"Luke and Trent are exemplary and knowledgeable professionals. Their quote was very reasonable. They showed up at the exact time and day the promised. These men are courteous and very professional. They had a few obstacles to maneuver around, as they were digging out the hole for the egress window. They did it with great skill and precision. My wife and I are grateful we found this company to do our work. 5 STARS +++"

"Extremely helpful and easy to work with, Hunter listened to all of my wishes and did exactly what I wanted done. He pulled weeds, did some remulching, and overall brought life back to my yard! I will hire him again in the future for upkeep. 10/10 recommend — Hunter seems very genuine and although young, very intelligent and wise."

"SJ&J Excavating and Land Management LLC was hired to regrade/slope existing water problems that would flood back patio and room. They regarded and installed corrugated piping to remove water from the rear yard and allow it to be released naturally in the front yard area. Excellent work and tested after first rain!"

Excavating questions, answered by experts

You can bury underground electrical wire six inches deep—but only if you use a rigid metal electrical conduit. For rigid, non-metallic conduits, bury the wire at least 12 inches deep. If using an underground feeder cable rated for direct burial, you'll need to place it at least 18 inches deep, as it has no conduit for extra protection.

Digging out a basement takes anywhere from a few days to a few months. Most projects take at least two to five weeks, but it could take several months if you encounter obstacles. This project takes longer if you need to brace or raise your home before the excavation. Digging out a basement in new construction can take as little as three days.

There is no standard depth for burying a septic tank; they are typically buried anywhere from 4 inches to 4 feet underground. The final depth depends on several factors, including the depth of your main sewer line, the height of the bedrock, soil type, local regulations, and the property's landscape. If you plan to grow grass or plants over the tank, a depth of at least 4 to 6 inches is recommended. Deeper tanks can be more difficult to locate, but a septic professional can help find it for you.

Sewer lines can be buried anywhere from 18 inches to 8 feet deep, with a common average depth between 18 and 30 inches. The exact depth depends on local factors like climate and soil type. In colder regions, pipes must be buried deeper (below the frost line) to prevent freezing, sometimes as deep as 8 feet. The digging depth can also impact the cost of sewer line replacement. To find the specific depth for your property, you can check the building plans for your system, which should be on file with your city or local sanitation department since permits are required for installation.

Excavation is priced in cubic yards, so you’ll need to find the volume of the area in order to calculate costs. Multiply the length, width, and proposed depth of your excavation site, then convert it into yards to get the volume. Multiply this figure by the price per cubic yard.

Most homeowners can measure by hand to get a rough estimate, even if it’s tedious. You may want to pull out a tape measure or use a string to help mark the area.
