Timber cladding replacement may be required where existing materials, support systems or detailing are no longer suitable for the building or cannot be effectively repaired.
Common issues include:
The appropriate replacement approach depends on the existing construction, condition, assessment findings and required performance.
Existing façade review – Reviewing available surveys, assessments, drawings and previous reports to establish the existing timber cladding system and known defects.
Façade investigation and opening-up – Investigating the timber cladding, support framing, ventilation arrangements, insulation and interfaces where further information is required.
Remediation strategy – Establishing the extent of replacement and the appropriate approach for the affected elevations.
Design and specification – Developing the replacement system, including timber species, treatment, support arrangements, ventilation, fixings, cavity barriers, fire stopping and interface details.
Timber cladding removal – Carefully removing existing timber boards and associated battens, fixings and defective support components.
Substrate and backing preparation – Inspecting and preparing the exposed construction, including repairs or replacement of defective components where required.
Ventilated cavity installation – Providing appropriate cavity and ventilation arrangements behind the replacement cladding.
Cavity barriers and fire stopping – Installing or reinstating required fire protection within the external wall system and around relevant interfaces.
Support systems and fixings – Installing new battens, rails, brackets or fixings as required by the replacement system.
Replacement timber cladding – Supplying and installing the specified timber cladding system, including associated trims and detailing.
Interfaces and weathering – Completing junctions around windows, doors, roofs, balconies and other façade interfaces to provide appropriate weathering and drainage.
Installation and completion – Completing the installation, making good, carrying out final inspections and addressing any identified snags.
The replacement system needs to work as part of the complete external wall rather than as a simple board replacement.
Considerations can include:
The replacement material and system may differ from the existing construction where this is appropriate to the building and remediation requirements.
Timber cladding replacement can be delivered as a standalone service or as part of a wider façade remediation project.
Where required, our dedicated survey team, Trident Facades Surveys, can undertake condition surveys and targeted opening-up to establish the existing construction before replacement works are developed.

We understand that façade and cladding remediation involves different operational and practical requirements depending on the property type.
Experienced in working on occupied multi-storey blocks where timber cladding requires repair, replacement or fire-safety improvement. We provide the technical scopes, material specifications and cost information needed by block managers, managing agents and surveyors, including for Section 20 consultations. Phased works and careful site management help minimise disruption to residents.
Supporting landlords, managing agents and facilities teams with the repair or replacement of degraded, weathered or non-compliant timber façades across commercial and mixed-use buildings. We plan works around active tenants, public access and business continuity, with replacement systems selected to meet the building’s performance, durability and fire-safety requirements.
Timber façade remediation requires careful consideration of fire performance, structural detailing, weather resistance and moisture management. Replacement systems may include A1 or A2-rated metal or fibre-cement panels designed to provide a timber appearance, or other suitable engineered systems. Works are delivered to the applicable design and building requirements, with relevant fire classifications and cavity barrier provisions incorporated where required. Completion documentation can include warranties, product information, photographic records and O&M documentation.
