"The team helped us through one of the worst situations. Our home was severely damaged and flooded by Superstorm Sandy. We needed someone to help secure the existing structure, help oversee the insurance process and do the rebuild and remodel. We were very appreciative of the diligent work of this firm. They helped create a better design to prevent future flood risks, remodeled the house in full, and did it within our budget with insurance. In the beginning there were many nights where the team pulled all nighters."

Excavating questions, answered by experts

You should dig 3 to 6 inches deep for plastic edging. Dig as wide as you need to fit your plastic edging into it—2 inches is usually sufficient.

The completion timeline for an in-ground swimming pool project typically ranges between 8 to 12 weeks, depending on weather conditions, the complexity of the design, and any unexpected ground conditions encountered during excavation.

It takes two to three hours to trench 100 feet with a mechanical trencher or 10 to 12 hours if digging with a shovel. The total time to dig a trench depends on the depth, width, soil type, terrain, trencher type, and your level of experience. Digging in clay or rocky soil takes longer than soft ground.  

Completion time ranges from days to weeks, contingent on project size, environmental conditions, and regulatory approvals.

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.
