"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 FAQs, answered by experts

Underground downspouts refer to the sections of downspout extensions that lead away from your home and gutter system. While they cost more than traditional extensions, they can provide several benefits, such as less frequent damage and no need to move them for lawn care tasks. Whether they're worth it or not depends on your budget at installation time and how much convenience they'll add to your situation.

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.

Water lines are buried at various depths, depending on the type of line. For example, most sprinkler lines are buried between four and 12 inches underground. On the other hand, water mains usually sit between one and 3 feet below ground. However, they can go even deeper in cold climates to prevent freezing.

A mini excavator can dig between 5 and 11 feet deep, depending on the type and size of the mini excavator. Mini hydraulic excavators are more powerful and can reach deeper into the earth, but electric models have a more limited range. Mini excavators over two tons in size are also more powerful and able to dig as deep as 11 feet.

Yes, chipmunk holes may have two or more entrances. Chipmunks can create an entire network of burrows. Having multiple entrances makes it easier for them when trying to escape from a predator, such as a snake, or if an entrance collapses due to flooding. Each entrance leads to the nesting chamber underground, which is where the chipmunk spends the majority of its time sleeping.
