"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."

"Mr. Carideo did a great job on my small project. He tried to save me money on the materials by using a different thickness of wood. I ultimately decided to not go with his recommemdation. But I was very happy that he consulted me first and that he was trying to save me money. He handled the project in a reasonable amount of time. Actually sooner than I thought because it was around Christmas and New Years. His fee was in line with other estimates. I would use his services again."

Excavating FAQs, answered by experts

Downspouts should be buried at least 5 to 10 feet away from your foundation. This can vary depending on your local building codes, soil type, and property slope. The main goal is to ensure water is directed away from your foundation.

Prior to excavation, you should prepare the dig site and call 311 before you sign anything.

To get your site ready for excavation, you should move anything in the area that isn’t affixed to the land. You can save money on the excavation by removing hardscaping, including walkways, decks, concrete patios, and paver patios.

Before you carry out any digging, you should call 311 to confirm that there are no utility lines running through your excavation site. Skipping this step could lead to severe injury and property damage if your excavator hits a water, sewage, or gas line.

Whether you grind or dig up and remove your tree stump depends on your landscaping goals. Using a stump grinder leaves the root system in place for it to decompose over time, whereas digging up the tree stump removes the roots and the stump. Overall, stump grinding is a far simpler process since you won’t need to deal with the roots. Stump removal will make your yard look like a demolition site, but you’ll have an easier time replanting in the same place as your former tree.

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.

Slab foundations are more affordable than crawl spaces because they require minimal excavation, as the slab sits directly on the ground or on footers that only sink a few feet into the ground. Crawl spaces require excavation of the entire footprint of the home to several feet below the surface. Not only does that mean higher labor costs, but more materials are necessary for the concrete foundation walls.
