"Ike was great from start to finish. He came quickly to give an estimate and started promptly. He did a great job at everything the job required. He finished on time and cleaned up well. The job was complex and he triple checked each item to ensure it was exactly what we wanted. Several things were more difficult than expected but he still got it done on time. He excavated, created and graded a 100+ft ledge perfectly. I would recommend Isaac Nathaniel to anyone."

"Campbell services provided me timely excavation of driveway. His crew were professional and courteous. I was pleased with the time they took in making sure the mess was cleaned to my satisfaction along with taking extra care to preserve the existing landscape. I only wish other companies would adopt that type of work ethic."

"Hector came up with a great solution for some drainage issues at our house. They were quick and efficiently and very cost effective. After they left it looked like they had never been there. Highly recommend."

"Responsive, friendly, punctual, and highly competent. It helped that I was overseeing the work because some decisions and improvisation had to be done on the fly with the repair of a sprinkler valve, installation of and two ball-valve cutoffs, and relocation of an adjacent faucet."

"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."

Excavating questions, answered by experts

You can bury underground electrical wire six inches deep—but only if you use a rigid metal electrical conduit. For rigid, non-metallic conduits, bury the wire at least 12 inches deep. If using an underground feeder cable rated for direct burial, you'll need to place it at least 18 inches deep, as it has no conduit for extra protection.

Sewer lines can be buried anywhere from 18 inches to 8 feet deep, with a common average depth between 18 and 30 inches. The exact depth depends on local factors like climate and soil type. In colder regions, pipes must be buried deeper (below the frost line) to prevent freezing, sometimes as deep as 8 feet. The digging depth can also impact the cost of sewer line replacement. To find the specific depth for your property, you can check the building plans for your system, which should be on file with your city or local sanitation department since permits are required for installation.

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.

A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.
