Our Story Dirt work done right,
Our Full Story
Dirt work done right,
since day one
Onsite Construction is a woman-owned excavation and site work company serving East Tennessee since 2018. Nikki and Wyatt built this business together as a team, combining their strengths to handle every job from the first phone call to the final grade. What started as a two-person operation has grown into a trusted name across multiple counties in the region.
With over 40 years of combined experience in dirt work and site development, we bring serious field knowledge to every project. We have worked on everything from small residential lots to large commercial sites. That depth of experience means we can read a job site quickly, plan the right approach, and get the work done without surprises.
How We Work
How We Work
From your first call to final cleanup, we handle every step of your excavation, septic, or dirt work project. Our process is straightforward so you know what to expect.
Call for Your Estimate
Contact us at +14238954848 or email [email protected] to describe your project. We'll ask about your site, scope of work, and timeline so we can give you an accurate quote.
Site Assessment & Plan
We visit your property to evaluate the land, drainage, soil conditions, and any obstacles. This helps us determine the right equipment and approach for your job.
Work & Regular Updates
Our crew performs the excavation, grading, septic install, hauling, or other dirt work you've approved. We keep the site organized and communicate progress as we go.
Completion & Cleanup
Once the work is finished, we remove debris, grade the site as needed, and leave your property ready. We're available for any follow-up repairs or adjustments you may need.
We work Monday through Friday, 8 a.m. to 5 p.m. We manage site logistics and equipment placement—you approve the plan before we start.
