Leak to dry to treated, one company in Forest Hill
Forest Hill's housing runs from grand Victorian villas near the Horniman Museum to dense terraces off Dartmouth Road and 1930s semis on the higher ground towards Sydenham Hill. Solid brick walls, lime mortar and suspended timber floors are common, and many properties sit on sloping, clay-heavy ground, all of which slow drying and hide moisture long after a leak or flood.

Drying challenges in Forest Hill homes
Solid brick walls and lime mortar in Victorian terraces
Many Forest Hill terraces near Perry Vale and Dartmouth Road have solid nine-inch brick walls built with lime mortar rather than cement and a damp-proof membrane. These walls absorb water readily after a burst pipe or roof leak and release it slowly, so plaster can stay damp for weeks. Drying too quickly with high heat risks cracking lime plaster and pushing moisture deeper into the brickwork.
Suspended timber floors and hidden voids in converted villas
The larger Victorian villas around Honor Oak and Sydenham Hill were often split into flats, leaving suspended timber ground floors and boxed-in voids between original joists and later partition work. Leaking supply pipes or overflowing baths send water into these enclosed spaces, where it sits against joists and skirting unseen. Without opening the void or using targeted air movement, trapped moisture leads to swelling, rot and mould well after the surface looks dry.
Concrete screed extensions and rendered 1930s semis
1930s semis on the Sydenham Hill and Kirkdale side of Forest Hill, plus rear extensions added to older terraces, often have solid concrete screed floors and cement render finishes. These materials hold water for longer than timber and lime, and non-breathable renders trap moisture against the wall rather than letting it evaporate outward. Left unchecked, this creates ideal conditions for secondary mould behind kitchen units and skirting in these extended areas.

Jensen B, via Google
I recently used a damp and mould specialist company and was extremely impressed with the service from start to finish. From the initial survey, they were knowledgeable, thorough, and took the time to clearly explain the cause of the issue rather than just treating the symptoms.
