Do you cover all London boroughs?

Yes. We cover all 32 London boroughs and the City, from inner-London flats to outer-London houses, with operatives positioned across North, South, East, West and Central London for a fast response.

Do you work with London housing associations on damp and mould?

We do. We work with leading housing associations including L&Q and Peabody, delivering documented mould removal that supports their damp-and-mould and Awaab's Law obligations.

How much does mould removal cost in London?

It depends on the size of the affected area, how far the mould has spread and what is driving the moisture behind it - a single bathroom wall is very different from whole-property condensation. That is why every London job starts with a free, no-obligation assessment and a fixed quote before any work begins, with no call-out charge. Send us a photo on WhatsApp for a quick initial view.

Can you remove black mould from a rented flat in London?

Yes. A large share of our London work is rented flats and houses. We provide documented before-and-after evidence that landlords, letting agents and housing associations can use to meet their damp-and-mould duties under Awaab's Law, and we treat the moisture source so it does not simply return when the tenancy changes.

What is the most common cause of mould in London flats?

In most London flats it is condensation rather than a leak or rising damp. Warm, moist air from cooking, showering and drying clothes indoors hits cold, single-skin external walls and period windows, then settles as water where black mould can grow. We identify whether you are dealing with condensation, penetrating damp or a leak, then treat the actual cause - the only way to keep the mould from coming back.

What is your 12-month guarantee?

If mould we have treated returns within 12 months, we come back and put it right. We treat the moisture source behind the mould, not just the surface, which is why we can stand behind the work.

How quickly can you come out?

We aim to respond fast and offer a free, no-obligation assessment. Send us a photo on WhatsApp for an even quicker initial view.

Why mould is so common in London homes

London's housing is dominated by Victorian and Edwardian terraces, period conversions and high-density flats - many with single-skin walls, original windows and little built-in ventilation. Add the city's huge private-rented and social-housing stock, where reporting damp can be slow, and you get the perfect conditions for condensation and black mould to take hold on cold external walls, behind furniture and around windows.

We work daily across London for homeowners, landlords and housing associations, and we know the local stock - from converted flats in Hackney and Camden to ex-council blocks in Newham and Croydon. With Awaab's Law raising the bar on damp and mould in rented homes, we deliver documented, compliant removal that stands up to scrutiny.

Our mould removal process

A proven four-step process that treats the cause, not just the symptom - so the mould stays gone.

1
Assess
We inspect the affected areas and find the moisture source driving the mould - not just the visible growth.
2
Contain
We seal off the area so spores don't spread to clean rooms while we work.
3
Remove
We safely treat and remove all mould using professional-grade methods, then anti-microbial protect the surface.
4
Restore & prevent
We repair any damage and advise on ventilation and damp control so the mould doesn't come back - backed by our 12-month guarantee.

Before. After. No filter.

We don't paint over mould. Every job: find the cause, kill the spores, fix the moisture source, then refinish - anything else just comes back.

Why untreated mould is a real risk

Mould releases allergens and mycotoxins that can trigger coughing, wheezing, throat and skin irritation, and asthma attacks - a particular danger for children, the elderly and anyone with a respiratory condition. Left alone, it also damages plaster, timber and decor, turning a small problem into an expensive one.

Acting early protects both your health and your property. We deal with mild surface mould and severe, widespread infestations alike.
