"Replaced leech field- he did an excellent job removing my old leech field and replacing it with a better system. From the time I entered the job in homeadvisor (approx 8am) I was called back before noon. We scheduled a site review later that day. From the time I selected Roadway, there was constant progress. Even when the permits were in progress, they were in constant contact to let me know what was going on. When the permits were in order, they worked nonstop until the job was done. Their work was excellent, prompt and neat. Highly recommend."

Excavating questions, answered by experts

Trenches are typically 12 inches to 24 inches deep and 8 inches wide. However, your city or county may have specific ordinances that clarify the dimensions needed for the project. For instance, a water pipe may need to be 24 inches deep, but a drainage pipe may need to be 36 inches deep.

Digging a bush up by the roots is the most natural DIY method for removing a bush stump. Start by identifying the shrub type and revealing its roots. Cut the shrub to its base and loosen the soil, ensuring no utility lines are nearby. Optionally, treat the base with herbicide, then dig around the roots and cut a circle around the shrub using various tools. Dig a trench, cut the base of the root ball, and finally fill the hole to prevent regrowth. This thorough process ensures complete removal without damaging surrounding areas.

Landscape edging is more DIYable than trenching. You can DIY your own digging projects, but proceed carefully and only with proper knowledge of the equipment and appropriate safety measures in place. Keep in mind the project's scope and estimate how long it will take you to do it on your own. While you can certainly save money by DIYing home improvement projects, you can’t exactly hide an unfinished—or worse, ruined— landscaping job from the neighbors. It’s always safer to call an excavation pro near you to get an estimate.

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

The physical constraints of hand-drilling a well limit the depth you can achieve. Manually digging with picks and shovels may only lead to shallow wells of up to 60 feet in depth. To reach greater depths, you need more specialized equipment. The diameter of your well and the tools you’re using will determine how far down you can dig.
