Condensation issue
Hello Everyone, I am wondering if anyone has had this issue, and if so how can we fix it.
We bought an apartment in La Cala, had it renovated with new doors, window,s floors , etc and have now started furnishing. The flat was locked up from Oct to Jan and when we went over our flat was black , walls, ceilings . My husband thinks it is condensation. Can anyone give advice. If i left any windows open i could have a Cockroach infestation etc or burglary.
Has anyone else had these issues, and if so please can you give us advice on what to do.
Thank you so much in advance for any HELP. x
