Specialist in leaky building remediation & pioneering industrial abseiling in New Zealand since 2002.

At Zenith, we deliver expert building remediation services with one key difference — we are able to perfom manu remediation needs by rope access. As one of New Zealand’s leading industrial abseiling contractors, we specialise in repairing, resealing, and restoring defective building envelopes without the need for costly and disruptive scaffolding.

Whether you’re dealing with a leaky building, façade failure, or ageing waterproofing, Zenith offers a smarter way forward — especially for multi-storey residential and commercial buildings where access is difficult and budgets are tight.

Leaky Building Specialists — At Height

The leaky building crisis has impacted thousands of buildings across New Zealand. Zenith offers a unique remediation capability for these structures — combining diagnostic expertise, durable repair systems, and safe rope access techniques that avoid the visual and financial impact of full scaffolding.

We focus on targeted repairs that stop water at its entry point: failed sealant joints, cladding junctions, cracked façades, internal gutters, and joinery interfaces. Our team works from height using industrial abseiling and engineered safety systems, allowing us to complete repairs faster, safer, and more economically.
