"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."

"Jake and his team were awesome to work with and they'd be the first I'd recommend for any excavation job big or small. He was able to make our vision for a backyard into a reality and worked tirelessly (weekends included) to make it happen. Jake was on time, honest and dependable, which is unheard of in the current market!"

"Eric was great. He did a large brush clearance around the house and graded the land and put in loam and seed. Great communication and a fair price for the work. Would highly recommend!"

Excavating FAQs, answered by experts

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.

Trenches are typically 12 to 24 inches deep and 8 inches wide. However, the required depth depends on the specific project and local ordinances. For example, a French drain may need to be 18 inches deep, while a water pipe might require a depth of 24 inches and a drainage pipe 36 inches. Your city or county may have specific regulations, so it's wise to consult with an excavation professional to determine the correct depth for your project.

Slab foundations are more affordable than crawl spaces because they require minimal excavation, as the slab sits directly on the ground or on footers that only sink a few feet into the ground. Crawl spaces require excavation of the entire footprint of the home to several feet below the surface. Not only does that mean higher labor costs, but more materials are necessary for the concrete foundation walls.

Some two-in-one tools and machines do both jobs, and those could be the right solution for smaller residential projects. However, the phrase “use the right tool for the job” definitely applies to digging. For the best results, get two separate tools for your trenching and landscape edging projects or call a pro to take care of everything for you.

Downspouts should be buried at least 5 to 10 feet away from your foundation. This can vary depending on your local building codes, soil type, and property slope. The main goal is to ensure water is directed away from your foundation.
