Restumping a house in Gold Coast costs $7,850–$25,500 for most timber-subfloor homes, or $175–$625 per stump installed. A 2–3 bedroom post-war chamferboard or weatherboard cottage on 15–25 stumps costs $7,850–$15,700 (typically $11,750), while a standard 3–4 bedroom Queenslander or high-set timber home on 25–40 stumps runs $12,750–$25,500 (typically $17,650). Partial restumping and spot relevelling of 5–10 stumps costs $2,150–$5,500 (typically $3,525).

Queenslander and post-war timber homes in Gold Coast face three relentless subfloor pressures: subterranean termites, wet-dry reactive clays, and tall pier heights on sloping blocks. High-set, sloping-site, low-clearance or two-storey restumping and relevelling ranges from $19,600 to $39,200 (typically $27,450). For brick or slab homes with foundation movement, concrete underpinning costs $1,175–$2,750 per pin / m (typically $1,825), bearer or joist replacement adds $120–$335 per m (typically $205/m), and Queensland building approval (Form 15 / Form 16 engineering and certifier fees) adds $1,175–$3,725 per job (typically $2,150).

Gold Coast Restumping Costs: Queenslanders, Steel Columns & QBCC Rules

Restumping in Gold Coast spans everything from low-set post-war cottages to high-set Queenslanders, and the quote turns on the subfloor height, the stump material and what the QBCC-licensed contractor and the certifier have to sign off:

High-Set Queenslanders on Sloping Blocks: Steeply sloping blocks and high-set subfloors (often 1.8m–3.0m+ high) require hot-dip galvanised steel columns (75×75mm or 89×89mm SHS) or precast concrete columns with engineered tie-down bolts and wind bracing ($235–$625 per steel stump, typically $410; or $12,750–$25,500 for a standard 3–4 bed restump, and $19,600–$39,200 for complex, steep or two-storey lifts).
Post-War Chamferboard & Hardwood Cottages: 1940s–1960s 2–3 bedroom cottages on 900mm–1,500mm concrete or timber stumps. Full restumping typically costs $7,850–$15,700 (around $11,750 typical) using precast concrete stumps ($175–$470 per stump, typically $315) or galvanised steel posts.
Reactive Clay Blocks: Reactive clays shrink in dry spells and swell after heavy rain. Adjustable steel stumps ($235–$625/stump) and deeper bored piers prevent seasonal floor crowning, while slab/brick homes on these soils use concrete underpinning ($1,175–$2,750 per pin / m, typically $1,825).
QBCC Licensing, Form 15/16 Certification & Termite Barriers: Any structural restumping or underpinning over $3,300 in Queensland must be carried out by a contractor holding an appropriate QBCC licence (Builder Restricted to Structural Landscaping / House Raising & Restumping, or Open/Low-Rise Builder), with QBCC Home Warranty Insurance on residential contracts over $3,300. You also need a private building certifier, RPEQ structural engineer design (Form 15) and inspection certificate (Form 16) ($1,175–$3,725 per job), plus AS 3660.1 physical termite protection (ant caps or collars) on all new stumps.

What Affects Restumping & Reblocking Costs in Gold Coast

Low-set vs high-set Queenslander height

Low-set post-war cottages on 600mm–1,200mm piers cost $7,850–$15,700 (2–3 bed) or $12,750–$25,500 (3–4 bed). High-set Queenslanders on 2.4m–3.0m+ columns or steep blocks require engineered steel columns, deeper bored footings and bracing ($19,600–$39,200).

Hot-dip galvanised steel vs concrete stumps

Precast concrete stumps cost $175–$470 per stump (typically $315) and suit heights up to ~1.8m. Hot-dip galvanised or adjustable steel columns ($235–$625 per stump, typically $410) are preferred for tall high-set subfloors, build-under renovations and reactive clay blocks.

