Mould and mildew are more than just unsightly — they’re damaging, dangerous, and downright persistent. These unwanted guests thrive on external surfaces exposed to moisture, turning clean facades, driveways, and walls into patchy, discoloured hazards.
In Western Australia’s varied climate — from humid coastal suburbs to dry inland areas — keeping your home or business mould-free is essential for safety, presentation, and long-term property protection.
Here’s why removing exterior mould and mildew should be part of your regular maintenance routine — and how professional cleaning services make a real difference.
1. Restore and Protect Your Kerb Appeal
First impressions matter. A home or storefront covered in green or black mould stains sends the wrong message — no matter how clean the inside is. Whether you’re welcoming guests, customers, or clients, a spotless exterior enhances the visual appeal and professionalism of your property.

2. Prevent Structural Deterioration
Left untreated, mould and mildew slowly eat away at your surfaces. Over time, this can lead to rot, surface erosion, and costly repairs. Whether it’s timber, concrete, brick, or render, keeping surfaces clean helps protect the materials underneath — and keeps your property solid from the outside in.
3. Improve Health and Air Quality
Mould spores don’t just stay outside — they can enter your home or business through windows, doors, and ventilation. For those with allergies or respiratory issues, this can become a serious concern. Exterior mould removal helps minimise the risk of spore transfer indoors.
4. Reduce Slip Hazards
Mildew and algae create slick surfaces — especially on shaded concrete paths, timber decks, or tiled walkways. These surfaces become serious slip hazards when wet. Regular mould treatment helps prevent accidents, especially in high-traffic zones like business entrances, schools, or family homes.
5. Extend the Life of Your Surfaces
Routine cleaning not only restores appearance — it also extends the lifespan of external materials. Avoid premature deterioration of walls, paths, and fences by keeping them mould-free, sealed, and protected all year round.
6. Environmentally Safe Cleaning Practices
We use biodegradable, eco-friendly mould removal treatments that are safe for use around pets, plants, and kids. Our products are tough on mould, but gentle on the environment — a must for environmentally aware homeowners and commercial sites in WA.
FAQ: Mould & Mildew Removal
Can I clean mould off myself with bleach?
Bleach may whiten the surface, but it often doesn’t kill the root structure. That’s why mould comes back quickly. We use professional-grade solutions that kill spores at the source and slow regrowth.
How often should I clean the exterior of my property?
For most homes and commercial buildings, an annual soft wash or pressure cleaning is ideal. In shaded or high-moisture areas, we may recommend a bi-annual treatment.
Is pressure washing safe for all surfaces?
We assess every surface before cleaning and use low-pressure soft wash techniques where needed to protect your paint, render, or timber.
