"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

This depends on your location. Sewer lines can be buried anywhere from 18 inches to 8 feet deep. People in colder climates will have deeper sewer lines than people in warmer climates due to the dangers of the frost line and freezing pipes. Permits are required for all aspects of septic system installation, so the city should have the building plans for your system, which will tell you how deep your lines are.

There is no standard depth, but typically, septic tanks are buried between 4 inches and 4 feet underneath the earth’s surface. There are a few factors that will determine your tank’s depth, including the height of your bedrock, the distance between your home and the tank, and the depth of your main sewer line.

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.

Yes, you can install a trench drain if you already have concrete in your yard or garden. While it can complicate some aspects of the job and slightly run up the cost, it is doable. Residential trench drains can be easily retrofitted to outdoor areas with concrete without having to remove excessive amounts of your patio, pool area, or decorative walkways.

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.
