"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 hired Matt to prepare a site for a shed we have ordered. He replied promptly for a request for an estimate. He explained what needed to be done and gave me a fixed date when he could do the work. Throughout the project, he kept me apprised of the progress and explained the choices that needed to be made. I was impressed with the care with which he approached every aspect of the project. Just a great guy to work with."

"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

Excavations take a few days or up to a few weeks. The time it takes to excavate an area depends on the size of the area, the type of soil, the type of excavator, and even the time of year, since winter can make digging up the ground more difficult.

Professional installers often include a deep layer of crushed gravel under permeable pavers to allow more runoff to soak through into the soil below. Many installations will include multiple layers of gravel, with coarser aggregate at the base and finer aggregate that sits on top of that bottom layer. Above the gravel, you’ll often find coarse sand that helps reduce paver shifting over time. Some permeable paver designs include a water collection system set into the gravel layer to route runoff to a safe area for disposal.

Yes, you can excavate in the winter, but it might make the job harder. Frozen ground is harder to dig, and snow or ice can make the work site more hazardous. A contractor may need special equipment and techniques, such as ground-thawing methods, to break through frozen soil. Although winter excavation is possible, it may take longer and be more costly than excavating during warmer months.

Digging a well can cost between $20 and $25,000, depending on your needs. If you’re looking to dig a well yourself, all you need is a shovel. If you’re looking to have a well drilled by a professional, you can expect to pay around $15 to $30 per foot. The total cost of drilling a well will average to $5,500.

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.
