Stump Grinding in Sunset Oaks, Hermitage
Yes, Sunset Oaks off Chandler Road is on our regular run, seven minutes out. Weekday photo quotes usually come back inside two hours. If the walk is already lifted and someone is due to pour, tell us the concrete date and we will get ahead of it.
The tree lifted the sidewalk and now the whole thing is a sequence
Sunset Oaks went in from 1994 through the early 2000s, all brick, quarter-acre lots, matched trees down each street in the strip between the walk and the curb. The design worked beautifully for fifteen years. What happens after twenty-five is that the surface roots thicken, the concrete above them cracks and tilts, and one panel of your sidewalk now sits an inch and a half proud of the next one.
That is when this stops being a tree problem and becomes a scheduling problem. You cannot pour new concrete over live roots, because they will do it again. You cannot grind a stump properly after the new walk is down, because the machine has to work exactly where the fresh slab is. And nobody wants to pay a concrete crew for a mobilization twice.
So the order matters: tree out, stump and the offending root runs ground out wide and low, then the concrete. Homeowners who do it in that order pay once. The ones who pour first are calling us in eighteen months about a fresh crack.
Grinding for a concrete crew instead of for a lawn
A routine residential grind takes the stump six to twelve inches under the surface, which is plenty for grass. Preparing ground for a sidewalk pour is not that job. The roots that lifted the panel run laterally under the slab, sometimes four or five feet in from the trunk, and they have to come out too or the new work fails the same way.
What we do instead is take the stump low, then follow the two or three structural laterals heading toward the walk and grind them below the base course depth your concrete contractor is planning. That means asking your contractor what they are pouring on: four inches of slab over four inches of compacted stone means we need to be clear of about ten inches, not six.
We also pull the shavings out of the trench rather than pushing them back in. Wood chips are terrible base material, they compress and rot, and a contractor who finds them under his stone will not be happy. Clean void, backfilled with soil or stone as they prefer.
Four species, four completely different grinds
The planting palette here is standard mid-nineties and each element behaves differently. The Bradford pears are the sidewalk offenders, small-trunked and shallow-rooted with runs that go straight for the nearest crack. Fast to grind, cheap, but the root chasing is the real work.
Sugar maple is the nicest tree on these streets and the one people are most reluctant to lose. It is moderately dense, grinds steadily, and has a base that flares broadly at the ground so the visible stump understates the job by a good margin. Pin oak brings its own signature problem, which is a dense mat of fine surface roots across the whole drip line rather than a few big ones, so the ground around it comes out looking chewed and needs raking and seeding after.
River birch is the outlier. Multi-stemmed, so what looks like one stump is three or four trunks fused underground, and the wood is stringy and wet. Leyland cypress along the rear property lines is quick, resinous work that gums the wheel and needs a stop to clean out.
Chandler Road, Dodson Elementary and the school-run window
Dodson Elementary is a National Blue Ribbon school and the traffic reflects how many families want to be in its zone. Between about 7:15 and 8:00 in the morning, Chandler Road and the streets feeding it are not a place to be setting cones out around a sidewalk.
We work Sunset Oaks mid-morning through early afternoon for that reason, and if the stump is in the curb strip we set the trailer nose-in on your driveway rather than parking along the street where a bus has to squeeze past.
If you are on a corner lot where the walk wraps, mention it. The wrap means twice the sidewalk length adjacent to the tree and usually a second root run heading the other direction, and that changes both the time on site and the price.
If your sidewalk is already lifted, have this ready
- A photo of the tilted panel taken from ground level, so the lift is visible
- Roughly how far the trunk sits from the edge of the concrete
- Whether the driveway apron is affected as well as the public walk
- The name and date of the concrete contractor, if one is lined up
- What they intend to pour on, so we know how deep to clear the roots
- Whether the sprinkler line crosses the strip, and where the heads sit
What we do in Sunset Oaks
Sidewalk and stump questions from Withers Place
Who is responsible for fixing the sidewalk, me or Metro?
In Davidson County the answer depends on the street and the situation, and it is worth a call to Metro Public Works rather than an assumption from us. What we can tell you is the technical part: whoever pours it, the roots have to be out below the base course first, and getting a stump ground properly is the cheap step in that whole sequence.
If I grind the stump, will the concrete stop moving?
Only if the laterals under the slab come out with it. A dead root does not shrink back overnight but it stops growing, and stops pushing, so the movement ends. The existing lift will not settle back down on its own, though, so if the panel is already tripping people it still needs replacing. Grinding prevents the next one, it does not undo the last one.
Do I need to be home while you work?
Not for a front-yard or curb-strip stump, as long as we can get to it and you have told us where any private lines run. Plenty of Sunset Oaks jobs happen while people are at work. For anything behind a locked gate we need access arranged, and for a job where the finish level matters to you, being there for five minutes at the end is worth it.
My sugar maple is fine but the pear next to it has to go. Can you get one without hurting the other?
Yes, and we would rather. The maple's feeder roots occupy the same top few inches of soil, so the technique is to grind the pear stump itself thoroughly and only chase laterals in the direction away from the maple. You will lose some fine root on that side and the tree will not notice. We keep the machine off the maple's root zone entirely on the drive in.
