About Us

Our History

Jantzi Plumbing was started in 2001 by Jeff Jantzi, a licensed plumber. For a few months after he started the business he worked all by himself. In the summer of 2001 he hired his first employee. 

Jeff started out with doing mostly plumbing service and agricultural projects, both of which are still an integral part of the business. Jantzi Plumbing has now expanded to include plumbing in custom homes, radiant floor heat, boilers, water treatment, HVAC, gas work, and commercial projects. 

In 2008 Jantzi Plumbing took over for A-1 Water Systems which had been owned and operated by Ken Erb for 20 years. A-1 Water Systems specialized in pump and well works, as well as water treatment. Ken has now been working with Jantzi Plumbing for over 10 years and is doing what he has always specialized in.

 In 2011 Jantzi Plumbing built a brand new facility just outside of Wellesley. This facility has been great and has given us more exposure as well as much more room to grow the company.

 In 2017 Jantzi Plumbing took over a small local HVAC company. This involves furnace and air conditioning installs, both new and existing, forced air systems, and routine maintenance. This has allowed us to expand our field of work and grow our company even more.

 Since 2001 Jantzi Plumbing has greatly grown in size, we have a wider variety of services offered and have a larger customer base. Jantzi Plumbing is now much more than just Jeff Jantzi, Jeff and Becky have taken on three partners ; Darryk Martin, Darryl Streicher, and Kevin Bast. And we now have 32 full time and part time employees in 2019 that all excel in different parts of the company and work together to make Jantzi Plumbing the company that it is.
