We bought a house and I asked the owner when the last time the chimney was cleaned... The look on his face... you'd think I asked him when the last time he flew to the moon was or something... I'm amazed people don't understand that you have to clean your chimney or clear your driers exhaust line. Took me $20 at the hardware store (with extra 8' extension) and 20 min.... Maybe they need to have a test for home ownership too!
