For large renovation, refurbishment and installation projects an estimator or tradesman will scope the requirements before you incur any cost. An estimator or tradesman will come to your property discuss the requirements, provide a detailed scope of work and a fixed price quote to get it done.
The cost to complete work that has been scoped will not change unless the scope of work changes. Even if additional labour, parts or materials are needed to complete the work than originally planned, the cost will remain the same as provided in the quote.
Note: If a tradesmen has been booked to attend a property as ‘Time on site’ to carry out a job, and is then required to provide a scope of work, the time taken to investigate, write the scope and quote will be charged.
