Client Testimonials

Richard G. Pascuzzo Former President, All American Crane Maintenance

I’ve used the services of California On-Site Welding and Dave Cutsinger for commercial, industrial and residential jobs. They are prompt, fairly priced, reliable and provide high quality solutions to complex fabrication challenges. The welds are some of the finest I’ve seen and the selection of the right tool for the right job is always available due to their extensive inventory of welding and fabricating equipment. California Onsite Welding has been a part of many projects in the past and will continue as such, well into the future.

Dave, from California on site welding came out to work on my feather light Weekend Warrior. Since my toy hauler was originally built for light trucks, and had mileage. I started to notice structural cracks in the welding joints that held the hangers for the leaf springs. This was causing additional structural damage on the trailer. Dave was extremely professional. I had google drawings on fixes others had performed. Dave, went beyond what I call normal work. Dave made recommendations of my pictures from Google, Dave welded pieces of steel in spots that others would take the short/easy approach. Without adding much weight, my trailer is now in better structural integrity that the factory model. I have taken several trips since Dave performed the work. The trailer tracks true, and is able to handle the rough terrain when I go to the desert. In my experience, I will never use anyone but Dave at Californiaonsitewelding versus anyone else. Dave, thank you for your meticulous and excellent workmanship. A very happy customer.
