Our former landlord came to the property 4 times without notice, several occasions landscapers/workers came over without notice. As well,the landlord visited/inspected/worked 35 documented times in one year with notice. The windows were not in good repair, they shook with the wind, the house would not heat, wind howled through the house, I have photographs of the 3" space between the window and the window frame. We asked the landlord, in writing to repair the windows and doors, she denied our request, and gave us some weather stripping (HA!) Our heating bills were $600.00/month. When we moved out, upon a lawyers suggestion, we did not pay to refill the oil (500$ in oil)citing these numerous offenses (visits without notice, habitability, quiet enjoyment. She is suing us for the oil. Help?
