Alex does an incredible job with an amazing eye for detail. He goes above and beyond to make sure his customers are satisfied. Highly recommend him for any of you welding needs and will continue to use him for subcontracting out metal jobs. Did a killer job on my exhaust for my truck as well. Cherry!!

Alex did awesome work welding some rock sliders on my truck. Worked with my schedule and made sure the job was done correctly. Welds look amazing and sliders are straight and solid! Will be going back to him for more custom work for the truck in the future!!
Was able to make modifications to my trailer same day! Great quality and respectful. Price was very reasonable as well. I recommend all the way. Appreciate the work!

Alex with Affiliation Welding worked directly for me for about 6 years before starting his own company. He proved himself over and over so I promoted him to head up my fabrication facility. He has done a great job for me as a welder both in metal and plastic on countless projects over the last many years. He always treated my customers, other employees and myself with utmost respect and honor. He is straight forward to work with and will tell you when a job is not a good fit. Few people could I recommend more highly to work with. He continues to do work for me on a consistent basis.
