In our more than 40 years Sigma Contracting has forged a portfolio of experience and expertise that will be brought to your project to create a smooth and efficient process. With the longevity of our core staff averaging 20 years, and the fact that your project will have hands on ownership from beginning to end, you will have a team that is knowledgeable, capable of problem solving and quick decision making, and that is vested in the success of your project.

The majority of our projects come from repeat clients and referrals. And if we are looking to work with you on your project, it is because we are the right size company to provide the attention it deserves, we are not too small or too big. Too often a large company takes on a small project and it withers, or a small company takes on a project out of it’s reach with disastrous results. We have a defined range in which we excel which results in satisfied customers that continue to call us time and again to bring life to their visions.

Let us put Sigma’s decades of experience and expertise to work for you!

“Let me thank you for opening our eyes to SIGMA and the extraordinarily good job your team does on projects. I could feel the commitment to integrity … and it was obvious you’ve made that a founding principle of your business. Our experiences with you and your team have been some of our best…”
