About

Born and raised in Idaho, Jake Fillmore first began building steel structures in high school for his father’s company, then called Fillmore Custom Builders. The company’s work ranged from dairies and barns, airplane hangars, shops, and storage facilities to custom homes, remodels and everything in between. Jake took the company over when his father retired. With over 30 years of experience, JMF has become very specialized in steel construction of all project sizes.

Chances are that we not only can build your structure, but we have built many like it already. JMF puts up quality buildings, aims for excellence in craftsmanship, and just does things the right way in general. With literal decades of experience, it is rare for much to surprise us. We’ve done projects all over the Treasure Valley and beyond for businesses such as Simplot Western Stockmen’s, CSDI, Champion Produce in Parma, and Farm Equipment USA in Fruitland and Jerome. Have a small project? You’ve come to the right place. We build smaller projects regularly, not just the large scale ones. Head over to our Frequently Asked Questions section to learn more about the process. If you still have questions, please call us. We truly want to be as helpful as possible.
