U.S. Engineering Company was established in Kansas City in 1893. Though to be fair, our roots run all the way back to 1855 – to a small shop in Cologne, Germany – owned and operated by Gustav Nottberg. Building on that storied history, we are now one of the most experienced, diversified and respected mechanical contractors in the United States. With three locations, we’ve continued to build on our reputation of providing quality mechanical contracting solutions that best fit owners’ needs. Our secret? We’ve continued to maximize owners’ investments in their facilities while staying true to the principals on which we were founded. Few firms are able to combine such a distinguished history with the sort of progressive, high-quality performance that defines our company – both as a top mechanical contractor and as a driving force within the communities in which we operate.
