About Helmkamp Construction

Helmkamp Construction Company is a full service general contractor with self-perform and construction management experience. We have been serving the St. Louis and Metro East communities since 1938. Our focus is working for customers in the private market who have the need to buy construction in a repeat professional manner.

The major markets we perform work in are as follows:


Chemical, Food & Beverage, Logistics, Manufacturing, Metals, Petro Refining, Power, Utilities


Commercial, Data Communications, Education, Financial


Agriculture, Animal Health, Biomedical, Healthcare, Pharmaceutical

One of the advantages of working with Helmkamp is our ability to self perform excavations, concrete foundations and slabs, structural steel, rough and finish carpentry, labs, millwright equipment installations, and laser alignment/precision leveling tasks. At least half of our work is self-performed, making our team hands-on experts in many areas. This means our customers feel they can rely on Helmkamp to do the job right, as there is less of a need for a subcontractor in many cases.

Our main presence is in Illinois and Missouri, particularly in the St. Louis metropolitan area. However, Helmkamp has national capabilities and is qualified to perform out of state work for our customers. To date, Helmkamp has performed work in 25 states across the country.
