What should I do about me and my dads relationship?

My mom died two years ago when I was 10. Every since then, me, my brother and my dad have had a very un-organized life. Our house is always cluttery and its not finished. My dads always working on it but never seems to make any progress or get anything done. We are always fighting about keeping the house clean and its always him leaving around tools and not cleaning up after himself. I am constantly trying to clean but i cant keep up on it ALL the time because i am still a kid and i shouldn't have this much responsibility. I don't like to have people over without it being clean so whenever i want my friends over i have to tidy so i don't feel embarrassed. I always find myself trying to rebel against him and avoid talking to him as much as possible. I am always locked in my room and keep myself away from the rest of the family because to tell you the truth, i don't like him at all. Maybe its because of him not caring about the house or maybe not but he doesn't seem to understand its hard on me having to live without a mother, with all boys and no one to talk to about the house. He doesn't make me and my brother do any chores so my brother doesn't do anything. My brothers 10 and doesn't care at all about the situation. Whenever i do bring it up it always end up in a big fight and we get even more fed up with each other. Our relationship is horrible and i don't know what to do.
