Demolition and Deconstruction

Nixcavating has the equipment and experience to safely and efficiently remove any unwanted structures, buildings, landscaping, or walkways and driveways from your project. Whether your needs are a "blank canvas" site, or just removing a few select features, we can take care of it. We are also able to facilitate any environmental abatement your site may need, along with dump services, recycling and other "green" efforts.

Excavation and Site Preparation

We all know a solid foundation is the most important part of any project. Without properly compacted soil or appropriate sloping and water runoff mitigation, natural settling or weather elements can ruin property and structures. Our experiences with the many different types of soils throughout Colorado help us to ensure we are able to give you a sturdy base to build upon.  Whether needs are a road "rehab", precise grading for a building pad, or excavating for a basement under your existing home – we are able to provide the equipment and skills to complete the work safely and efficiently.

Underground Utilities

Nixcavating is proud to specialize in all types of underground utility work, and we pride ourselves on being knowledgeable and efficient while in the trench. Our experience with the installation, repair and replacement of utility service lines will ensure you get the job done correctly. You can trust our judgment and decades of experience when discussing the plan of action to solve your problem.

Concrete and Asphalt

As an excavation contractor that concentrates on work below ground, we've become very experienced at patching back the concrete and asphalt above our work area. Our patching and paving services are not our focus, but as a company with an experienced crew in our industry, we're able to handle most projects.


Nixcavating has a dedicated fleet of single axle and tandem axle dump trucks, as well as trucks and a side dump trailer capable of hauling large quantities of aggregate materials. We are able to haul-in and haul-off any materials you wish, including water. Our water trucks can be utilized for dust control, or watering of landscape and trees during periods of no rain.

Storm Water & Irrigation

Water has a mind of its own, and without manmade structures and engineered water distribution plans, it is capable of wrecking havoc. Whether you live in an area with a high water table and you've got flooding concerns, or your land is washing away with each rainstorm – Nixcavating is able to aid with solutions.

Snow Removal

Nixcavating has been pushing snow for commercial clients in Longmont for over thirty-five years. Our fleet of plow trucks, front-end loaders, blades or motor graders, skidsteers and dump trucks allow us to move snow quickly, and our crew of experienced operators helps to make sure it gets done well.
