"Easton was great to work with and we would highly recommend him! He built our road and a campsite area next to our house, and then we hired him again to do our pad for our barn and an arena. He was always on time, professional, and did work that has held up well. We will definitely hire him again if we need another project, especially because his prices were great. 10/10 recommend"

"Absolutely Outstanding Service! I hired Lane to handle trucking and dirt work to prep my yard for landscaping, and he went above and beyond in every way. From start to finish, his professionalism, efficiency, and attention to detail was impressive. He didn?t just get the job done?he made sure it was done right. The crew was punctual, courteous, and clearly experienced. They tackled tough terrain, ensured proper grading, and even cleaned up better than expected. What really stood out was how proactive they were? offering helpful suggestions and making improvements I had not even thought of. It is rare these days to find a company that takes this much pride in their work. I am beyond pleased with the results and would not hesitate to recommend them to anyone needing dirt work or site prep. Thanks again for exceeding expectations!"

"Their work was excellent. I liked the text messaging and voice contacts that kept me up to date on the process. They removed a tall (dead) Aspen right next to my house and brought in the proper equipment to make sure everything went smoothly. I thought price/performance was first rate. The only reason I didn't give them straight 5.0s is a slight delay (unavoidable on their part) that I wasn't kept up to date on. I highly recommend them."

Excavating FAQs, answered by experts

In the United States, a depth of 36 inches (three feet) for underground water lines is the accepted industry standard. This depth varies from location to location based on local conditions. In areas with colder winters, they may be buried deeper to prevent frozen well water pipes : This is usually at least six inches below the frost level. The International Plumbing Code calls for a minimum of 12 inches below grade.

Prior to excavation, you should prepare the dig site and call 311 before you sign anything.

To get your site ready for excavation, you should move anything in the area that isn’t affixed to the land. You can save money on the excavation by removing hardscaping, including walkways, decks, concrete patios, and paver patios.

Before you carry out any digging, you should call 311 to confirm that there are no utility lines running through your excavation site. Skipping this step could lead to severe injury and property damage if your excavator hits a water, sewage, or gas line.

Concrete blocks are the cheapest way to base a shed. However, the space in between allows critters to go under, burrow, and even damage your shed’s frame. For a more pest-proof option, consider building a shed base with gravel or paver stones. Both options are fairly affordable and easy enough for a DIY project. For gravel, you can build a wooden frame to contain the loose material.

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.

You should dig 3 to 6 inches deep for plastic edging. Dig as wide as you need to fit your plastic edging into it—2 inches is usually sufficient.
