“Sierra Nevada Brewing Co. has had the privilege of working with Tom Barnum and the talented crew at Barnum Mechanical for over 20 years. They were a valuable partner during several major expansions at our Chico, CA brewery, and have worked on a wide range of other projects over the years. Barnum Mechanical also played a significant role in the design and construction of our North Carolina greenfield brewery, from CAD and engineering help during the design phase to mobilizing a large field crew to assist in equipment installation and process piping.
They bring a high level of knowledge and understanding of food and beverage processing equipment, sanitary process design, and are competent in complex matrix piping and valve technology. Their attention to detail, stellar workmanship and artesian approach to design and installation continues to deliver value long after they have left the jobsite.”

We at J.J. Pfister appreciate the help Barnum Mechanical has provided us in our organic distillery in Sacramento, CA. They have helped us from the inception of our company and did a superb job with our process engineering needs. A distillery is a complex manufacturing plant and their craftsmanship and problem-solving abilities were greatly appreciated. We had an issue with a purchased part that the manufacturer could not solve but Barnum Mechanical did!”

Working with Barnum Mechanical for the past three years has opened my eyes to the value of selecting the correct partner for the project.  Superior quality and craftmanship, thoughtfulness of piping and equipment installations, and the ability to think outside of the box to get the work done in the safest and most efficient manner are exemplified by the Barnum Team and make them my go-to contractor for complicated piping and process installation projects.  When your project demands the highest quality of installation in challenging environments and tight timelines, the Barnum team will not disappoint.
Mitchell Hall, Sr. Project Manager

We selected Barnum Mechanical because they have designed and built so many breweries.  Not only were we impressed by how well the Barnum team cooperated to get things done, the quality of work is incredible.  If another vendor needed something such a cable tray, Barnum found time to get the work done efficiently all the while still staying on schedule with their own work.  There was no arguing about whose job it was, they just got it done for the good of the project.  Additionally, Barnum was instrumental in the design phase too— We had ideas about what we wanted and with so much brewery experience Barnum was able to help shape the design and the overall process.  We ended up with everything we wanted and more.  It was great working with them!

Bently Heritage Distillery
Barnum Mechanical Inc. functioned as our primary process installer for stainless piping, mechanical work around processing equipment, and punch list work during the trouble shooting phase of startup of our distillery in Minden, Nevada. Their work is impeccable and the pride they take in it is obvious. Not only did they deliver with bells and whistles on everything we asked of them, they also understood our desire to create a beautiful facility and paid incredible attention to detail on every project. I could not have been happier with their work and the quality of people they brought to our facility.
