Damp, mould & leak services in Lewisham

Lewisham's housing spans Victorian and Edwardian terraces in Ladywell and Brockley, 1930s semis around Grove Park and Downham, postwar council estates near Catford, and new-build flats along the Deptford and New Cross riverside. This mix of solid-wall Victorian brick, poorly insulated interwar cavity walls and dense modern conversions creates varied damp, mould and leak problems, from failing pointing to condensation trapped in poorly ventilated flats.

Common damp problems in Lewisham homes

Solid-wall terraces in Ladywell and Brockley

Many Victorian terraces here were built without cavity walls or damp-proof courses, relying on lime render and breathable finishes. Later cement render and gypsum plaster trap moisture, pushing damp up from ground level and causing black mould around skirting boards and chimney breasts, particularly in ground-floor rooms backing onto small rear gardens.

Interwar semis around Grove Park and Downham

The 1920s and 1930s cavity-wall semis common across the Downham estate and Grove Park often have deteriorated wall ties, blocked cavities or bridged cavities from later loft conversions and extensions. This lets water track through to internal walls, showing up as damp patches near window reveals and in extended kitchens where original ventilation was removed.

Converted flats and new-builds near Deptford and New Cross

Riverside regeneration and Victorian houses split into flats around New Cross and Deptford leave many properties with limited through-ventilation and shared, often neglected roofs or parapet gutters. Residents frequently report condensation mould on north-facing bedroom walls and recurring leaks from communal plumbing or flat roofs above top-floor conversions.

What our customers say

★★★★★

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.
