Finding mould behind a wardrobe, bookshelf or bed is unpleasant, but it's surprisingly common in Auckland homes. Because these areas receive very little airflow, they often become the perfect place for moisture to collect.
Cleaning the mould is only half the job. Preventing it from returning means dealing with the moisture that's causing it.
Why Furniture Makes It Worse
Large furniture placed hard against an outside wall restricts air movement.
The wall stays colder, humid air becomes trapped, and condensation can form where you can't easily see it.
Over time, mould begins to grow.
Other Contributing Factors
Mould is more likely if your home also has:
- Poor ventilation.
- High indoor humidity.
- Wet windows each morning.
- Inconsistent heating.
- Poor insulation.
Several small issues often combine to create the problem.
What Can You Do?
Helpful steps include:
- Leave a small gap behind large furniture.
- Heat the home consistently during winter.
- Reduce indoor moisture.
- Use extractor fans.
- Improve ventilation if condensation is persistent.
These changes help keep surfaces drier.
Clean Existing Mould Safely
Existing mould should be removed using appropriate cleaning methods before expecting ventilation or heating improvements to solve the issue.
If mould covers a large area or keeps returning, investigate the source of the moisture rather than repeatedly cleaning the surface.
