"Mike is terrific to work with. He and his crew are clean, efficient, and reasonably priced. They helped us to backfill and grade a very wet area and build a boulder retaining wall to divert a stream through our woods. The end result is much more attractive and effective at managing the storm water. Mike was helpful in providing guidance and assistance to ensure the project was done right the first time. We would use him again and recommend him to others in a heartbeat."

Excavating FAQs, answered by experts

In the United States, a depth of 36 inches (three feet) for underground water lines is the accepted industry standard. This depth varies from location to location based on local conditions. In areas with colder winters, they may be buried deeper to prevent frozen well water pipes : This is usually at least six inches below the frost level. The International Plumbing Code calls for a minimum of 12 inches below grade.

The time it takes to build a pool—and dig out the area—varies based on the pool size and type. A professional excavator will take between four and eight hours to dig a pool. The process will take longer if they encounter large boulders or tree roots. Keep in mind that this is a small part of the process in the long run. You will need between eight and 12 weeks to build a pool from start to finish, including the time to apply for permits.

The best way to protect tree roots is to avoid the roots entirely by excavating outside the root radius of the tree. For nearby projects, it’s a good idea to construct a temporary retaining wall. But that’s not always possible, depending on the project and the root system. In these cases, consider using alternative equipment like an auger to tunnel under the ground.

Remember, tree roots can damage nearby cement foundations as they grow. If a tree is close enough to interfere with large excavations, it may be better to remove the tree than risk future problems.

The digging depth will depend on the size of the trencher you use. Even smaller units can dig up to 4 feet deep, which is plenty for a DIY job. However, much larger trenchers can reach a depth of 18 feet and are better used by a team of pro contractors, not a single DIYer. As with all home improvement projects, use the right tool for the job and proceed with caution.

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.
