More Questions...

How long will it take for my walls to dry after damp proof treatment?
We employ our damp proofing solution, DampBlock™, to counteract the effects of rising damp in your walls by blocking capillaries, reducing the walls ability to draw moisture upwards. After this process, the existing damp in your walls will generally take 6-12 months to dry out.
After the damp proofing process, your walls will start to dry. However, this can result in natural salt crystallisation and residual dampness on the surface. To prevent the surface plaster from deteriorating and the appearance of damp, an application of a salt-blocking solution is recommended, which we are happy to assist with and discuss during your assessment.
Certainly not. DampBlock™ is non-hazardous and completely odourless, allowing you and your family to stay at home while we work.
Buildfix has successfully completed well over 10,000 projects across Australia over the past decade. This includes mostly residential projects, as well as some commercial and strata buildings.
Absolutely. We proudly offer an industry-leading, transferable 20-year warranty on our products and workmanship, which ensures your peace of mind for years to come and adds value to your property, even if you decide to sell it in the future.
Yes, our DampBlock™ is environmentally safe and poses no harm to the surroundings.
Yes, effective damp proofing can enhance the structural integrity of your property, prevent health hazards due to mould and ultimately improve the property’s market value and appeal to potential buyers.

More Questions...

How do I know if my home needs wall crack repairs?
If you’re noticing cracks in your walls, particularly near doors and windows, or if they’re growing over time, it’s likely you have a structural issue. Contact us for a free assessment and we’ll diagnose the problem.
No, not at all! Unlike traditional methods, our approach is non-invasive. We use HelicalBars™ and other advanced technologies to fix the cracks without any wall demolition.
The cost of repairing wall cracks depends on the severity of the damage. Most residential repairs range from $5k to $20k. We offer a free assessment and provide a fixed quote with no hidden fees.
In addition to wall crack repair, we provide subsidence repair, slab jacking, rising damp solutions, and more. We ensure your home is not only structurally sound but looks great too.
Absolutely! We back all of our wall crack repairs with a 20-year warranty.
