They came out the next morning, when they said they would, and did the job quickly and efficiently. Their technician was very friendly and a pleasure to work with. I would hire them again in a minute!"

"I am so impressed and pleased with the quality, integrity, and professionalism Rob Capella of Capella Enterprise Landscape Design and Development stands for. This gentleman has the heart of a teacher, along with a love of creating something functional and beautiful. He explained every step of the way what was needed for our retaining wall, and how a retaining wall functions; grading, drainage, equipment needed, etc. The gentleman in his crew worked tirelessly. He went above and beyond to work with us, especially since in digging they hit shale, which was a complete headache for them, and meant the job would take longer. Yes, it did mean that the job would cost more because you can't build a wall on shale, but Rob had thoroughly discussed with us ahead of time that you never know what you are going to find when you dig so we were definitely OK with having to deal with that. He also did what he could to make it work on both ends, and we are eternally grateful to him for that!"

FAQs for excavation projects in Harriman, NY

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.
