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.
- Concrete spalling and structural repair
- Waterproofing and rising damp barriers
- Planter box membranes and drainage
- Facade restoration and render repair
- Cavity flashing and lintel replacement
- Window and door replacement
- Building diagnostics and reporting
- Bathroom and kitchen upgrades in units
- Common area refurbishment
- Preventative maintenance programs
Questions committees and managers ask
Who pays for common property repairs in a NSW strata scheme?
The owners corporation. Section 106 of the Strata Schemes Management Act 2015 places a strict duty on it to maintain and repair common property and to renew or replace common property fixtures. Cost or difficulty is not a defence. An owner can recover reasonably foreseeable loss caused by a breach of that duty.
What causes concrete spalling in an apartment building?
Water reaches the steel reinforcement inside the concrete and it corrodes. Rust occupies more volume than the steel it replaces, so it pushes the concrete off from the inside. That is why spalling shows first as cracking and bulging on balcony edges and soffits, then as pieces falling away.
Can any builder work on an apartment building in NSW?
No. Building work on class 2 buildings must be carried out by a registered building practitioner who makes compliance declarations under the Design and Building Practitioners Act 2020. Vertex holds registration BUP0002293, current to July 2030. You can confirm any builder's registration yourself on Verify NSW.
How long do remedial works take on an occupied building?
It depends on access more than on the repair. Scaffold, exclusion zones and resident notice periods usually set the program. We scope in stages so residents keep access to their homes, and we write the program into the quote the committee reviews.
Do we need an engineer's report before quoting?
Sometimes. If a defect is structural, or if the cause is not visible, a building consultant or structural engineer should diagnose it before anyone prices a repair. We will tell you when a report is needed rather than quoting a patch over an unknown cause.
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.
