"The attention to detail of the work was top rate. We had three sink holes in our yard that they took care of for us, as well as spreading loam for us to start a lawn in the spring. I very highly recommend McAdams Excavation."

"We just moved into our home and wanted to get our backyard graded. Kyle came by right after I talked with him and gave us a great quote. He had his crew there shortly after. He frequently checked in while the project was going on, and addressed any questions and concerns I had. Tony did a fantastic job with the grading, and was extremely knowledgeable and professional. After this we were so pleased that we had them also spread loom and put in some steps. Leo did a great job spreading and smoothing out the loom. All had great work ethic, and it was obvious they knew what they were doing. After the job was done they still checked in to make sure everything was good, and anytime I had a question they were quick to respond. Would highly recommend K&J. 5 stars!"

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.

A trench that is less than 5 feet deep often doesn't require a protective system. Most residential trenches will not go this deep (the typical residential drainage trench is just 18 inches deep). In the event that an excavator needs to dig more than 5 feet beneath the surface, a protective system is required unless the excavation is in entirely stable rock.

To locate an underground downspout, you should start by identifying where the above ground gutter drains. Look for an entry point, such as a pipe or elbow leading into the ground. Follow the surface path for signs like depressions, landscaping disruptions, or wet areas after rain. You can use a metal detector or plumber’s snake to trace the pipe underground. For deeper pipes, a professional locator tool or camera inspection may be necessary. Visual markers or utility maps can also guide the search.

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

Preparation involves site assessment, clearing debris, grading surfaces, and compacting soil to support stable construction.
