The Most Reliable Plumber

Jost Wilhelm Neuhaus 


For more than 100 years, my family has been running and operating a plumbing and heating business in Germany. The name Wilhelm came from my grandfather back home. After gaining more than 30 years of experience, I decided to follow in his footsteps and make my family proud by continuing our history.


While in Germany, I received training in Home Energy Consulting and I successfully managed to get a Journeyman License in Heating as well as a Master Plumbing License. In 2012, I moved to Canada and got my Red Seal Plumbing certificate. Backed by my experience, I opened my business more than 5 years ago. I started by doing small jobs on Kijiji, and now, I have helped numerous satisfied residential clients.
