Buildfix restumping and reblocking: what to know

Grounded in Buildfix's own published site. General information, not advice for your specific property.

A neutral look at Buildfix's "stump lifting" approach to restumping and reblocking, drawn from Buildfix's own published materials: what it is, how Buildfix compares it to traditional restumping, and what Buildfix's own pricing pages say about cost.

"Buildfix" is one of the names homeowners search for directly when researching restumping and reblocking, so this page pulls together what Buildfix itself publishes about its approach, a resin-based method it markets as an alternative to traditional restumping, and what its own pricing pages do, and do not, say about cost. Remedial Building Help does not provide or resell Buildfix's services; this is independent, informational content.

Who is Buildfix

Buildfix states, "For nearly 15 years, Buildfix has repaired 15,000+ homes and structures across Australia." Buildfix's own site lists its service areas as "Melbourne & regional Victoria, Sydney & regional NSW, Brisbane & South East Queensland, Canberra & ACT." It markets stump lifting as its own name for a resin-based alternative to full restumping, built around a product it calls GeoPoly resin.

What Buildfix calls stump lifting

Buildfix defines its own method plainly: "Stump lifting is a non-invasive alternative to restumping." Its materials say the stump itself is rarely the real cause of a sunken floor: "the stumps are almost never the problem," and that "When it shifts, the stump drops and loses contact with the bearer. A brand-new stump poured onto the same ground will do the same thing." Buildfix's process description states that "GeoPoly™ resin is injected through coin-sized holes around the affected stumps," expanding to "fill voids, compact weakened soil, and gradually lift each stump back into firm contact with the bearer above," rather than digging the old stump out and pouring a new one.

Buildfix describes the job in stages: a free assessment, then "Small, coin-sized holes are drilled at precise intervals around the affected stumps," the resin injection itself, and "Laser levelling equipment tracks every millimetre of movement in real time" as stumps are brought back into contact with the bearer above. On duration, Buildfix states "Most stump lifting jobs are completed in a single day," adding that "Larger homes or more severe movement may take 2 days." Buildfix says, "Every stump lifting job is backed by a 20-year product and workmanship warranty."

How Buildfix compares stump lifting to traditional restumping

Buildfix's own site draws this contrast between what it calls traditional restumping and its stump lifting method. This is Buildfix's own framing of its product against the generic alternative, not an independent finding; for this site's own neutral, method-by-method comparison that includes restumping and reblocking cost and timeline figures from published Australian guides, see underpinning, resin injection and restumping compared.

Why Buildfix says stump lifting addresses the ground, not just the stump

Buildfix's own argument for its method is that restumping can fix the symptom while leaving the cause in place: in Buildfix's words, "A brand-new stump poured onto the same ground will do the same thing" if the ground beneath it stays unstable. That is Buildfix's own case for its product against the generic alternative, not an independent engineering finding, and it does not mean every restumping job leaves a cause untreated; a structural engineer's own diagnosis of why the stumps moved is what should decide the method, not a provider's marketing comparison.

Where stump lifting fits, and where it doesn't

Stump lifting, like traditional restumping and reblocking, is remedial work for homes built on timber or concrete stumps rather than a slab. It is a different job to underpinning in the excavation sense, mass concrete underpinning, screw piles, or resin injection into a slab's own footing, which address slab-on-ground and strip-footing homes instead. See underpinning methods explained for how those three slab-focused methods compare to each other.

What Buildfix's pricing pages say about cost

Buildfix's pricing page states, "Structural repair costs sit between $2,000 and $16,000 depending on the service and the size of the job." That range sits alongside six named services with their own dedicated pricing guides: Underpinning, Wall Crack Repair, Damp Proofing, Floor Pier Repairs, Concrete Relevelling and Remedial Wall Ties. Stump lifting does not have its own card in that list of six, but Buildfix's stump-lifting FAQ does point to a price: "For an approximate price range and what's involved, see the floor pier repairs pricing guide," linking to Floor Pier Repairs, which is one of the six. That guide states, "The approximate floor pier repairs cost sits between $4,000 and $8,000 depending on how many piers have dropped and how far the floor has sunk." The same guide separately states, "Restumping can run $25,000 to $35,000 and takes weeks," its own comparison figure against the generic alternative, not a figure this directory has independently verified.

That $25,000 to $35,000 restumping figure is higher than this site's own cost guide, which puts a full restump at $5,000 to $20,000, reaching $10,000 to $30,000 for larger or high-set homes with more stumps to replace. Neither figure is wrong on its face; they come from different sources counting different things, which is exactly why a written, itemised quote for your own property is the only reliable number. For restumping and reblocking price ranges drawn from published Australian guides, independent of any single provider, see the underpinning cost guide and underpinning, resin injection and restumping compared.

Credentials and licensing, as Buildfix describes them

Buildfix's own site footer publishes "ABN: 90 169 195 411 | Builders Licences: 294990C, QBCC 15114268, CDB-U 100816." Its about page separately states that "Buildfix holds builder's licences in NSW, VIC, and QLD and is a registered member of Master Builders," and that "All Buildfix structural engineers hold current registration with Engineers Australia." These are Buildfix's own published details about itself, not an independent licence check.

Before you engage any provider

Whichever company you are considering, including Buildfix, confirm current licensing, insurance and a written, itemised scope directly with them before agreeing to work, and get an independent structural engineer's assessment first if the cause of movement is not already established. See how to choose a remedial contractor for the questions worth asking, or our directory to compare quotes from other listed restumping, reblocking and underpinning providers.
