"They did a great job on multiple area project that included excavation, grading, drainage and septic tank installation. Rick, Brad and Allen were all professional, friendly and real pleasure to work with. Rick was able to perform very precise operations with the excavator and ensured everything was cleaned up and looking good before they left. Would recommend them to anyone in their service area and would consider them for any projects of my own in the future."

"This is a terrific landscaping company. Work included removal of huge ice-damaged shrub, transplanting of an 8-foot tall Burning Bush, total refurbishing of two flower beds and construction of flower bed wood boxes and installation of a split-rail fence. All well-done. Great job with cleanup and disposal of removed shrubs. Bob and his team are very knowledgeable, skilled and easy to work with. They accomplished the Burning Bush transplantation when I wondered if or how it could be done. A top-notch outfit."

"Jeff and his crew did a fantastic job installing a walking path with granite steps to our dock. It’s on very steep terrain and had difficult access. Multiple other contractors passed on the job because of the challenges. Jeff worked two weeks straight and got the job done on time and on budget. Very happy and would absolutely recommend him."

Excavating FAQs, answered by experts

You can bury underground electrical wire six inches deep—but only if you use a rigid metal electrical conduit. For rigid, non-metallic conduits, bury the wire at least 12 inches deep. If using an underground feeder cable rated for direct burial, you'll need to place it at least 18 inches deep, as it has no conduit for extra protection.

The best way to protect tree roots is to avoid the roots entirely by excavating outside the root radius of the tree. For nearby projects, it’s a good idea to construct a temporary retaining wall. But that’s not always possible, depending on the project and the root system. In these cases, consider using alternative equipment like an auger to tunnel under the ground.

Remember, tree roots can damage nearby cement foundations as they grow. If a tree is close enough to interfere with large excavations, it may be better to remove the tree than risk future problems.

You can dig 60 to 80 linear feet by hand per day depending on the depth. Digging a 100-foot trench by hand will take you two work days, but it can take longer if you have heavy or rocky soil. If you’re digging a deep trench or one that’s over 100 feet, consider renting a mechanical trencher, such as a walk-behind or ride-on, or calling a pro for help. 

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).

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.
