External Wall Remediation

Trident Facades provides external wall remediation services for residential, commercial and high-rise buildings where defects within an external wall system require investigation, repair, upgrading or replacement.

An external wall is made up of multiple components working together. Remediation therefore needs to consider the complete wall build-up rather than focusing solely on the visible façade finish.

What Is External Wall Remediation?

External wall remediation is the process of addressing defects or inadequate performance within an existing external wall system. Depending on the building, this can involve cladding, insulation, cavity barriers, fire stopping, membranes, support systems, fixings, render, substrate, windows, interfaces, and waterproofing. Ultimately, the appropriate remediation solution depends on the existing construction, the nature of the defects, and the requirements established through the relevant assessment and design process.

When Is External Wall Remediation Required?

Remediation may be required where an external wall has:

  • Fire safety concerns
  • Combustible materials
  • Defective cavity barriers
  • Missing or inadequate fire stopping
  • Deteriorated insulation
  • Water ingress
  • Defective cladding
  • Structural or fixing problems
  • Failed membranes
  • Poor thermal performance
  • Significant deterioration
  • Defective interfaces

Some projects require localised repairs, while others require extensive removal and replacement of the external wall system.

External Wall Remediation Process

  • Assessment

    1

    A thorough investigation of the existing timber cladding system to identify defects, moisture damage, rot, or compliance issues.

    Reviewing existing assessment information, conducting timber façade surveys, opening-up and intrusive investigations, and assessing timber species, battens, membranes, and fire stopping.

  • Strategy

    2

    Developing a tailored remediation plan based on the investigation findings.

    Determining whether the system can be repaired locally, requires targeted board or batten replacement, or needs full system removal based on the condition of the existing structure.

  • Design

    3

    Engineering the required remediation and specification for the building envelope.

    Developing a buildable specification covering timber selection, treatment standards, fire stopping, ventilation paths, interface detailing, and regulatory compliance.

  • Removal

    4

    Safely stripping away defective or non-compliant elements of the existing façade.

    Erecting secure containment, carefully removing degraded timber boards, battens, counter-battens, and fixings, and responsibly clearing away inadequate cavity barriers.

  • Repair

    5

    Repairing and upgrading the underlying structure, framing, and fire barriers.

    Correcting structural interfaces, installing proper mechanical fixings and support framing, and fitting certified cavity barriers and fire stopping at all critical junctions.

  • Replacement

    6

    Rebuilding the timber cladding system to modern performance and safety standards.

    Installing new breather membranes, insulation, ventilation cavities, and replacement timber cladding boards along with proper flashings and trim details.

    See our Timber Cladding Replacement service.

  • Completion

    7

    Final handover, quality verification, and project sign-off.

    Making good the work areas, conducting rigorous final inspections, and issuing the necessary completion documentation, safety certifications, and warranties.
