Damp and mould removal in York

Old buildings, modern materials

Many York houses were built with lime mortar and plaster, which let moisture evaporate. Replacing them with cement or gypsum can push damp up the wall or into rooms. Injected damp-proof courses are often sold where the real fix is removing impermeable materials and improving drainage outside.

Renting

One in five York households rents privately. Landlords must fix damp and mould that makes a home unfit to live in. City of York Council tenants are also protected by Awaab's Law, which sets time limits for social landlords to investigate and repair serious damp.

Report it in writing and take dated photos. Our window condensation guide helps with the day-to-day.

Cleaning safely

Small patches can be cleaned with a mould spray; our guide on removing mould from walls has the details. Wear gloves and keep the window open.

What to expect from a survey

A good surveyor checks moisture readings at different heights, looks at gutters, downpipes and ground levels outside, and asks about heating and drying habits. In a period house, they should recognise lime plaster and solid walls and not recommend treatments that trap moisture. Ask for a written report that says what the cause is, not just what to buy.
