I am very new at all of this, so please bear with me. I have lived in my home for 7 years now, it was built in 1958 and everything has been fine until about 8 months ago. I noticed in my bathroom that there was a "small" gap between my baseboard and my floor, my brother said that my support beams needed "extra support" but did nothing to help. Now 8 months later I have about a 3 inch gap in my bathroom; my floor is slanted in there as well as coming down my hallway and living room there is about 1/2 inch gap between baseboard and flooring. My questions: 1) Is it now to late to add the extra support? 2) What do I need to get (I have heard of "floor Jacks")? 3) Where do I need to go to get what I need with out being taken? I am single and have no help in this matter, so any advice would be greatly appreciated. The house is 960 sq ft, one floor ranch style home.
