Fixing Leaks – How We Work

When a leak has already started, quick patching is not enough. Our approach is designed to solve the problem at its root:

Inspection & Diagnosis – We carefully investigate to find where the water is entering.
Custom Repair Plan – Tailored solutions depending on building type and problem severity.
Waterproofing Application – Using membranes, sealants, or structural repairs to fully block water intrusion.
Final Protection – Ensuring the repair holds up under Christchurch’s unpredictable weather.

This process guarantees that the issue is fixed once and for all, not just covered temporarily.

Built for Canterbury Weather

Christchurch is famous for experiencing “four seasons in a single day.” Sudden downpours, wind, and strong sun can quickly test any structure. Our waterproofing repairs are specifically adapted to these conditions, ensuring they perform all year round.
