moldy sink
Posted by: Fritz

the underside of a bar sink has some mold.
Cleaned that, but I think the humidity is rising from the basement directly below and the back wall shown here (that may have been left as balloon framed without a sill plate).
Access now would be difficult at best.
The sink drain isn't leaking near as I can tell.

Should this be stuffed with glass or might that exacerbate (my $2 word of the day) the problem?
If not, a better solution?

There's no mold on the unpainted sheetrock or any other surfaces, just the sink insulation and just the sink insulation at the bottom of the sink ?

Do you leave ice in the sink to melt and drain away often ?

correct
nope, ice gets dumped into houseplants.

and the mold smells as soon as you open the cab door.
There is a pull out trash/recycle container under the sink.
I wiped all it's bits, in/out and 9 ways til sunday.
The recycle bag gets changed every week. The trash, twice a week.

There is diatomaceous earth on the deck of the cab as we were getting cave crickets coming up.

When I've had a leak under a sink the unpainted sheetrock got moldy and ( for some reason, maybe temp diff ) the back side of the cabinet door(s).

Just the bottom part of the sink's insulation getting moldy like that seems odd.

Ice left in the sink causing a condensate problem under the insulation could do that.

Was that sink sitting in a puddle of water before it was installed maybe ?

I'd be tempted to paint the insulation or cut the moldy part off.

nope, right out of a box. weird. Maybe I'll hack off the moldy bit, seeing how the same bit fell off the main sink. It's a sound muffle, but on that little sink ........

cut a nice square hole in the side of the cabinet or door..scew a vent cover over it. Also..where the drain goes into the wall...in my house that's a fire chase..seal it, get some mesh tape and some durabond and mud it or something..your basement humidity will also be mitigated unless there's more airways we dont see.

Your issue here is fairly minor based on those photos..i've seen some really scary undercounter junk goin on. this aint nothin'..might just be a tiny maintenance point if you cant get it to stop..clean it when you reach for the whiskey bottle you've got stashed in there...should amount to about 10-15 cleanings per day.

It's dark in there.

What about putting something like this in the cabinet?

How big is that scrap of drywall that's screwed in there?

Honestly, i'd prob look at it and say 'mud"..but then I'd find a scrap of drywall, cut it to size, and then make a few measurements to locate a snug hole for that pipe (sexy, i know) and then find a jar close to the size of the pipe..trace a circle where you locate the hole and put a new piece of d-wall in there..then calk around the pipe and put a hinged escuctcthing on it..then id take a bump off that bottle of wehiskey you got stashed in that cubbie. It'll look so nice that when you walk away? You'll be lactating ten feet, frozen rope.

reading like you may have already. winking smiley

if I find a price of drywall around, then maybe. But mesh and mud is an easy enough removal if I ever need to.

Do you think you could have any water leaking around the drain in the sink? I would check the seal of the plumber's putty around the drain to see if a small amount of water water might be getting out there and settling down on that insulation at the bottom and causing the mold. I think I would cut off that bad insulation, neatly, and throw it out.

Since the mold is confined to the sink, I think the issue is with the sink and not that hole.

@rgG: checked and re-checked, but I'll still do again as that was my 1st suspicion. I was thinking cutting off the insulation as it would seem to make little difference.
The basement which is just below that sink, is very humid in warm weather. Which is why I was looking at the hole after not finding any obvious moisture under.

I would think if it was related to the basement, that you would have mold on more surfaces than just the insulation, but who knows.
I would definitely cut that bottom part of the insulation off, since you really don’t need it. My curiosity wouldn’t let me leave it there without knowing what was going on underneath. grinning smiley

Lol. My cat has no curiosity at all, save what’s for dinner.
