Ace Abseiling replaces failed window and joint sealant on strata and commercial buildings across Sydney by rope access. Old sealant is cut out, the joint is cleaned and prepared, and a new sealant suited to the joint movement and exposure is applied, so water stays out before it becomes a leak.
Our leak detection process is thorough and reliable.
Furthermore, we address every issue carefully — from window seals to structural joints, so your property stays protected long after the job is done.
Identifying the source of a leak can be challenging. However, our specialists find problems quickly and effectively. We perform water testing at the correct pressure to simulate heavy storms, so we can trace building leaks from wind-driven rain that a visual check would miss. Here is what happens in a façade water test.
From small water ingress to major seal failures, we handle each issue with precision and care.
Whether you need window sealant replacement, a joint repaired or cracks in walls fixed, we have the right solution. Our caulking and sealing services use premium materials that deliver durability and long-lasting results.
Sealant replacement is one of the most common remedial jobs on Sydney apartment and office buildings, because exterior sealant ages faster than the materials either side of it. It is often done in the same rope access setup as building remedial works and façade repairs or a repaint, which saves a second mobilisation. The strata building maintenance calendar shows how sealant inspections fit with anchors, window cleaning and painting.
Sealant that has hardened, cracked, shrunk away from one side of the joint or gone chalky has stopped moving with the building. Read more in signs your window sealant needs replacing. If water is already getting in, start with high-rise leak detection so the repair targets the real entry point.
Every project is different. That’s why we adjust our approach based on your specific needs. Our techniques range from soft pressure testing to replicating real-world weather conditions, so leaks are traced to their real source.

Polyurethane and silicone-based sealants are common choices, selected based on joint movement, exposure, and the surrounding material. Ace Abseiling chooses the appropriate sealant type for each project across Sydney, matching product flexibility and UV resistance to the specific building conditions to maximise how long the seal lasts.
Absolutely. Preventative maintenance catches shrinking or cracking sealant before water actually gets through. Ace Abseiling offers scheduled sealant inspections for buildings across Sydney, replacing joints proactively so owners avoid the disruption and expense of chasing an active leak once internal damage has already occurred.
Ace Abseiling specialises in tracing and fixing persistent water leaks on high-rise buildings across Sydney, using rope access to inspect and reseal problem areas directly on the facade. Rather than guessing at the source, technicians get right up to the joint, window, or crack causing the ongoing issue.
Technicians trace ingress points by inspecting sealant joints, window frames, and render cracks up close while suspended on ropes. Ace Abseiling investigates water leak sealing issues this way across Sydney, often finding that damage appearing inside a unit actually originates several floors higher on the facade.
