Who We Are

Nixcavating has been providing quality excavation, demolition, underground utility, and site preparation and grading services along the Colorado Front Range since 1982. We have the capabilities to handle all your civil construction needs, from the project layout to the final grading.

We have worked on projects throughout Colorado over the years, but are grateful for the booming local economy, so have chosen to stick to work closer to home. We have job sites all over Boulder County, from our home in Longmont, to Erie, Niwot, Lafayette, Louisville, and of course, Boulder. We also regularly work in south Larimer County, such as Berthoud and Loveland, and in Western Weld County areas like Frederick, Firestone, and Dacono. Just because we didn’t mention your town, doesn’t mean we won’t work there, give us a call and we’d be happy to discuss your project and our availability with you.

“I have dealt with Nixcavating several times on different jobs around my small farm. I hesitate to write a great review simply because I want to keep them to myself! But they deserve the best review I can give, so 10 stars to these fine folks. They are attentive, fair, thorough, honest, and they always make sure that I am 100% satisfied before they finish. You will not find another company of this type that is better than Nixcavating.”
