Our Mould Remediation Services

Mould can be persistent, toxic, and difficult to detect – especially if it’s hidden behind walls, under flooring, or in ceilings. That’s why we go beyond surface-level cleaning to deliver comprehensive, professional mould cleaning services that last.

At O’Shea’s, we tailor each service based on the type and activity level of the mould. Whether it requires ozone treatment, biocides, or antimicrobials, our team is qualified to apply the safest and most effective method of removal. From one-room outbreaks to widespread infestations, we eliminate mould at the root and restore a healthy environment across all property types.

Air Sampling and Mould Identification

We use professional-grade air sampling techniques to detect hidden spores, identify the species, and assess activity levels to tailor an effective remediation plan for your space.

Mould Remediation Treatments

We deliver different remediation treatments for different situations, from high-strength ozone shock for airborne and widespread mould to biocides for deep-penetrating remediation and antimicrobial agents for long-term protection.

Mould Removal and Decontamination

Post-treatment, we will safely remove mould from all affected surfaces, cavities, and materials, then decontaminate the area to ensure any lingering spores are eradicated.

Content Assessment and Recommendations

We assess whether affected belongings can be safely restored or need to be responsibly disposed of, helping you make informed, cost-effective decisions about your property.

Post-Remediation Testing

We offer optional third-party testing to independently confirm that the environment is free of dangerous mould levels, granting you peace of mind in the safety of your surroundings.

Mould Prevention and Repainting Guidance

We also provide practical mould prevention advice, including ventilation improvements, moisture control, and mould-resistant paint application to keep spores from returning.

Who Needs Professional Mould Removal?

Our mould treatment services are ideal for:

How We Work

On-Site Inspection and Air Sampling

We begin with a detailed on-site assessment, checking for moisture sources, structural damage, and air quality. Air sampling is conducted if needed to determine the mould species and extent. This helps us recommend the right solution for your premises to achieve long-lasting results.

Remediation and Decontamination

Based on the findings, we apply the right combination of remediation methods – be it ozone shock treatment for rapid neutralisation, biocides for stubborn infestations, or antimicrobials for ongoing protection. All visible mould will be removed, and the area will be decontaminated to eliminate lingering spores.

Contents Assessment and Advice

Our mould removal staff will evaluate affected belongings and materials, advising whether they can be cleaned or should be discarded. This ensures the mould doesn’t return through contaminated soft furnishings or porous items.

Testing, Prevention, and Final Handover

We complete the process with a final sanitisation using hospital-grade, eco-friendly products and optional post-remediation third-party testing. You'll also receive advice on applying mould-resistant paint and preventing moisture build-up, helping you stay mould-free for good.

Great lads, great job.

FAQs

How do I know if I have a mould problem?

Mould often appears as black, green, or white patches on walls, ceilings, or tiles. Common signs include a musty smell, allergy-like symptoms, or visible water damage. If you’re unsure, O’Shea’s offers professional inspections and air sampling to confirm.

Is mould dangerous to my health?

Yes. Mould exposure can cause or worsen respiratory issues, allergies, and skin irritation, especially in children, the elderly, or those with compromised immune systems. Prompt removal is essential for maintaining a healthy indoor environment.

What causes mould to grow indoors?

Mould thrives in damp, humid environments. Common causes include poor ventilation, roof or plumbing leaks, rising damp, or condensation issues. Identifying and fixing the source is key to effective remediation.

How long does mould remediation take?

The timeframe varies depending on the extent of the infestation and the size of the affected area. Minor issues may be resolved in a few hours, while larger projects may take multiple days, including drying time and air testing.

Will the mould come back after treatment?

Not if the root cause – such as leaks or poor airflow – is addressed. We provide recommendations to prevent recurrence and can apply mould-resistant coatings in vulnerable areas for extra protection.

Do you use eco-friendly cleaning products?

Yes. Our team uses industry-approved, non-toxic and eco-safe products wherever possible, especially in homes with children, pets, or health-sensitive individuals. We can also provide safety data sheets upon request.

Do you offer third-party clearance testing?

Absolutely. We offer optional third-party air quality testing to verify that mould has been effectively removed. This is especially recommended for sensitive environments like medical clinics, aged care facilities, or rental handovers.

Do I need to vacate my property during the process?

In most cases, no. However, for severe infestations or ozone treatments, we may advise temporary evacuation of the affected area for safety. We’ll always inform you in advance.
