Excavating questions, answered by experts

The cost to dig a trench ranges from $400 to $1,200 per 100 linear feet, depending on the soil, depth, and width. Plan to spend $5 to $12 per linear foot for trenching (it’ll be on the higher end if you have rocky soil). Renting a trencher costs $100 to $250 per hour, depending on the type of trencher. 

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.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.

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.

Trenching is not the same as boring. Boring uses a drill to make a tunnel for underground utilities, but trenching involves digging with an excavator, trencher, backhoe, or shovel. Boring is more precise and expensive, and it’s best for installing utilities underneath buildings, roads, and bodies of water. Trenching is simpler but can cause more disruption to landscaping and ecosystems.
