Hello, Here is a series of events. Hired first contractor (Will) to rehab a house. First contractor did not finish job, payment plan with us, he could not finish the job and still owes us roughly 16,000. First contractor hired sub-contractor (Ron) to do the HVAC, however, he did not pay the sub contractor. We paid the first GC 12,000 to pay for the HVAC but never gave him (RON) the money. We found the sub-contractor and decided he could be the general contractor to finish the job. However, he was not working to our standards and was let go. Now, he wants 6000 grand for the equipment, HVAC. Am i Liable as an owner of the house to pay the 6000 grand back for the materials bought with the first GC? I
