My name is ***** ***** I am a NSW Solicitor. Thank you for your question, and will do my best to assist you with your question. Please understand I am very limited on what I can tell you and that you may have to get more detailed advice.
They are in breach of the contract but you have to look at what the contract says about delays. You cannot do anything without looking at the contract. If they are doing the work and it is progressing I would suggest you simply be patient.
The bills you are receiving again have to be in accordance with the contract. They should be set out what they have to be paid and at what stages. If there is nothing like that you have to discuss it with the builder.
Also if there is no contract I would be worried and you may have to consider taking this to the small business commissioner.
Here is some information.
I hope this makes sense and is of assistance If there is nothing further
thank you for using my services.
If I have missed anything, or you have any further questions please let me know
If there is anything else in the future please do not hesitate to ask.
Please do not forget to leave positive feedback.
