In London’s dense and varied housing stock, damp remains one of the most persistent and costly maintenance issues for flat owners and landlords. From Victorian conversions to modern apartment blocks, damp can silently undermine a property’s condition, reduce its value, and impact tenant health—leading to legal exposure and costly disputes. This guide explores the causes of damp in London flats, how professional damp proofing and ongoing maintenance protect your investment, and how Fraser Bond supports landlords with tailored property care solutions.
Condensation from poor ventilation, especially in kitchens and bathrooms
Penetrating damp from faulty brickwork, roofing, or external cladding
Rising damp due to a failed damp-proof course or inadequate ground drainage
Plumbing leaks from internal pipework or neighbouring flats
Given London’s varied architecture and high humidity, properties—especially older conversions—are particularly susceptible to damp-related issues.
Persistent damp can cause peeling paint, warped floors, mould growth, and structural deterioration—lowering your flat’s marketability and resale value.
Tenants exposed to damp and mould may develop respiratory issues. Under the Homes (Fitness for Human Habitation) Act 2018, landlords can be held liable for poor indoor air quality.
Local councils can serve improvement notices under the Housing Health and Safety Rating System (HHSRS) if damp is not addressed promptly, exposing landlords to fines or legal action.
Unresolved damp issues lead to tenant dissatisfaction, increased turnover, and damage to your reputation as a responsible landlord.
Ideal for ground-floor flats, this involves injecting chemical barriers into walls to block rising moisture.
Treating external walls and roofs to stop water ingress—particularly important in period buildings with porous brickwork.
Installing extractor fans, dehumidifiers, or passive vents to reduce condensation build-up.
Specialist plasters and damp-proof paints can contain minor damp problems and prevent mould recurrence.
Identifying potential damp sources early (e.g. leaky radiators, cracked seals) helps avoid expensive repairs later.
