"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

Directional drilling is complex and requires training to use the advanced machinery. It can be challenging to monitor the position of the drill since there’s no direct line of sight. Directional drilling can also be more expensive with a cost of $10 to $30 per linear foot compared to $5 to $12 per linear foot for trenching. 

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.

A trench that is less than 5 feet deep often doesn't require a protective system. Most residential trenches will not go this deep (the typical residential drainage trench is just 18 inches deep). In the event that an excavator needs to dig more than 5 feet beneath the surface, a protective system is required unless the excavation is in entirely stable rock.

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 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.
