Stump grinding vs. full stump removal
Stump grinding uses a machine with a spinning toothed wheel to chew the stump down into chips, below the level of the lawn. The roots stay in the ground and slowly break down. It's quick, tidy and the most common choice.
Full stump removal means digging or pulling out the stump and its main roots. It's useful when you're building a foundation, patio or driveway right where the tree stood, but it costs more and leaves a big hole that needs filling.
How deep, and what's left behind
Most grinding goes several inches to about a foot below grade. Tell the provider what you plan to do with the spot — lawn seed needs less depth than planting a new tree. You'll be left with a mound of chips and soil. You can rake it into the hole and top with soil, spread it as mulch, or ask for it to be hauled away.

Call Before You Dig: CT 811
Gas, electric, water and cable lines often run closer to stumps than you'd guess, especially along front yards in older Fairfield neighborhoods. Connecticut's Call Before You Dig service (dial 811) arranges free utility mark-outs before digging. Ask your provider whether they request the mark-out or whether you should.
What affects stump grinding prices
- Diameter — measured across the widest point at ground level; bigger stumps take longer.
- Number of stumps — several stumps in one visit usually cost less each.
- Access — gates, steps, retaining walls and steep slopes can limit which machine fits.
- Roots and surface roots — grinding out large surface roots adds time.
- Cleanup — hauling away chips or adding topsoil and seed costs extra.
If you're having a tree taken down anyway, ask for grinding to be priced in the same quote. See our tree removal cost guide for broader pricing.
Stump grinding FAQ
How deep does stump grinding go?
Commonly about 4 to 12 inches below the soil surface, depending on the machine and what you plan to do with the spot. If you want to plant a tree or build in that spot, ask for deeper grinding or full removal.
What happens to the wood chips?
Grinding leaves a pile of chips and soil roughly the size of the stump. Some homeowners keep it to fill the hole or use as mulch; others pay to have it hauled away. Ask what the quote includes.
Do I need to call 811 before stump grinding?
Grinding disturbs the ground, so underground utilities should be marked first. In Connecticut you can request a free mark-out through Call Before You Dig (CT 811). Many providers handle the request — confirm who's doing it.
Will the roots grow back?
Most hardwood stumps won't resprout once ground below grade, though a few species may send up shoots from remaining roots for a season. Those can be mowed or pulled.
Is grinding cheaper than full stump removal?
Usually, yes. Pulling out the whole stump and root ball takes heavy equipment and leaves a large hole to fill, so it costs more and disturbs more of the yard.
