"Wonderful crew to work with. Very concerned about making sure they understand the end result you are looking for and checking at different stages to make sure they are meeting that expectation. Every member of the crew that came to our site was courteous and left the job site looking as clean as they could every day. Highly recommend."

"Hilltop Excavation project leader and owner Micheal Schwartz reworked my entire driveway and built a retaining wall to divert runoff water from undermining my houseâ s foundation. He did an exceptional job, not only is the runoff water running far from my house but I also gained three times the parking space in my driveway. He is a very friendly and knowledgeable man with an exceptional work ethic. I would highly recommend him for any excavation work that you may need done."

Excavating questions, answered by experts

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.

Yes. A metal detector is one of the quickest and easiest ways to find your septic tank. However, metal detectors can be too expensive (costing upward of $300 in some cases), and not everyone has a metal detector just lying around. If that’s the case for you, you can also take a long metal rod and poke it into the ground at regular intervals until you hit something—likely your septic tank lid.

Yes, an excavation company is the best option for land grading and yard leveling. General landscapers might be able to tackle these projects, but an excavation company will do a better job because they’re used to operating the necessary heavy machinery. Landscapers might opt to do the work manually, which takes much longer and could cost you more in labor fees. Finally, excavation companies will understand local regulations and know when you need permits to legalize the work, while a landscaper might not.

Yes, professional installations include trenching or borehole drilling required for ground loops.

Trenches are typically 12 to 24 inches deep and 8 inches wide. However, the required depth depends on the specific project and local ordinances. For example, a French drain may need to be 18 inches deep, while a water pipe might require a depth of 24 inches and a drainage pipe 36 inches. Your city or county may have specific regulations, so it's wise to consult with an excavation professional to determine the correct depth for your project.
