Damp, mould & leak services in Richmond

Richmond's housing stock spans Georgian townhouses on Richmond Hill, Victorian and Edwardian terraces throughout East Sheen and Mortlake, and post-war semis in Ham and Whitton. This mixture of age, construction method and conversion history creates persistent vulnerabilities to rising damp, condensation and roof leaks, particularly in older properties with solid brick walls and no cavity insulation.

Common damp problems in Richmond homes

Rising Damp in Georgian and Victorian Terraces

Many of Richmond's older terraces in areas such as Richmond Hill, Petersham and Mortlake were built without functional damp proof courses, or have courses that have since deteriorated. Groundwater can wick steadily upward through solid brick walls, leaving salt tide marks, peeling plaster and persistent musty odours at low level, often misdiagnosed as condensation by homeowners.

Penetrating Damp in Kew and East Sheen Conversions

Large Victorian and Edwardian properties in Kew and East Sheen are frequently divided into flats, creating complex roof and parapet details that are poorly maintained across multiple ownerships. Shared flat roofs, inadequate flashings around chimney stacks and blocked internal gutters allow rainwater to penetrate outer walls, causing damp patches that migrate internally and damage plasterwork over successive winters.

Hidden Leaks in Post-War Housing Around Ham and Whitton

Post-war semis and terraces across Ham and Whitton often conceal ageing copper and early plastic pipework within floor voids and wall chases. Slow pinhole leaks from these systems go undetected for months, saturating timber joists and sub-floor insulation, encouraging mould growth and rot before any visible staining appears at ceiling or wall surfaces.

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.
