I have some water damagedfloorthat I have to replace. It has long
since dried out now. I had some estimates done, found only two people
who would do it and one was twice as expensive. Anyway I spent the
difference and the cheaper guy (who had great references) left the
country, so I'm stuck doing as much as possible by myself. I'm going
to at least tear out the oldfloorand then decide whether I want to
try putting in the new one or not.

Right now its a part tilefloorand part vinyl, under both of which is
OSB. The plywood subfloorand joists are both fine, I as told. *I've
already torn out part of the vinyl, and am starting to chip away at
the OSB boards that are obviously swollen beyond hope. Now for the
questions, since I've never done anything like this before.

How can I know which OSB absolutely must be replaced? Can I just
eyeball it? Some parts that got wet dont show any swelling; other
parts I dont remember whether they got wet or not because the damage
is old. I dont want to remove boards that are OK, and I dont want to
find out when I'm (or whoever) start to put down the vinyl that there
are still bad boards.

Other than that, what do I need to be aware of as I do this? I'm
worried I may accidentally damage the subfloor (though I cant imagine
how) or do some other expensive mistake. *There is very little mold.

I'm guessing I will have to remove a min of 5-6 OSB boards across two
rooms, but at worst it could be closer to 10.

Don't do half a job. Remove all the tile, lino andOSB together. Sinply
set an old skill saw for the thickness needed and cross hatch cuts to
make manageable pieces. *Start again with new materials as you will
not be capable to clean the old OSB enough to put a finishflooron
it.

Well I may have to replace the entire vinylfloorin the kitchen,
though that will be a major task. There are 3 very large banks of
cabinets, a sink and water heater that will have to come out. Ugh...

But I should be able to just replace part of the tiled dining room
OSB. It just has self adhesive tiles and most were replaced less than
2 years ago so new ones should match up pretty well.- Hide quoted text -

It sounds like the water heater might be an issue, but draining and
moving it is relatively easy.

As for banks of cabinets, unless you have evidence that the damage
extends under them, you can probably replace flooring andfloor
coverings up to the base of the units and use a trim to conceal the
edge. *Ideally all the old OSB would go - your comment about "little
mold" is telling. *Playing with possible mold has all sorts of nasty
consequences. *If you ever get inspected down the line and mold comes
up, that's a big black mark.

When I replaced flooring in our place after a large water damage
issue, I took out all the boards with any evidence of water contact,
then the boards adjacent to them. *I was "fortunate" in finding that
our old place had a tiny slope to thefloor, so moisture travel was
restricted. *In the vinylfloor area (kitchen), I took up everything,
put down new ply, and relaid the new vinylfloor. *In the rest, I was
fortunate to be using carpet, and underpadding can hide a multitude of
sins ;-)

But bottom line, don't let the idea of a smaller (or cheaper) job
prevent you from taking up anything that could even possibly be water
damaged or contain mold. *Just not worth it.

I'm finding it pretty easy to determine what got wet. Where the osb
got wet, it crumbles when I pry it up.

I have been finding small patches of mold/mildew in places where I
expected to, like along the wall. But everything is dry so I dont
foresee it sticking around.

I presume you don't have homeowner's insurance that would cover
this?

Regarding how much to replace, it's always going to be a judgement
call, unless you replace all of it. Given the consequences of
failure, I'd err on the side of taking out extra, as opposed to
not. Anything that looks at all suspicios or that you know was water
logged goes. We don;t know the percentages, but it may be best to
just replace it all in the areas that are being redone.
