Kathy coordinated all of the paperwork requirements in a timely way.David and Tyler carefully and skillfully demolished the small barn(there was a building within 2 ft of the barn).

"With their assistance my inland wetlands permit application was approved quickly by my town. The work involved installation of drainage and regrading my entire back yard to bring the lawn back up 14" due to erosion over time. The work was done timely. The extra work included a beautiful new rock wall as well as an excellent exterior basement door entryway. The yard has been reseeded once after the initial seeding and will be reseeded again during the fall. The company takes pride in their work! Pricing was fair as well."

Excavating questions, answered by experts

Underground downspouts refer to the sections of downspout extensions that lead away from your home and gutter system. While they cost more than traditional extensions, they can provide several benefits, such as less frequent damage and no need to move them for lawn care tasks. Whether they're worth it or not depends on your budget at installation time and how much convenience they'll add to your situation.

Completion time ranges from days to weeks, contingent on project size, environmental conditions, and regulatory approvals.

In most areas, you will need a permit for excavation work, even for projects that only involve grading or yard leveling. Permit requirements depend on your local government and the scope of the project, but they are especially common for significant digging or work that could affect utilities or public property. These permits help protect the local topography and prevent drainage issues. An experienced excavation company will typically know whether permits are needed and can often handle the process of pulling and closing them for you. You can also verify permit requirements by contacting your local building department and describing your project.

Sewer lines can be buried anywhere from 18 inches to 8 feet deep, with a common average depth between 18 and 30 inches. The exact depth depends on local factors like climate and soil type. In colder regions, pipes must be buried deeper (below the frost line) to prevent freezing, sometimes as deep as 8 feet. The digging depth can also impact the cost of sewer line replacement. To find the specific depth for your property, you can check the building plans for your system, which should be on file with your city or local sanitation department since permits are required for installation.

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.
