Damp, mould & leak services in Greenwich

Greenwich contains a genuinely varied housing stock, from grand Georgian and Victorian terraces around Blackheath and Maze Hill to post-war council estates in Woolwich and Thamesmead, alongside Edwardian semis in Eltham and modern riverside apartments near the Thames. This mix of ages, construction methods and tenure types creates a wide range of damp, mould and leak vulnerabilities that differ considerably street by street.

Common damp problems in Greenwich homes

Solid Wall Penetrating Damp in Georgian and Victorian Terraces

The Georgian and Victorian properties concentrated around Blackheath, Maze Hill and Westcombe Park were built with solid brick walls that offer no cavity to drain or dry out moisture. When pointing deteriorates or render cracks, rainwater soaks directly into the masonry. Internally this presents as damp patches, tide marks and peeling plaster, often mistaken for condensation but driven entirely by water ingress from outside.

Flat Roof and Deck Leaks on Post-War Estates

Large sections of Thamesmead, Kidbrooke and parts of Woolwich were developed using system-built construction with flat or low-pitched roofs and deck access walkways. These roofing membranes and concrete deck surfaces age and crack, allowing water to track down into communal stairwells and individual flats. Residents in upper-floor and top-floor properties frequently report ceiling staining and mould growth that stems from poorly maintained flat roof details.

Rising Damp and Sub-Floor Moisture in Edwardian Semis

Edwardian semi-detached and terraced houses in Eltham, Charlton and Lee commonly have suspended timber ground floors and shallow damp proof courses that have deteriorated over more than a century. Blocked sub-floor air bricks, raised external ground levels and the area's clay-heavy soil all contribute to moisture accumulating beneath floors and wicking upward through ground-floor walls, causing skirting board decay, plaster salting and persistent musty odours.

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.

Tip: If a damp patch keeps coming back after redecorating, it is almost always a symptom, not the problem. A survey that finds the source first saves paying for the same repair twice.
