Professional mould removal
Visible mould is only part of the problem. Our professional mould removal service deals with the contamination you can see, the spores you can't, and the conditions that allowed mould to grow in the first place.
Inspection & assessment
We assess the affected areas and the contributing factors, such as excess moisture, condensation, leaks or inadequate ventilation, so the treatment plan fits the real cause.
Containment & HEPA filtration
Where required, affected areas are prepared and contained. Professional HEPA vacuum filtration captures fine mould spores, dust and contaminated particles instead of spreading them around the property.
Professional mould removal
Visible contamination is removed and affected surfaces are professionally cleaned and treated using specialist mould-remediation products and equipment.
Our 10-Stage Mould Remediation Process
At Active Specialist Services, we use a comprehensive, multi-stage approach to mould remediation, combining professional assessment, specialist cleaning techniques and preventative recommendations to deliver effective, long-lasting results.
Our multi-stage treatment process includes:
- Technical & Moisture Survey - A detailed inspection of the affected areas, including moisture assessments to help identify the underlying causes of mould growth.
- Pre-Treatment Surface Testing - Protein swab testing to assess surface cleanliness and establish a baseline before treatment.
- Contamination Area Containment - Where required, affected areas are isolated using appropriate containment measures to help prevent the spread of mould spores and contaminated particles to unaffected areas during remediation.
- Air Filtration & Spore Control - Deployment of professional air scrubbers equipped with HEPA filtration to help capture airborne particles and mould spores during remediation.
- HEPA Vacuuming - Specialist vacuuming of affected surfaces to remove loose mould contamination and debris before treatment.
- Acti-Chem Surface Treatment - Application of our specialist Acti-Chem cleaning solution to suitable solid surfaces as part of the remediation process.
- ULV Fogging Treatment - Application of our specialist fogging solution using professional ultra-low-volume (ULV) equipment, where appropriate to the property and treatment requirements.
- Post-Treatment Surface Testing - Follow-up protein swab testing to assess surface cleanliness following treatment.
- Final Quality Assurance Inspection - A final inspection of the treated areas to review the completed remediation work and identify any outstanding concerns.
- Detailed Remediation Report & Recommendations - A comprehensive report documenting our findings, treatment procedures, moisture observations and recommendations to help minimise the risk of future mould growth.
Our 12-Month Conditional Guaranted
We offer a 12-month conditional guarantee on qualifying mould remediation treatments.
Our guarantee applies to the specific areas treated and is subject to the completion of any essential corrective measures identified during our inspection, together with ongoing adherence to relevant preventative recommendations.
Where underlying issues such as leaks, inadequate ventilation, insulation defects or excessive moisture remain unresolved, a guarantee cannot be issued until the necessary corrective measures have been completed and verified.
The guarantee period begins on the original treatment completion date, even where the certificate is issued later.
Our guarantee is provided in addition to your statutory consumer rights.
