Grind it, pull it or leave it
A stump grinder is a heavy spinning wheel fitted with cutting teeth. The operator swings it side to side across the stump, a little lower with each pass, until the wood is shaved down below the surface. The main roots stay in the ground and rot over the following years. Because it disturbs only a small circle of lawn, grinding is the usual choice in a finished yard.
Pulling a stump means digging it out, root ball and all, with an excavator or a skid steer. It leaves a much bigger hole and more torn-up ground, but it gets the wood out. That's worth it where something solid is going on top, such as a concrete pad, a shed, a carport or a driveway extension, because buried wood keeps rotting and the ground over it keeps sinking.
Leaving the stump a few inches high is the cheapest choice. It also leaves an obstacle for the mower and a tripping hazard in the grass, and some trees will send up sprouts from it.
File the SC811 ticket first
A grinder works below the surface, right where buried service lines run. SC811, South Carolina's call-before-you-dig center, says on its homeowner page to submit your request at least three business days before digging begins, not counting the day you file, weekends or holidays. Its 2026 quick reference guide gives the window as three to twelve business days ahead, and lists phone 811 or 1 (888) 721-7877 for anyone who'd rather call than file online. The same guide names planting trees, shrubs and other landscaping among the homeowner jobs that need a locate request.
If a contractor is doing the grinding, ask whether they file the ticket themselves and wait for the marks before they start. Paint and flags in the yard are the sign that it was done.
Wells, septic lines and other private lines
If your home runs on a private well or a septic system, those and any other lines you own deserve their own walk-around before the grinder arrives:
- Water line from the well. It runs underground from the well to the house, and its path isn't always obvious from the surface.
- Septic tank and drainfield. A grinder, or roots torn out of the ground, can crack the pipes, and heavy machines shouldn't be driven across the drainfield.
- Power to a shop, barn or pump. Buried electric runs you or a previous owner installed won't be marked as a utility's line.
- Sprinkler pipes and lighting wire. Easy to chew through and easy to forget.
Mark them with flags or point them out in person. If you're unsure of a line's exact path, flag the part you know and tell the crew the rest is a guess.
Chips, red clay and a sinking hole
Grinding leaves a mound of wood chips mixed with whatever soil the wheel pulled up, which in many Lancaster County yards means red clay, and a bowl-shaped hole where the stump stood. Wood shrinks as it decays, so a hole backfilled with chips alone will slowly sink.
- Pull the bulk of the chips out of the hollow with a rake. They work as mulch for beds and around trees, kept a few feet back from the house.
- Fill the hole with topsoil, tamp it, and leave it slightly mounded above the lawn.
- Seed or sod the patch to match the yard.
- Top it up again after a few months, once the roots below begin to break down and the patch settles.
Ask whether the price includes raking out the chips, hauling the extra and bringing in fill, or whether the crew grinds and goes.
Pine stumps and leftover wood
When a pine comes down near other pines, what's left on the ground matters. Clemson's Home and Garden Information Center notes that Ips engraver beetles are drawn to stressed or injured trees and to logging slash, and it advises removing slash and downed trees near healthy pines because Ips can breed in them. It also warns that fresh wounds on neighboring trees can attract beetles, so the crew should keep the grinder and the equipment from scraping the trunks and roots of the pines you're keeping. See pine tree removal.
If the tree is still up
The stump comes after the tree. For an established home on a platted lot outside town limits, the county's current tree standards generally don't stand in the way of removal, but tree save areas, state road strips and homes inside a town are worth a call first. See tree removal and the rules guide. Grinding the stump at the same visit as the removal saves bringing the machine back.
What stump grinding costs
Thumbtack's tree removal cost guide, updated March 24, 2026, prices grinding on its own, after the tree is already down, by the stump's diameter:
| Width of the stump | Thumbtack, March 2026 |
|---|---|
| Less than 12 in. | $267 to $354 |
| 12 in. to 24 in. | $324 to $443 |
| 24 in. to 36 in. | $355 to $486 |
| 36 in. to 48 in. | $372 to $494 |
Elsewhere on the same page Thumbtack puts the average at around $307 to $426 depending on trunk diameter, which doesn't quite match its own table. Either way, these are national numbers. The number of stumps, how far the machine has to travel across the yard, big surface roots, and how much cleanup you want all move the local price, and the contractor's written price is the one that counts.
Grinding mistakes to avoid
- No locate ticket. The wheel cuts exactly where service lines are buried.
- Forgetting the private lines. Well lines and septic pipes aren't on the utilities' maps. SC811 points owners to a private locating service for lines like these.
- Standing too close. A grinder throws chips and small stones hard. Keep children, pets and cars well back, and shut nearby windows.
- A grind that stops short. Grass can cover a shallower grind than a replacement tree or a slab needs. Settle the depth beforehand, on paper.
- Leaving the chips in the hole. The spot sinks as they rot.
When grinding isn't the answer
If a slab, shed or driveway is going over the spot, ask about pulling the stump instead. If the tree is still standing, start with tree removal. And if you're clearing many stumps from wooded acreage for a building site or pasture, that's land clearing, a different job with its own equipment.
Stump questions
How deep will the stump be ground?
That depends on the machine and what you plan for the spot. Tell the contractor whether it's grass, a flower bed or a new tree, and get the depth in writing.
Will the roots keep sprouting?
Some kinds of trees push up shoots from the roots after the trunk is cut, and others don't. Ask what your kind of tree tends to do.
Is it cheaper to grind several stumps in one visit?
Usually. Bringing the machine out is part of the cost, so each added stump tends to cost less than the first. Get the total in writing.
Can I rent a grinder and do it myself?
Rental machines exist, and the SC811 ticket applies to homeowners too. The flying debris and the buried lines are the same hazards whoever runs the machine.
This site sends each request to one independent contractor working around Lancaster. It grinds no stumps itself.
