Living on the Gold Coast or in Northern NSW has so much going for it – the sunshine, ocean breezes, lush hinterland. But with all that humidity comes one unwanted guest: mould.
If you’ve noticed mould creeping across your ceiling, hiding behind furniture, or showing up in the bathroom, you’re not alone. Mould is incredibly common in our coastal and subtropical climate and as Gold Coast builders, we see a lot of it.
Mould can’t be ignored. It’s not just a cosmetic issue, mould can cause damage to the structure of your home and have serious implications for your health.
So, let’s talk about what causes mould, how to deal with it, and when it’s time to call in a professional like Preston Building for mould remediation.
Why mould shows up
Warm, humid weather and moisture provide the perfect environment for mould to grow. And on the Gold Coast and in Northern NSW, that’s pretty much a year-round reality. Whether it’s a leaky bathroom, poor ventilation, storm damage, or leftover water from past flooding, once moisture gets into your home, mould can settle in fast.
Some of the most common causes we see in homes around the region:
- Leaky plumbing or bathrooms
- Poor ventilation in older homes
- Damp air from air conditioning units
- Roof leaks after heavy rain
- Water damage that wasn’t dried out properly
Why it matters
Mould shouldn’t be ignored. It might start off small, but left untreated, it can spread into walls, ceilings, insulation and even floor cavities and the timber frame of your home.
Not only does it damage materials, but mould can also affect your health, especially if you have kids, elderly family members, or anyone with asthma or allergies. Common symptoms from mould exposure include:
- Persistent coughing or sneezing
- Skin and eye irritation
- Sinus congestion or headaches
- That constant musty smell you just can’t get rid of
If you’ve got mould in your home on the Gold Coast or Northern NSW, it’s important to act early.
Can you fix mould yourself?
Small spots of mould on bathroom tiles or windowsills? You might be able to get rid of it with regular cleaning and good ventilation.
But if the mould keeps coming back, or if it’s on ceilings, in walls, or spreading fast, it’s a sign there’s a deeper issue – it may be beneath your walls.
This is when proper remedial building experience is needed. That means identifying the source of moisture, removing any damaged materials, and treating affected areas to prevent it from returning.
