Hello All, I have a really old house and the flooring slopes in a few places and hired a handyman to help me put in pergo outlast flooring. First he told me that we just needed a few bags of leveler and then that would level out the uneven spots and then we could put in the flooring. The previous owner had tiles down but they cracked and looked horrible. Like a dummy i paid him and didnt ask how long it would take. It seemed like a quick thing. Well he comes over once every few days to put down more leveler. About 13 bags later which is about $550 worth of this leveler junk hes probably ... maybe? half done? He went to home depot with me and i gave him a hard time because he changes his mind on big items which require delivery. And neither him or i have a truck. So he mentioned hardy backerboard. I just said whatever you think is best. Well because I asked him if it was possible to put it in his van instead of delivering it (another $60 fee if homedepot delivers it), he figured he would screw me i think. He had me buy about $500 worth of this floor leveler and he basically is coating my whole upper floor (200 sq ft) with leveler! And to make matters worse he only does one small patch at a time which has now taken months. He told me the other night that because I gave him a hard time he decided to go this route instead of using qwikset and hardy backer board to even the floors. You want fast or good he asks me. I said i just want a floor. Apparently the good version would require about 10-20 more bags of this expensive floor leveler his way. Now he says maybe we should switch streams and use hardyboard. It will be hollow when you walk on it but its quick. So now $500 in materials and his labor later im going broke and could use a friend to help me sort this mess out. Should I keep pouring expensive leveler over these OSB floorboards and wait for months while he takes his time getting the floors leveled off? Or should I bend and buy this qwikset and hardyboard and lay that on top of the half leveled mess he has created and just fill in the low spots with quickset? Please help? :help: im going broke on this. Thank you in advance!!

I live in South Florida and wanted to get Impact Windows installed, but the front of my house (built circa 1958) was settling so I had to address that issue first. House is stucco covered concrete block construction so I had a contractor come in who attached 7 piers to the foundation, drove piles down until they hit bedrock, and then raised the house to stabilize it. However, I have a floating slab and when the foundation went up the floor didn't move, so I now have a major gap ranging from 1/2" to 1-1/2" between the interior walls and floor slab. Now that the impact windows have been installed it's time to install new flooring, but I need to address the floor issue first and have some questions: 1. I'm thinking I should first fill the gap with Great Stuff or something similar to prevent the self-leveling floor mixture from simply flowing out under foundation. Yes/No? 2. Can I put something down as a "filler," like plywood or backer board, at the gap's largest points? It will still get covered with at least a half-inch of floor leveler, if not more. 3. I'm also concerned that, if I can't use a filler of some sort, considering how much leveling mixture I'll have to use, the additional weight will just cause the slab to settle even more. Comments and/or advice from anyone with floor leveling experience would be most welcome. Thanks in advance.
