We had Sean come over to my job and fabricate some railing and gate match existing. He did an outstanding job of matching design. Would highly recommend him.

We needed a certified structural welder for our custom home project. Sean responded right away and was able to work directly with our framers and timeline to keep the project moving with no interruptions. Very professional, would definitely recommend and will definitely be using Sean and his company again.

Sean did an amazing and professional job. We had expanded our deck requiring new metal railings for it along with a metal gate with a Native American thunderbird on it. But the challenge was that he had to match the existing railing that was fabricated over 20 years ago and create some artwork panels from renderings. His challenge was to make it look like it was all made at the same time. Well, it came out amazing, even to color matching the paint on the railings!
