Hi there! I completed work on a home in la jolla Ca for inside and out window cleaning. The home owner is now reporting that there are scratches on 6 Panes of glass and is refusing to pay. The windows in question were cleaned the same way every other window in the house was cleaned and the home owner was informed of the equipment we would be using to clean the windows. I told the home owner that he should contact the window installers because it looks like the window was installed backwards and the low e coating is on the outside. The home owner is insisting on running my insurance even though I explained to him that the damage was not caused by faulty workmanship. I already filed a 20 day preliminary notice for a lien but I want to know if he would have a case if he chose to take me to court for damages and what I should do to protect my company.
