Why Are Unions Better?
Union workers are the most highly skilled in the building industry. They uphold a long-standing commitment to bettering their communities. In exchange for this commitment, they receive superior education and training, fair wages, health and welfare benefits and pensions, and the pride of knowing that their skills will remain in
high demand.

It is true that some of our competition can quote a lower price by cutting corners on wages, benefits and training. We believe that it all comes out in the wash. If a worker gets paid less, has lousy health insurance and gets little to no training, it is likely that the owner of the project will get a less than desirable product.

By becoming a union signatory contractor or sub-contractor, employers have the security of knowing their construction project will be completed with superior results – on time and on budget. They also have the pride of knowing they are helping to improve their communities by creating jobs, promoting family stability, and strengthening community involvement. Our Iowa contractors feel a strong responsibility to their customers and their communities. Build your next project with a professional union contractor in our directory.
