"I hired this pro to do a retaining wall and remove an old cement walkway and add back in a paved one! The project came out beautifully! Bobby was wonderful, very easy to talk too, very responsive to text and calls. I was never left waiting to hear back! His employee Ray was just as nice and helpful, I would recommend them over any big company! Such attention to detail!"

Excavating questions, answered by experts

The best way to protect tree roots is to avoid the roots entirely by excavating outside the root radius of the tree. For nearby projects, it’s a good idea to construct a temporary retaining wall. But that’s not always possible, depending on the project and the root system. In these cases, consider using alternative equipment like an auger to tunnel under the ground.

Remember, tree roots can damage nearby cement foundations as they grow. If a tree is close enough to interfere with large excavations, it may be better to remove the tree than risk future problems.

A trench that is less than 5 feet deep often doesn't require a protective system. Most residential trenches will not go this deep (the typical residential drainage trench is just 18 inches deep). In the event that an excavator needs to dig more than 5 feet beneath the surface, a protective system is required unless the excavation is in entirely stable rock.

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.

After you successfully remove your boulder, you have a few options for what to do to get rid of it. You can rent a dumpster if your yard has many boulders or if you’re planning a larger project. You can even save the boulder and reuse it elsewhere on your property to save on landscaping costs. A few ideas include using the boulder as a natural, abstract statue, breaking it into smaller pieces to line your garden bed, or offering it to a landscaping company that could reuse it for another project.

Yes, you can excavate in the winter, but it might make the job harder. Frozen ground is harder to dig, and snow or ice can make the work site more hazardous. A contractor may need special equipment and techniques, such as ground-thawing methods, to break through frozen soil. Although winter excavation is possible, it may take longer and be more costly than excavating during warmer months.
