One of the most common questions we get from homeowners planning a knockdown-rebuild or demolition project in Sydney is: how long will it take? The short answer is 3–7 days for the physical demolition work, but the full process from booking to site handover is typically 3–6 weeks. Here's why.
The Full Demolition Timeline in Sydney
1. Quote and booking (1–2 weeks)
After you contact us, we arrange a free site assessment within 1–2 business days. We then provide a written quote within 48 hours. Once you accept, we schedule the job — typically 1–2 weeks out depending on current workload and your timeframe.
2. Pre-demolition checks (1–2 weeks)
Before demolition begins, several things need to happen:
- Utility disconnections — Water, gas, electricity and telecommunications must be disconnected by the relevant authorities before demolition begins. This takes 5–10 business days typically. You or your demolition contractor initiates this.
- Asbestos assessment — If the property was built before 1990, an asbestos inspection is required. If asbestos is found, removal must be completed and a clearance certificate obtained before structural demolition begins.
- Council notification — In NSW, most demolitions require council notification or a Development Application (DA). Your demolition contractor or certifier handles this.
3. Physical demolition (2–5 days)
Once utilities are disconnected, asbestos is cleared and approvals are in place, the physical demolition is typically fast. A standard Sydney house knockdown takes:
- Small fibro or timber home: 1–2 days
- Average brick veneer home: 2–3 days
- Large double-brick home: 3–5 days
4. Debris removal and site clean-up (1–2 days)
After the structure is down, all debris is removed from site and disposed of legally. The site is levelled and a demolition certificate is issued. This typically adds 1–2 days.
Total Timeline Summary
- Fast-track project (no asbestos, simple structure): 3–4 weeks total
- Standard project: 4–6 weeks total
- Complex project (asbestos, double-brick, access issues): 6–10 weeks total
How to Speed Things Up
The biggest delay in most Sydney demolitions is utility disconnections. Start this process as early as possible — contact your electricity, gas and water providers as soon as you have a demolition date confirmed. Your demolition contractor can advise on the process.
