  • The main concern about an unlevel floor is why is it unlevel? If you can figure out the “why”, that will tell you if it’s easily fixable or if it will potentially get worse.

    How hard it is to investigate depends on how accessible the underside of the floor is. It’s going to be pretty hard to tell from the top side without ripping off the tile first.

    If the room has a crawlspace or basement underneath and you feel like playing detective, get a bubble level and go check the joists and beams in the vicinity. Work downhill until the slope stops. That will give you a general area of the source of the problem.

    There could be a variety of causes, some of which are obvious, some not as much.


  • Yikes! Don’t bother trying to patch it. That floor is a disaster and needs to be completely removed and reinstalled. As at least one other commenter mentioned, the tiles should be staggered and have room around the edges for expansion. The reason those popped up is because there are no gaps for expansion around the edge of the room. Also, they did a really sloppy mortar job. I’m not even sure they used the right mortar but it’s hard to tell from just the photos.












  • Part of the challenge is that most of the rainwater doesn’t originate from the exterior in the area where I’m working.

    When they poured the front porch (which is actually towards the rear of the house from the street since the house sits sideways on the lot), they didn’t backfill it correctly. As a result, there’s a nice little spot next to the foundation, under the front walkway, where water that gets through cracks in the walkway gets funneled downhill under the walkway and front porch, through the exterior wall, and into the corner where I’m digging.

    There’s a small hole in the wall on the other side of this crawlspace (see photo). When I first discovered it I looked in and could see the front porch slab above it. It’s big enough inside that if the hole were bigger I could probably crawl into it.

    Long term, the whole walkway needs to be ripped out, backfilled, and replaced. But that’s going to be $$$ so it will be a few years before I can do that.
