Remedial works means repairing defects in the building fabric: spalling concrete, cracked render, failed sealant, leaking flashings, loose tiles or cladding. On a multi-storey building the repair itself is often small, and the cost of reaching it is not. Rope access lets technicians work down the façade from certified roof anchors, so many repairs can be done without full-height scaffolding. It does not suit every job, and this guide explains where the line usually sits.
Repairs that usually suit rope access
Rope access works best when the defects are spread across a façade and each repair can be carried out by a technician with hand tools and small equipment. Typical examples:
- Concrete spalling and exposed reinforcement. Breaking out loose concrete, treating the steel and reinstating the profile on balcony slab edges, columns and façade panels. See concrete cancer repair.
- Cracks in render and concrete. Opening, filling and sealing cracks, then protecting them with a suitable coating.
- Sealant and expansion joints. Cutting out failed sealant around windows and in movement joints and resealing. See sealant replacement and caulking.
- Flashings and cappings. Refixing, resealing or replacing flashings at window heads, parapets and roof junctions.
- Leak investigation. Inspecting the façade up close and water testing one area at a time to find where water gets in. See high-rise leak detection.
- Making the façade safe. Removing or securing loose render, tiles or panels after a storm or an inspection.
- Coatings after repairs. Painting repaired areas or the whole façade from the same access. See façade painting.
Because the same rigging reaches every level, several of these tasks can be grouped into one mobilisation. A repaint is often the point where a building gets its concrete repairs, sealant and anchor recertification done at the same time.
When rope access is not the right tool
Some remedial jobs are better done from scaffolding, a swing stage or an elevated work platform. A good contractor will tell you when that is the case. Common examples:
- Large areas of render, cladding or brickwork being removed and replaced, where heavy materials have to be stored and handled at height.
- Work that needs heavy plant, extensive demolition or temporary propping.
- Long jobs on one small area, where a fixed platform gives a better working position for weeks at a time.
- Buildings with no safe roof access or no anchors, until anchors are inspected or installed. See anchor point installation and certification.
- Low buildings where an elevated work platform can reach everything from the ground.
On many projects the answer is a mix: rope access for most elevations and a platform for one awkward area.
Who decides how the defect is repaired
For concrete cancer, structural cracking or recurring leaks, the repair method should come from an engineer’s or remedial builder’s specification, and the contractor carries it out. Rope access is how the crew reaches the defect. It does not change what the repair needs to be.
On Class 2 buildings (apartment buildings) in NSW, remedial building work is regulated under the Design and Building Practitioners legislation. For regulated work, a registered design practitioner prepares a regulated design and a building practitioner lodges documents on the NSW Planning Portal, unless the work is exempt or an emergency. Waterproofing and façade work are among the building elements covered. The NSW Government explains the rules on its remedial building work page. Your strata manager or engineer can confirm whether a particular scope is regulated.
Licensing also matters. In NSW you need a contractor licence to do residential building or trade work valued at more than $5,000 in labour and materials, including GST (NSW Government). Ask every contractor for their licence number and check that it covers the work being quoted. Our details are on the licences, insurance and safety page.
Planning a remedial scope by rope access
- Collect what you already know. Defect reports, residents’ leak complaints with dates, photos and any engineer’s report.
- Check the roof. Safe roof access and anchors with a current inspection tag. If they are out of date, they are inspected or recertified before the work starts.
- Get a close-up inspection. A rope access inspection photographs each defect and turns a general list into a measured scope. See building condition inspections.
- Group the work. Combine repairs, sealant and painting by elevation so the building is rigged once per drop.
- Tell residents. Windows closed and balconies clear on the days the crew is on their side. Our resident notice template can be copied.
- Ask for photo records. Before and after photos of each repair make it easier to sign off the work and plan the next cycle.
Frequently asked questions
Can concrete cancer be repaired by rope access?
Yes, most patch repairs to balcony slab edges, columns and façade panels can be carried out by rope access. The repair method should follow an engineer’s or remedial builder’s specification where the defect needs one.
Do residents need to leave the building during remedial works?
No. The work is done from outside. Residents are usually asked to keep windows closed and balconies clear on the days the crew is working on their side, and there can be noise during concrete repairs.
Is rope access cheaper than scaffolding for remedial works?
Often for repairs spread across a façade, because there is no scaffold to hire, erect and dismantle. For large continuous replacement work, scaffolding can be the better option. We compare the methods at inspection.
