"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."

Excavating questions, answered by experts

A perc test can take anywhere from one to eight hours to complete. The total time depends on factors like the amount of excavation required, the depth and width of the holes, and whether multiple test holes are needed. For a single hole, the process of filling it with water and monitoring the drainage rate usually takes less than an hour. Professionals can often complete the entire test in a single day. While it's possible to get results the same day, some companies may take a few days to provide the official report.

Call 811 to locate and mark the gas lines at least three days before digging. In many areas, you can dig within 18 inches of the lines, though in some locations, the distance may be further. Check local regulations, as you may need a utility company representative onsite when digging. Document your calls to 811 and precautions taken to avoid gas lines. A homeowner can be held liable for hitting a gas line in some cases, but contacting the proper authorities and following all guidelines can offer protection.

Hard soil could be a sign of overly dry dirt, either from poor drainage or drought. It's important to test the nutrient levels, density, and drainage capacity of your soil to see if it's absorbing water properly. Begin by adding a light layer of water and observing how long the soil retains moisture. If you experience a good deal of runoff, you may need to aerate your lawn, apply a wetting agent, or hire a professional for a closer look.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.

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.
