Damp, Mould and Pregnancy: What to Know

This guide is general information, not medical advice for your specific pregnancy — if you have concerns about damp or mould exposure during pregnancy, speak to your midwife or GP.

Why pregnancy is flagged as higher-risk

NHS-affiliated guidance identifies pregnant women, alongside babies, young children and older people, as a group more vulnerable to the health effects of damp and mould exposure. General public health guidance on indoor air quality during pregnancy typically recommends minimising exposure to mould, damp, and poor air quality where reasonably possible, as part of broader advice on a healthy home environment during pregnancy.

Practical steps

• Address the source, not just the visible mould — see our diagnosis guide to identify what type of damp you’re dealing with.
• Get someone else to do any mould cleaning where possible during pregnancy, since cleaning disturbs spores into the air — see our safe mould removal guide for the general safety precautions if you do need to do it yourself, and consider a mask and good ventilation as a minimum.
• If renting, report it promptly — both because it’s the right thing to do generally and because landlords are expected to treat reports involving higher-risk household members with particular urgency under both Awaab’s Law (social tenants) and general fitness-for-habitation obligations (private tenants).