Termite & wet-rot damage in hardwood bearers

Subterranean termites and wet rot frequently hollow out old hardwood bearers and joists above the stumps. Replacing or sistering damaged subfloor timber adds $120–$335 per linear metre (typically $205/m).

Council Character & Flood Overlays

Homes in a character or flood overlay can carry conditions on subfloor enclosures, pier design and height — RPEQ engineering (Form 15), soil testing and private certifier building approval add $1,175–$3,725 per job (typically $2,150).

Under-house concrete slabs & battens

Where a high-set home has an existing concrete slab poured between the old stumps plus laundry plumbing and perimeter battens, cutting concrete pockets around each stump and disconnecting/reconnecting rigid plumbing adds labour over an open-earth subfloor.

Slab & brick-veneer subsidence

Where a brick-veneer or slab home in Gold Coast has cracked due to reactive clay shrinkage or tree roots, concrete underpinning runs $1,175–$2,750 per pin / m (typically $1,825).

How to Save Money on Restumping & Reblocking in Gold Coast

Verify your contractor's QBCC licence number and confirm QBCC Home Warranty Insurance is lodged on any Gold Coast restumping contract over $3,300.

Ensure your quote explicitly includes RPEQ engineer Form 15 design, Form 16 site inspection certification and private certifier building approval ($1,175–$3,725) — uncertified restumping causes major issues when selling in Gold Coast.

If you plan to build in underneath your Queenslander later, tell your restumper now so the RPEQ engineer spaces the new steel columns ($235–$625/stump) to suit future room layouts and legal 2.4m ceiling heights.

Insist on hot-dip galvanised steel stumps (or concrete stumps with stainless/galvanised tie-downs) and compliant AS 3660.1 ant caps on every pier to stop subterranean termites bridging into your hardwood bearers.

Replace all ageing timber or spalling concrete stumps in one project ($7,850–$15,700 for a 2–3 bed cottage) rather than patching 5–10 stumps ($2,150–$5,500) and paying engineering and certifier fees twice.

Frequently Asked Questions — Restumping & Reblocking Cost in Gold Coast

How much does it cost to restump a Queenslander or house in Gold Coast?

Restumping a 2–3 bedroom post-war cottage or smaller Queenslander in Gold Coast (15–25 stumps) costs $7,850–$15,700 (typically $11,750). A standard 3–4 bedroom Queenslander or high-set timber home (25–40 stumps) costs $12,750–$25,500 (typically $17,650). Complex, steep-slope, low-clearance or two-storey restumping and relevelling runs $19,600–$39,200 (typically $27,450).

How much does restumping cost per stump in Gold Coast?

In Gold Coast, precast concrete stumps cost $175–$470 per stump (typically $315), hot-dip galvanised or adjustable steel stumps cost $235–$625 per stump (typically $410), and treated hardwood timber stumps cost $155–$390 per stump (typically $255), supplied and installed.

Do I need council or certifier approval to restump a house in Gold Coast?

Yes. In Queensland, replacing more than a minor number of stumps is assessable building work requiring building approval from a licensed private building certifier, backed by an RPEQ structural engineer's design certificate (Form 15) and final inspection certificate (Form 16). Allow $1,175–$3,725 (typically $2,150) for engineering, soil testing and certification.

Should I use steel or concrete stumps in Gold Coast?

Precast concrete stumps ($175–$470/stump) are durable and cost-effective for low-set to mid-set Gold Coast cottages up to ~1.8m clearance. Hot-dip galvanised steel columns ($235–$625/stump) are stronger and slimmer for high-set Queenslanders above 1.8m, sloping blocks, and reactive clay sites where adjustable top plates allow easy future relevelling.

How much does concrete underpinning cost in Gold Coast?

Concrete underpinning for subsided slabs or strip footings in Gold Coast costs $1,175–$2,750 per pin or linear metre (typically $1,825 per pin / m), plus $1,175–$3,725 for RPEQ structural engineering, soil testing and building certification.
