Mould and Damp Report We have attended the property following the council notice to assess the ongoing issues of mould and damp. It is evident that attempts have previously been made to remediate the mould; however, these have not been carried out correctly and, more importantly, the root cause of the issue has not been addressed. As a result, the mould has returned and continues to affect multiple areas of the property. From our findings, the mould is widespread throughout the property, particularly around cold bridging areas such as external walls, ceilings, corners, window reveals, and high-level areas. There is also visible mould contamination in the bathroom and kitchen, including behind units and around fittings, indicating prolonged elevated moisture levels. The primary cause of this is a combination of penetrating damp from external defects, insufficient insulation, and excessive internal moisture due to leaks and inadequate ventilation/heating. In order to resolve the issue properly and prevent reoccurrence, the following works are required: External / Roofing Works (Priority) Scaffolding will be required to safely access the roof and carry out the necessary works. There are multiple defects contributing to water ingress, including: Perished mortar to ridge tiles Defective and aged lead work Broken and slipped slates/tiles Blocked and defective gutters and downpipes All gutters will require full clearance, with any damaged sections replaced as necessary. Downpipes must be unblocked and made fully operational. Ridge tiles will require repointing or renewal where mortar has failed. Lead work should be replaced to ensure watertight seals, and all broken slates/tiles must be replaced. If these external defects are not addressed, moisture will continue to penetrate the structure and the mould issue will not be resolved. This is the first and most critical stage of works. Thermal Insulation (Loft Areas) Due to the size of the property and the presence of multiple loft spaces (two to three separate areas), the current insulation is inadequate. All loft spaces should be upgraded to a minimum of 270mm insulation to meet current building regulations. Improving the insulation will significantly help with heat retention, reduce cold bridging, and limit condensation forming on ceilings and upper walls, which is a major contributing factor to mould growth. Internal Plumbing & Joinery Defects There are additional internal contributing factors increasing moisture levels within the property: Leaking kitchen sink tap Defective waste/trap under the sink Damaged and deteriorated kitchen cupboards These items will require repair or replacement to prevent further water ingress internally. Bathroom Defects The bathrooms show clear signs of mould and moisture retention, particularly to ceilings, walls, grout lines, and silicone joints. All grout and silicone will need to be raked out and replaced to provide a proper waterproof seal and prevent further moisture penetration. Heating & Ventilation The property currently cannot be maintained at a consistent temperature, which is contributing to condensation and mould growth. It is recommended that a qualified gas engineer attends to: Service and assess the boiler Ensure the heating system is fully operational Install or upgrade radiators where required to adequately heat the property We do not carry out gas works, so this would need to be arranged separately. Mould Remediation Works (After Repairs) Once all external and internal defects have been resolved, full mould remediation can be carried out. This will include: Down washing all affected areas with anti-fungal treatment Application of anti-mould solutions Repainting affected areas in anti-mould emulsion Due to the extent of contamination, this will likely involve the majority of the property (circa 95%) to bring mould levels back to a safe and acceptable standard. Final Making Good Previous repair attempts have not been completed to a satisfactory standard. Once all works above are completed, we can return to make good all affected areas and carry out finishing works to bring the property back up to the required standard in line with council expectations. Important Note Unless the external defects, insulation upgrades, internal leaks, and heating/ventilation issues are fully addressed, any attempt to remove mould will only be temporary and the problem will continue to return.
