Damp, mould & leak services in Marylebone

Marylebone's housing runs from grand Georgian terraces and mansion blocks around Montagu and Bryanston Squares to mews cottages and post-war conversions near Lisson Grove. Many properties have solid brick walls, single-glazed sash windows and bathrooms squeezed into former box rooms, so heat loss and poor ventilation combine readily to create the damp, still air that black mould needs.

Common causes of mould in Marylebone homes

Cold solid walls in subdivided Georgian houses

Many Marylebone terraces were carved into flats decades ago, leaving solid nine-inch brick walls with no cavity insulation. These walls run cold internally, especially on north-facing bedroom elevations, and condensation forms wherever airflow is restricted. We regularly find black mould creeping up behind wardrobes, headboards and chests of drawers pushed against external walls in these converted flats.

Windowless bathrooms in mansion block conversions

Mansion blocks around Baker Street and Dorset Square were often reconfigured with internal bathrooms that have no external wall or opening window, relying entirely on mechanical extraction. Where fans are undersized, blocked or simply switched off, steam has nowhere to go and settles on ceilings and tiling grout. We treat the mould and check extraction rates so moisture actually leaves the building rather than migrating into neighbouring rooms.

Penetrating damp in lower ground and mews properties

Lower ground floor flats and mews houses near Lisson Grove sit close to pavement level, with old lightwells, ageing tanking or perished pointing that let ground moisture track through external walls. This shows as mould around window reveals, skirting boards and behind fitted furniture in bedrooms. We identify the specific entry point, whether it is failed damp-proofing or a blocked lightwell drain, before treating the mould itself.

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 Marylebone 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.
