"Toby cleared 50 years of deadfall branches and established a driveway on a 1/4 acre lot in one day. Amazing. Brought him back for stump removal, grading and to establish a surface drain. Artist with an excavator. Perfect grade and solved erosion and drainage problems. Worked with B.C.X. gravel and prepared a perfect pad and safe driveway for our trailer. I trust him for anything else I need in the future. Reasonable rates. Doesn't waste your time. Extremely responsive to short notice schedule changes. A joy to work with someone so professional."

"The project was demolition of an old swimming pool to code and filling it in with dirt. Ray is a hard-worker, never complained about the 100+ degree weather, reliable, finished the project in the amount of time proposed, gave a fair price and made my life easy. Project required extra (unforeseen) equipment and he actually split the extra cost with us instead of making us pay the full extra amount. Would use him again and recommend him."

Excavating FAQs, answered by experts

No, a ditch isn’t a trench. A ditch is an open, relatively shallow channel that’s carved out of the ground and used for drainage purposes. In contrast, a trench is a deeper excavation that’s entirely underground. Trenches have many uses, including gas lines, sewage systems, and electrical wiring. Unlike trenches, ditches don’t get filled back in with dirt after they’re dug.

Tree experts don’t advise against digging through tree roots, but instead encourage caution and consultation with a local arborist to make sure you don’t damage the tree’s structure or interrupt its water or nutrient intake. An arborist can recommend specific practices when digging and help prune the roots or dig a trench for utilities with a tool that can remove soil without touching the tree’s roots.

It takes one hour to dig a 10-foot trench by hand. Use a trenching shovel with a sharp tip and a long head. Plan for more time if your soil is heavy or rocky. Consider renting a trencher if you’re digging a long or deep trench or if you have challenging soil or terrain. 

Yes. A metal detector is one of the quickest and easiest ways to find your septic tank. However, metal detectors can be too expensive (costing upward of $300 in some cases), and not everyone has a metal detector just lying around. If that’s the case for you, you can also take a long metal rod and poke it into the ground at regular intervals until you hit something—likely your septic tank lid.

Yes, an excavation company is the best option for land grading and yard leveling. General landscapers might be able to tackle these projects, but an excavation company will do a better job because they’re used to operating the necessary heavy machinery. Landscapers might opt to do the work manually, which takes much longer and could cost you more in labor fees. Finally, excavation companies will understand local regulations and know when you need permits to legalize the work, while a landscaper might not.
