I am a contractor.
I have a contract with a customer for repairs and replacement of a buildings roofline.
We have a signed contract for the set prices and scope of work to be done.
The customer agreed to a deposit for the materials,and the work proceeded as normal,till winter ended the possibility of further roof work.
During the winter months the customer requested additional information about the materials already purchased(knowing that it was non-returnable)and questioned why it was purchased so early during the construction phase.(red flag)
Since this time they have asked for a portion of their deposit(including materials of a non-returnable status) to be returned ,and rejected the material from the supplier(who has housed it for many months now)
It has been 11 months since this began,and the customer has now finished the workmanship on the building by hiring another contractor to apply the roof.
What is the timeline for contract expiration in Illinois,and with the contract I have now,signed and accepted by the customer,where do they get the right to do a job without consulting me first?
