Mould -Like Substance & Mildew Removal Description

Dark spots or mildew on walls, ceilings, or caulking can be more than just unpleasant—they often signal trapped moisture or poor ventilation. At CNG Contracting, we safely handle Mould & Mildew Removal, treating visible growth with care and precision to restore a clean surface.

Our process begins with identifying affected areas and understanding the root cause, such as humidity leaks. We use approved cleaning agents and surface-safe techniques to eliminate buildup, remove staining, and discourage regrowth, protecting your finishes and reducing odors. During service, we contain the workspace and ensure proper ventilation. Once finished, surfaces are left clean, dry, and safe. Practical, thorough, and handled with care from start to finish.

Frequently Asked Questions

Will the mold come back?

Cleaning removes the growth, but unless the source of moisture (like poor ventilation or a leak) is fixed, it may return. We help identify the cause so you can solve the problem permanently.

Can you remove mold from silicone caulking?

If mold has grown inside the silicone sealant, it cannot be cleaned out. In these cases, we must cut out the old caulking, sanitize the area, and apply fresh, mold-resistant silicone.

Is the cleaning solution safe?

Yes. We use professional-grade antimicrobial solutions that are effective against biological growth but safe for your home's surfaces when applied by our trained team.

Area to Cover

Why is a Technical Visit necessary?

Bleach does not kill mold roots on porous surfaces like drywall; it only bleaches the color, allowing the mold to return stronger. Furthermore, painting over mold without proper remediation seals the moisture in, causing the paint to bubble and peel. Our Mould & Mildew Removal assessment identifies if the issue is merely surface-level (condensation) or if there is an active leak behind the wall that requires a more structural approach before cleaning begins.
