Damp and mould remediation in London
If damp and mould reports in London keep coming back, the cause probably has not been fixed. We find it, fix it and check the result.
We take on damp and mould remediation for social landlords across London: housing associations, councils, ALMOs and supported housing providers in all 33 council areas, to the rules that apply in England.

Which rules apply in London?
Social homes in England must meet the Decent Homes Standard, enforced through the Regulator of Social Housing's Safety and Quality Standard. A reformed standard, confirmed in January 2026, must be met by 2035 at the latest.
What does it cost in London?
Our guide range for a typical damp and mould case (one or two rooms, mould treatment and an extract fan) in London is £550–£1,400 per home. That is the UK range of £450–£1,150 (derived from published totals) adjusted by a regional cost factor of 1.22 (VOA Rating Cost Guide 2026: inner London 1.17–1.32, outer London 1.08–1.26); figures are before VAT where the source states it. Every job is priced after survey; specification, access and the condition of the homes will move the figure.
How do we deliver it?
Where a cause sits outside the home, such as a gutter, a roof or a communal leak, we price that work too, because the mould inside will come back if it is left.
Common questions
Which council areas in London do you cover for damp and mould remediation?
All 33: Barking and Dagenham, Barnet, Bexley, Brent, Bromley, Camden, City of London, Croydon, Ealing, Enfield, Greenwich, Hackney, Hammersmith and Fulham, Haringey, Harrow, Havering, Hillingdon, Hounslow, Islington, Kensington and Chelsea, Kingston upon Thames, Lambeth, Lewisham, Merton, Newham, Redbridge, Richmond upon Thames, Southwark, Sutton, Tower Hamlets, Waltham Forest, Wandsworth, Westminster.
Is condensation the tenant's fault?
Rarely on its own. National guidance on damp and mould tells landlords to look at the building first: ventilation, insulation, heating and repair. We approach every case on that basis.
Do you just treat the mould?
We treat it, but we also find and fix the cause. Mould that is washed off without dealing with ventilation, cold spots or leaks usually returns within weeks.
