"Had a retaining wall done? Eric was great in keeping me informed of all steps up to the very end and was easy to work with. His team did an outstanding job and the wall looks great. It is nice to have a company that shows pride in its work and cares about the customer. I highly recommend them."

"Cavallero Earthworks came to our home when he said he would be here. He sat and listened as we explained our problem. He took charge: filled out forms, contacted the proper county agency, gave us a bid amount and my husband and I just sat there in the kitchen after he left awestruck by the proficiency and speed in which Ben handled everything. He took time out of his busy schedule and was in constant contact with us, keeping us informed of where we were in the process. He stayed focussed on the task and completed it quickly and efficiently. Professional, good communicator, proficient on the equipment, knowledgeable in his line of business, and just a really nice person! My husband and I appreciate Cavallaro Eartworks and wish them the best."

"Working with Mid-Valley Excavation was an excellent experience. They took the time to come out and give a thorough bid inspection. They spent a good amount of time talking to us, listening to our wishes and needs and discussing project scope and requirements. They delivered a bid quickly and they were very responsive to follow-up questions and concerns. Their work is great, the end result was above and beyond my expectations. They were quick, efficient, and work with an attention to detail. It was a pleasure working with them. I would hire them again for future projects."

"They were a couple weeks out when we hired them, we went in a hurry so it worked. They were to start on a Monday and pour the following Friday. When they arrived they said we have concrete coming later today. The crew got it dug II, removing the stump, adding rebar, gravel and cement was down by 3:00 same day. We were happy. They came back today to strip the forms do a final cleanup. We are having them look at another project too. 5 stars."

"Quick response with a bid. Showed up when promised and were very professional and courteous. Driveway and patio pressure washed and sealed to look like new. We couldn’t be happier with result. Would definitely hire Roli and team again."

Excavating FAQs, answered by experts

If you’re planning to dig on your property, you’ll need to check for underground utility lines. Call the national call-before-you-dig 811 number. Once connected to an operator, you can schedule a site visit to mark underground lines. This way, you won’t accidentally dig into pipes and can cause major (read: costly) issues.

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.

A trench that is less than 5 feet deep often doesn't require a protective system. Most residential trenches will not go this deep (the typical residential drainage trench is just 18 inches deep). In the event that an excavator needs to dig more than 5 feet beneath the surface, a protective system is required unless the excavation is in entirely stable rock.

Completion time ranges from days to weeks, contingent on project size, environmental conditions, and regulatory approvals.

The average cost for pool excavation is $2,500. This cost can range from $450 to $4,500, depending on the pool shape and size, time of year, and any need to move buried utilities. 

When excavating for your pool, you might have to move existing utilities. You can expect to pay an additional $15 to $25 per linear foot to move gas lines. To move a septic system, it’ll cost an additional $2,000 to $20,000. A pool that is 10 feet by 12 feet averages $450 to excavate, and a 20-foot-by-40-foot pool averages $3,020.
