No idea where Damp smell is coming from..... please Please help!!?

Question

OK.. hers the story...

Back in March, i noticed a very bad damp smell coming from the bedroom walk in robe.... we decided to get it investigated & then was horrified to see that the shower had a leaking pipe & all water has come down thru the wall cavity & under the carpet (over approx 8 mths) & alot of mold had developed!!.... SO..... it took us 3 months to get this all fixed.. fixing involved.... Fixing the leaking pipe, removing old carpet, knocking down walls where water damage was, get room professional cleaned by a mold restoration company, get new walls, paint new walls & replace new carpet & underlay!!

NOW... approx a month after all this was done & everything seemed fine... THE SMELL HAS COME BAK!! we have lifted the carpet & there is no dampness & no water leak etc... Where on earth could this smell be coming from... we have cut holes in the walls to see if any mold was left behind but there isnt any..... would anyone know what else we can do or what is happening??

Answer 1

There is likely a small hidden area they did not get completely clean.  The reason you smell it more now is probably a change in conditions, such as temperature, humidity, etc.  It would be a lot of work to go back in and try to find it.  I assume you got some sort of guarantee with the original job.  If it does cover something like this, contact the contractor that did the original work.  They will have to fix it.
