"Ron arrived on time and removed the propane tank on my balcony. I was very grateful for the service because the tank was in a grill and the company taking the grill would not take the propane tank. Ron was very personable and efficient. It was great to see the propane tank go."

"Rodrigo & team have been providing gardening services for me for a decade now, on a relatively small scale. I'd hired a residential designer to craft a design for a backyard living space, and Rodrigo was my first thought for putting it into action. The team excavated/leveled the space for a flagstone patio and a to-be-installed gazebo. So much care was taken to prep the space, make the ground level, and follow the measurements. They laid the flagstone beautifully. They also built a retaining wall, providing some much-needed planting space. Finally, they laid down new grass, weed-blocker, and wood chips, providing the foundation for me to go crazy at nurseries this summer. I have a few friends who are very experienced with construction, etc., and they all have made special note of how the quality of this work. Note: this was NOT an easy feat from a labor, as 3-4 tons of materials had to be hauled by hand/wheelbarrow from my driveway to the back. I appreciate that they're still talking to me!"

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.
