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 |


Mould is a symptom of too much moisture. If you remove it without finding the cause, it usually comes back. A mould survey finds out why the mould is growing, so the right thing gets fixed.
Whether there is likely to be hidden mould where you cannot see it, from dust that reflects months of history.
How many mould spores are in the air compared with outside on the same day.
Most surveys need no extra tests. We only suggest one if the result would change your next step, and agree it before the visit so it is done on the day.
From £295, usually up to 1.5 hours on site (depending on the size of the property and the affected area), with a report within 5 working days. If we then remove the mould, the survey fee is credited against the work. If the cause looks like penetrating damp, rising damp or a leak, we will recommend a damp survey or leak detection instead.
Mould grows where moisture lingers: bathrooms, kitchens, lofts, around windows, in basements and behind furniture where air cannot move. The usual causes are condensation, penetrating damp and hidden leaks; it can also follow a flood or burst pipe.
If the moisture is not dealt with, the mould comes back. That is why we investigate the cause as well as removing the growth.
Call a specialist if mould covers more than about one square metre, keeps returning after cleaning, or is affecting anyone's health.
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.
Visible damage has been cleaned, 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.
Mould growth is a recognised hazard under the Housing Health and Safety Rating System. It should be removed and its cause corrected, which is why we investigate the moisture behind it as well as removing the growth.
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.
