"This was a complex project with a lot of moving parts.
Several thousand square feet of patio, complicated pool coping and a significant amount of reconstruction. The land I gave Carl to work with was ugly and unstable.
I give Carl an A for time and price because of the value he brings to the table. Not because he's the cheapest or the fastest sprinter.
Some significant challenges materialized over the course of the job that added time and cost to the project. The great thing is Carl rolled with the punches, reacted fast, didn't compromise quality, and never asked for more money.
This was not an easy piece of land to work with. A 40 year old pool patio on shaky foundations.
His foreman/mason Eddie is the only person I trust to do anymore work on my hardscape/landscape. His ability, attention to detail and work ethic is unquestionable.
Carl brings 30 years of experience to the table; great design ideas, flexibility, problem solving, vision..........value!!
Additionally, Carl has a fantastic network of partners that are just as reliable.
I would be happy to provide a reference to all serious buyers.

FAQs for excavation projects in Dover, 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.
