Don’t risk buying a leaky home! Get a professional weathertightness report to ensure your property is safe and dry.

Why Weathertightness Inspections Are Important in New Zealand

Thousands of New Zealand homes constructed between 1990 and 2004 have weathertightness issues, earning them the nickname of “leaky homes”. These issues are the result of poor design, materials, and construction methods, which allow moisture to penetrate the walls of a building.

If left undetected, this trapped moisture can impact the structural stability of a house and lead to serious health risks for its occupants. Unfortunately, even severe leaks often go unnoticed until the building materials begin to fail.

That’s why it’s a good idea to get a weathertightness inspection if you’re looking to purchase a house that was constructed in this era or if you have reason to suspect any weathertightness issues.

Our licensed and fully qualified building surveyor can assess your property for signs and risks of moisture ingress and provide you with a detailed weathertightness report. This will give you a better understanding of the condition and potential issues of a property and outline any preventative measures for you to take.

Our Weathertightness Inspection Process

Here’s what you can expect from our weathertightness inspections.

When carrying out a leaky home inspection, we don’t just rely on a single assessment method or diagnostic tool. Instead, we view the house as a whole and consider various risk factors.

This involves examining the plans of the house, followed by a comprehensive visual inspection of the exterior and interior elements and non-invasive moisture detection testing.

If this approach throws up any red flags, we can conduct in-depth surface moisture testing, along with dye testing, exploratory invasive investigations, and timber sampling to determine the degree and type of decay.

We then present our findings in a written weathertightness report that highlights any areas of concern and possible remediation measures.

Inspection of the plans and materials

We will begin by inspecting the plans of the house to determine the era, how it was constructed, and which products were used to assess the level of design risk.

Visual inspection of the property

Next, we will carry out extensive on-site testing using various tools and tests. This allows us to pinpoint if, where, and how leaks are occuring.

Written weathertightness report

After we have completed our assessments, we will write up a weathertightness report highlighting any concerns and necessary measures.
