This page provides general practical guidance and does not replace project-specific legal, engineering, planning, ecological, asbestos or waste advice.
The short answer
There is no reliable universal price for garage demolition. A written quotation should reflect the specific structure, roof materials, access, waste route and agreed handover condition. A small detached garage with straightforward access is a different scope from an attached structure with a suspected asbestos-containing roof, a slab to remove or a long manual carrying distance.
Why it matters
The variables that affect cost are often invisible in a photograph. Roof construction, reinforcement in the slab, proximity to retained structures and the distance from the work area to the loading point all affect the method, programme and waste arrangement. A price that does not account for these is not a reliable basis for planning.
Information that may be needed
Photographs of all elevations and the roof (where safe), approximate dimensions, roof-material information, access details and any known service information help establish the scope. If the garage is attached, a photograph showing the junction with the retained structure is useful.
What can affect the scope
Size and construction, attached or detached status, roof covering and asbestos risk, slab and foundation removal, access for skips or plant, manual carrying distance, waste type, service disconnections and required handover condition all matter.
When specialist input may be needed
An asbestos professional may be required where roof or other materials need sampling before work begins. A utility provider may need to confirm service isolation where services run to or through the structure.
