We've got a small leak in our ceiling, and thankfully the weather has been fairly dry ever since discovering the noticeable water stains up above. The sloth-like response from our landlord is going to get a swift kick in the butt when we call the housing department, who has already noted the need for repairs. One worry is that mold might take hold, and this seems like a growing worry in homes these days. Toxic mold has been shown to cause a multitude of health detrimental conditions, including the worst of them all, death.
Of course, some people will take advantage by preying on this fear. KNBC investigators put some mold removal companies to the test by wiping a bit of black eye shadow on the bathroom wall to see what these "specialists" would report back. You might want to take a look before investing in such a service (if your room looks like the photo above, one can be assured you need some professional help).
