Garage Demolition: Options & Costs 2026
For most homeowners a full garage demolition by a demolition or building contractor is the safest, quickest option — typically £600–£2,500. A partial demolition or strip-back suits a renovation, while DIY only makes sense for a small timber garage with no asbestos. Here is how the options compare and how to choose.
Garage demolition options compared
A demolition contractor is fastest and best for concrete, brick or asbestos-clad garages — they bring the plant, manage waste and carry the right insurance. A general builder often handles a straightforward garage as part of a wider project and can rebuild or landscape afterwards. DIY is only sensible for a small timber or lightweight garage with no asbestos, where you still have to hire a skip and dispose of waste legally. The right route depends on the garage material, asbestos risk and what you are doing with the space next.
Full vs partial demolition
A full demolition clears the garage to slab level (or below, if the base comes up too) and is the usual choice before a rebuild, extension or landscaping. A partial demolition or strip-back keeps the sound structure — often the walls or frame — and removes only the roof or a failed section, which suits a renovation or conversion. Partial work can be cheaper but needs care to keep the retained structure safe and weathertight.
Garage demolition cost 2026
In 2026, budget around £400–£900 for a prefab sectional garage, £900–£1,800 for a single brick or concrete garage, and £1,800–£3,500 for a large or attached one. Asbestos removal adds roughly £300–£1,000, and breaking out the concrete base another £300–£800. See our garage removal cost guide for the full breakdown.
