I have been dealing with this issue on a house I just sold. This is what I learned about home warranties. Most (if not all) do not cover pre-existing conditions. The warranty company will do everything in their power to prove that whatever piece of equipment breaks, it was due to a pre-existing condition. You may be able to take them to court and win because many times it was not due to a pre-existing condition, but how much is your time worth?
