The Major Problem With Weatherside Cladding17 Feb 2021

Over the years, there have certainly been some problematic building materials used on New Zealand Homes. One of these is weatherside cladding. During a House Inspection, our team of expert building inspectors look very closely at the exterior of the property. We assess a range of aspects, including:

- Material Used
- Condition
- Exterior Joinery
- Flashings
- Glazing/Seals
- Stairs/Patios
- Plumbing
- Gullies/Vents

While carrying out this exterior inspection, the use of weatherside cladding is a big problem we often spot.

What Is Weatherside Cladding?


Weatherside is an old exterior cladding product, which unfortunately has only ever caused problems for homeowners. While it was a very popular product in the early 1980s, it has not stood the test of time. Weatherside is essentially a hardboard with wood fibres glued together. However, this glue typically fails and lets moisture in over time.

What's the Big Issue with Weatherside Cladding?


The main issue is the way that the cladding is put together. Because it allows moisture to get in relatively easily, it is prone to swelling and turning to mush. Furthermore, once this issue is identified, the only way to fix it is actually to replace the cladding altogether. Because of this, it's important to be aware of these potential renovation costs before you purchase a home.

How To Spot Weatherside Cladding


There are a couple of ways to spot whether a property was constructed with weatherside cladding. However, expert knowledge is required to identify them. For example, an experienced eye will notice that weatherside cladding is slightly thicker than HardiePlank. Furthermore, the joiners are typically metal rather than plastic. The nails are also likely to be flush with the surface, rather than protruding from the exterior of the board.

So, while it is possible to tell the difference, the signs are not easy to spot for the untrained eye. That’s why it’s always best to arrange a pre-purchase building inspection and leave it to the experts.
