Mould in Homes: The Hidden Health Hazard Most Homeowners Miss

Let’s be real—most of us don’t think twice about that patch of discolouration in the bathroom or a faint musty smell in the laundry. But those could be warning signs of a much bigger issue: mould infestation. And the longer it lingers, the worse it gets.

At Canberra Building Inspections & Reports, we’ve seen mould quietly destroy property value, compromise indoor air quality, and even lead to legal disputes between landlords and tenants. That’s why we always stress the importance of a professional mould inspection.

Why Mould Isn’t Just a Cosmetic Problem

Mould spores spread invisibly through the air, latch onto damp surfaces, and thrive in poorly ventilated areas. What starts as a small patch can quickly lead to:

  • Respiratory issues in children, the elderly, or anyone with asthma or allergies

  • Structural damage as mould feeds on timber, drywall, and insulation

  • Increased pest activity (cockroaches and mites love moist environments)

  • Rotting floorboards and ceilings

What Causes Mould? And Why It’s Often Hidden

Mould doesn’t show up overnight—it’s usually the result of ongoing issues like:

  • Water ingress from a leaking roof, cracked tiles, or unsealed windows

  • Poor plumbing or bathroom waterproofing

  • Inadequate ventilation in wet areas

  • Rising damp or condensation build-up

The worst part? You won’t always see it. Many cases we uncover are hidden behind walls or under flooring, only spotted during a full building inspection report.

How a Mould Report Protects You and Your Property

A professional mould report doesn’t just confirm visible patches. It assesses:

  • Current and potential mould hotspots

  • Indoor humidity levels

  • Water penetration or moisture problems

  • Health and safety risks

It’s especially critical if you’re:

  • Buying or selling a home

  • Managing a rental or strata property

  • Doing home renovations or extensions

  • Concerned about your family’s health

The Long-Term Costs of Ignoring Mould

Too many homeowners skip inspections and regret it later. Here’s what it can cost you:

  • Thousands in home repairs after structural damage sets in

  • Decreased property value during resale

  • Insurance complications if mould wasn’t disclosed or treated

  • Health issues that lead to long-term medical costs

Preventative action is always cheaper than remediation.

Simple Steps to Prevent Mould Growth

  • Use exhaust fans in kitchens and bathrooms

  • Regularly check for leaks in ceilings, roofs and plumbing

  • Keep indoor humidity under 60%

  • Seal external walls and windows properly

  • Book routine building inspections to catch issues early

Don’t Wait Until It’s Too Late
