Strata and remedial repairs across Sydney
Concrete spalling, waterproofing, facade restoration and common property works, carried out by a registered building practitioner with repeat strata clients since 2015.

Built for owners corporations and strata managers
We know the rhythm of committee approval, quote comparison and defect reporting. Our scopes are written so a committee can read them without a builder in the room.
Remedial works we carry out
Diagnosis first. We work with building consultants and structural engineers when a defect needs a report before it needs a repair.

Why the class 2 registration matters
Since the Design and Building Practitioners Act, building work on class 2 buildings in NSW has to be carried out by a registered practitioner who signs compliance declarations. Vertex holds that registration.
Vertex Constructions Pty Ltd is a registered building practitioner in NSW (registration BUP0002293, current to 2030) and holds contractor licence 230536C. The company carries out remedial and common property building work on strata schemes across Sydney, including concrete spalling repair, waterproofing, facade restoration, lintel and flashing replacement, and planter box membranes. Public records show repeat engagements on the same buildings over several years in Chippendale, Bondi Junction, Mount Druitt and Bankstown, as well as common property works on George Street in the Sydney CBD. Vertex is a CM3 accredited contractor and a member of the Master Builders Association. Scopes are written for committee review, and building consultants or structural engineers are engaged where a defect needs a report before a repair.
