Leak to dry to treated, one company in Monument
Monument's residential stock is limited but distinctive: converted merchant houses and warehouse buildings alongside newer riverside and City apartment blocks. Many properties have solid brick walls, low ceilings and restricted ventilation, while older buildings near the Thames often include basements or lower ground floors. This combination of ageing masonry, close-set streets and modern airtight refurbishments creates conditions where condensation and damp readily take hold.

Common causes of mould in Monument homes
Converted warehouse and period apartments
Many Monument flats occupy former merchant houses and warehouse buildings with thick solid brick walls and no cavity. These walls hold moisture rather than shedding it, and once damp gets in from penetrating rain or a plumbing leak it can take a long time to dry out, leaving black mould on internal wall faces, especially where furniture sits close to external walls.
Riverside proximity and penetrating damp
Properties close to the Thames and older buildings around Fish Street Hill and Billingsgate are exposed to driving rain and higher ambient humidity off the river. Where pointing, render or roof detailing has deteriorated, water tracks into walls and ceilings, showing up later as damp patches and mould blooms, often in corners and around window reveals where the fabric stays coldest.
Airtight modern flats with poor extraction
Newer City apartment blocks near Monument and London Bridge are built tight for energy efficiency but often rely on underused or poorly maintained mechanical extractor fans in bathrooms and kitchens. Everyday cooking, showering and drying washing indoors raises moisture levels that have nowhere to escape, so condensation forms on cold surfaces and mould develops behind wardrobes, in en suite corners and along ceiling edges.
