Andersal is a leading Sydney based building rectification contractor, specialising in facade and structural restoration, concrete repairs and external waterproofing.

We have been providing remedial solutions since 1987. The company is run by highly experienced engineers and licensed builders. We have a dedicated team where many of our staff have been with the company for over 10, 20 and 30 years!

We know our clients want peace of mind and a good overall experience when choosing a building contractor. Our project managers strive to achieve a smooth experience and we are pride ourselves on the high levels of customer satisfaction we receive.

Andersal is organised to efficiently manage contracts from $15K to multi-million-dollar projects. We are however, not resourced to carry out minor repairs to private residences or internal waterproofing.

In addition, to government and industrial contracts, Andersal completes many commercial and strata projects each year. Andersal has many long-term relationships with Strata Managers and Facility Managers who regularly recommend Andersal to provide repair quotes.

Andersal enjoys the support of many consulting engineers and builders who often select Andersal as best value for the client and as part of the process, look for contractors who have a credible track record and demonstrate the skill required for the project.
