Mould removed
and the cause fixed.
Black mould in bedrooms, bathrooms and behind furniture is the most common problem in London flats — and painting over it doesn't work. We diagnose the cause (condensation, ventilation, leaks or cold bridging), remove and treat the mould, repaint with anti-mould systems and fix the ventilation so it doesn't come back.
What mould treatment
really involves in London.
Most mould in London flats is caused by condensation — warm, moist air hitting cold surfaces in rooms with poor ventilation and heating. It's treatable, but only if the cause is dealt with. Treating and repainting a single room costs £350–£900 + VAT; a whole flat £1,200–£3,000; fixing the ventilation with proper extractors or a PIV unit adds £350–£1,400.
The cost drivers are the extent of the mould, whether plaster needs replacing (heavy long-term growth soaks in), whether there's an actual leak or penetrating damp behind it, and what ventilation work is needed. We test surfaces, check for leaks, and give you an honest diagnosis before quoting.
For landlords, we provide a written report with photos and the works completed, suitable for tenant complaints, council enforcement and compliance with Awaab's Law timescales.
