The default 4–6 inches works for most residential jobs. Deeper grinding makes sense in specific situations — replanting, foundations, persistent sprouters. Here's the depth menu and what each tier costs.
| Tier | Depth | Cost premium | When to use |
|---|---|---|---|
| Standard grind | 4–6 inches below grade | Base rate ($150–$600) | Lawn restoration; spot disappears under grass within a season |
| Medium grind | 6–8 inches below grade | +$20–$50 | Aggressive sucker-shooter species (silver maple, willow) or repeated regrowth |
| Deep grind | 8–12 inches below grade | +$30–$80 | Replanting a tree in the same area within 12 months |
| Foundation-adjacent grind | 12–18 inches below grade | +$80–$150 | Stumps within 10 feet of foundation, septic, or sewer line |
| Custom deep | 18+ inches | Quoted by hour | Removing entire root flare for construction or large-tree replanting |
At 4–6 inches below grade, several things happen that make the spot effectively "gone" for residential purposes:
For homeowners who just want the eyesore gone and grass to grow back, standard depth is the right answer.
Standard grinding goes 4–6 inches below grade — enough that the spot disappears under grass within a season. That's the default for 90% of residential jobs in Lake Country. Deeper grinds make sense for specific situations: 8–12 inches if you're replanting a tree in the area within 12 months, 12–18 inches if the stump is within 10 feet of a foundation or septic field. Going deeper than 6 inches costs $30–$150 extra depending on the depth.
Yes for most residential lawns. At 4–6 inches below grade, the stump is invisible from above, the spot can be filled with topsoil and reseeded, and grass grows over it within a season. Deeper grinding is only needed for replanting trees, foundation safety, or aggressive sucker-shooting species like silver maple and cottonwood that send shoots from surface roots.
Most lateral tree roots stay in the top 18–24 inches of soil — that's where oxygen and water are available. Tap roots extend deeper (3–6 feet for mature oaks) but are smaller-diameter and don't need to be ground out for the stump to die. Once the trunk is cut, all roots die from lack of photosynthesis. Grinding 4–6 inches removes the part of the root flare that's visible/tripping-hazardous; the rest decomposes naturally over 5–10 years.
Not really. The roots die regardless of grind depth — they have no trunk to feed them after grinding. What deeper grinding does is remove more residual wood from the immediate area, which (a) prevents sucker shoots in aggressive species, (b) reduces the volume of decomposing wood in the future, and (c) makes the spot safer for replanting trees. The roots themselves decay naturally over 5–10 years either way.
8–12 inches below grade is the standard for replanting trees in the same area. This removes the root flare and the largest lateral roots, leaving enough clean planting depth for a new tree's root ball. Wait 6–12 months after grinding before replanting to let the soil chemistry stabilize — wood-decay fungi populations are elevated for ~12 months and can interfere with new tree establishment. Plant the new tree 6–10 feet away from the original stump location even after deep grinding.
Three reasons: (1) more time on-site (each additional 2 inches of depth roughly doubles grinding time), (2) more tooth wear (deeper soil has more rocks in Wisconsin glacial-till), (3) more chips to dispose of (deeper grinding produces 50–100% more chip volume). The premium is $30–$80 for medium/deep grinds, $80–$150 for foundation-adjacent. We'll quote it explicitly when we see the stump's context.
