Damp, mould & leak services in Croydon

Croydon's housing stock spans Victorian and Edwardian terraces in areas like Norbury and Thornton Heath, inter-war semis across Shirley and Coulsdon, post-war council blocks in central Croydon and New Addington, and modern flats in the town centre. This variety of ages and construction methods creates persistent vulnerabilities to damp ingress, condensation and water penetration.

Common damp problems in Croydon homes

Condensation and Mould in Victorian Terraces

The densely packed Victorian and Edwardian terraces throughout Norbury, Selhurst and Addiscombe were built with solid brick walls and minimal ventilation. Modern draught-proofing and double glazing fitted retrospectively traps moisture indoors, encouraging condensation on cold external walls. Black mould growth around window reveals, behind wardrobes and in corner junctions is a common consequence in these properties.

Penetrating Damp in Inter-War Semis

The wide stock of 1920s and 1930s semi-detached houses across Shirley, Sanderstead and Coulsdon frequently suffers from penetrating damp caused by deteriorating mortar joints, failed cavity wall ties and aging parapet or chimney flashings. Driving rain from the exposed higher ground in the south of the borough pushes moisture through the outer leaf, leaving damp patches on internal walls particularly after prolonged wet weather.

Hidden Leaks in Post-War Flatted Developments

Central Croydon, Waddon and New Addington contain significant numbers of post-war concrete and system-built flat blocks. Aging communal pipework, flat roofing membranes that have deteriorated over decades, and poorly maintained expansion joints allow water to track through the structure largely unseen. Residents often discover leaks only once ceiling staining, damaged plasterwork or rising damp at skirting level has already become pronounced.

Really impressed with the whole experience. The surveyor did a proper, thorough job and didn't rush anything, they got to the root cause of the damp and explained it all clearly. Detailed, professional and reassuring from start to finish. Couldn't recommend them more highly.

★★★★★

Very professional and organised I must say came out and completed the work very efficiently customer service was excellent. Definitely recommend this damp and mould service to anyone looking for a job done correctly. :)

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.
