Client Feedback

We had an amazing experience working with Joe at Demel Fabrications on a couple of commercial projects in the Bay Area and San Diego. One was a custom steel platform for boiler access, and the other was a custom staircase for a life science building connecting two floors. Both projects went as smoothly as anyone could hope for, thanks to Joe’s involvement from start to finish. Joe really took charge of the staircase project. He created detailed 3D renderings, worked closely with the...

I recently had the pleasure of collaborating with Joe and DeMel Fabrication to design and fabricate custom wildlife barrier screens for a water treatment plant operated by a local/state water agency to prevent wildlife in areas prone to entry. From the initial site visit, Joe took the time to understand specific project needs and concerns. He offered insightful recommendations, tailored solutions that addressed the issues, satisfied our requirements, and ensured functionality without compromising operational efficiency. The fabricated barrier screens were of exceptional quality...

Joe is the consummate professional. His attention to detail and the quality of his work is among the best in the industry. He's full service, able to handle design, fabrication, and install. In a world full of shoddy work, poor communication, corner-cutting, etc., Joe is a breath of fresh air. I would recommend him for any ornamental and structural fabrication.

Tube Service Co

Joe is the man. He is beyond talented and a great person to deal with. Not only is he a expert in the craft he was also very knowledgable in every other aspect of construction. I had an idea for a design and within a week he had drawings done for me. Few months later my vision came to life. I highly recommend DeMel Fabrication! Looking forward to my next project with him!

Joseph worked on structural columns and beams for my home build. He was easy to contact throughout the process, and his communication was great from the bid through delivery! He was very easy to work with and, most importantly, delivered a quality product on time.
