Damp, mould & leak services in Norbury

Norbury is dominated by Edwardian and early Victorian terraced houses, many converted into flats, alongside interwar semi-detached properties and post-war council-built stock. The age and density of this housing mix, combined with frequent subdivision of larger properties, creates persistent conditions for rising damp, condensation, and undetected roof and plumbing leaks.

Common damp problems in Norbury homes

Rising Damp in Edwardian Terraces

Many of Norbury's Edwardian terraced houses were built without adequate damp-proof courses, or have original bitumen courses that have since deteriorated. Groundwater wicks upward through solid brick walls, causing tide marks, flaking plaster, and salt deposits at low level. Properties along older streets near Norbury Park are particularly susceptible due to clay-heavy subsoil retaining moisture.

Condensation and Mould in Converted Flats

The widespread conversion of larger Norbury terraces into self-contained flats has created poorly ventilated spaces with reduced airflow and inadequate extract fans in bathrooms and kitchens. Tenants in upper and basement flats frequently report black mould growth on external walls and window reveals, driven by warm indoor air meeting cold, uninsulated Victorian brickwork during autumn and winter months.

Penetrating Damp from Ageing Roofs and Gutters

Norbury's interwar semi-detached properties commonly have original clay pantile or plain tile roofs alongside cast-iron guttering that has corroded or pulled away from fascias over decades. Blocked or leaking gutters allow water to saturate external brickwork and penetrate into first-floor rooms and loft spaces, often going unnoticed until significant internal staining or timber damage has already occurred.

What our customers say

★★★★★

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.

I have been dealing with damp and mould for years but these guys were able to come in and resolve the problem quickly and professionally. Their prices were fair and reasonable and they got the job done clean. 10/10 would use again and would recommend.

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.
