How much does site protection cost in a demolition?

Site protection in a demolition is far too often forgotten when quoting, treated as a minor extra when on facades facing the public highway it can be a direct legal requirement of the works permit.

Protective sheeting: a municipal requirement, not just good practice

Protective sheeting or protective scaffolding protects the surroundings (street, neighbours, adjoining areas) from dust and flying rubble during the demolition. On facades facing the public highway, protection is not just advisable, it is usually a requirement of the municipal works permit itself: check it before starting, not after someone complains or the council stops the work.

Interior protective plastic: seal the edges

Protective plastic covers furniture, floors or areas of the home that aren't part of the demolition, to prevent dust and damage. The detail that gets forgotten: demolition dust gets through any gap left unsealed. Seal the edges of the plastic properly with tape, don't leave it just resting or loose over the furniture — a badly sealed plastic protects much less than it seems at first sight.

Signage and fencing: not optional with third-party access

Safety signage and fencing physically delimit the demolition area from the passage of people unconnected with the work, inside or outside the building. On jobs with access by neighbours or the public nearby, it isn't optional: it's the first thing checked if an incident occurs and there was no clear delimitation of the risk zone — an omission that can have serious legal consequences, not just reputational.

Frequently asked questions

Is it mandatory to protect the facade in any demolition? On facades facing the public highway, it is usually a requirement of the municipal works permit, not an option — worth checking before starting.

Why didn't my protective plastic stop dust getting in? Almost always because of edges not sealed with tape; plastic that is just resting leaves gaps through which the fine demolition dust gets in.

Is it necessary to fence off the area if the job is in a home with no third-party access? It's less critical, but if there is any access by neighbours or the public nearby, signage and fencing are the first check after an incident.

Conclusion

Treating site protection as a minor item is a frequent mistake that can cost dearly: from a stoppage for breaching the municipal permit to a claim for damage to badly protected surfaces. Quoting sheeting, well-sealed plastic and fencing as their own items, not as an implicit extra, protects both client and professional.
