"I had about 5 acres to get cleared out from over growth, I called Freedom Forest Management and a gentleman named Levi was out at my property two day later to give me a quote, the quote they gave me was a little pricey compared to others but they were able to get to it in a couple of days compared to others that were 3-4 weeks out. They did a bang up job cleaned the area up really good even trimmed up a tree I had since he said needed it to help with growth. I definitely got the quality of work I paid for and then some."

Excavating questions, answered by experts

Skunk digging looks like a series of small, cone-shaped holes on a lawn or around the perimeter of a home, porch, deck, or shed. The holes that skunks dig when searching for grubs tend to be no more than four inches in diameter and may be up to four inches deep.

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.

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.

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

As a general rule, the protected area should be about 1½ times as wide as the canopy of the tree’s leaves. This digging measurement can vary by tree species and the age of the tree. Of course, that can be a lot of fencing for larger trees, which is why our first step is about making difficult decisions on which trees to save.
