Mould keeps coming back unless the moisture behind it is dealt with. Ideal Response's mould removal specialists remove mould safely, investigate the cause and give you a record of the work, for homeowners, landlords and businesses across Kent, London and the South East. Visits are booked as planned appointments, with same day visits where possible.
Affected areas sealed off so spores do not spread.
Spores captured and mould removed with fungicidal treatment.
A fine fungicidal mist treats airborne spores.
An optional damp survey identifies the moisture source.
Before-and-after photos and a written record for landlords.
More than about one square metre in total, roughly a bath towel, or growth in several rooms.
Breathing problems, irritation or headaches that ease away from the property.
Mould on plasterboard, insulation or carpet, or a musty smell with no visible source.
Mould returning quickly after cleaning, or with water staining.
Landlords need records of the work to show they have met their duties under the Homes (Fitness for Human Habitation) Act and, for social housing, Awaab's Law.

Damp and mould is one of the hazards assessed under the Housing Health and Safety Rating System. Mould spores can cause breathing problems, allergic reactions and asthma attacks, and the risk is greater for children, older people and anyone with a weakened immune system. Read: mould toxicity symptoms.
Mould and damp feed on organic materials, including the timber in floors, joists and roofs. Left alone, they cause:
The hidden damage costs far more to put right than the visible marks, so act early.
A clear, recorded response protects tenants and landlords.
Cost depends on the size of the affected area, the materials involved and the cause of the damp. You receive a fixed quote after assessment.
Social landlords must also meet the investigation and repair timeframes set by Awaab's Law.

Standards we work to: HHSRS, Awaab's Law, HSE and COSHH regulations. Social landlords must also meet the investigation and repair timeframes set by Awaab's Law.
We remove mould and can investigate and dry the cause, including tracing a hidden leak. We do not repair plaster, timber or insulation. Removing mould does not stop it returning if the moisture problem is not fixed.
| Cost factor | Why it matters |
|---|---|
| Area affected | A small patch costs less than growth across several rooms |
| Materials | Mould in porous materials may need removing; replacement is for your builder |
| Cause of the damp | Condensation, a leak or penetrating damp change the scope |
| Access | Hard-to-reach areas and larger commercial properties take longer |
