About

Construction is more than an occupation, it’s a lifestyle. An entrepreneurial spirit runs heavily in the Jansma family heritage. Starting with Jack’s dad, who owns his own cattle business, all the way down to the up and coming younger generation. So it’s no surprise that Jack chose to start a construction company, following the family pattern of business owners.

Striving to keep close communication, the owner, Jack Jansma, personally supervises the job site. Ensuring that the finished product is high quality, and done the correct way. With over 27 years of experience, you can be confident that Siouxland Construction knows what they’re doing.

Jack and his wife Jody reside in Rock Valley, IA with their two children.
