How are curtain wall maintenance findings prioritised?
Curtain wall maintenance findings are prioritised according to their risk to occupant safety, building security, weather resistance and the likelihood of further deterioration. Defects presenting an immediate or significant risk are addressed first, followed by issues that could affect performance or lead to more extensive repairs.
The findings are prioritised through a documented risk assessment that considers the condition of each defect, its location, the function of the curtain walling and the consequences of leaving it unresolved. This allows the most important work to be dealt with first while lower-risk items are planned in a controlled and proportionate way.
Immediate safety concerns take precedence. Any defect that could allow glass, framing, panels or associated components to become detached is treated as urgent. Loose or damaged glazing, failed fixings, distorted frames and signs of movement require particular attention, especially where they are above entrances, pavements, occupied areas or other locations where falling materials could cause injury.
The assessment also considers whether the defect affects the building’s ability to resist wind, rain or unauthorised access. Failed seals, open joints, damaged pressure plates and gaps around glazing can allow water penetration and may contribute to concealed deterioration. Damage affecting doors, ground-level glazing or other vulnerable points may also require early action where it compromises security.
Findings are generally considered under the following risk factors:
- Safety: the potential for injury, detachment or collapse of a component.
- Water resistance: the likelihood of leaks, dampness or damage to internal finishes and building fabric.
- Structural and functional condition: evidence of movement, corrosion, failed fixings, distortion or loss of support.
- Security: whether damaged glazing, frames or closures make the premises more vulnerable.
- Rate of deterioration: whether the defect is stable or likely to worsen quickly.
- Location and exposure: the position of the defect, its accessibility and the level of wind, weather or public exposure.
Defects with several contributing risks are normally brought forward in the maintenance plan. For example, a failed seal in an exposed upper-level elevation may be prioritised ahead of a similar seal in a sheltered area if the consequences of water ingress or further deterioration are greater. Equally, a cosmetic blemish may remain a lower priority where it has no effect on safety, weather performance or the operation of the building.
Findings are also assessed in relation to one another. A minor issue can become more important if it is part of a wider pattern, such as repeated water ingress, progressive corrosion or movement across adjoining bays. Addressing the underlying cause is often more effective than treating isolated symptoms, so the recommended sequence may include investigation before individual repairs are completed.
Where the inspection identifies a potentially hazardous condition, the area may need to be made safe before permanent remedial work is arranged. This can involve restricting access, removing a loose component where appropriate or introducing temporary protection. Such measures do not replace a proper repair; they control the immediate risk while the required solution is confirmed.
Once the higher-risk findings have been isolated, the remaining work can be grouped by access requirements, compatible materials and the extent of disruption involved. Combining related repairs may avoid repeated access arrangements and provide a more efficient maintenance programme, provided that doing so does not delay work that presents a significant risk.
The final priority should be supported by clear inspection records, photographs and a description of the recommended action. A useful report distinguishes between urgent remedial work, planned repairs and routine monitoring, rather than presenting every observation as equally serious. It should also identify any limitations on the inspection and note where further investigation is needed before a repair specification can be prepared.
GlassPlus UK can review curtain wall maintenance findings and advise on a practical order of works for commercial properties. Its recommendations are made with regard to safety, building performance and current building and safety regulations, helping property owners, facilities teams and managing agents move from inspection findings to an organised repair plan.
Priorities should be reviewed as the work progresses. A curtain wall condition can change after severe weather, accidental impact, a new report of water ingress or a change in how the building is being used. The maintenance record should therefore be updated when new information affects the original assessment.
Keeping the reason for each change alongside the inspection photographs and recommendations gives facilities teams a clear audit trail. It also helps contractors and property managers understand which actions remain outstanding and why the agreed sequence should be maintained or amended.
