Leak to dry to treated, one company in Mayfair
Mayfair's housing runs from grand stucco-fronted Georgian and Victorian townhouses to red-brick mansion blocks, mews cottages and high-value flats carved from former family houses. Many properties are listed, solid-walled and let as corporate or short-term lets with long vacant spells, all of which restrict ventilation upgrades and let condensation and damp take hold unnoticed.

Common causes of mould in Mayfair homes
Solid-walled Georgian terraces with no cavity
Mayfair's period terraces around Berkeley Square and Curzon Street were built with solid brick walls and no cavity, so they rely on breathable lime plaster and good airflow to manage moisture. Modern gypsum plaster, cement pointing or sealed sash windows trap damp inside the wall, and black mould develops on cold internal faces and behind fitted wardrobes long before residents notice a problem.
Listed status limiting ventilation fixes
A large share of Mayfair's stock sits within conservation areas or carries listed building status, meaning extractor fans, trickle vents and external wall changes often need consent before work can proceed. Bathrooms and kitchens fitted into former servants' quarters or basements go without adequate extraction, so steam condenses on tiled walls and ceilings and mould recurs even after redecoration.
Vacant investment flats and mansion blocks
Many Mayfair flats and mews houses are second homes or investment lets left unoccupied for weeks at a time, heating switched off and windows shut. Without regular airflow, moisture from the building fabric and any past leak has nowhere to go, and mould spreads across ceilings, behind curtains and furniture, and around cold single-glazed window reveals before anyone returns to spot it.

Really impressed with the whole experience. The surveyor did a proper, thorough job and didn't rush anything, they got to the root cause of the damp and explained it all clearly. Detailed, professional and reassuring from start to finish. Couldn't recommend them more highly.
