Transparent Pricing & Site Requirements

We provide honest, upfront estimates. While we can often give a rough budget over the phone, a final quote requires a site evaluation. Here is what impacts the cost of your project:

Terrain Slope

Is the yard perfectly flat or severely off-level? Steep slope adds grading labor.

Site Access

Can our compact equipment reach the spot easily, or is access tight and restricted?

Hidden Obstacles

Underground utilities, rock formations, or tree roots that must be navigated around.

Size & Shape

Larger areas, L-shapes, or custom dimensions require more material and labor time.

Site Clearing Required

Trees, stumps, or debris that need removal before the area can be prepared.

Material Upgrades

Premium materials, decorative edging, or enhanced drainage add material cost.

What Clients Say About Our Probe & Design

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.

Ben called prior to arrival and was on-time, friendly and professional. After confirming everything they went right to work.

I would recommend them for future work.Read morePhilip OlivieriSite Prep did an amazing job grading my property to setup the absolute best foundation for my new shed.
