Complex and Larger Jobs

For complex and larger jobs, we take the time to provide you with a thorough, itemised quote. Under NSW law, a contract is required for all jobs over $5000. For the following types of jobs, we will attend your property or site and provide a detailed quote before you agree to the work before going ahead:


Minimum hourly charge depends on day and time. The standard rate is based on 2 hours on weekdays. For any work longer, the price is based on the number of hours taken to complete the job.

The minimum hourly charge after-hours and on weekends is due to additional travel costs, penalty rates and minimum shift times.

Any unforeseen or hidden damages uncovered during the work may result in a variation to the original quote. This will be clearly communicated for approval before any further work is undertaken.
