How much does mould removal cost in Croydon?

It depends on the size of the affected area and what is driving the moisture behind it - a single bathroom wall is very different from whole-flat condensation. Every Croydon job starts with a free, no-obligation assessment and a fixed written quote before any work begins, with no call-out charge. Send us a photo on WhatsApp for a quick initial view.

How quickly can you get to Croydon?

Croydon is inside our same-day London response area. Send photos with the form and we can usually give you a plan and a fixed price the same day, with treatment booked in days, not weeks.

I rent my home in Croydon - should my landlord pay for this?

Often yes. Landlords are responsible for damp and mould caused by disrepair, and Awaab's Law sets strict timescales for social landlords, with the private rented sector next in line. We work for tenants, landlords and letting agents across Croydon, and our documented before-and-after reports work as evidence of proper remediation.

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 Croydon homes

Croydon runs from Victorian terraces around South Norwood and Thornton Heath to the 1960s and 70s high-rise and ex-council stock around the town centre and New Addington. The terraces suffer cold solid walls and blocked-up chimneys that condense moisture; the high-rise flats get condensation mould around windows and in corner rooms where the concrete frame bridges the cold.

Both respond well to proper treatment - and both come back within months if someone just wipes the wall. That is why every Croydon job starts with the cause: condensation, a leak, penetrating damp or ventilation. We treat the mould properly, document it, and tell you in writing what will stop it returning.

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.
