Professional Re-Piping
Over time, the pipes in your home can corrode, leak, and degrade, leading to low water pressure, rusty water, and the risk of catastrophic water damage. We specialize in whole-home re-piping services for Onalaska properties. Our expert team will assess the condition of your existing plumbing and replace old, failing materials with modern, durable piping. This crucial upgrade not only resolves current issues but also protects your home’s value and provides peace of mind for decades to come.
Expert Drain Cleaning and Services
A clogged or slow drain is more than just an annoyance; it can shut down a bathroom or kitchen and indicate a larger problem in your plumbing system. Our professional drain cleaning will clear even the most stubborn blockages from sinks, showers, tubs, and main sewer lines. Using advanced tools and techniques, our drain services not only remove the immediate clog but also clean the pipe walls to help prevent future buildup, ensuring your drains remain clear and free-flowing.

Water Heater Repair
A reliable supply of hot water is a daily necessity. If your water heater is leaking, making strange noises, or failing to heat your water, our technicians can help. We service and repair all makes and models, quickly diagnosing the issue and performing effective repairs to restore your hot water fast.

Well, Septic, and Sewer Line Solutions
For Onalaska properties with private systems, we offer a range of specialized services. If you’re experiencing low well water pressure, we can diagnose and service your well pump and pressure tank to restore strong, consistent flow. Our team is also equipped to handle septic system repairs to ensure proper function. For persistent drain issues, our state-of-the-art sewer camera inspections allow us to see deep inside your pipes to accurately locate blockages, breaks, or root intrusion without disruptive guesswork.
Kitchen and Bathroom Remodeling Plumbing
When you’re remodeling your kitchen or bathroom, the plumbing is a critical component of your project’s success. Our team works seamlessly with you and your contractors to ensure your vision comes to life. We handle everything from re-routing water and drain lines to professionally installing new sinks, faucets, toilets, showers, and tubs. We guarantee that all plumbing work is performed flawlessly and brought up to current codes, ensuring your newly remodeled space is as functional as it is beautiful!

Water Conditioning, Testing, and Treatment
The hard water common in the Onalaska area can take a toll on your plumbing fixtures and appliances, leading to damaging scale buildup. We provide comprehensive water testing services to identify hardness levels and other impurities. Based on these results, we can recommend and install effective water conditioning and treatment solutions, such as water softeners and whole-home filtration systems, to protect your plumbing, improve soap efficiency, and provide better-tasting, healthier water for your family.
