Customers say: Quick response

"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."

"We hired Christian to remove tree stumps on our property. He gave us a price the next day and started work within a week. His work ethic is incredible—he left the site spotless and communicated clearly every step of the way. Since then, he’s regraded our driveway, removed an old chicken coop, and cleared brush. It’s safe to say Christian is our go-to contractor now."

Excavating questions, answered by experts

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.

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables. 

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.

No, you typically cannot use metal detectors to find your sewer line. Most sewer lines are made of non-metallic materials such as PVC, clay, or cast iron, which are not detectable by standard metal detectors. Metal detectors are designed to locate metallic objects, so they won't be effective for identifying the path of a non-metallic sewer line. To locate your sewer line accurately, it's best to use other methods.

Trenching and boring are two distinct methods for installing underground utilities. Trenching involves digging a channel using equipment like an excavator, trencher, backhoe, or shovel. While it is a simpler process, it causes significant disruption to the surface, landscaping, and surrounding ecosystems.

Boring, also known as directional boring, is a less invasive alternative that uses a drill to create a tunnel for utility lines without disturbing the surface. This method is more precise and is ideal for installations that need to go underneath buildings, roads, or bodies of water. Although boring is less disruptive, it is generally more expensive than trenching.
