"Eric was right on point and identified the solution and scope of work very promptly. He is a very good communicator via text and in person. I thought his pricing was very fair. He worked to install gutter on my roof, drainage piping, and a trench drain on the side of my driveway to mitigate erosion. He rototilled, fertilized, and installed sod on my formerly eroded front lawn. The work came out fantastic and my neighbors keep complementing me on how nice my house looks now."

"Morton Excavation was GREAT! I asked for 2 estimates, one with a small retaining wall, one without. After receiving the estimates, I contacted Morton and asked how soon could they get started? “Next week, and we should be done in a couple days.” They did have to put me off for one day, but they completed the job in 2 days, cleaned up the work area, and did an excellent job. Thanks!!"

Excavating questions, answered by experts

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.

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.

Yes, professional installations include trenching or borehole drilling required for ground loops.

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.

Sewer lines can be buried anywhere from 18 inches to 8 feet deep, with a common average depth between 18 and 30 inches. The exact depth depends on local factors like climate and soil type. In colder regions, pipes must be buried deeper (below the frost line) to prevent freezing, sometimes as deep as 8 feet. The digging depth can also impact the cost of sewer line replacement. To find the specific depth for your property, you can check the building plans for your system, which should be on file with your city or local sanitation department since permits are required for installation.
