Black mold in villa: DIY bleach or professional help?« Back to Previous Page

We've lived in our villa in Al Barsha for two years and just noticed a bunch of black spots spreading on the wall behind our wardrobe. It’s gotten worse since the weather got more humid, and I'm worried it might be affecting our health. Is this something I can handle myself with bleach from the supermarket, or do I absolutely need to call a professional mold removal company, and what kind of costs should I expect for a room this size?
