Last week I had someone here to install accordian shutters on my windows and doors. The house is a single story concrete block stucco structure.
One of the windows is a bathroom window. Inside is a tiled shower from floor to ceiling.
After the shutter installation, I did not notice anything. Now three days later, a crack across the wall tiles begin to develop below the window (about an inch below the window sill - horizontally). Along one edge is also a vertical crack from bottom of window to about a foot above the floor.
I have a feeling these cracks were from them installing the shutters...is it possible? Could they have drilled or used heavy duty tools to install the shutters that might have damaged tiles on the other side of the concrete block wall? If I have to retile that wall I have to redo the entire shower and shower pan!
