Hiring a Stump Grinding Service: Per-Inch Pricing and the Quote

The diameter they measured for each stump and where they measured it; the per-inch rate and the minimum; the grinding depth (6–8 inches standard, more if you asked); whether surface roots are chased and how far; what happens to the chips (left, raked into the hole, hauled) and whether topsoil backfill is included; access notes and any surcharge; the price for each additional stump; and that 811 has been or will be called. A one-line 'grind stump $200' is a start, not a quote.

Tree services, which grind as a line item on removal and as a standalone service; landscape companies with a grinder; and stump-only operators — often one person with a tracked machine on a trailer — who are usually the cheapest for standalone work because the grinder is all they run. For one or two stumps, the stump-only operator; for a removal, the tree crew; for a lot, get both to quote.

Almost never; grinding is a separate line, typically $75–$150 as an add-on to a removal because the crew and machine are already there. It's the cheapest stump grinding there is. If a removal quote says 'stump included,' confirm it means grinding below grade, not cutting flush with the ground.

Call 811 for a locate before grinding below grade, and hand-dig or skip the area near marked lines. Ask who's calling — most companies do it as routine, but a one-person operator may expect you to. Then ask for the certificate of insurance: liability that covers a utility strike and property damage from thrown debris, and workers' comp for the operator. A company without it is a company whose accident becomes your claim.

6–8 inches for lawn. 12–18 inches if you're planting a tree in the same spot, setting a post, or building a patio, deck or slab over it — and say so in the quote request, because it changes the machine and the price. For a foundation or a driveway, ask about full removal instead; roots decaying under a slab leave voids.

For a lawn you care about, yes, or do it yourself — grindings left in the hole decompose into a soft dip for a year or two and tie up nitrogen so grass struggles. Hauling and topsoil backfill is $50–$150. The chips are fine mulch for beds and paths if you have somewhere to put a wheelbarrow or two.

No insurance certificate; 'we don't need to call 811'; a price with no depth or no measurement; cash-only with no invoice; a machine that can't fit through your gate and a plan to grind the stump from the driveway anyway; and a quote far below the others, which usually means a flush cut or a shallow grind. Also anyone who quotes over the phone from your description without asking for the diameter at grade.

It's the structure of the pricing, not a discount: the first stump carries the trip charge and each additional one is $30–$60 or a per-inch rate without the minimum. Five stumps run about twice the price of one. If the neighbors have stumps, one visit for both properties is cheaper for everyone; ask the company to quote it as one job.
