"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

No, you typically cannot use metal detectors to find your sewer line. Most sewer lines are made of non-metallic materials such as PVC, clay, or cast iron, which are not detectable by standard metal detectors. Metal detectors are designed to locate metallic objects, so they won't be effective for identifying the path of a non-metallic sewer line. To locate your sewer line accurately, it's best to use other methods.

Yes, you can excavate in the winter, but it might make the job harder. Frozen ground is harder to dig, and snow or ice can make the work site more hazardous. A contractor may need special equipment and techniques, such as ground-thawing methods, to break through frozen soil. Although winter excavation is possible, it may take longer and be more costly than excavating during warmer months.

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.

It’s possible to transplant trees as tall as 50 feet when an experienced tree planting service uses the right equipment. However, a tree with a trunk larger than two or three inches in diameter needs to be handled by a professional in order to yield successful transplanting results. Consulting a tree planting professional is the best way to tell if your large tree can be safely transplanted.

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.
