FIXING WEATHERTIGHT FAILURES & LEAKY HOMES ACROSS THE GREATER WELLINGTON REGION 

Strait Construction in Porirua, NZ, specialises in diagnosing and repairing water ingress and moisture damage in buildings across the Wellington region, including Upper Hutt and Lower Hutt.

Leaky buildings are one of New Zealand's most significant construction challenges. Thousands of buildings constructed between the late 1980s and early 2000s were built using design methods and materials that failed to prevent water from penetrating the building envelope. Left untreated, water ingress causes progressive structural damage, timber rot, and mould growth that affects both the integrity of the building and the health of its occupants.

HOW LEAKY BUILDING REMEDIATION WORKS

Remediation begins with a thorough assessment of the building to identify where water is entering and how far the damage has spread. This process typically involves invasive investigation, removing cladding or linings in targeted areas to expose the structure beneath. The findings inform a remediation plan that addresses both the cause of the failure and the resulting damage.

Common causes of weathertight failure include inadequate flashings, missing or failed sealants, monolithic cladding systems without cavity drainage, decks and balconies that lack effective waterproofing, and penetrations around windows and doors that were not correctly detailed. We have extensive experience identifying each of these issues and developing lasting solutions.

THE REMEDIATION PROCESS

Once the scope of work is confirmed, remediation typically involves removing the failed cladding, replacing damaged structural timber, installing a new cavity-based cladding system with appropriate flashings and drainage, and completing all associated internal repairs. Our goal is to restore your building to a weathertight condition that meets current building code requirements and will perform reliably over the long term.

We work closely with building owners, body corporates, and project managers to keep the process as straightforward as possible. Clear communication, detailed documentation, and a focus on getting the work right the first time are central to how our team operates.

RESIDENTIAL & COMMERCIAL REMEDIATION

We have completed remediation projects on standalone homes, townhouses, apartment complexes, and commercial buildings throughout the Wellington region. Each project is managed by experienced professionals who understand the technical demands of remediation work and the importance of minimising disruption to occupants where possible.

With over 30 years in the construction industry and a proven track record in leaky building repairs, we bring the knowledge, qualifications, and practical experience needed to handle even the most complex remediation projects.

WHAT TO DO IF YOU SUSPECT A LEAKY BUILDING

If you notice signs of moisture damage in your building, it is important to act quickly. Delaying remediation allows water damage to spread further into the structure, increasing both the complexity and cost of repairs. An early assessment can help identify the extent of the problem and allow for a more targeted and cost-effective remediation approach.
