If the landlord has a duty to repair such problems under your lease, and if you have followed the instructions in your lease for providing written notice to your landlord, and he has nonetheless failed to repair the problem, you could pay to have the problem fixed yourself, then reduce your next rent payment(s) by the cost of having the problem fixed. It's also possible that you could also recover back rent and have your lease terminated early. Without seeing your lease and knowing what notice you've provided, it's difficult to be more specific. I hope this helps. If it does, please indicate that it was helpful. Take care.
