Damp, mould & leak services in Hersham

Hersham contains a varied housing stock ranging from interwar semi-detached properties and post-war council-built terraces to Victorian cottages near the village centre and modern infill developments. This mix of construction eras, combined with Hersham's relatively high water table and proximity to the River Mole, creates persistent conditions that encourage damp ingress, mould growth and concealed leaks.

Common damp problems in Hersham homes

Rising and Penetrating Damp in Interwar Semis

Many of Hersham's interwar semi-detached homes were built with shallow cavity walls or solid brick construction, and original damp-proof courses have often deteriorated or been bridged by raised external ground levels. Owners frequently report damp patches appearing along ground-floor walls, particularly in hallways and front reception rooms, where moisture migrates upward or inward unchecked throughout wetter months.

Condensation Mould in Post-War Terraced Properties

The post-war terraced housing stock found around the Rydens area of Hersham was constructed with limited insulation and minimal ventilation provision. As residents upgrade draught-proofing without addressing airflow, moisture from cooking and bathing becomes trapped indoors. Black mould growth commonly appears on north-facing bedroom walls, inside fitted wardrobes and around window reveals where surface temperatures drop lowest.

Roof and Gutter Leaks in Burwood Park Detached Homes

Larger detached properties within and around Burwood Park feature complex rooflines with multiple valleys, dormers and flat-roof sections that are prone to pooling water and failing flashings. Blocked or deteriorated guttering allows water to saturate brickwork behind fascias, leading to penetrating damp inside upper-floor rooms. These leaks often go undetected until ceiling staining or timber decay becomes visible internally.

★★★★★

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.
