Damp and mould remediation in a social home

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.

Which rules apply in Belfast?

Damp and mould is dealt with under landlords' repair obligations and the Decent Homes Standard. The Department for Communities consulted in 2025–26 on a revised standard that includes a repair-timescale baseline.
