The Major Problem With Weatherside Cladding17 Feb 2021

Over the year there have certainly been some problematic building materials used on New Zealand Homes. One of those being weatherside cladding.

During a House Inspection, our team of expert building inspectors look at a variety of exteriors where we assess your properties:

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

One common problem we spot is the use of weatherside cladding. An old exterior cladding product, which has only ever caused problems for homeowners.

What even is Weatherside Cladding?


Weatherside is an exterior house cladding and it was a very popular product in the early 1980s.

Weatherside is a hardboard that then had wood fibres glued together, however the glue failed and typically let moisture in.

What's the big issue with Weatherside Cladding?



The main issue is the way that the cladding is put together. It' allows moisture to get in, which then makes it prone to swelling and turning to mush.

After identifying the issues, the only way to fix the issue is to replace the cladding altogether. Because of this, it's important that you're aware of these potential renovation costs before you purchase your home.

How To Spot Weatherside Cladding



There's a couple of ways to spot whether a property was constructed with weatherside however, expert knowledge is required.

For example, an experienced eye will notice that Weatherside Cladding is slightly thicker than Hardiplank, the joiners are typically metal (not plastic) and typically the nails are flush with the surface, rather than protruding from the exterior of the board.

It's not easy to spot for the untrained eye, so always best to leave to the export building inspectors during your pre-purchase building inspection.
