damp and mould

Case Study Overview: Long-Term Water Ingress from Roof and External Wall Defects Leaseholders living in converted buildings often assume that the freeholder or management company will promptly investigate reports of roof leaks and external structural defects. Unfortunately, that is not always the case. Where water ingress is allowed to continue for years, relatively minor defects can develop into persistent damp problems affecting multiple rooms within a property. MJV Solicitors acted for leaseholders of a top-floor maisonette who experienced longstanding dampness affecting the bedroom, living room and hallway. The evidence ultimately pointed towards rainwater penetration from defects associated with the flat roof and extensive cracking to external walls. After independent expert evidence supported the leaseholders’ case, the claim concluded with a negotiated settlement that included £9,2550 in compensation, repair works and payment of their reasonable legal costs.

Years of Damp Affected Several Areas of the Leasehold Property The leaseholders reported damp affecting several parts of their home over a prolonged period. The issues were concentrated around the upper parts of walls and ceilings within the bedroom, living room and hallway. The leaseholders believed the problem was being caused by water penetrating from the flat roof above the property. They also identified significant cracking to external walls adjacent to the roof area. According to the claim, the problems had been reported repeatedly over a number of years but remained unresolved. The claim alleged that defects to the roof and external structure were allowing moisture to enter the building envelope, resulting in recurring dampness internally. Landlord’s Surveyor Identified Potential Water Ingress from the Roof Following receipt of the Letter of Claim, the landlord instructed its own surveyor to inspect the property. The landlord’s surveyor reported that no active damp or mould was visible in the bedroom or living room at the time of inspection. However, the surveyor identified watermark staining to the hallway walls and ceiling above the landing and considered this indicative of potential water ingress. The report concluded that the most likely source was a defect associated with the flat roof above and recommended further investigation. External cracking to rendered walls was also identified and remedial works were recommended. The landlord’s surveyor estimated remedial works at approximately £2,750 plus VAT and recommended investigations to the roof together with repairs to the external rendered wall system. Independent Expert Found Rainwater Penetration and External Wall Defects An independent expert surveyor was later instructed on behalf of the leaseholders. Unlike the landlord’s inspection, the expert identified evidence of rainwater penetration affecting the bedroom, living room and hallway. Water staining, flaking decoration, cracking and damage to internal finishes were recorded. The expert also identified extensive cracking to external walls and concluded that rainwater was penetrating through defective roof waterproofing and external wall defects. The expert considered that the dampness observed within all three locations stemmed from the same underlying causes. The report recommended investigation and repair of the flat roof together with investigation and repair of the external wall cracking, followed by internal reinstatement works. Photographs accompanying the report showed cracking to the external walls, staining to internal ceilings and walls, and evidence of water ingress affecting several areas of the property. Landlord Disputed Liability for the Damp and Water Ingress The landlord denied liability for the bedroom and living room allegations and maintained that no evidence of damp had been identified during its own inspection. In relation to the hallway, the landlord contended that it had not received sufficient notice of the defect but nevertheless agreed to investigate further and indicated a willingness to undertake external works on a goodwill basis. The dispute therefore centred on the extent of the damp, the significance of the external defects and whether the landlord’s repairing obligations under the lease had been breached. How the Expert Evidence Supported the Leaseholders’ Claim A significant feature of the claim was the consistency between the leaseholders' allegations and the independent expert evidence. The expert concluded that the primary causes of the internal dampness were rainwater penetration through defective flat roof waterproofing and substantial cracking to external walls. The report recommended urgent remedial works and valued the required repairs at approximately £7,165 including VAT. The expert considered that prompt intervention was necessary to prevent continuing deterioration and further damage to the property. The Outcome for Our Clients: £9,250 Compensation and Repair Works Agreed Following the exchange of expert evidence and negotiations between the parties, a settlement was reached before trial. The settlement included: • £9,250 in damages • completion of the works identified within the landlord surveyor’s report. • payment of the claimants’ reasonable legal costs. The offer was subsequently accepted on behalf of the leaseholders, bringing the claim to a conclusion without the need for a contested court hearing. Why This Leasehold Disrepair Case Matters This case demonstrates that persistent damp affecting leasehold properties can often originate from defects to roofs and external structural elements rather than internal lifestyle factors. It also highlights the importance of obtaining independent expert evidence where liability is disputed. In this matter, the independent expert identified widespread evidence of rainwater penetration and external structural cracking that supported the leaseholders' case and provided a clear explanation for the ongoing damp issues. The successful settlement allowed the leaseholders to recover compensation while also securing remedial works designed to address the underlying causes of the water ingress.
