What is JAK Builders?

We offer design consultation, site planning, and self-performing erection services of pre-engineered metal buildings with quality control and flexibility.

In 2003, Amy Castonguay established JAK Builders and merged together with David Green of JD Builders in 1990. Over the years, our Missouri metal buildings firm has completed thousands of projects.

Philosophy

"The difficult we can do, the impossible just takes a little longer." - Don Lock
We aim and strive to be the absolute best at what we do!

Professionalism

We maintain a consistently high level of professional care and responsibility in each project that we work on and complete. We guarantee all of our work to be of the highest possible quality, as we know our clients would expect nothing less of our team. By hiring us, your project is our project, and we will own it from the beginning to the end.

Creativity

Creativity is achieved through a combination of the architectural collective knowledge of our team, as well as the input obtained through brainstorming sessions with our clients throughout the process.

Style

The completed styles of our buildings are as unique as our clients. With each new client we work with, a new dream becomes reality. Expect a high level of style and class that will not fade with the ages in the final design.

What We Do

​Ultimately our goal as a Missouri metal building supply company is to create high quality buildings, appropriate to what’s needed, in the right settings, while at the same time being extremely functional to whomever or whatever occupies it. We offer a distinct and expansive range of engineering services from planning the structure and program development, through the design and required construction documents, to on-site inspection after completion.
