Owning a leaky home in New Zealand is not just a headache—it's a serious concern with health, financial, and structural implications. Leaky homes were primarily built between the late 1980s and mid-2000s, often using cladding systems that lacked proper drainage. When moisture gets trapped between the cladding and the inner walls, it creates an environment ripe for mould, rot, and other damages that aren't always immediately visible. Cowan Building takes an in-depth look at leaky homes in New Zealand and what homeowners need to know to ensure their investment is safe.
Why Should I Be Worried About A Leaky Home?
A leaky home can affect both your property value and your health. If left unchecked, moisture build-up can lead to dangerous mould growth, which has been linked to respiratory issues and other health concerns. Structurally, persistent water intrusion can cause the timber framing to rot, compromising the home's integrity and leading to potentially costly repairs. Financially, the costs of repairs, combined with potential legal fees, can be enormous, and ignoring the issue only makes things worse. This underscores the urgent need to address any potential leaky home issues.
How Do I Moisture Test For A Leaky Home?
If you're worried about moisture, there are a few ways to check your home. You can purchase a basic moisture meter from hardware stores, which gives you a reading of moisture levels in walls and ceilings. However, this might not be enough. I recommend getting a professional weather tightness inspection to identify any hidden moisture issues that could escalate into serious problems.
What Are The Dangers of a Leaky Home?
The most significant danger of a leaky home lies in undetected damage. The moisture trapped behind the walls can lead to toxic mould growth, which can affect your health, especially if you suffer from asthma or allergies. From a structural perspective, water exposure weakens materials, causing rot and corrosion. Over time, this can turn small leaks into significant structural damage, which might lead to a total re-cladding of the home—an extremely expensive process.
The Problem in New Zealand: A Historical Issue
New Zealand's leaky home crisis stems from poor building practices, inadequate materials, and flawed regulations. Homes built in the 1990s and early 2000s with cladding were susceptible to moisture problems exacerbated by New Zealand's wet climate. This led to widespread issues, with thousands of homes nationwide affected by what's now known as the "leaky building syndrome".
Why Should I Call in a Professional If I'm Worried About A Leaky Home?
If you suspect your home may have a weather tightness issue, it's essential to call in professionals. A certified building inspector or weather tightness expert, with their specialised tools and knowledge, can perform thorough checks to assess the extent of the damage. Attempting DIY fixes can often make matters worse, leading to even more costly repairs down the line. An expert can also guide you through the repair process and ensure all work complies with New Zealand's building standards, providing you with the reassurance that your home is in good hands.
Regulations and Laws Around Leaky Homes
New Zealand has introduced regulations to address the leaky home crisis, including the Weathertight Homes Resolution Services Act. This law allows homeowners to seek assistance from the government if their home meets certain damage criteria. Under this act, homeowners can apply for financial assistance to repair their leaky homes. Additionally, builders now face stricter standards under the updated Building Code, which mandates better weather tightness measures. It's also worth noting that sellers must disclose weather tightness issues, and buyers should perform due diligence when purchasing a property built during a risky period.

What Are The Signs of a Leaky Home I Need To Know?
Common signs of a leaky home include:
Stained ceilings and walls: Discolouration can indicate moisture seepage.
Sagging roof or wall linings: This may result from trapped water, causing the materials to soften and warp.
Mould growth: Visible mould, particularly around windows and corners, is a clear indicator.
Musty odours: A persistent damp smell can suggest hidden water damage.
Bubbling or peeling paint: When water gets trapped, it pushes through the paint, causing bubbles or peeling.
