Once a tree comes down, the stump is what's left staring at you from the lawn. It's a mower obstacle, a tripping hazard, and an open invitation to termites and carpenter ants. The good news is that grinding a stump is one of the most affordable jobs in tree care. This guide lays out typical St. Louis-area stump grinding prices for 2026, explains what pushes a quote up or down, and helps you decide between grinding, full removal, and doing it yourself.
How Much Does Stump Grinding Cost in St. Louis?
Stump diameter is the number that matters most. Measure across the widest point of the stump at ground level, including the flared roots at the base, because that's how most crews size the job. Here are typical St. Louis-area ranges:
Small Stumps (Under 12 Inches)
Cost: $100-$150
Ornamental trees, young maples, redbuds, crabapples, and most shrubs-turned-trees fall here. A small stump grinds out in 15-30 minutes, so you're mostly paying the minimum trip charge.
Medium Stumps (12-24 Inches)
Cost: $150-$300
This is the sweet spot for mature residential shade trees: silver maples, pin oaks, ashes, and sweetgums that were 30-60 feet tall. Expect 30-60 minutes of grinding plus cleanup.
Large Stumps (Over 24 Inches)
Cost: $300-$400+
Big oaks, sycamores, and cottonwoods leave stumps that can measure three to four feet across with a wide root flare. These need a larger, self-propelled grinder and an hour or more of machine time. Stumps beyond 36 inches are priced individually.
Per-Inch Pricing and Minimums
Many St. Louis companies quote stump grinding at $2-$5 per inch of diameter. A 20-inch stump at $3 per inch is $60 of grinding time, but you won't pay $60, because every company carries a minimum charge, usually $75-$150, to cover hauling the grinder to your address. That minimum is why a single small stump costs about the same as a medium one.
Multi-Stump Discounts
The trip charge is paid once, so the second, third, and fourth stumps are much cheaper than the first. If you have several stumps in your yard, or a neighbor in O'Fallon or Kirkwood wants a stump ground the same day, ask for a combined quote. Grinding five stumps together can bring the average cost down to well under $100 each.
What Changes the Price of Stump Grinding?
Two stumps of the same diameter can carry different prices. These are the factors a crew weighs when they look at your yard:
- Root flare and surface roots — A stump with wide, exposed buttress roots takes longer to grind than a clean cylinder. Some homeowners want surface roots chased out 3-6 feet from the trunk, which adds machine time.
- Species and hardness — Oak, hickory, and osage orange are dense and slow to grind. Silver maple, cottonwood, and pine chew up quickly. Old, partially rotted stumps are often the fastest of all.
- Grinding depth — Standard grinding goes 6-8 inches below grade, enough to lay sod. If you're pouring a patio or planting in the same spot, you may want 12-18 inches, which costs more.
- Access — Grinders range from 34-inch walk-behind units that fit through a standard gate to large tracked machines. A backyard stump with a narrow gate, steep slope, or tight side yard means a smaller, slower machine and a higher price.
- Rocks, concrete, and buried debris — Hitting a rock or an old fence footing dulls grinder teeth instantly. Stumps in rocky ground or near old foundations are quoted higher to cover tooth wear and slower progress.
- Utilities — Any stump near a gas meter, buried electric line, sprinkler system, or invisible dog fence requires a utility locate before grinding. Call 811 (Missouri One Call) at least three working days ahead; the service is free. Private lines aren't marked by 811, so tell your crew about anything you know is buried.
- Cleanup and hauling — Grinding produces a surprisingly large mound of chips: a 24-inch stump can generate several wheelbarrow loads. Most quotes leave the grindings raked into the hole. Hauling them away and backfilling with topsoil is typically an extra $50-$150.
Is Stump Grinding Cheaper Than Stump Removal?
Significantly. Stump grinding chips the visible stump down to 6-12 inches below the surface and leaves the root system in the ground to decay naturally over five to ten years. Full stump removal digs out the entire root ball with an excavator, leaves a large hole, and can cost two to three times as much as grinding, often $400-$1,000+ for a mature tree.
For most St. Louis yards, grinding is the right call. Removal makes sense only when you need the ground completely clear, such as for a new foundation, driveway, retaining wall, or a replacement tree in the exact same spot. We break the decision down in detail in stump grinding vs. stump removal.
