Got a tree stump you need gone? The first question most homeowners ask is: how much will it cost? The honest answer is it depends on a few things, but most residential stump grinding jobs in the Wollongong and Illawarra region fall between $200 and $500. This guide breaks down exactly what affects the price, what’s included, and how to get an accurate quote for your property.
How Much Does Stump Grinding Cost?
Stump grinding prices vary based on the size of the stump, the timber species, how easy it is to access, and how many stumps you need done. Here’s a general guide for residential properties in the Illawarra, Shoalhaven, Southern Highlands, and Southern Sydney areas.
| Stump Size | Approximate Diameter | Typical Cost Range |
|---|---|---|
| Small | Under 300mm | $200 – $250 |
| Medium | 300mm – 500mm | $250 – $400 |
| Large | Over 500mm | $400 – $600+ |
| Tight access | Any size | Case by case basis |
| Multiple stumps (same visit) | Any size | Discounted per-stump rate |
These are approximate ranges for standard residential jobs. Every property is different, so the best way to get an exact price is with a free on-site quote. There are no call-out fees for quoting.
Factors That Affect Stump Grinding Cost
No two stumps are the same. Here are the main variables that determine what you’ll pay.
1. Stump Diameter
This is the biggest factor. A 200mm stump from a small ornamental tree takes a fraction of the time compared to an 800mm eucalyptus. Larger stumps mean more material to grind through, more wear on the machine, and more time on site.
2. Timber Species and Hardness
Hardwood species like ironbark, spotted gum, and turpentine are significantly denser than softwoods like pine or camphor laurel. A hardwood stump can take three to four times longer to grind than a softwood of the same diameter. This is one of the reasons photo quotes can only give a ballpark figure — the species matters.
3. Root Spread
Some trees, particularly figs, coral trees, and certain eucalyptus varieties, develop extensive surface roots that spread well beyond the stump itself. If you want those surface roots ground down as well (common when you’re planning to turf or pave the area), it adds time and cost to the job.
4. Site Access
If the stump is in an open front yard with clear access from the street, it’s straightforward. But many properties in the Illawarra have narrow side passages, steep blocks, retaining walls, or stumps tucked behind fences. Tight access stump grinding requires compact equipment and sometimes hand-fed grinders that fit through gate openings as narrow as 700mm. This adds time and a modest surcharge to the job.
5. Number of Stumps
Having multiple stumps ground in a single visit is more cost-effective per stump than booking them individually. The setup and travel time is the same whether you have one stump or five, so the per-stump rate drops when you bundle them together.
6. Proximity to Structures and Services
Stumps close to fences, retaining walls, driveways, or underground services (water, gas, electrical) require extra care. The operator may need to adjust grinding depth and angle, or hand-dig to confirm service locations before starting. This careful work takes more time but protects your property.
Stump Grinding vs. Stump Removal: Which Do You Need?
These terms get used interchangeably, but they’re actually two different things.
Stump grinding uses a machine with a rotating carbide-tipped wheel to chip the stump and its major surface roots into mulch, cutting 150–250mm below soil level. The lateral root system stays in the ground and decomposes naturally over several years. It’s faster, cheaper, and far less disruptive to your yard.
Stump removal (also called stump extraction) involves digging out the entire stump and root ball, usually with an excavator. It leaves a large hole, damages surrounding lawn and garden, and costs significantly more. Full extraction is only necessary for building foundations, pool construction, or deep excavation where no organic material can remain underground.
For the vast majority of residential jobs — whether you want to lay turf, plant a new tree, build a garden bed, or just get rid of an eyesore — stump grinding is the right choice.
What’s Included in a Stump Grinding Quote
When you get a quote from Southside Stump Grinding, here’s what’s covered as standard:
- Grinding the stump to 150–250mm below soil level (deeper grinding available on request for construction or paving projects)
- Grinding visible surface roots within the immediate stump area
- Wood chip mulch left on site — backfilled into the hole with excess available for garden beds
- Site cleanup — the work area is left tidy
- Free on-site quoting with no call-out fee and no obligation
Stump grinding produces a pile of wood chip mulch roughly four to six times the volume of the original stump. Most customers choose to backfill the hole and spread the excess around the garden. If you need the mulch removed entirely, that can be arranged and will be quoted separately based on volume and trailer access.
If you need the area ready for turf or paving, you’ll want to top up the backfilled hole with topsoil after a few weeks, as the mulch compacts and settles over time.
How to Get an Accurate Quote
The quickest way is to call or text Luke on 0413 655 655 with a photo of the stump. Include something for scale — a shoe, a tape measure, or even a can of drink next to the stump — so the diameter can be estimated. A rough quote can often be given from photos alone.
For an exact price, a free on-site inspection takes 10–15 minutes. During the visit, Luke assesses:
- Stump diameter and timber species
- Root structure and spread
- Proximity to fences, walls, or underground services
- Access path for the grinder
Quotes are valid for 30 days. Most jobs in Wollongong and the Illawarra can be scheduled within a week of accepting the quote.

Frequently Asked Questions
Will the stump grow back after grinding?
No. Stump grinding removes the stump and the crown of the root system, which eliminates the tree’s ability to produce new growth. Some species like coral trees and poplars can produce sucker growth from lateral roots beyond the grinding zone, but these are surface-level shoots easily treated with a broadleaf herbicide or removed by hand. They are not a new tree regrowing. True regrowth from a properly ground stump is extremely rare.
How long does stump grinding take?
Most residential stumps take between 30 minutes and 2 hours, depending on the species, diameter, and root structure. Small softwood stumps can be done in under 30 minutes. Large hardwood stumps with extensive roots can take a full morning. Luke will give you a time estimate along with the quote so you know what to expect on the day.
Do I need to call Dial Before You Dig?
It’s recommended. If the stump is anywhere near underground services (water pipes, gas lines, electrical conduits, or telecommunications cables), calling Dial Before You Dig on 1100 before the job is free and helps everyone work safely. If the stump is within 500mm of a known service, the operator may hand-dig to confirm the location before grinding.
Can you grind stumps in tight spaces or on steep blocks?
Yes. Tight access work is one of the most common requests in the Illawarra, where many older properties have narrow side passages, steep driveways, or stumps behind fences. Compact machines fit through standard gate openings as narrow as 700mm. For extremely tight situations, smaller hand-fed grinders can reach stumps in courtyards, between buildings, or on steep terrain.
