Our Story

      C.A. Esthus was founded by Combat Wounded US Army Veteran Colby A Esthus in 2020 at the age of 29, with the goal of being able to offer Residents, Business Owners and Municipalities reliable and efficient services every time they need them.  Since incorporation in 2020 Colby has built a proven reputation for quick emergency response times with quality and safe work practices.

     In 2019 Colby Started Offering Mobile Welding Services on the Side while Working full time and traveling for a large construction company. A year and a half after that Colby moved into his first shop where we are today, The move was huge step into being able to expand our services and continue to work year round in bad weather, along with adding more tooling to the business.

     Today we are proud to say On-Site Welding is still the core focus of C.A. Esthus, but along with that we are proud to offer full shop Welding and Fabrication Services, Heavy Equipment Repair, Facilities/ Industrial Maintenance, Site Work, Concrete/ Masonry & Land Management Services, for Residential, Commercial, Industrial & Municipal Clients.
