Fixing Your Wall Cracks
On the scheduled day, our technicians arrive and carry out the repair with care and precision. We cut targeted slots into the wall and install HelicalBars™ using high-strength structural grout. Each bar is securely bonded to the masonry, reinforcing the structure and restoring strength exactly where it’s needed most.
Final Touches & Clean-Up
With the HelicalBars™ installed, we restore the wall’s appearance by repointing mortar, filling cracks, and colour-matching the finished brickwork. For rendered or plastered walls, we blend the surface to ensure a smooth, uniform finish that looks as good as new. We finish by cleaning the area and leaving your home spotless, inside and out.

*Unlimited HelicalBars™ applies exclusively to residential customers only.
Does foundation repair fix wall cracks?
It’s a common but misguided belief that fixing your foundation will also repair cracked walls. While foundation work stabilises the ground, it doesn’t address the damage to the wall itself.
At Buildfix, our engineers take a holistic approach—assessing ground movement, structural cracks, and how the wall should look once restored. We often combine HelicalBars™ to reinforce the wall with GeoPoly™ resin injection to stabilise the foundation.
We also take care of the cosmetic repairs, including mortar repointing, crack filling, and smoothing plaster or render—so your home is structurally sound and looks its best.
Will the wall crack repair process be disruptive or messy?
Our method is designed to be quick, clean, and minimally disruptive. We use precision cutting tools with dust extraction to reduce mess. Some dust is unavoidable with plastered walls, but we protect your home and always leave the area clean. Most repairs are done with little to no interruption to your daily routine.
