Damp, mould & leak services in Catford

Catford's housing stock ranges from Victorian and Edwardian terraces around Rushey Green and Ladywell to 1930s semis, post-war estates near Bell Green, and converted flats let as HMOs. Solid brick walls, ageing damp proof courses and poorly ventilated conversions mean condensation and penetrating damp are common, particularly where original chimney breasts, sash windows or flat roof extensions have been altered without proper repair.

Common causes of mould in Catford homes

Chimney breasts and solid walls in Victorian terraces

Many Catford terraces around Rushey Green and Ladywell retain original chimney breasts and solid brick external walls with no cavity. Once a flue is capped or rendering cracks, moisture tracks through the brickwork and appears as black mould on the chimney breast, behind wardrobes pushed against outer walls, and along skirting boards, often mistaken for rising damp when it is actually penetrating damp.

Poor ventilation in converted flats and HMOs

Catford has a large number of Victorian and Edwardian houses split into flats, many let as shared accommodation. Bathrooms without working extractor fans, bedrooms with blocked airbricks, and kitchens venting into hallways create trapped humidity. This shows up as black spot mould around window reveals, on north-facing bedroom walls and in bathroom corners, worsened by multiple occupants generating moisture in a small space.

Flat roof extensions and 1930s semis losing render

The 1930s semis and post-war stock around Bellingham, Downham and Bell Green often have rear flat roof extensions or pebbledash rendering that has cracked with age. Water tracking in through a failed roof covering or damaged render gets trapped in the cavity, leading to mould staining on ceilings and upper wall corners that reappears each winter until the actual moisture entry point is repaired.

Tip: Wiping mould off with bleach and repainting hides it for a few weeks, then it returns. Mould is a moisture problem, so unless the condensation, damp or leak feeding it is fixed, it always comes back.

Frequently asked questions

How much does mould removal in Catford cost?
We confirm the price on a written quote once we understand the problem. Send us photos or a short video and we will quote from that. If the cause of the moisture is not clear, we start with a Damp, Mould and Water Damage Assessment to find it. Treating the surface without the source means the mould returns.
Is black mould in my home dangerous?
Black mould affects indoor air quality and is best removed promptly. We treat the mould and fix the moisture driving it, so the problem is dealt with at the cause.
Will the mould come back after treatment?
Not if the moisture source is fixed. We find and address the cause, whether condensation, penetrating damp or a leak, rather than just cleaning the surface.
Do you find what is causing the mould?
Yes. We identify why the mould is there before treating it, so the treatment lasts. If the cause is not clear, we start with a Damp, Mould and Water Damage Assessment.
