Reliable Repairs Backed by Experience
We’ve built our reputation on doing repairs properly—the first time. Whether you’re dealing with ageing materials, water leaks, or concrete corrosion, we take the time to assess the problem, recommend a solution, and carry it out to the highest standard.
As a family business with over 168 years of building experience in Australia—spanning three different centuries—we understand the value of workmanship that stands the test of time. Having been in the same local area for around 120 years, much of our work comes through word-of-mouth, which we see as a reflection of the trust we’ve earned over generations.
From small residential jobs to larger remedial work, we focus on providing cost-effective repairs that won’t let you down in the long run. We know what’s worth fixing, what needs replacing, and how to make it all blend in with the existing structure so your property looks good as new. Get in touch to talk through your project—we’re always happy to help.


Fixing Concrete Cancer
If you’ve noticed rust stains, cracking or spalling in your concrete, it could be concrete cancer. We’ll assess the damage and treat it properly to prevent further spread and restore strength to the area.
