"Dj and the team at Roberts construction did a fantastic job building a detached garage at my house from start to finish. His team handled everything from designing and drafting the prints, pulling permits, excavation, and building. If you?re looking for a reliable contractor at a great fair price, Robert?s construction can handle the job."

"We had a little issue - did not ask a lot of questions or do a visual inspection before snaking our shower drain - turns out we should not have done that due to this drum trap we had. Long story short ending up breaking a pipe - but it was all so old we needed to get it replaced anyway. I had to fight for what I thought was right, but at the end of the day they took care of the price and the situation. Overall this company is probably too expensive for their quality of services, but they were very kind and worked hard to fix this situation."

"Matt Hazelwood was very prompt in returning my call & he came to my house immediately to asses our situation. He was very honest & polite. I had a family member who could do the work, that is why I didn't hire him. however if I didn't have a family member, I definitely would have hired Matt Hazelwood. He would have done a completely thorough job."

FAQs for excavation projects in Cobalt, CT

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.
