What a damp and mould specialist does
Damp and mould specialists diagnose the cause of damp, whether condensation, penetrating damp from outside, rising damp or a leak, then treat it and remove the mould. The diagnosis is the whole job, so in London be wary of anyone who quotes for a damp proof course before finding the cause, and ask for a written report you can keep.

Frequently asked questions
Is winter mould just condensation?
Often it is: black mould on cold walls, window frames and behind furniture usually comes from moisture in the air settling on cold surfaces. Ventilating while cooking and drying clothes, and keeping rooms evenly warm, helps. Damp that spreads in a tide line from the floor, or a patch that stays wet in dry weather, points to a leak or rising damp and needs a survey.
Is it condensation or damp?
Condensation shows as black mould in corners, behind furniture and on cold walls, worst in winter, and comes from moisture inside the house. Penetrating damp follows rain and shows as patches that grow after wet weather. Rising damp is rare and shows as a tide mark low on ground floor walls.
Do I need a damp survey?
For anything beyond obvious condensation, yes, and it should be independent of the treatment. Some businesses survey free and then sell the treatment, which is a conflict. A written report with moisture readings and photos is what you want.
How do I stop mould coming back?
Mould grows where there is moisture and little air. Fix the source, improve ventilation with extractor fans that actually run, keep some heat in cold rooms, and clean the mould off properly rather than painting over it.

Are the damp and mould specialists on this page vetted?
Not yet.

Every listing shows its real Google rating and review count where one exists. We do not check registers or insurance yet, so ask for a Gas Safe or NICEIC/NAPIT number and check it yourself.
What should I check before I hire a damp and mould specialist?
Ask for a written quote and what it includes, who will do the work, whether they are insured, and any registration the trade needs, such as Gas Safe for gas work or a Part P scheme for electrics. Never pay the full amount up front.
