Sean Byrnes Welding has been welding for many years in the Thornton NH area and beyond.

I have been a welder/fabricator since 1983, doing work ranging from structural steel and pipe welding to precision fabrication for the furnace/boiler/energy as well as military sectors. I decided it was time to take my talent on the road in 2003, and we began offering portable welding and machine work in our shop as well as a barge service on the lake and islands with our 26' pontoon barge and also with our 19' work boat. We began doing aluminum dock work and since then our work has varied from ornamental iron work, rails, stairs, gates & fireplace screens to custom aluminum dock configurations, custom headers, and boathouse gates. We specialize in the difficult; taking on many interesting projects all over New England. We pay close attention to detail and customer service and strive to meet or exceed customers expectations. The quality and integrity of our welding has and always will be our main priority.