Is It Cheaper to Grind the Stump With Tree Removal?
Yes, and this is the single biggest way to save. When a crew is already on site with equipment for a tree removal, adding stump grinding costs a fraction of scheduling it as a separate trip. The minimum charge disappears because the mobilization is already covered.
Ask for stump grinding as a line item on your removal estimate so you can compare. Some companies quote a low removal price and leave the stump out entirely, and you find out later. Our tree removal cost guide shows how the two services stack together on a typical St. Louis job. If you're on a tight budget, it's fine to remove the tree now and grind the stump later; the stump isn't going anywhere, and the price won't change much.
One caution: if you're removing a large tree that's over 24 inches in diameter, get the stump ground during the same visit. Very large stumps need a big machine, and bringing it back later on its own is the most expensive way to do it.
Should I Rent a Stump Grinder or Hire a Pro?
Rental stump grinders are available at St. Louis-area equipment yards and big-box stores for roughly $100-$200 per half day, plus a deposit, fuel, and a trailer or truck to move a machine that weighs several hundred pounds. On paper that beats a $150 grinding quote. In practice, it rarely does:
- Rental machines are small. A 13-25 hp rental unit takes two to four hours on a stump a commercial 60+ hp grinder handles in 20 minutes. A stump over 18 inches is a full afternoon of hard, loud work.
- The safety risk is real. A grinder throws wood chips and rocks at high speed. Professionals work in face shields, chaps, and hearing protection, and they know how to position the machine on a slope.
- Utility strikes are on you. Hit a gas line with a rental and you're responsible. A licensed and insured company carries that liability.
- Dull teeth are expensive. Hit one rock and you may owe the rental yard for a set of teeth.
Renting can make sense for one small, soft-wood stump in an open yard. For anything over 12 inches, or more than one stump, hiring a crew usually costs the same or less once you count your time and the rental extras.
What Happens After the Stump Is Ground?
Grinding leaves a shallow crater filled with a mix of wood chips and soil. Here's what to expect and how to finish the job:
- Use or remove the grindings. Fresh chips make decent mulch for beds and paths, but leave them out of vegetable gardens. If you plan to seed grass, rake most of the chips out first.
- Backfill and settle. Fill the hole with clean topsoil, mounded an inch or two high, because the mix will settle as the chips decompose. Water it in and top it off again in a few weeks.
- Seed or sod. Grass will grow over a backfilled stump area the same season. Expect a slight dip for a year or two as the underground roots break down.
- Replant carefully. Decomposing chips tie up nitrogen in the soil. Plant a new tree a few feet away from the old stump, or wait a season and add compost before planting in the same spot.
- Watch for mushrooms. Fungi feeding on the old roots sometimes pop up in the lawn for a few years. They're harmless to the lawn and a sign the roots are decaying as they should.
How to Get an Accurate Stump Grinding Quote
Stump grinding is easy to quote from a few details. When you call, have these ready: the stump diameter at ground level, roughly how many stumps you have, whether the stump is in the front or back yard and what the gate width is, and anything you know is buried nearby. Photos help, but any company should confirm the price on site before starting.

Frequently Asked Questions
Most residential stumps in the St. Louis area cost $100-$400 to grind. Small stumps under 12 inches usually fall at the low end, 12-24 inch stumps run $150-$300, and stumps over 24 inches can reach $400 or more. Many companies price by diameter at roughly $2-$5 per inch with a $75-$150 minimum.
Yes. Grinding chips the stump 6-12 inches below grade and leaves the roots to decay, so it takes less time and equipment. Full stump removal digs out the root ball and can cost two to three times as much. Removal only makes sense when you need the ground fully clear for construction, a foundation, or a new tree in the same spot.
Yes. Stump grinders cut below ground level, so buried gas, electric, water, and cable lines near the stump must be located first. Missouri One Call (811) is free and marks public utility lines. Your tree service should ask about private lines such as sprinkler systems, invisible fences, and landscape lighting before grinding.
You can, but not immediately in the same hole. Fresh wood chips pull nitrogen from the soil as they decompose and the old roots are still in the ground. Remove most of the grindings, backfill with topsoil, and either plant a few feet away from the old stump or wait a season before planting in the exact spot.
