It matters when your home breaks. It matters to fix it right.

Australia’s leading experts in non-invasive structural and foundation repair.

Are you seeing wall cracks appearing and getting wider? Or noticing your floor starting to slope near a corner and doors beginning to jam? Maybe your bricks are crumbling near the ground. These can be signs of a structural issue, and they’re the exact problems we fix for homeowners every single day.

With Buildfix’s non-invasive solutions, fixing your home doesn’t have to mean digging up the garden or knocking down walls. In most cases, you won’t have to move out or even move the furniture. Using advanced structural repair technology, like our GeoPoly™ resin injection underpinning solution, we target the problem directly at its source through small, coin-sized holes. No weeks of upheaval or major rebuild bill—you could save thousands.

Every job is backed by a written 20-year warranty. We send one of our structural engineers out to assess your home for free. When you’re ready to go ahead, our repair team can usually be there a few weeks later, with most jobs done in a day or two.

Over 15,000 homes and structures repaired across Sydney, Melbourne, Brisbane and Canberra. Get in touch today for a FREE structural assessment—if nothing else, you’ll have peace of mind.

Why homeowners choose Buildfix:

Non-invasive technologies. GeoPoly™ injections stabilise the ground. HelicalBar™ restores strength through small slots between bricks. DampBlock™ creates an invisible barrier against rising damp. Floors lifted. Cracks repaired. Walls drying out. Most jobs done in a day or two.
All work guaranteed. Your repair is backed by a 20-year product and workmanship warranty. If the same structural issue returns in the area we repaired, so do we—at no cost to you.
Fixed price. Nobody likes surprises, especially when they mean paying hundreds, if not thousands, more than you were quoted. That’s why, when we give you a quote at Buildfix, it’s fixed price. No extra per-kilo charges at the end. No surprise costs. If your job goes over, it’s on us.*
Trusted advice. Our approach is different. We lead with structural engineers. It’s not the industry norm, but after 15,000+ jobs, we’ve learnt a thing or two. Misdiagnosing a crack or treating the symptom rather than the cause helps no one. We aim to get it right the first time. Every time.

*A quoted price is fixed only for the scope of work agreed in that quote. It may increase if you ask for changes to that scope, or request a variation, after the agreement is in place. Any price shown on this website or in Buildfix marketing material is a guide only, not a quote or a fixed price for any service. Every job is priced on its own site conditions, scope and requirements.
