"John and Cory installed a two level granite rock wall, granite steps and brick walkway to our front door, and it looks fantastic. We were impressed with their hard work and attention to detail. Particularly valuable to us was his background in this type of work which let him recommended design and arrangement ideas for us to consider, and which made the completed project better than we could imagine on our own. John made at least three visits to view the site, discuss options and sent pictures of similar projects. This assured we agreed on what would be done up front so there were no surprises. During the project he daily described what he was doing and the next steps. The granite blocks for the wall were carefully placed for the right look by individually hand splitting, sawing, or grinding for a custom fit. There was extensive work behind the wall to back-fill with stone and even anchor the large end posts with rebar to allow good drainage and stability. This type of detail is impressive since it is all out of sight behind the front blocks and will never be seen, but it will help assure the wall lasts for a long time to come. The same type of attention was given to the positioning, leveling, base preparation and placement of the brick walkway. The project was finished off with a layer of dirt/loam to allow plantings around the hardscape. John and Cory were easy to work with and stuck to the original estimate. Any potential changes were discussed and an estimate provided so we could decide whether or not to include the change. We are 100% satisfied with the outcome of this project. John F."

"We had a water problem with water coming into our finished basement after a heavy rain. S.L. Dionne excavated down to the base of the foundation to fill a crack in the foundation, seal the crack, and cause any water coming near the house to run away from the house. Not only did they do the job perfectly, exactly on schedule, they re-landscaped the disturbed area so my front yard now looks better than before."

"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 Exeter, 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.
