I have a home owner that agreed via email to a fixed price contract for floor tile installation, refinishing of hardwood floors and the installation of the bathroom fixtures. Once the carpet was removed we discovered stains in the wood floors ( my contract excluded repair or replacement of any damaged wood flooring) I gave the home owner options to resolve this issue however she did not wish to spend anymore money and had me continue knowing the stains and bad condition of the wood would remain. The evening before I expected to finish the project I emailed an invoice for the contract amount and told her I would be complete around noon the following day. At 10:00 am the next day I received an email that stated I was completely out of line and that I must have made a mistake of at least $1000.00 at this point I knew I was going to have a problem and stopped work on the project until this could be resolved. We met at the project location once after I stopped work and at that time she told me she did not want me to complete the contract and we went discussed what needed to be completed and she said she would get back to me. I sent her a new invoice that reflected a credit of 4 hours which is what I had estimated it would take to complete the contract scope of work. She sent me an email that requested another meeting at the project site when I asked her the purpose of the meeting she listed the same things that we had discussed in the prior meeting plus made comments that were personal attacks toward me and requested how I came up with the figure I had come up with for the contract. I'm still hoping I can resolve this but I need to know what cost effective legal action I can take. Thank you in advance.
