FAQs
Damp Survey FAQs for London Properties
Find answers to common questions about damp surveys, rising damp, condensation, and Awaab's Law compliance.
Common signs include damp patches on walls up to 1 meter high, tide marks or salt deposits, peeling wallpaper, damaged plaster, rotting skirting boards, and a musty smell. Rising damp is particularly common in Victorian and Edwardian properties throughout London with aging or failed damp proof courses (DPCs). We recommend booking a professional damp survey to confirm the diagnosis and identify the most appropriate treatment for your specific property.
Rising damp occurs when groundwater moves up through walls by capillary action, typically affecting ground floor walls up to 1 meter high—a common issue in older London properties. Condensation occurs when warm, moisture-laden air contacts cold surfaces, typically worse in winter and in high-humidity rooms. The treatments differ significantly, making accurate diagnosis essential.
Damp surveys in London start from £300 inc VAT, with pricing based on property size. All surveys are fixed-price with no hidden costs. Your quote will reflect the size, access, and scope required to deliver a robust, independent report.

Awaab's Law (October 2024) requires social housing landlords to investigate damp and mould within 14 days of a tenant report and complete repairs within strict timeframes. It's expected to extend to private landlords soon. Our professional damp surveys help landlords comply with these legal requirements and protect their tenants' health.
We offer same-day and next-day appointments across London and Greater London, depending on availability. Reports are typically delivered within 2-3 working days, making our service ideal for property transactions with tight timelines or landlords needing to comply with Awaab's Law requirements.
Why are Victorian and Edwardian London properties prone to rising damp?
Most Victorian and Edwardian properties built in London (1850s-1910s) were constructed with solid walls and no damp proof course (DPC), or with outdated slate DPCs that have failed over time. Rising damp is endemic to these period properties, especially in areas like Kensington, Camden, Islington, and across central London.
What areas of London do you cover?
We provide professional damp surveys across all of Greater London, including central London boroughs (Westminster, Kensington & Chelsea, Hammersmith & Fulham), North London (Islington, Camden, Haringey), South London (Wandsworth, Battersea, Clapham), East London (Tower Hamlets, Hackney, Newham), West London (Ealing, Richmond), and outer London areas.
What treatment options are available for rising damp?
Treatment options depend on the severity and cause. Options include installing a new chemical damp proof course (DPC), electro-osmotic systems, cavity injection, improved ventilation, and remedial plastering. For Victorian and Edwardian London properties, we often recommend sympathetic treatments that respect the building's historic fabric.
