Commercial Mould Removal & Wall Replastering

Rely on us for commercial mould removal and wall replastering in Australia.


Mould is a fungus that can naturally grow in various environments. When your office basement or shop’s exterior and interior surfaces become damp, it creates conditions that allow mould to thrive. This results in airborne spores developing into colonies and forming large patches—which is never good news for a business. 

Mathiou Services is here to help resolve the issue before it gets out of hand. Our team provides comprehensive commercial mould removal and wall replastering services in Australia. Contact us the moment you suspect mould in your commercial building. You can identify mould by its appearance—it can look like black spots or blue, green, white or red stains on different surfaces. Another telltale sign of mould issue in your space is the presence of distinct discolouration on walls and ceilings.

Commercial mould removal


Mould forms on walls when the conditions are right for its growth. Mould spores can settle on surfaces such as walls, especially in moist and poorly ventilated areas.

When these spores find a suitable environment with enough moisture, they begin to grow and spread, forming colonies. This can happen on any surface, but porous materials such as drywall & wallpaper are particularly susceptible to mould growth.

Remember that water damage can cause mould issues. Leaks from plumbing or flood damage allow moisture to accumulate on walls. Humidity levels in a room can also contribute to mould problems, especially in areas like bathrooms and kitchens where steam and moisture are produced regularly.


The signs of mould growth in commercial spaces are similar to those in residential buildings. Some common signs include:

  • Visible & existing mould: Mould can appear as fuzzy or slimy patches on walls, ceilings, floors & other surfaces. It can be black, green, white or yellow.

  • Musty odour: Mould often emits a musty smell. So if you notice a persistent musty odour in your business space, it could indicate mould issues.

  • Discolouration: In early stages, mould can cause stains or discolouration on walls, ceilings and other surfaces. It can appear as dark spots or patches.

  • Health symptoms: Mould exposure can cause various health symptoms, such as coughing, sneezing, wheezing, headaches and eye irritation. So watch out for employees or customers experiencing these health symptoms.

If you suspect mould problems in your commercial space, take immediate action. That way, you can identify and address the issue to protect the health and safety of employees and customers. A professional mould remediation company like us can perform an assessment and develop a plan to remove the mould from walls safely. 



Replastering is often necessary to address the root cause of mould issues and prevent it from returning. Mould thrives in damp environments, so if there is mould on the surface of a wall, it is likely there is excess moisture trapped within the wall itself.

Replastering the wall can help address the issue by removing the affected plaster, which may be holding onto moisture and mould spores, and replacing it with new, dry plaster. It prevents the mould from spreading further and can improve the overall air quality in the room.

Additionally, replastering can help create a smooth and even surface, which can be particularly important if the previous plaster has been damaged by mould or attempts to clean it.

When you hire us, we will do all that on top of commercial mould removal. It’s our duty to restore the safety of your shop, child care centre or office. We’ll also likely perform a water damage inspection to see if existing leaks are the culprit.

We have recently had our children’s/staff bathroom renovated by your company and I just wanted to write to you to say what a fantastic job they did, we are so impressed with how much work they achieved in such a short space of time.

Employees are always polite and incredibly helpful when they are on site.



An amazing result, the bathroom looks completely transformed from what it was. The children are excited and are being more respectful of their own environment as they practice health and hygiene. The boys were happy to assist in touching up any areas of painting.



  • How to remove mould from walls permanently?

The best way to permanently remove mould from painted walls is to identify and fix the underlying moisture problem first, then use trusted commercial mould removal products to clean the affected area. Ensure the area is well-ventilated, wear protective gear and use a stiff-bristled brush to scrub the mould away. Want to prevent mould from returning? You may also need wall replastering. But it’s best to let a commercial mould remover like us do all the work to ensure the removal is safe and effective.

  • Why do you need to replaster mouldy walls?

Replastering mouldy walls may be necessary if the mould has penetrated deep into the plaster and cannot be removed completely. Mould can also weaken the structural integrity of the plaster and compromise its ability to provide a smooth and even finish. Replastering ensures complete mould removal and a fresh, mould-resistant layer that can keep the issue from recurring.

  • How long does the commercial wall mould removal & wall replastering take?

The time it takes for commercial mould removal & wall plastering varies depending on the extent of the damage and the size of the affected area. It can take anywhere from a few days to several weeks to complete, depending on factors such as the severity of the mould, the amount of replastering required, and the drying time of the new plaster. Contact us today; our team of mould removal specialists will assess the situation and provide an estimated timeline for the project.

  • How does flood damage cause mould on walls?

Flood damage can cause mould on walls by creating a moist environment where it thrives. Water can seep into walls and remain trapped, allowing mould spores to grow and spread quickly. No proper flood cleanup and drying can cause the mould to continue to spread, leading to further damage and potential health hazards. Flood damage also often carries contaminants and bacteria that can contribute to mould issues.
