Leak sources are difficult to identify from inside the building
Rope Access and Façade Leakage Repair
ISS coordinates rope-access inspection and repair for façade joints, windows, external walls and difficult-to-reach building areas where water ingress affects occupied spaces.

Control the risks before they become delays, defects or downtime.
ISS starts by understanding the operational requirement, physical site conditions, technical interfaces and expected handover outcome.
Conventional access equipment cannot reach the repair location efficiently
Repairs fail when surface preparation, sealant compatibility or testing is inadequate
A coordinated scope from survey to close-out.
The exact solution is confirmed after a site assessment and review of client, landlord and authority requirements.

Compliance responsibilities are defined before work starts.
Work at height requires risk assessment, competent personnel, suitable equipment, supervision and an emergency or rescue plan. Site-specific controls and permits are established before work begins.

Façade water-ingress rectification
For a Singapore logistics facility, ISS’s repair approach combined internal leak mapping, external rope-access inspection, joint preparation, sealant replacement and photographic close-out across identified façade zones.
- Targeted repairs based on observed leak paths
- Access method planned around live operations
- Documented repair locations and completion status
Important questions before requesting a quotation.
How do you locate the source of a façade leak?+
We review internal signs, weather direction, joint condition, window perimeters and external defects. Water testing may be used where suitable and approved.
Is rope access safer than scaffolding?+
Safety depends on the site, work scope and controls. Rope access can reduce ground obstruction and reach difficult areas, but it requires competent personnel, equipment checks and rescue planning.
Can repairs be performed during building operations?+
Often yes, with controlled exclusion zones, weather monitoring, access coordination and communication with building occupants.
Do you provide photographs and reports?+
Yes. The agreed scope can include defect mapping, before-and-after photographs, repair records and close-out observations.

Tell ISS what you need, where the site is and your preferred timeline.
Director Michael will review the requirement and advise the next practical step for survey, quotation or technical discussion.
