LawnStarter’s published guide puts stump grinding at $131 to $438 nationally, averaging $272 a job. Thumbtack puts the national average at $307 to $426 for one stump. Both are national numbers, nobody publishes a Tampa figure, and your quote can land outside both because width, wood, access, cleanup, and one Florida notice rule all move it.
That last one is the part no cost calculator will tell you about, so it gets its own section below.
This guide picks up after the tree is already on the ground. If it isn’t yet, our tree removal cost guide covers that half of the job, and the stump grinding versus removal guide settles which of the two you actually need. Everything here is price and rules.
What does stump grinding cost?
Nationally, LawnStarter’s guide puts one stump between $131 and $438, with a $272 average per job.
The same guide reports per-inch pricing of $2 to $5 per diameter inch. Plenty of contractors also hold a $100 minimum, which is worth knowing if you’ve got one skinny stump and you’re wondering why the quote feels high for the size of it. You’re paying for the trip as much as the stump.
None of those are Tampa Tree Pro prices, and none of them are Tampa prices at all. We looked, and no published cost source breaks out a Tampa-specific stump grinding average. Treat the national figures as a sanity check, then get a written local quote.
What makes a quote comparable is the detail underneath the total: the stump’s widest diameter near ground level, the grinding depth you asked for, the access, the wood, and who hauls the chips. Our stump grinding service page explains how we connect Tampa Bay homeowners with insured crews.
Why do the two big cost guides disagree?
Because the two published figures aren’t built from the same set of jobs.
LawnStarter reports a $272 national average. Thumbtack reports $307 to $426 for one stump, with a wider national spread of $220 to $544. That’s a real gap, and it isn’t a typo in either place. Neither source says it’s measuring the same set of jobs as the other, and the bands underneath them don’t line up either.
Here’s the useful part of that disagreement. If two national sources can’t agree on the average for the same service, a calculator that’s never seen your yard isn’t going to do better. A grinder that rolls straight up an open driveway isn’t the same job as one that has to squeeze through a side gate, and no national average knows which one you’ve got.
How much does stump size change the price?
Size is the clearest way to compare published prices, though the two sources slice it differently.
LawnStarter splits its national figures three ways:
- Small stumps up to 10 inches: $40 to $75
- Medium stumps, 10 to 30 inches: $75 to $150
- Large stumps, over 30 inches: $200 to $417
Thumbtack uses narrower national diameter bands:
- Under 12 inches: $267 to $354
- 12 to 24 inches: $324 to $443
- 24 to 36 inches: $355 to $486
- 36 to 48 inches: $372 to $494
Those don’t line up, even at similar diameters, which is another sign the two sets aren’t describing the same scope of work. Measure your stump at its widest point before you call anyone, then ask each crew to measure the same way and put the method in writing alongside the number.
Does Florida law require anything before a stump grinder starts?
Yes, and it’s the step that separates a quote date from a start date.
Florida Statutes Chapter 556 is the Underground Facility Damage Prevention and Safety Act. Its definition of excavation is broad on purpose: any manmade cut, cavity, trench, or depression in the earth’s surface formed by removal of earth, or intended to penetrate or disturb the surface of the earth. An excavator, under the same chapter, means any person performing excavation or demolition operations. That language reaches a lot further than trenching for a water main.
Section 556.105(1)(a) requires notice not less than 2 full business days before beginning any excavation that isn’t beneath the waters of the state. The locate service is free. As Sunshine 811 puts it, it’s a free service, but the cost of not using it is high.
Skipping that notice is a noncriminal infraction, and the statute sets a civil penalty of $500 plus court costs for each one.
The City of Tampa says the same thing in its own words, right on its tree page: always call before you dig, by calling 811 or visiting sunshine811.com. That’s the city’s own tree guidance, not a construction bulletin.
So when a crew offers to grind a yard this afternoon that nobody has ever ticketed, they’re quoting around a step that exists. Whether the statute covers one particular job comes down to depth, location, and who’s operating the machine, and none of that is something we can settle for your property from here. What we can tell you is that a free ticket makes the question go away. This is what the law says, not legal advice for your yard.
Permits are a separate matter entirely. Our Tampa tree permit guide covers the tree ordinance side, which has nothing to do with underground utility notice.
How narrow is the homeowner exemption?
Narrower than most people assume, and the number to remember is 10 inches.
Section 556.108(1) exempts excavation performed by the owner of a single-family residential property, on that owner’s own land, and only up to a depth of 10 inches, provided due care is used and there’s no encroachment on any operator’s right-of-way, easement, or permitted use.
Read who that names. It names the owner. It doesn’t name a tree service the owner hires. And 10 inches isn’t much once a grinder is chasing a stump below grade.
Don’t treat a rental receipt as an answer here. If you can’t tell whether your job sits inside those lines, the free ticket costs you two business days and nothing else.
What does it cost to grind more than one stump?
Less per stump, if you group them into one visit.
