Root Removal in Old Hickory, Tennessee
Roots don't stop growing when the tree comes down. We grind out root flare and cut back surface roots that are lifting walks, drives, and foundation lines.
The Root Problem Stump Grinding Doesn't Solve on Its Own
Grinding a stump takes the trunk and the flare directly under it down below grade. It does not touch the lateral roots running out sideways under your yard, and on a mature white oak those can run 20 to 30 feet from where the trunk stood. On the older bungalow lots around Hadley Avenue and Rayon Drive, those roots have had eighty or ninety years to work their way under sidewalks, driveway edges, and foundation footings, and they keep pushing even after the tree's gone.
We grind root flare out to the point where it stops interfering with mowing or foot traffic, then cut and grind visible surface roots beyond that if they're heaving pavement or a walking path. We don't chase every root underground — that's neither possible nor useful — but we take out what's actually causing the problem you called about.
American Elm and Sycamore Roots Behave Differently
American elm throws a dense, fibrous root mat close to the surface, which is why elm-lined lots near the old Village core often have grass that's thin and root-bound right up next to the trunk line. Sycamore, especially on lots closer to the Cumberland River, sends out wide surface roots that can look almost like a low wall by the time the tree is fifty years old. Sugar maple splits the difference — shallow but less aggressive than elm.
We adjust the grinding pattern to the species. Elm roots need more passes at a shallower angle to break up the mat; sycamore roots often need a single deep grind because they're thicker but fewer in number, and getting that wrong in either direction means either leaving root mass behind or spending extra time on a root that didn't need it.
When Roots Are Lifting a Sidewalk or Driveway Edge
This is the most common root call we get on original Village lots, where the sidewalks were poured decades before anyone accounted for a mature oak's root spread. We grind the root down below the slab line, usually 4 to 6 inches under the concrete edge, so the fix holds instead of the root pushing back up within a season. If the slab itself is already cracked, that's a concrete contractor's job — we handle the root, not the pour.
Driveway edges see the same problem, especially on lots where the driveway was widened or repoured at some point without anyone rerouting the root that was already growing toward it. We'll grind a channel along the affected edge rather than a single spot if the root's been running parallel to the concrete for any distance, since a partial fix just means the same crack reopens a few feet down the line next season.
Root situations we take on
- Surface roots heaving sidewalks or driveway edges
- Root flare left behind after a stump grind years ago
- Roots crowding a foundation line on older Village homes
- Elm root mats thinning out lawn near the trunk line
- Wide sycamore roots on river-lot properties
- Root cutting ahead of a fence line or paver install
Tree Root Removal in Old Hickory: the questions we get
Can you remove roots without grinding out the whole stump?
Yes, if the stump is already gone and it's just lateral roots causing trouble. We cut and grind the problem section without re-opening the full stump area, which is usually the case on lots where a stump was ground years ago and roots have kept surfacing.
Will cutting a root hurt a tree that's still standing?
It can, depending on which root and how close to the trunk. We won't cut a major structural root on a live tree without talking through it first — sometimes the better call is rerouting the sidewalk or living with a small heave rather than compromising a tree that's still healthy.
How deep do you grind roots under a sidewalk?
Typically 4 to 6 inches below the slab so a concrete patch or replacement pour has clearance and won't get pushed back up by regrowth or leftover root mass. We go deeper if the root is unusually thick or if a contractor tells us the new pour needs more clearance than that standard depth gives them.
Do old Village lots have worse root problems than newer neighborhoods?
Generally yes, because the trees are a century old in many cases and the hardscaping — sidewalks, driveways, foundation footings — was often built without much setback from the trunk. A newer subdivision with 20-year-old trees simply hasn't had time to develop the same root spread.
