Why the range is so wide
$75 to $1,000 looks like a range that tells you nothing. It's actually telling you that stump grinding is priced almost entirely on three things, and they vary more than tree height does.
Diameter
Measured at ground level, including the flare. Many providers price per inch. A 10-inch ornamental stump and a 40-inch oak stump are different jobs by an order of magnitude.
Roots
Surface roots radiating from the stump each need grinding too if you want the area level. Species with big buttress roots add real time.
Access
A tracked grinder needs a gate wide enough to get through. A back-yard stump behind a 30-inch side gate may mean a smaller, slower machine — or removing a fence panel.
Also on the list: whether the stump is fresh or old and rotten (old is easier), whether there's rock, concrete, or old hardscape in the root zone (grinder teeth are expensive), and how many stumps there are — a second stump on the same trip is usually much cheaper than the first.
What a stump grinding quote includes — and doesn't
- Included: grinding the stump to a stated depth below grade — ask what depth; 4–12 inches is typical — and usually the visible surface roots within a stated radius.
- Often extra: hauling away the chip-and-soil mound, backfilling with topsoil, seeding or sod, and grinding deeper for replanting.
- Not included: locating underground utilities. Call 811 before any grinding near a gas line, irrigation main, or sewer lateral — a reputable provider will ask you to, or do it themselves.
Grinding vs. full stump removal
Grinding leaves the root system in the ground to decay and levels the surface. Full removal digs the stump and major roots out with an excavator, leaves a large hole, and costs several times more. For lawn, a garden bed, a patio on a slab, or a new tree planted a few feet away, grinding is the right answer. Full removal is for a foundation, pool, or footing going in exactly where the stump is. If a provider quotes only full removal for a residential yard, ask why.
Doing it with the removal
If you're removing the tree, ask for the stump as a line item on the same quote. The crew is already there with equipment and the price is usually better than a second visit — and unlike the removal itself, a stump can wait, so if the removal is an emergency you can still schedule the grinding for a normal appointment. Full removal pricing is on the Modesto tree removal cost page.
Licensing note
Many single-stump jobs sit under California's $1,000 minor-work threshold, which means an unlicensed individual working alone can legally do them. That's a legal floor, not a recommendation: a stump grinder is a serious machine, and the risk of an uninsured worker hitting a gas line or a sprinkler main on your property is yours. Ask for insurance either way, and check any CSLB number at cslb.ca.gov.
