"Giovani and Dell of Ultra Construction were great to work with and they responded quickly and efficiently to our contractor inquiry. They came out the next day and provided a fair and reasonable estimate. Dell and his crew, including Julian came out and had the concrete walkway and stairs installed in just one day. It looks great and we couldn’t be happier with the results. Their prep work and cleanup were outstanding. Would highly recommend this company for any concrete construction work"

"He was available by phone, and was flexible in scheduling meetings which is great. He was professional, and seemed quite knowledgable. In the end, I didn't use Nato's services because his quote was twice as much as the other contractor I was considering. Perhaps his prices may be more competitive in other services he offers. Either way, working with this company was a pleasant experience."

"Miguel completely re-configured our plumbing under the house a few years ago and we have never had issues again. He diagnosed the issue accurately and was able to complete the job quickly and at the highest level of quality. His knowledge of virtually all mechanical and structural aspects of renovation/repair are second to none. I would recommend him without hesitation to anyone and with highest confidence."

Excavating questions, answered by experts

In most areas, you will need a permit for excavation work, even for projects that only involve grading or yard leveling. Permit requirements depend on your local government and the scope of the project, but they are especially common for significant digging or work that could affect utilities or public property. These permits help protect the local topography and prevent drainage issues. An experienced excavation company will typically know whether permits are needed and can often handle the process of pulling and closing them for you. You can also verify permit requirements by contacting your local building department and describing your project.

In the United States, a depth of 36 inches (three feet) for underground water lines is the accepted industry standard. This depth varies from location to location based on local conditions. In areas with colder winters, they may be buried deeper to prevent frozen well water pipes : This is usually at least six inches below the frost level. The International Plumbing Code calls for a minimum of 12 inches below grade.

The easier way to find buried sprinkler lines is to use the plan from the professionals who installed the system. If you don’t have professional plans, listen for running water on your lawn when you turn on the system. You may also spot wet areas, giving you an idea of where the heads are. Once you find the sprinkler heads, you’ll likely be able to connect the dots between them, revealing the system below.

Completion time ranges from days to weeks, contingent on project size, environmental conditions, and regulatory approvals.

Trenching is a specific kind of digging. Trenching means digging a depression in the earth that’s deeper than it is wide, often with heavy machinery. Digging refers to any kind of removal of earth in order to create a human-made depression, hole, or cut in the earth’s surface. You can dig with big tools or even with just a hand shovel.
