"Jared did an amazing job and was very thorough in his work. He prepared the site work for a retaining wall behind a newly installed pool and the attention to details in where he placed the drainage was perfect. The following week we had a tremendous amount of rain and it kept all that water well away from the pool. Took a lot of pride in the work he did for us and can not wait to work with him again on our next project!"

Excavating questions, answered by experts

Downspouts should be buried at least 5 to 10 feet away from your foundation. This can vary depending on your local building codes, soil type, and property slope. The main goal is to ensure water is directed away from your foundation.

Some two-in-one tools and machines do both jobs, and those could be the right solution for smaller residential projects. However, the phrase “use the right tool for the job” definitely applies to digging. For the best results, get two separate tools for your trenching and landscape edging projects or call a pro to take care of everything for you.

In most areas, you will need a permit for excavation work, even for projects that only involve grading or yard leveling. Permit requirements depend on your local government and the scope of the project, but they are especially common for significant digging or work that could affect utilities or public property. These permits help protect the local topography and prevent drainage issues. An experienced excavation company will typically know whether permits are needed and can often handle the process of pulling and closing them for you. You can also verify permit requirements by contacting your local building department and describing your project.

There is no standard depth for burying a septic tank; they are typically buried anywhere from 4 inches to 4 feet underground. The final depth depends on several factors, including the depth of your main sewer line, the height of the bedrock, soil type, local regulations, and the property's landscape. If you plan to grow grass or plants over the tank, a depth of at least 4 to 6 inches is recommended. Deeper tanks can be more difficult to locate, but a septic professional can help find it for you.

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.
