Protecting Buildings. Restoring Performance.
The façade is your building’s first line of defence against weather, moisture and environmental exposure. When it begins to fail, the consequences often extend far beyond cosmetic damage.
Cracked render, failed sealants, spalling concrete, deteriorating brickwork and water ingress are all signs that the building envelope may no longer be performing as intended
At Metro Remedial, we specialise in façade repairs and building envelope remediation for strata, commercial, government and education buildings across Sydney. Working from engineer and Design Practitioner documentation, we deliver technically sound repairs that restore the integrity, appearance and long-term performance of your building.
Render Repair and Reinstatement
Cracked, hollow, or delaminating render is one of the most common facade defects in Sydney’s strata buildings. We remove deteriorated render back to sound substrate, address the underlying cause as specified, and reinstate an appropriate render system matched to the building’s environment and original specification.
Sealant Joint Replacement
Failed or deteriorating sealant joints are one of the primary water entry points in multi-storey facades. We remove failed sealant, prepare the substrate correctly, and install appropriate replacement sealant systems.
Facade Waterproofing
Where the underlying waterproofing system has failed or was never adequate, we carry out full or targeted facade waterproofing to re-establish the building envelope. This work is integrated with our broader structural remediation where concrete cancer or water ingress has reached the structure below.
Interim Facade Solutions
Where full facade rectification isn’t immediately achievable within current levy funding, we can deliver an interim solution that stops active water ingress and protects the building envelope while the budget for full works is secured. We’ll always be clear about what the interim fix covers and what the permanent works look like.

Common Façade Problems
Many façade defects begin as relatively minor issues before developing into significant structural or waterproofing problems.
Common defects include:
- Cracked render
- Rust staining
- Concrete spalling
- Loose or drummy render
- Failed movement joints
- Deteriorated sealants
- Water ingress through external walls
- Cracked brickwork
- Efflorescence
- Loose masonry
- Corroded reinforcement
- Paint system failure
Early intervention can significantly reduce repair costs and prevent further deterioration.
Our Facade Repair Process
01 Assess the Building
Every project begins with understanding the defect. We inspect the building, review any available reports or documentation, and identify the likely cause of the deterioration.
Where an engineer’s or Design Practitioner’s report has already been prepared, we review the repair methodology to ensure the works are delivered as intended. If further investigation or engineering input is required, we can work with your consultant or recommend the appropriate specialist.
02 Plan the Works
Every building is different. We develop a construction methodology that considers safe access, occupied buildings, weather exposure and staging requirements.
03 Complete the Repairs
Our experienced remedial team undertakes repairs in accordance with the approved design, restoring the building envelope using proven remedial construction techniques.
04 Protect the Building
Where required, waterproofing systems, protective coatings and movement joints are reinstated to improve durability and reduce future maintenance.
05 Quality Assurance & Handover
Completed works are inspected, documented and handed over in accordance with project requirements.
Why Façades Fail
Façade deterioration is rarely caused by a single issue.
Common contributing factors include:
- Building movement
- Thermal expansion and contraction
- Water ingress
- Failed waterproofing
- Deteriorated sealants
- Corrosion of reinforcement
- Carbonation
- Chloride attack
- Ageing construction materials
- Inadequate maintenance
Understanding the underlying cause is essential to delivering a durable repair.

Frequently Asked Questions
What is façade remediation?
Façade remediation is the repair and restoration of a building's external envelope. It may include repairing concrete, render, brickwork, sealants, movement joints, waterproofing systems and protective coatings to restore structural integrity and weather resistance.
What causes façade deterioration?
The most common causes include water ingress, building movement, ageing materials, corrosion of reinforcement, thermal movement, failed sealants and inadequate maintenance.
Can water enter through façade cracks?
Yes. Even small cracks can allow water to penetrate behind the façade, leading to internal leaks, corrosion of reinforcement, mould growth and further deterioration if left untreated.
Can façade repairs be staged?
Yes. Many projects can be completed in stages, allowing Owners Corporations to prioritise critical defects while planning future repair programs around available budgets.
Do residents need to move out?
In most cases, no. We regularly undertake façade remediation in occupied apartment buildings and commercial properties while maintaining safe access and clear communication throughout the project.
Do you work from engineers' reports?
Yes. We regularly deliver façade remediation projects in accordance with engineer and Design Practitioner documentation and work closely with consultants throughout the construction process.
