, valves or pinholes. Water softeners are a common feature in many Wisconsin homes, helping protect water heaters, fixtures and appliances from scale. Water chemistry affects how fast copper corrodes, and older galvanized lines frequently rust from the inside. We locate the leak, replace the damaged section with copper or PEX and pressure test the repair. If the line shows widespread wear, we'll tell you whether a partial repipe makes more sense.

Waterproofing for Older Wisconsin Homes in Madison, WI
Many older homes in Madison and across Wisconsin were not built with modern waterproofing techniques, making them more prone to basement leaks. Wisconsin has a lot of older housing, and many homes still have cast iron drains, galvanized supply lines or clay sewer laterals. HKV Plumbing specializes in retrofitting older foundations with current solutions, addressing issues like failing mortar, porous concrete, and inadequate drainage. We preserve the integrity of historic structures while providing modern protection.
Foundation Crack Repair in Madison
Foundation cracks are a common entry point for basement water leaks, especially in homes built on soil that swells and shrinks. Freeze and thaw cycles move the ground each year, which can crack older clay and cast iron sewer laterals. We use epoxy and polyurethane injection techniques to seal these cracks, preventing water infiltration and reinforcing your foundation. Our methods are tailored to the specific type and size of the crack, ensuring a durable repair.
Emergency Basement Leak Repair in Madison, WI
A sudden basement leak can be a crisis, especially during heavy rains. HKV Plumbing provides emergency basement leak repair services in Madison, WI to address urgent water intrusion issues quickly. Our fast response team is equipped to perform immediate diagnostics and temporary or permanent repairs, preventing further damage to your property and belongings.
Exterior Waterproofing in Madison, WI
For a more complete solution, we offer exterior waterproofing, which involves excavating around your foundation, applying a waterproof membrane, and installing drainage boards. This method creates an impermeable barrier on the outside of your basement walls, providing strong protection against water intrusion. Boilers, furnaces and water heaters run hard through the winter, so seasonal maintenance helps prevent failures during deep cold.
Wall and Slab Seepage Repair in Madison
When water enters through foundation walls or the slab joint, the cause is usually surface water pooling against the house. Freeze and thaw cycles move the ground each year, which can crack older clay and cast iron sewer laterals. Dense or saturated soil can hold water near the foundation instead of letting it drain away. We seal penetrations where pipes pass through the wall and can install interior drain channels that carry seepage to a sump. We also recommend grading and gutter changes when outside water is the root cause.
Water Damage Assessment in Madison, WI
Before any repair, our team performs a thorough water damage assessment to identify the source and extent of your basement leak. This includes inspecting for mold growth, structural concerns, and damaged finishes. Our comprehensive approach ensures that all related issues are addressed for a full restoration of your Madison basement.

Sump Pump Installation and Repair in Madison
A properly functioning sump pump is crucial for preventing basement flooding, especially during heavy downpours. HKV Plumbing provides expert sump pump installation, repair, and maintenance services. We ensure your pump is correctly sized and installed to handle the water volume, giving you peace of mind.
