How deep the grind needs to go depends on what is going over the top.

Central Coast Tree Services connects the Central Coast and the Central Coast property owners with qualified, insured local arborists for stump grinding and related tree work. Tell us what the tree is doing and we'll match it to an operator who covers your suburb — free call, no obligation.

How deep is deep enough

It depends entirely on what's going over the top. For turf, 150–200mm below grade is generally fine. For paving, a slab or footings, it needs to go deeper and the major surface roots need chasing out too — otherwise you get settlement as the timber breaks down underneath.

Say what you're planning before the quote. Re-grinding a stump because the first pass was set for lawn is an avoidable second visit.

Palms are a different job

Cocos and bangalow palm stumps are fibrous rather than woody. They grind easily but produce a wet, stringy spoil that doesn't compost down like hardwood chip, and the hole tends to want backfilling with clean soil rather than the grindings.

Services, sand and what stops a grinder

Irrigation, gas, comms and pool plumbing all live shallower than people expect, and sandy coastal soil hides them well. A Dial Before You Dig enquiry is cheap. So is pointing out where your pool pipework runs before the machine starts.

Indicative pricing

Where this job typically sits. Access is usually a bigger cost driver than size.

JobIndicative priceWhat moves it
Small tree removal (under 10m)$500 – $1,200Ornamentals, young palms and small natives with room to work around them.
Medium tree removal (10 – 20m)$1,200 – $2,800The standard suburban job. Access moves this number more than height does.
Large tree removal (20m+)$2,800 – $8,000+Mature blackbutt, spotted gum or Norfolk pine, usually dismantled in sections.
Palm removal$250 – $1,200Cocos and bangalow palms — no real wood, so cheap unless the crown must come out in pieces.
Tree trimming / pruning$300 – $900Clearance off a roof, deadwooding or a crown reduction. Averages around $425 on this coast.
Stump grinding$150 – $500Priced on diameter and access. Expect a minimum callout of roughly $180 – $220.
Emergency / after-hours callout$500 – $3,000+Storm make-safe. What it costs depends on what the limb is resting on.
Arborist report (AQF5)$400 – $700Typically around $450. Required for a Private Tree Works Application and most consents.

Prices are indicative only. Every tree is different — access, species, what's underneath it and how far the chipper has to walk all move the number. You get a fixed written quote after an on-site assessment.

Stump Grinding — common questions

How much does stump grinding cost?

Usually $150 to $500 per stump, set by diameter and how close it sits to services, structures or a retaining wall. Several stumps in one visit drop the per-stump price because the machine is already there.

How deep does the grinder go?

Typically 200–300mm below grade — enough to turf or plant over. If you plan to pour, pave or build on the spot, say so up front, because that needs the stump and structural roots removed rather than ground down.

Can every stump be ground?

Not always. A stump tight against a wall, a fence footing or shallow services may need hand excavation instead, and a stump on a steep slope can be unreachable for a wheeled grinder. Worth flagging when you ask for the quote.
