Common Questions From Homeowners
Clear answers about chimney removal, structural support, building control and project timelines.
In most cases, yes. Chimney breast removal is structural work, so Building Control will normally need to inspect the work and confirm it meets the Building Regulations. We can arrange the application, inspections and completion certificate as part of the job.
Usually, yes. A structural engineer checks what the chimney supports and specifies any steelwork, padstones or other support that is needed. Their calculations are also normally required by Building Control.
Yes. We can manage the engineer, structural calculations, Building Control application, site inspections and the final completion certificate, so you are not left coordinating several different people yourself.
That depends on the layout of the property and what remains above the section being removed. Many chimney breast removals need steel support, but the exact arrangement must come from the structural engineer rather than being guessed on site.
Yes. We regularly remove chimney breasts over two floors. The work is planned in the correct sequence, with temporary support and permanent steelwork installed where the engineer requires it.
Yes. We can remove a redundant chimney stack and complete the necessary roof repairs and weatherproofing. Access, party wall matters and the structural design are checked before the work starts.
