Quick answer: Damp & Mould Solutions UK removes and treats black mould at properties in Longfield, and deals with the moisture driving it rather than painting over it. Mould treatment starts from £300, with a fixed price confirmed from photos or a short video before we attend. A leak is not over when the water stops. Mould can start within 48 hours, so we find the source, dry the structure and treat any mould, all with one company. If the cause of the moisture is not clear, a full damp and mould survey is a separate service, £500, or £450 when you book online and pay the deposit. Call 020 3051 8478.

Leak to dry to treated, one company in Longfield

Longfield's housing runs from Victorian and Edwardian cottages around Longfield Hill to 1930s semis, post-war estates and newer developments in New Barn. Solid brick walls, ageing cavity fill, uPVC replacement windows and tightly sealed modern extensions all trap moisture differently, which is why mould here rarely has one single cause or fix.

Common causes of mould in Longfield homes

Solid-wall cottages in Longfield Hill

The older brick cottages around Longfield Hill and Nurstead were built without a damp proof course or cavity, so groundwater and driving rain move straight through solid walls. This penetrating damp shows up as black mould at skirting level, around chimney breasts and on north-facing external walls, and it keeps returning until the actual water entry point outside is traced and sealed.

1930s and post-war semis with poor ventilation

Many Longfield and Hartley semis had original chimneys blocked and single-glazed windows swapped for sealed uPVC units, cutting off the background airflow the houses were designed around. Bathrooms and bedrooms with no extractor, or one that is never used, build up condensation overnight, and mould develops on cold external walls, ceiling corners and behind wardrobes pushed against outside walls.

New Barn's newer, airtight homes

Newer estate housing in New Barn and around Fawkham is built to modern airtightness standards, which keeps heat in but also traps humidity from cooking, showering and drying laundry indoors. Without extractor fans actually being run, that moist air settles as condensation on cooler surfaces, so mould appears in en-suite bathrooms, behind sofas and beds, and inside fitted wardrobes on external walls.

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 Longfield cost?
Mould treatment starts from £300, with a fixed price confirmed from photos or a short video before we attend. If the cause of the moisture is not clear, a full damp and mould survey is a separate service, £500, or £450 when you book online and pay the deposit. 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. Every job starts by identifying why the mould is there, using a proper damp and mould survey, so the treatment lasts.
