Mold leaves Bradford Town Hall unusable. My opinion is that this was not a new problem that developed in the building overnight. When buildings get wet, or roofs are neglected, small leaks seen in the basement, all these can lead to worse things, like mold. Mold is dangerous and can be nasty. Even in perfectly healthy people, mold can cause breathing difficulties, head aches and various other sickness.
If you already have asthma or other breathing difficulties, watch out. Sometimes you can find the mold quickly, but sometimes it is hidden in cracks and crevices, like the attic or basement of an apartment. Most of the time the symptoms go away as soon as the mold is fixed, but sometimes it can also cause long term health issues.
