More than 50 years ago, Blau Sudden Service suddenly appeared on the local home comfort scene. The year was 1960, to be exact. Two full - and fulfilling - generations ago. From the beginning, we set out to be the very best provider of plumbing, heating, air conditioning, drain cleaning, and related services for home owners and light commercial operations throughout Southeast Wisconsin.
Blau Sudden Service is member of The Nexstar Network, an international "best practices" association of plumbing, heating & cooling, and electrical contractors. As such, we fully subscribe to our association's Code of Ethics, and practice all of its component parts daily. WE WILL SERVE our customers with integrity, competence, and objectivity.
If it's Broken, Leaking, Splashing, or Just Plain Not Working, It's Blau Sudden Service to the Rescue. And that begins with an annual home plumbing inspection. If you haven't had one in a while, or not at all, now's the time. During the process, we make sure everything is in proper working order. We look for problems in the making and show you how we can fix them quickly and more affordably.
At Blau Sudden Service, we can repair all water heater makes and models. We also provide expert water heater inspections that cover all working components and any potential safety hazards, such as gas or CO (carbon monoxide) leaks. When it's time for a new water heater, you can count on Blau for the expert advice and right equipment for any size house or family.
Traditional toilets use anywhere from 3.5 to 7 gallons of water per flush. With a family of four, that can amount to hundreds of gallons of water every day. In contrast, eco-friendly low-flow toilets use just 1.6 gallons per flush, max. Studies show that an average family of four will save 22,000 gallons of water per year and $100 on their water bill after switching to a low-flow toilet.

Very knowledgeable and willing to explain what he was doing and why. Even gave me tips on cleaning the AC unit. I will go nowhere else for my heating, cooling and plumbing. They installed my water heater in 2016, have serviced my main line several times and my furnace! Professional, reliable and on time when in need!
