Who We Are & Why Choose Us

Craftsmanship You Can See. Professionalism You Can Feel.

At Site Prep, we believe every long-lasting structure starts with an uncompromising foundation. Founded on Christian values, honesty, and genuine care for people, we don’t just move dirt — we preserve what you build from day one.

From residential shed pads to commercial excavation, we combine cutting-edge technology with old-school work ethic. We respect your time, treat your property like our own, and deliver results that stand the test of time.

Our Purpose

Extending the Lifespan of What You Build

An improper base leads to settling, rotting, and costly damage. Our purpose is simple: build precise, engineered foundations and site prep solutions that protect your investment and extend your structure’s life for decades.

Our Vision

Setting a New Benchmark in Contracting

We envision a contractor experience defined by kindness, punctuality, and zero broken promises. We invest in thriving, OSHA-certified crews and organized job sites where customers feel confident from the first call to final inspection.

Our Standard

Precision Engineering, Not Guesswork

We invest in GPS-guided excavation, digital laser transits, and certified drainage materials. When we grade, level, or pour concrete, it is exact down to the fraction of an inch.

Nick DonatoneExcellent work completing the pad for out shed. Very careful, great communication. We have a narrow road and they placed their equipment in our driveway and move the dump truck up the street so cars, school bus and garbage truck could pass. Then they were able to get the dump truck in the driveway from a different direction. They cleaned up after.Read moreBill LowThe crew notified me in advance of their arrival, always appreciated. Organized, hard working, competent. Respectful of our yard. Excellent job all around. Highly recommended.Read moreLuke WitterSite Prep did a very good job on my new septic system. They were very helpful in helping me decide what system to install, and very responsive to any questions I had. Gid did a great job in sales walking me through the process from start to finish. Ivan was very knowledgeable on the designs and staking out the land and keeping the SEO informed with our progress. And both Ben’s did great work with the installation of the system. They made excellent time and were very professional. Pricing was very competitive even though I was pretty far from their home base. I was impressed.
