Customers say: Quick response

"Mr. Dolloff was prompt in his response to our inquiry into landscaping projects we were considering. He gave us a free estimate on several projects. The cost seemed very fair and we had him complete a quarter of the entire project ~ grooming a hillside with severe erosion and creating a parking area for 2 cars. The hillside is beautiful. Exactly what we wanted and better than we expected. The parking area was not what I would call satisfactory. But in all honesty, they completed both jobs on time but unfortunately it was just the day before we got all that heavy rain the weekend of October 21st. We are planning for him to complete the other landscaping we need down and he offered to clean up the parking area as soon as the weather settles down."

"We loved working with Sean - we were redoing our driveway and in that process we found out that we needed had to have a French drain installed through half our property. This was extremely anxiety provoking but Sean was extremely communicative - he even connected with our paving company to make sure all the work that he did would support their project as well. He showed up on time and made sure the job was done well. He followed up with us numerous times to make sure we didnâ t have any issues. Highly recommend and would hire him again for other (hopefully planned) projects on our property."

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.

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.

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

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.

Yes, trenchers can go through gravel. Gravel is made up of smaller, softer rocks that certain trenchers are able to cut through. Just be sure to use a rock wheel trencher or chain trencher, both of which are made to cut through rocky landscapes and gravel pathways without dulling the teeth or chain.
