Tree root removal cuts out roots that are lifting paving, cracking slabs or getting into stormwater pipes, using selective root pruning so the tree stays stable where possible. Tree Fox removes roots across Greater Adelaide and checks first whether the tree is regulated. Single-root jobs typically cost $280–$650; larger jobs with root barriers cost more.

Tree root removal in Adelaide is the call that comes after roots start lifting paving, cracking driveways, blocking stormwater, or pushing up against pool shells. It’s also the call that needs the most honest answer of any tree job we do: sometimes you can prune the offending root and keep the tree, sometimes you can’t, and sometimes the right answer is removing the tree itself rather than fighting the root system. We do all three, and we tell you up front which one your tree actually needs.
Why root work is its own scope
Cutting tree roots looks simple — it’s not. The risks sit on three sides:
- Tree stability. Cut the wrong root on the wrong species and the tree fails in the next strong wind. The structural roots — the buttress roots within the first 1–2m of the trunk — are doing the load-bearing job. Severing them is rarely safe even on a healthy specimen.
- Tree health. Roots are how the tree feeds. Cutting more than ~25% of the root mass on the windward side of a mature tree pushes it into stress decline; the symptoms show up 6–18 months later as crown dieback.
- Hidden services. Stormwater, sewer, gas, water, comms — all run through the same root zone you’re cutting. Locating services before excavation is part of the job, not an optional upgrade. Dial Before You Dig (1100) gets called on every excavation we do.
A root job done poorly produces three outcomes none of which the homeowner wanted: a dying tree, a failed tree, or a cut service line.
The problems we solve
Recurring Adelaide jobs:
- Surface roots lifting paving and pavers — common with established eucalypts, plane trees, and liquidambars in front yards. Selective root removal where the root isn’t load-bearing, plus root barrier installation to stop reinvasion.
- Driveway and slab cracking — a 100mm root under a thin concrete slab can lift it 30mm. Removal plus barrier plus slab reinstatement (separate trade — we coordinate, don’t do the concrete).
- Pool shell pressure — fibreglass and concrete pool shells are vulnerable to root encroachment from established trees within 4–5m. Selective root removal and barrier installation; sometimes the honest answer is removing the tree.
- Stormwater and sewer infiltration — fibrous roots find any joint or crack in old earthenware pipes (common in pre-1970s Adelaide housing stock). Plumbing scope to reline or replace; our scope is removing the root mass back to viable structural roots.
- Footpath and verge upheaval — usually involves a council-managed street tree. We can’t remove roots on a council tree; we can advise on the council process.
How Tree Fox handles a root job
- Site assessment. Identify the species, the root in question, what it’s lifting/blocking/threatening, and where the structural buttress roots are. Photograph and document.
- Tree health and stability call. Is selective root removal viable on this species without compromising the tree? Eucalypts, plane trees, liquidambars and most established broadleafs tolerate some root pruning if it’s away from the buttress zone. Some species (figs, willows, certain palms) do not.
- Service location. Dial Before You Dig (1100) lodged for the excavation area. Underground services marked before any cut.
- Excavation. Hand-dig or air-spade around the target root. We don’t trench across a root plate with a mini-excavator unless the tree is being removed anyway.
- The cut. Sharp pruning cut at the appropriate distance from the trunk — not torn or chopped. Wound dressing isn’t generally applied (modern arboriculture has moved away from it for most species).
- Root barrier installation (if appropriate). HDPE or copper-impregnated barrier installed against the cut face, oriented vertically to prevent reinvasion. Adds meaningful longevity to the fix.
- Backfill, reinstate, clean up. Surface restored to the level it should be at; soil compacted; any pavers re-laid. If concrete or paving needs proper reinstatement, that’s a coordinated trade.
Pricing context for root removal
Root work in Adelaide varies more than most tree services because access, services, and reinstatement all swing the price.
- Selective surface root removal, single root, accessible: $280–$650
- Multi-root removal with root barrier installation (e.g. 4–6m of pavers lifting): $650–$1,800
- Major root grinding adjacent to slab or pool: $1,200–$3,500+
- Stump and major root mass below grade: priced as part of stump removal
- Reinstatement (concrete, pavers) — coordinated separately with a paver/concreter; not bundled into the root price
What moves price: depth of excavation, root diameter, proximity to services, root barrier metres, and access for the air-spade or excavation gear.
When to call us vs the parent service
If your tree needs general pruning above ground — branches, deadwood, structural cuts — head to the parent tree pruning page. If you’re grinding a stump that’s already been cut, that’s stump grinding. If the right answer is removing the tree because the root problem isn’t pruneable, that’s tree removal. If the situation needs a written tree assessment for an insurance claim or council application, the arborist reports scope covers it. This page is specifically for surgical root work below or at ground level.
