Testimonials

“Jim and Tom at OneFab have been fantastic from the get-go. They really understand the ins and outs of the winery process, from grape intake all the way to sending the wine out the door.

They're brilliant at turning our ideas into practical, real-world solutions (and often come up with even better ones). Their craftsmanship is top-notch, always reliable, totally professional, and they consistently deliver on time and within budget.”

“I highly recommend Tom and Jim and the OneFab team. They’ve developed helpful and creative solutions for our projects, which often involve complex designs and requirements.

They take the time to understand what we’re trying to achieve and map out design concepts for us to consider and select from. Their work is first-class, and they are reliable, professional, and great to work with.”

They’re reliable, easy to deal with, and bring a practical, problem-solving mindset to every job. The workmanship is always top quality, from pipework to tank upgrades to the catwalks we’ve built together, and every project is completed on time and to a high standard.”
