"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

Prior to excavation, you should prepare the dig site and call 311 before you sign anything.

To get your site ready for excavation, you should move anything in the area that isn’t affixed to the land. You can save money on the excavation by removing hardscaping, including walkways, decks, concrete patios, and paver patios.

Before you carry out any digging, you should call 311 to confirm that there are no utility lines running through your excavation site. Skipping this step could lead to severe injury and property damage if your excavator hits a water, sewage, or gas line.

The digging depth will depend on the size of the trencher you use. Even smaller units can dig up to 4 feet deep, which is plenty for a DIY job. However, much larger trenchers can reach a depth of 18 feet and are better used by a team of pro contractors, not a single DIYer. As with all home improvement projects, use the right tool for the job and proceed with caution.

We recommend removing the stump, and grinding is a popular way to do it. You can also dig out small stumps or stumps that have fully decayed instead of grinding them. However, don’t try using acids or fire for killing a tree stump, which is a fire hazard and illegal in many areas.

Leaving the stump alone invites eventual problems, including attracting termites, mold, and fungi.

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.

Landscape edging is more DIYable than trenching. You can DIY your own digging projects, but proceed carefully and only with proper knowledge of the equipment and appropriate safety measures in place. Keep in mind the project's scope and estimate how long it will take you to do it on your own. While you can certainly save money by DIYing home improvement projects, you can’t exactly hide an unfinished—or worse, ruined— landscaping job from the neighbors. It’s always safer to call an excavation pro near you to get an estimate.
