"Daniel was awesome to work with. He came out and provided a solid estimate in a timely fashion. We had an unexpected sprinkler line that was in the middle of our excavation area and he took care of that. He also provided the materials for a retaining wall that we hadn't initially planned for, and he added that to the project scope without issue. I will definitely reach out to Daniel if we have another project like this one."

Excavating questions, answered by experts

A perc test can take anywhere from one to eight hours to complete. The total time depends on factors like the amount of excavation required, the depth and width of the holes, and whether multiple test holes are needed. For a single hole, the process of filling it with water and monitoring the drainage rate usually takes less than an hour. Professionals can often complete the entire test in a single day. While it's possible to get results the same day, some companies may take a few days to provide the official report.

It takes one hour to dig a 10-foot trench by hand. Use a trenching shovel with a sharp tip and a long head. Plan for more time if your soil is heavy or rocky. Consider renting a trencher if you’re digging a long or deep trench or if you have challenging soil or terrain. 

The rules and regulations regarding groundwater use vary between states. To find out if you can dig a well on your property, you’ll have to consult these regulations, address any compliance requirements, and get the appropriate permits. It’s also important to check that your intended location has the right geology and water table to support a well.

You can dig 60 to 80 linear feet by hand per day depending on the depth. Digging a 100-foot trench by hand will take you two work days, but it can take longer if you have heavy or rocky soil. If you’re digging a deep trench or one that’s over 100 feet, consider renting a mechanical trencher, such as a walk-behind or ride-on, or calling a pro for help. 

Slab foundations are more affordable than crawl spaces because they require minimal excavation, as the slab sits directly on the ground or on footers that only sink a few feet into the ground. Crawl spaces require excavation of the entire footprint of the home to several feet below the surface. Not only does that mean higher labor costs, but more materials are necessary for the concrete foundation walls.
