Why Kolb

More than a grading contractor.

One accountable partner for the whole site. Family-owned for three generations, self-performing every major scope with our own crews and equipment, and mobilized nationwide from the center of the country.

 A letter from our founder 

Welcome to Kolb Grading

If you’re one of our clients, team or stakeholders, thank you for choosing Kolb Grading and supporting our business.

If you’re a new visitor, thank you for taking a few minutes to get to know us and learn more about who we are and what we do. When you leave our website, what I’d like you to take away is a sense of “Wow! I didn’t know you did all of that!”.

Kolb Grading has grown from a small business that provided earthmoving services to one that now provides a host of services in multiple markets for public, private and government entities. We continue to grow using technology to refine our processes, improve our quality, and provide outstanding customer experiences.

We stand behind our word and fulfill our commitments. We provide value engineering, timely completion of projects, and offer the benefit of our experience as a part of the planning process. We’re seasoned business people who understand budgets, the importance of communication, the value of long term relationships, and keeping a sense of humor.

Take a look through these pages and see how we can apply our services to your business. I’d be happy to discuss your next project with you to see if we’d be a good fit. Call me at our office in Weldon Spring, MO or send us a contact request by clicking here.

We’re proud of what our family team has created, and we’d like to be a part of your project.

I appreciate your time and consideration.

Sincerely,

Jeff Kolb
Vice President
