Mold: Behind baseboard and Under the carpet
 

Folks:

We found some dry black spots after we removed a portion of a base board and underneath the carpet.

The issue was that during rains there was water use to come and kept this area wet. Now I sealed the hold for the water but i now i see mold spots. I cleaned up with a bleach but would like to know if i should replace the floor boards or let it dry and put the carpet back. It is on the second floor near the deck door.

Bleach is only really good on solid surfaces like tile. I'm not sure what you should do with the floor. The wall, if it looks like the drywall was wet I would remove the bottom 3 or 4 inches and inspect the bottom of the cavity and the insulation and allow things to dry out. The foam underlay should be tossed. To be on the safe side I would replace that peice of subfloor and you would really be able to see if the dammage is deeper.

Actually dry wall is dry not. I was dry when we removed the base board and mold was dry black. I can call someone for the subfloor and dry wall if this is the recommendation.

That is what I think you should do. The wet drywall has to go ASAP.

Let me guess, someone built the deck even with the threshold. That's got to be the number # reason for wall and subfloor rot.
Code calls for at least A 4" Drop below the threshold for just this reason.
Just adding caulking is just not going to be a long time fix on this one.
In most cases the ledger board was not flashed right, there was no sill pan under the door, flashing done wrong around the doorway.
If all this is not corrected asap it can get real expencive latter on.

Hi: I agree that there is no 4" drop on this one!! Floor pan outside the entry and the floor inside are at the same level. It would be helpful if you can give me some recommendation on how to prevent it from future happening. Right now i put silicon coating outside at the junction of floor pan and planning to replace floor boards. The area gets good sun light.

I got it let me see where i can find it. I am in San Diego, California.

BTW one more question for you guys!!

1. Dry wall is not wet anyone. I took the layer off the dry wall and its all clean and clear. So wondering if i need to cut a piece in drywall and replace it.
2. Do you guys recommend replacing the floor boards or do the mold test and then if positive then replace the boards.
3. Any suggestions whether insurance will cover this or not?

If the water was coming under the door, it was just as easy to come under that wall, so I would remove some drywall at the bottom so you can inspect the bottom plate. The floor looks like Adventech, you could call them and see what they say.
Insureance may cover part of it but they only cover the dammage not the cause, so you would still have to pay for re and re the door. Then you have to look at your decuctable and what happens to your premium next year.