LawnStarter’s national guide lists about $123 for the first stump, then $37 to $70 for each additional stump on the same trip. It also reports national hourly pricing of $125 to $200 per hour.
That drop makes sense: the setup, the trailer, and the drive only happen once. It doesn’t make the additional stumps free, and access and size still apply to each one. Ask for a single written total plus the per-stump adder, so you can see what a fourth stump actually costs you.
If you’re looking at a whole back lot full of them, that’s a different service. Land clearing gets quoted as a site, not as a count of stumps, and the estimate should say plainly which one you’re buying.
What gets added to the quote after the grinding is done?
Cleanup, most often, because a lot of base prices cover grinding and nothing else.
LawnStarter reports a national charge of roughly $2 to $3 per diameter inch for chip and debris removal. On a wide oak that’s a line item you’d rather see before the crew arrives than after. Ask whether the chips stay in your yard or leave in the truck, and get the answer in the written scope.
The same goes for grinding depth and surface roots. Two quotes that look close on price can describe genuinely different results, and the cheaper one can leave you a mound of chips and a ring of surface roots you’ll be tripping over in October. Ask each crew to describe what your yard looks like when they pull away.
Does grinding an oak cost more than grinding a pine or a palm?
It can, and hardwood is the reason.
LawnStarter reports a national hardwood addition of $50 to $150 per stump, naming oak and similar hardwoods. Around here that matters, because live oaks and laurel oaks are common in older Tampa Bay yards. The source attributes the upcharge to the extra effort and the wear on the equipment.
If species is moving your price, it belongs on the estimate in writing. When the tree’s been gone long enough that nobody’s sure what it was, an arborist consultation sorts that out before the quotes start disagreeing for the wrong reason.
Is renting a grinder cheaper than hiring one?
Sometimes on paper, and less often once you’ve added everything up.
LawnStarter puts national stump grinder rental at $178 to $364 per day, averaging $260. Set that against the hired figures above and the gap looks smaller than the rental headline suggests, especially on a single stump where a crew’s $123 first-stump national figure is already in range.
The rental price buys you the machine for the day. It doesn’t buy delivery, fuel, your Saturday, or hauling the chips, and those are the numbers people forget when they compare. It also doesn’t move the utility question, it just hands it to you: the exemption names the owner and stops at 10 inches deep, with the due-care and property-rights conditions attached. The free 811 ticket is the same free ticket either way.
What should a Tampa Bay stump grinding quote actually say?
Enough that you can hold two of them side by side and see the difference.
Look for these in the written scope:
- The measured diameter and the wood type
- The grinding depth you asked for
- How many stumps are included
- Access through gates, side yards, or the driveway
- Whether visible surface roots are in scope
- Whether chips stay or leave
- Any separate hardwood or cleanup charge
- How underground utility marking is being handled
- The total, and exactly what it covers
Access is the one people underestimate. A South Tampa side yard between a bungalow and a fence line is a different job than an open lawn in a newer subdivision, and a crew that’s seen it will quote it differently than one working from a photo.
If the tree itself is still standing, ask for tree removal as its own line rather than one blended number. Itemized quotes are easier to compare, and easier to argue with.
Frequently asked questions
What is the average stump grinding cost?
LawnStarter publishes a $272 national average inside a $131 to $438 range. Thumbtack reports a $307 to $426 national average for one stump. Neither is a Tampa figure, so use them as a sanity check and get a written local quote.
How is stump grinding priced by diameter?
LawnStarter reports a national rate of $2 to $5 per diameter inch, and many contractors hold a $100 minimum for the job. Ask how the crew measures diameter, then get that method and the resulting number in writing.
Is there a Tampa-specific stump grinding average?
No. No published cost source breaks out a Tampa stump grinding average, which is why the figures in this guide are labelled national throughout. A written quote against your actual stump beats either national average.
Does a stump grinding crew need to contact 811?
It depends on the depth, the location, and who’s running the machine. Florida law defines excavation broadly and requires advance notice for covered work, and the free 811 ticket settles the question without anyone guessing about your yard.
Can stump grinding start on the day of the quote?
Covered excavation needs notice not less than 2 full business days beforehand, so the quote date and the start date often aren’t the same day. Ask any crew how utility marking fits into the schedule they’re promising you.
Does an oak stump cost more to grind?
It can. LawnStarter reports an added $50 to $150 per stump nationally for oak and similar hardwoods, and oaks are common in older Tampa Bay yards. That’s a national figure, so get the local number in writing.
How much does cleanup add?
LawnStarter reports a national debris-removal charge of about $2 to $3 per diameter inch. Cleanup isn’t always in the base price. Ask whether the chips stay onsite, and get any removal charge written into the quote.
Tampa Tree Pro is available 24/7 across the Tampa Bay service area, and the crews we send are insured. Tell us about your stump and we’ll match you with someone who’ll quote the diameter, the depth, the cleanup, and the schedule in writing.
