Placing laminate on a crooked floor

Tone
by Tone
We are planning to put laminate on our dining room floor, which currently have an old vinyl, the ugliest you have ever seen! Haha...
Anyhow, at the center of the room the floor tilts downwards a little bit, like a crater. We haven't measured how much yet, but I would guess it is a few cm.
Anyone have any suggestions on what we can do to even it up? The easiest way is preferable, of course.

    Are you taking the ugly floor out?Do you have concrete or wood underneath?

    a sagging floor could indicate that you need to look at you foundations...and if it is the flooring already there then pull it up.

    First check to make sure there isn't foundation issues or floorboard stringer issues. If after addressing any structural issues, you find that the floor is still not level you will need to put down a leveling agent and then install new luan before installing the laminate.

    The best solution that I can come up with that is also the cheapest is to get some "self-leveling concrete" and pour it over the area of the floor where the dip is and be sure to feather it out until it's even around all the edges around it. This will level the floor out, however it will NOT fix whatever CAUSED the dip in the first place. There could be a problem with the sub-floor, such as a termite infestation that would cause that portion of the floor to need to be cut out and be replaced. There also could be a problem with the floor joists underneath the floor, such as a cracked or broken joist which would need to be braced or replaced in order to keep your floor from falling completely through. I would recommend that before you pour the concrete that you check the sub-floor and joists first to be on the safe side, because the last thing you or anyone wants is for you or anyone in your family to end up hurt and your home destroyed because you did not take this simple step first. Good luck to you!! :-)

      Crooked or lop-sided floors typically indicate an issue with the foundation. It is a very serious issue and one you have to have checked out by someone extremely skilled in this area (whether it's a friend, an acquaintance or a paid professional). Check credentials and hand over NO MONEY UNTIL THE JOB IS COMPLETE AND YOU HAVE HAD A CHANCE TO THOROUGHLY GO OVER THE WORK. I would not advise a DIY job... only if you have extensive experience working with faulty foundations. This is not a DIY job! I can say what I have because, we've been there. We bought a home (ROTTEN LEMON;-0), then later found out the home had been having issues, for years, and the owner who sold it to us was very aware of these issues. So... if I can help someone else from having to go through this nightmare, I'll certainly try! Hope all works out to your benefit:-)

    I don't think I'd use self-leveling concrete unless it's a concrete floor to begin with, and even then you would probably have to strip the vinyl to get good adhesion. Check out the other self-leveling options at your hardware store, though. There are some that are more akin to plaster, and I have used them over vinyl, especially when the covering is going to be laminate, which is very good at hiding imperfections.

    If there are no foundation issues you can use self-leveling stuff...it works just fine...used it when I put down laminate a few years ago. Just pulled it up to put down hardwood and did not have to do anything as the subfloor remained level where it was patched.

    Just make sure your vinyl has no abestos before removing it. The floor itself could have it, as well as the glue. If a corner of the vinyl sheet comes up and there is a thin, dry, fibrous, greyish ''underpad'', that could be asbestos too...Sometimes the only option other than abatement is to go over it...As long as it is not disturbed, it is usually considered safe.
