FAQ
Frequently asked questions
What types of underground utilities do you work on?
Our focus is water, sewer, and storm infrastructure — including water service lines, sewer laterals, storm drain systems, sump systems, and related underground utility work and excavation.
Do you handle both installation and repair?
Yes. We install new underground utilities and replace or repair existing ones. The right approach depends on the condition of the line and the goals of the project, which we review with you.
Do you work on residential and commercial projects?
Both. We work with homeowners, property managers, HOAs, businesses, developers, and general contractors on projects ranging from a single service line to larger commercial utility work.
Do you provide emergency repair service?
We offer emergency repair service for qualifying water, sewer, and underground utility issues. Call (310) 713-6492 to describe the situation and we’ll let you know how we can help.

Can you help me understand whether a line needs repair or replacement?
That’s a big part of what we do. We look at the situation, explain what we’re seeing, and walk you through the practical options so you can make an informed decision.
Do underground utility projects require permits?
Many do. Requirements vary by jurisdiction and scope of work. We’ll identify the applicable permit and inspection requirements as part of planning your project.
Can you work with plans for commercial projects?
Yes. Commercial clients can upload plans and documents through our commercial inquiry form so we can review the scope before discussing the project.
