Wall mould grows when moisture enters from leaks, condensation or rising damp and meets organic material on the surface. Treatment must remove the moisture source, dry the wall and treat the mould. Bleach and surface sprays do not reach mould within porous wall materials. Professional treatment dries, treats and removes contaminated material where required. Mould remediation reduces growth but cannot guarantee the space stays mould-free if the moisture source is not fixed.

Leaks, condensation, poor ventilation and rising damp. Mould needs moisture and organic material to grow on walls.
Surface mould can often be treated. Mould within plasterboard or behind walls usually requires removing and replacing affected material.
Black or green spotting, a musty smell, discolouration, or paint bubbling and peeling.
Bleach discolours mould but does not kill roots within porous materials and can damage surfaces. Professional treatment dries, treats and removes contaminated material.
Mould growth is reduced and the wall dried. We do not guarantee mould will not return if the moisture source is not repaired.
Identify and document the moisture source
Dry the wall and structure with professional equipment
Treat mould-affected surfaces with appropriate chemistry
Remove and replace contaminated plasterboard where required
Clean and treat the cavity
Verify moisture levels are safe
We provide this service across the Newcastle and Hunter region:
Surface mould can often be treated. Mould within plasterboard usually means removing and replacing the affected section.
If the moisture source is not fixed, mould can return. Drying and fixing the source are essential.
Mould can affect indoor air quality. Affected material should be treated or removed and the moisture source corrected.
Bleach discolours surface mould but does not kill roots within porous materials. Professional treatment is more effective.
Carpet Mould
Carpet mould grows when carpet, underlay or subfloor stays damp — after flooding, leaks, condensation or high humidity. Treatment must remove the moisture source, dry the affected layers and treat the mould. If mould has penetrated the underlay or subfloor, replacement is often safer than cleaning. Mould remediation reduces mould growth but cannot guarantee the space will remain mould-free if the moisture source is not fixed.
Read moreFlooded Carpet
Flooded carpet needs fast action. The first 24–48 hours decide whether the carpet and underlay can be saved and whether mould will develop. Professional response extracts the water, lifts the carpet to dry the underlay and subfloor, and uses drying equipment and moisture monitoring. If the water was contaminated (sewage or stormwater), replacement is often safer than cleaning. Call for emergency response immediately.
Read moreMusty Carpet Smell
A musty carpet smell usually means moisture and early mould growth in the carpet, underlay or subfloor. Fragrance only masks it. Professional treatment finds the moisture source, dries the affected layers and treats the odour compounds. If mould has colonised the underlay or subfloor, that layer usually needs replacing. Fixing the moisture source is essential — otherwise the smell will return.
Read moreSmoke Damage Cleaning
Smoke and soot damage continues after the fire is out — acidic soot etches surfaces and smoke odour penetrates porous materials including carpet, upholstery and walls. Professional smoke damage cleaning removes dry soot before it is driven deeper, then treats odour with appropriate methods. Some severely heat-damaged contents cannot be restored. An assessment determines what can be saved before work begins.
