A strata specialist is a licensed building practitioner who diagnoses and repairs structural and waterproofing defects in strata schemes, rather than carrying out general maintenance or renovation work. In New South Wales, choosing a strata specialist who is registered under the Design and Building Practitioners Act is essential for compliant, insurable repairs.
If you are a strata manager or committee member weighing up quotes for defect repairs, you have probably noticed that not every contractor calls themselves the same thing. General builders, waterproofers, and strata specialists all operate in overlapping territory, but the differences matter once compliance, documentation, and liability come into play.
This guide explains what a strata specialist actually does, why licensing matters, and what to look for when choosing one for your scheme.
A strata specialist, sometimes called a strata remedial specialist, focuses specifically on diagnosing and repairing defects in existing strata buildings, things like cracking, concrete spalling, water ingress, and balustrade movement, rather than new construction or cosmetic renovation. The “strata” part matters because defects in a scheme rarely affect a single lot. They often involve common property, which means a strata specialist needs to understand shared responsibility, owners corporation decision making, and the documentation strata buildings require.
This is different from a general handyman or a single-trade contractor. A strata specialist typically manages the diagnosis, the compliance documentation, and the repair as one coordinated process.
The scope of work usually includes:
For older strata buildings in particular, several defects often surface around the same time. A strata specialist can assess the whole scheme rather than treating each issue as a separate, unrelated job.
In New South Wales, remedial work involving structural elements or waterproofing on a strata (Class 2) building is regulated under the Design and Building Practitioners Act 2020. This means a strata specialist carrying out the work needs to be a registered building practitioner, and the project needs a documented, compliant design rather than an informal repair.
This is not just a box ticking exercise. An unlicensed or poorly documented repair can create ongoing liability for an owners corporation, and may not satisfy the requirements of insurers, certifiers, or NCAT if a dispute arises later. Engaging a DBP Act registered strata specialist means the project is assessed, scoped, and documented properly from the outset, giving the committee the paper trail it needs.
A general builder can handle a wide range of construction and renovation work, but may not have the specific licensing or diagnostic experience the Design and Building Practitioners Act requires for strata defect repairs.
A waterproofer typically addresses membrane and sealing failures on their own, without necessarily covering the structural side of a defect, such as concrete spalling or balustrade movement.
A strata specialist sits across both, diagnosing structural and waterproofing defects together, and delivering the compliance documentation a strata scheme specifically needs. For committees, this usually means fewer contractors to coordinate and a single point of accountability for the whole repair.
A few questions worth asking before engaging anyone:
A strata specialist who can answer all of these clearly is generally a safer choice for a committee that will need to justify the decision, and the documentation, later on.
Choosing the right strata specialist affects more than the immediate repair. Documentation from a properly licensed project supports insurance claims, protects the owners corporation if a dispute goes to NCAT, and forms part of the record buyers and their lawyers will review at resale.
It can also change the cost and disruption of the work itself. Addressing defects lot by lot as they appear is often more expensive over time than engaging a specialist to deliver a coordinated strata remedial services programme across the affected part of the scheme.
Do I need a licensed strata specialist for remedial work in NSW?
Yes, for structural or waterproofing related defects in a strata (Class 2) building, the practitioner needs to be registered under the Design and Building Practitioners Act.
Is a strata specialist the same as a strata manager?
No. A strata manager handles the administrative and governance side of a scheme, meetings, levies, and compliance paperwork. A strata specialist is a licensed building practitioner who diagnoses and repairs physical defects. Many jobs involve both working together, but they are different roles.
What is the difference between a strata specialist and a builder?
A general builder may not carry the specific licensing or strata-specific documentation experience the Act requires. A strata specialist is registered for this work and manages the diagnosis, documentation, and repair as one process.
How do I verify a strata specialist’s licence?
Ask for their Building Practitioner licence number and check it against the NSW licence verification register before engaging them.
If your scheme is weighing up options for defect repairs, the safest first step is engaging a properly licensed strata specialist for a documented assessment rather than an informal quote.
