"I really appreciated the great excavation and fill work that Roland Gagnon did for me. This was a driveway drainage project that required low spot filling and proper grading of the area. The driveway now has the proper slope and is draining properly. Roland went above and beyond my expectations, he will be my first call for any future work."

"I posted on Angi and Matt responded immediately and was friendly and professional. He made an access entry from the original basement wall into my addition. There was little to no cleanup for me after! Job well done to Matt and Dickie. I highly recommend Smithtown Landworks."

"We hired Waterscapes when our initial contractor abandoned the project and took our money, and they did a great job.  They were very communicative and sent regular status updates to us which we appreciated since we lived out of state.  Additionally, they finished the project in 10 days which was really impressive considering that they had to basically start from scratch  They also had competitive prices and cost-effective solutions to problems that satisfied all of our neighbors' concerns."

Excavating questions, answered by experts

Water lines are buried at various depths, depending on the type of line. For example, most sprinkler lines are buried between four and 12 inches underground. On the other hand, water mains usually sit between one and 3 feet below ground. However, they can go even deeper in cold climates to prevent freezing.

Trenches are typically 12 to 24 inches deep and 8 inches wide. However, the required depth depends on the specific project and local ordinances. For example, a French drain may need to be 18 inches deep, while a water pipe might require a depth of 24 inches and a drainage pipe 36 inches. Your city or county may have specific regulations, so it's wise to consult with an excavation professional to determine the correct depth for your project.

We recommend removing the stump, and grinding is a popular way to do it. You can also dig out small stumps or stumps that have fully decayed instead of grinding them. However, don’t try using acids or fire for killing a tree stump, which is a fire hazard and illegal in many areas.

Leaving the stump alone invites eventual problems, including attracting termites, mold, and fungi.

A walk-behind trencher can cut through roots as long as they’re not too thick, making a project much easier than digging with a shovel and other hand tools. Assess your terrain and the number of trees in the surrounding area to determine if a walk-behind trencher will ease the job. Digging a trench by hand is much more time-consuming and labor-intensive. 

To locate an underground downspout, you should start by identifying where the above ground gutter drains. Look for an entry point, such as a pipe or elbow leading into the ground. Follow the surface path for signs like depressions, landscaping disruptions, or wet areas after rain. You can use a metal detector or plumber’s snake to trace the pipe underground. For deeper pipes, a professional locator tool or camera inspection may be necessary. Visual markers or utility maps can also guide the search.
