"They are a father and son team. They show up when they say they will. They are hard workers and know what they are doing. My backyard was a disaster, very uneven, full of rocks/boulders and had a really bad slope. I couldn't mow it with my mower. I had to weed wack it. I had them come in and grade,fill and put top soil down. It looks fantastic and is now mow able. They also did a driveway for me. They are very fair with pricing. I highly recommend them."

"Cleaned out and removed over 2000 feet of ditches. Chris communicated well with me. I got my money's worth from this company. Would highly recommend them. Chris also worked for my brother cleaning up farm ditches and installing some culverts. He did an excellent job for him. Glenn & Bill Williams"

"Plumb EZ was an excellent choice for completing my plumbing needs. Daniel was willing to work on a Sunday and also stay after business hours to complete the job. The job was completed in a timely manner with a fair price. I will use Plumb EZ in the future and will recommend others use Plumb EZ as well."

Excavating FAQs, answered by experts

Trenchers can dig holes as narrow as 4 inches or as wide as 4 feet. Check the specifications of the trencher you rent or buy to determine how wide it will cut into the landscape. Better yet, let the excavation company know how wide you’d like the trench to be, and they can help you choose the right trencher for the job (or do it for you).

A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.

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.

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.

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.
