There was a small leak over a long period of time under my kitchen sink. This
past weekend, I went under the house for other reasons. Out of curiosity, I
looked at the floor underneath the sink. It is all black from the leak.
Presumably the black discoloration is mold or mildew. The leak has been fixed.
We sprayed bleach in all of the areas we could reach to kill any mold.
The kitchen cabinet floors are not removable, as best as I can tell. Is there an
alternative to removing the cabinet and replacing the subfloor? I'd have to hire
someone to do it as that's beyond my limited skill set.
Because I want to be able to sell the house? Seriously, is it sufficient to just
kill the mold/mildew and move on? Under no circumstances do I want a health
hazard for my family or for a subsequent owner of the house, nor do I want to
have to tear out the kitchen if and when we decide to sell.
There is a very good chance of having black mold under the cabinet. The
only DIY I can think of is to cut out the bottom of the cabinet leaving
a couple inches all around. Kill, clean the mold/floor below, then cut
a piece of thin plywood and set it on top of the few inches you left
when you cut out the old bottom. Actually, if it was me I'd do that
exact same thing.
Mildew has been around forever and spores are EVERYWHERE. It grows in
damp places. If you are worried, drill a couple of holes in the bottom
of the cabinet, spray in some 10% bleach/water and then forget about it.
Seriously, someday the place will be sold by you or whoever after you go
to the big duct tape factory in the sky. A home inspector will point it
out to the buyer, may say it appears to be inactive but the buyer should
get an opinion from a certified mold inspector. Buyer may try to put that
expense on the seller. My understanding is those are not just a couple of
hundred bucks but I really don't know firsthand.
The correct answer is: YES, NO, ABSOLUTELY, DEFINITELY, MAYBE, AND I DON'T
We cannot give you accurate advice because laws in your state (all bets off
in California) as to disclosure and mold remediation and such things may not
be accurate where YOU live. Consult a local expert, and go from there. You
can get an expert free opinion and inspection from a licensed contractor.
What's the downside to that?
If you DO sell, and there is mold remediation needed, you have a few ways to
go. One, don't say anything and hope they don't catch it; don't say
anything, and if they do catch it, they will rake you over the coals;
disclose it, and have them knock a chunk off the price; have it fixed now.
Get some local professional opinions. You'll get lots of free opinions here
and they are worth ten times the price. And they may end up costing you big
re: "Because I want to be able to sell the house?"
There was just an article about this very subject in the Home section
of my local paper.
The suggestion for "black spots on the roof rafters after the mold had
been bleached" was to document the steps taken to remediate the mold,
have the attic inspected by a mold remediation company and save the
documents for any perspective buyers to review.
However, even if you gave this documentation to me, I'd still have my
own inspector "certify" the absense of mold.
If you decide to go the inspection route at this time, it would
probably more for *your* piece of mind than any perspective buyer's.
