About Buildfix
Structural engineers for your home
One team. Assessment, repair, and warranty — all the same people.
Your home’s structural problems deserve more than a report and a referral. Buildfix structural engineers lead every project from the first inspection to the final sign-off — and the same company that diagnoses the issue is the one that repairs it, manufactures the products, and guarantees the result for 20 years.
That’s not how this industry normally works. But after 15,000+ homes, it’s how it should.

How structural repairs usually work — and why it frustrates homeowners
The traditional model asks you to project-manage your own home repair.
Something cracks. A door sticks. The floor feels wrong. So you call a structural engineer. They inspect, write a report, and hand you a list of recommendations. Good advice, genuinely — but now you need someone to carry it out.
So you call a builder. The builder quotes the job but hires subcontractors for the technical work. Those subcontractors have never seen the engineer’s report. The engineer has no control over the execution.
If the repair doesn’t hold, the builder points at the engineer’s design. The engineer points at the builder’s workmanship. And you’re left in the middle, paying twice for a fix that should’ve worked the first time.
That’s the model most homeowners walk into. Not because anyone’s doing the wrong thing — but because the setup itself has limitations. The people who understand the problem aren’t the ones fixing it. The people fixing it didn’t diagnose it. Nobody owns the whole outcome.
Buildfix exists because that gap shouldn’t exist.
A structural engineer leads your repair from start to finish
Assessment, design, repair, and warranty — no handovers, no finger-pointing.
Structural engineers see things differently. Where a builder sees a crack, an engineer sees a load path — the way force travels through a wall, into a footing, down into the ground. That difference matters, because treating the symptom without understanding the load path is how repairs fail.
Structural engineers run the assessment, design the repair, and oversee the technicians who carry it out. The same team that identifies differential settlement in your foundation is the team that injects GeoPoly™ resin beneath it to lift and stabilise the ground. The same engineers who map a crack pattern across your brickwork specify exactly where HelicalBar™ reinforcement goes — then watch it installed.
No report handed to a stranger. No builder interpreting an engineer’s notes. No subcontractors who’ve never set foot in your house.
Straight answers.
Your first conversation is with an engineer, not a salesperson. No pressure. Just an honest assessment of what's happening and what it needs.
Right fix, right place.
Engineers pair the right technology with the right diagnosis. That means fewer materials, less disruption, and a repair that targets the actual cause — not just the visible damage.
Fixed properly, first time.
Every repair carries a 20-year product and workmanship warranty. If the structural issue returns, so do the people who fixed it.

The products used on your home are made by the same company repairing it
Most structural repair companies buy off the shelf. Buildfix builds the shelf.
In 2019, Buildfix acquired its own manufacturing facility. Not because making products sounded interesting — but because the products available on the market weren’t good enough.
Off-the-shelf foundation resins varied batch to batch. Imported wall reinforcement didn’t suit Australian masonry. Damp-proofing chemicals came with warranty fine print that made the guarantee meaningless. So instead of working around someone else’s product limitations, Buildfix started making its own.
Quality control.
Every batch is made to Buildfix specifications. No substitutions. No supply chain surprises.
Genuine guarantees.
The 20-year product and workmanship warranty means something when you control every ingredient. It's not a piece of paper backed by a supplier who may not exist in five years.
Lower costs for homeowners.
No supplier margins. No distributor mark-ups. The savings go straight to the quote — which is why homeowners regularly tell us Buildfix came in lower than expected.
Fixed pricing.
Because material volumes are known before the job starts, the price you're quoted is the price you pay. No per-metre surprises on the day.
Real homes. Real results.
