Services
Residential Plumbing
We provide comprehensive residential plumbing solutions including repairs, fixture installations, and system upgrades. Our licensed technicians handle water heaters, softeners, sewer lines, and emergency leak repairs. Specializing in bathroom and kitchen remodels, we work with homeowners to create efficient, code-compliant plumbing systems while maintaining budget-conscious approaches.
Commercial Plumbing
Our commercial services cover new construction, maintenance, and emergency repairs for businesses in Milwaukee and Waukesha. We specialize in backflow prevention testing, pipe replacement, and system upgrades that meet regulatory requirements. With experience in industrial settings, we ensure minimal disruption to business operations while maintaining optimal plumbing functionality for clients ranging from small offices to large manufacturing facilities.
Sewer Cleaning
We offer professional sewer and drain cleaning to prevent clogs and maintain proper flow. Using modern equipment, we clear blockages in residential and commercial properties, addressing slow drains, complete backups, and preventative maintenance. Our technicians identify root causes like tree root intrusion or pipe corrosion, providing lasting solutions rather than temporary fixes for Milwaukee area properties.
Water Heater Installation
We install and service both traditional and tankless water heaters for residential and commercial clients. Our experts recommend energy-efficient Bradford-White models that reduce utility costs while ensuring reliable hot water supply. We handle proper venting, gas line connections, and electrical requirements, providing lifetime support for systems installed in Milwaukee homes and businesses since 1960.
Backflow Testing
Our certified technicians perform mandatory backflow prevention testing for commercial properties. We inspect, repair, and maintain reduced pressure (RP) valves to prevent contamination of public water systems. Serving Milwaukee businesses since 1960, we ensure compliance with local regulations through detailed testing reports and maintenance records for industrial and commercial clients.
