"John Welch did a great job installing pervious pavers in driveway as required by local planning board. John took care of all aspects of driveway improvement including obtaining proper permits along with accompanying me at the planning board meeting for approval of the driveway project. John also has a very friendly and hard working crew. Highly recommend JW Landscape"

"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."

FAQs for excavation projects in New Castle, NH

Depth depends on the type of installation and the regulations in your area. Water supply lines typically require 24 inches, while drainage pipes are often installed 36 inches below grade. For most general projects, a depth of 12 to 24 inches and a width of about eight inches is sufficient. Sticking to these specs keeps your utilities safe, code-compliant, and easier to maintain later.

When you need to run utilities underground, you’ve got two main options: boring or trenching. Boring employs directional drilling to install utilities without exposing a continuous channel, while trenching requires excavating an open channel to place utilities securely. Directional drilling preserves landscape integrity, whereas trenching provides direct access for installation, albeit with greater surface disruption. This clear comparison helps you select the method best suited to your project.

Plan on 12 hours to dig 100 linear feet when the soil is cooperative and you can work continuously. This timeframe applies when work is performed consistently and methodically. Factors such as rocky soil, tree roots, obstructions, and frozen ground increase the overall duration, demanding extra planning and effort. Comprehensive operational planning ensures that every challenge is managed efficiently and the project is completed on schedule.

If you want your yard to look untouched, laying fresh sod over the trench is the quickest fix. New sod needs 30 to 45 days to root and blend with the rest of your lawn. A local sod pro can provide you with a firm timeline and tips to ensure the grass takes hold and maintains your curb appeal.
