Damp and mould specialists
Damp and mould go together - and treating one without the other never lasts. We diagnose the damp, remove the mould safely and fix the cause, for homeowners, landlords and housing associations across London and the UK, backed by a 12-month guarantee.
One team for the damp and the mould
Most mould problems are really moisture problems. Rising damp, penetrating damp, leaking plumbing or plain condensation all leave walls cold and wet - and mould follows. As damp and mould specialists we treat the pair as one job: identify the type of damp, fix or advise on the source, remove the mould safely, and protect the surface so it stays clean. With 8,500+ jobs completed, we know exactly what UK housing stock throws at us.
Landlords and housing associations use us because our surveys and treatment records are written to stand up to scrutiny under Awaab's Law and HHSRS. Read our guide to Awaab's Law and mould for landlords or see our specialist mould removal service - including mould removal in London.

Awaab's Law compliance, documented
Since October 2025, social landlords must investigate significant damp and mould within 10 working days, share written findings with the tenant within 3 working days of completing that investigation, and complete safety works within 5 working days - with emergency hazards made safe within 24 hours. We help housing associations and landlords hit those deadlines: fast attendance, photographic evidence, clear findings and completed works reports for every case.
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.
Backed by a 12-month guarantee
If treated mould returns within 12 months, we come back and put it right. Accredited, insured and DBS-checked teams on every job.
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.

Frequently asked questions
- What is the difference between damp and mould?
- Damp is the moisture problem - rising damp, penetrating damp or condensation. Mould is the visible symptom that grows where that moisture sits. We diagnose and treat both: if you only clean the mould without fixing the damp, it comes back.
- Are you a damp and mould specialist for housing associations?
- Yes. We work with leading housing associations including L&Q and Peabody, delivering documented damp and mould surveys, treatment and post-work evidence that support their Awaab's Law and HHSRS obligations.
- What are the Awaab's Law timescales for damp and mould?
- For social landlords, significant damp and mould hazards must be investigated within 10 working days, written findings sent to the tenant within 3 working days of completing the investigation, and safety works completed within 5 working days of the investigation. Emergency hazards must be made safe within 24 hours.
- Do you treat rising damp and penetrating damp as well as condensation?
- Yes. We identify which type of damp is driving the problem - rising damp, penetrating damp, plumbing leaks or condensation - then treat the source and remove any mould safely, with a fixed quote before work starts.
- Is the work guaranteed?
- Yes. Every damp and mould treatment comes with our 12-month guarantee - if the mould we treated returns within 12 months, we come back and put it right.
