Tree Removal
Whole trees taken down, from a backyard camphor laurel to a spotted gum leaning over a Merewether roofline.

A stump grinder is a wheel of carbide teeth spinning at high speed, swept side to side across the stump, taking a few millimetres at a pass. It turns the stump and the top of the root plate into chip. It does not pull anything out of the ground and it does not remove the lateral roots that run out under your lawn — those are left to rot down, which they do over several years.
That is the right answer for the great majority of residential jobs. If you want to turf over the spot, plant a shrub near it, lay pavers or just stop tripping on it, grinding is faster, cheaper and far less destructive than digging the stump out.
When grinding is the wrong answer
If a slab, footing, pool shell or retaining wall is going in over the top, the engineer will want the root plate gone, not ground. If the stump is a sewer or stormwater problem — common with fig and camphor laurel on the older Hamilton, Islington and Mayfield blocks — the roots themselves are the issue and grinding the crown does not touch them. And if the tree is a vigorous suckering species on a small block, the regrowth may be more annoying than the stump was. Those cases are covered on the stump removal page.
Ground conditions around Newcastle
Sand is easy and fast. The coastal and dune country around Stockton, Fern Bay, Redhead and Blacksmiths grinds quickly, though a wet sandy hole backfills itself as you go.
The heavy clay through Charlestown, Cardiff, Kotara and the ridges behind Lake Macquarie is slower, holds water afterwards and needs the hole properly backfilled or you end up with a sump in the lawn.
The alluvial flats at Maitland and along the Hunter River grind easily but often hide buried debris — old fence wire, bricks, flood-deposited rubble — and a grinder tooth hitting a brick is an expensive noise. On old mining ground around Cardiff and Wallsend, filled subsidence hollows can also hide rubble.
Wherever the stump is, the other hazard is services. Grinding blind into a stump means grinding blind into whatever is beside it, and gas, water, telecommunications and irrigation lines all end up close to trees. Dial Before You Dig and a look at your own irrigation plan before the grinder arrives is cheap insurance.
Pricing and booking
Stump grinding is priced on stump diameter, how far below grade you want it, access and what happens to the chip. Several stumps in one visit are much cheaper per stump than one at a time, because a large share of the cost is getting the machine to your property. The cost guide sets out how that works.
Call (02) 4071 2525 for a free quote. If the tree is still standing, book the removal and the grinding together so the stump can be cut at the right height for the grinder — the removal process page explains why that matters. Technical detail on grind depth and root behaviour is on the stump grinding explainer.

FAQs
Frequently asked questions
How deep does stump grinding go?
Typically 200 to 400 millimetres below the surrounding surface, which is enough for turf, garden beds and most paving. Deeper is possible where something is being built over the top, but it costs more and it is limited by what is in the ground. If footings, a pool or drainage are going in, full excavation is usually the better answer.
Does grinding kill the roots?
It kills the stump and the crown of the root system, and most species then die off because nothing is left to produce leaves. Suckering species are the exception. Camphor laurel, privet, poplar and some wattles will throw shoots from severed lateral roots for a season or two, and those need to be knocked over as they appear.
What happens to the grindings?
They make a large pile of coarse chip mixed with soil, and there is always more than people expect — a decent stump produces a mound roughly twice its own volume. It can be raked back into the hole and topped with soil, spread through garden beds as mulch, or carted away. Carting is a separate charge because of the weight.
Can the grinder get into my backyard?
Usually. A narrow-access grinder fits through a gate of about 750 to 900 millimetres, which covers most Newcastle side paths. Stairs, steep slopes and very soft ground are the limits. If the only route is through the house, or the stump sits on a retaining wall, tell us on the phone — that changes the machine and the price.
