Leak to dry to treated, one company in Cannon Street
Cannon Street's housing stock is dominated by converted Georgian and Victorian counting houses and warehouses turned into loft apartments, sitting alongside dense post-war and glass-fronted mixed-use blocks. Solid brick party walls, lath-and-plaster ceilings and basement conversions near the buried Walbrook watercourse all slow evaporation, trapping moisture long after a leak has been fixed.

Drying challenges in Cannon Street homes
Solid masonry walls in converted warehouse apartments
Many Cannon Street flats occupy former banking halls and warehouses with thick solid brick walls and original lath-and-plaster linings. These materials soak up water readily but release it slowly, especially where skirting boards, dado rails or panelling trap moisture against the masonry. Without targeted extraction, damp can sit behind surfaces for weeks, encouraging mould growth unseen behind period joinery.
Basements near the buried Walbrook watercourse
Lower ground floor and basement conversions close to the historic course of the Walbrook sit on ground with a naturally high water table. A burst pipe or surface flooding here saturates screed and subfloors quickly, and residual groundwater pressure can keep pulling moisture back into the structure even after pumping out, making standard drying timelines unreliable without monitoring.
Sealed floor voids in modern mixed-use blocks
Newer developments around Cannon Street often use concrete screed floors laid over underfloor heating pipework and service voids. When a leak gets underneath, the sealed void traps trapped moisture against insulation and cabling, hidden from view. Drying demands careful moisture mapping and slow, controlled dehumidification to avoid warping floor finishes or reactivating mould once the area is closed up again.
What our customers say
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.
