"Second landscaper hired for backyard project after first one messed up quite a few things. TJ and his crew responded quickly and arrived promptly to view what I needed and give a bid. Was given military discount which was a plus to me and work was quality and done on time. Price quoted was price charged. I would recommend them for any project large or small and I will be using them again for some sidewalk installation."

I?m Jared Ponce, and I?ve spent the last 10 years in the field putting in real work and building hands-on experience in excavation and utility services. I specialize in heavy equipment operation, grading, landscaping, concrete repair, sewer repair, clean-out installation, and both water line and well installation and repair.\n\nI take pride in doing the job right the first time?no shortcuts, no excuses. Whether it?s a small repair or a full install, I bring the same level of precision, reliability, and work ethic to every project. This isn?t just what I do?it?s what I know.

Excavating questions, answered by experts

Call 811 to locate and mark the gas lines at least three days before digging. In many areas, you can dig within 18 inches of the lines, though in some locations, the distance may be further. Check local regulations, as you may need a utility company representative onsite when digging. Document your calls to 811 and precautions taken to avoid gas lines. A homeowner can be held liable for hitting a gas line in some cases, but contacting the proper authorities and following all guidelines can offer protection.

Trenches are typically 12 to 24 inches deep and 8 inches wide. However, the required depth depends on the specific project and local ordinances. For example, a French drain may need to be 18 inches deep, while a water pipe might require a depth of 24 inches and a drainage pipe 36 inches. Your city or county may have specific regulations, so it's wise to consult with an excavation professional to determine the correct depth for your project.

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.

A mini excavator can dig between 5 and 11 feet deep, depending on the type and size of the mini excavator. Mini hydraulic excavators are more powerful and can reach deeper into the earth, but electric models have a more limited range. Mini excavators over two tons in size are also more powerful and able to dig as deep as 11 feet.

Digging a well can cost between $20 and $25,000, depending on your needs. If you’re looking to dig a well yourself, all you need is a shovel. If you’re looking to have a well drilled by a professional, you can expect to pay around $15 to $30 per foot. The total cost of drilling a well will average to $5,500.
