If a chimney is no longer used, capping it with ventilation keeps rain and birds out. If a stack is unwanted or unsafe, it can be reduced or removed and the roof tiled over.
Removing a chimney needs care: stacks can be supported by internal breasts and shared with neighbours. We assess this first and coordinate any approvals required.

Chimney capping and removal: common questions
Should a capped chimney be ventilated?
Yes. Ventilation helps prevent condensation and damp in the disused flue.
Do I need permission to remove a chimney?
It depends on the property, its location and whether structural changes are involved. Check planning requirements with your local authority; we'll explain what building control or party wall steps may apply.
Can the chimney breast stay if the stack goes?
Removing stacks or breasts affects support. This needs proper assessment and, where structural, appropriate design.
