Damp, mould & leak services in Lewes

Lewes contains a dense mix of 18th and 19th century flint and brick terraces, Georgian townhouses, Victorian workers' cottages and post-war council stock. The town's position within the Ouse valley means many properties sit on low-lying ground, making rising damp, flood ingress and persistent structural moisture particularly common problems across different neighbourhoods.

Common damp problems in Lewes homes

Rising and Penetrating Damp in Flint-Built Terraces

Many older properties in areas such as Cliffe and Southover were constructed using traditional Sussex flint with lime mortar. As original mortars degrade over time, they allow rainwater to penetrate external walls readily. Without functioning damp proof courses, ground moisture also rises through flint rubble foundations, causing persistent damp patches at skirting level, salt deposits on internal plasterwork and recurring mould growth.

Flood-Related Moisture and Hidden Structural Leaks

Lewes has a well-documented history of flooding, particularly affecting lower-lying streets near the River Ouse around Brook Street and Malling. Even properties that escaped direct flood water often retain elevated moisture levels within floor joists, subfloor voids and cavity walls long after flood events. Hidden leaks from ageing pipework within these damp subfloor spaces frequently go undetected until significant timber decay or mould colonisation becomes visible indoors.

Condensation and Mould in Victorian and Post-War Housing

Victorian terraces throughout the Landport and Wallands areas, alongside mid-20th century housing stock in Nevill, commonly suffer from poor thermal performance in solid walls and inadequate ventilation. Retrofitted double glazing reduces air movement without adding mechanical extraction, causing condensation to accumulate on cold wall surfaces and around window reveals. This sustained moisture creates ideal conditions for black mould growth in bedrooms, bathrooms and kitchen areas.

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