Stump Grinding Cost: Average Prices & Cost Factors

A stump left in the yard is an eyesore, a tripping hazard, and a home for pests. Grinding is the most common fix. A machine with a spinning cutting wheel chews the stump into wood chips below ground level, leaving the roots to rot in place.

Price is driven by stump diameter, the species of the tree, and how easy the machine can get to it. Most companies charge a flat rate per stump, or a per-inch rate with a minimum service charge.

Diameter, measured across the top at about knee height, is the biggest pricing factor because it determines how much wood the grinder has to remove.

If you have several stumps, mention that when you call. Many crews give a discount for each additional stump once the grinder is already on site, and some will price by the hour for larger jobs.

Hardwoods such as oak are denser than softwoods, so they take longer to grind and wear out the cutting teeth faster. That is why some companies add a surcharge. Obstacles near the stump, such as fences, rocks, and underground lines, can add time as well.

These two terms are not interchangeable.

• Grinding: Cuts the stump down below the surface. It is faster, cheaper, and disturbs less of the yard. Roots stay underground and decay over time.
• Full removal: Digs the stump and major roots out. It takes heavy equipment and leaves a large hole to fill. Choose it when you plan to build over the spot or when roots are damaging a structure, pipe, or driveway.

If you want to replant a tree in the same place, ask the contractor how deep they will grind and whether they remove the chips. Fresh chips can steal nitrogen from new plants.

Renting looks like a bargain, especially with several stumps. But a stump grinder is a heavy machine with exposed rotating blades that throw debris. It can injure an inexperienced operator, and a buried utility line is easy to strike. Before anyone digs or grinds, call 811 to have underground lines marked.

For one or two stumps, a professional is usually the safer and less stressful option, and the rental cost and your time can narrow the gap. If you do rent, wear eye, ear, and leg protection and read the operating instructions.

Grinding leaves a mound of wood chips and a patch of disturbed soil. You have a few choices for what comes next. Many people rake the chips into a pile and use them as mulch in garden beds, though fresh chips are best kept away from young plants. Others have the crew haul them off, which is worth asking about when you get the quote. To restore a lawn, remove most of the chips, fill the hollow with topsoil, and seed or lay sod. If you plan to plant another tree or shrub, wait until the grinding debris has settled and the soil has been refilled and tamped.

Leftover roots can send up sprouts, especially on species that resprout readily. Cut those back as they appear. A healthy tree that was cut down recently is more likely to sprout than one that died years ago.

The sources below do not agree because they define stumps differently. One may average across all sizes and another may assume a typical residential stump. Some include cleanup and chip removal, while others do not, and local labor rates vary by city.

• Is the price per stump, per inch, or hourly?
• Does it include chip removal, or do the chips stay on site?
• How deep will the stump be ground?
• Will the crew fill the hole and level the area?
• Is there a minimum charge for a single stump?

Small local tree services often price competitively on stump work, and bundling it with tree removal can reduce the total.
