OK this is going to sound strange...
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
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!
How wide are the cracks? hairline? pencil tip width? dime thickness?
What kind of fastener did they use to install the shutters to the
Are there any similar cracks in the wall outside?
My WAG would be thye used a pound in wedge anchor (I hate those things)
rather than a chemical (epoxy) anchor.
check for cracks outside & determine anchor type
here's another WAG
I'd fill the shower side cracks with a slow set epoxy & then remove the
shutters....maybe the crack will close when the anchor is removed and
the epoxy will fix the crack for good
if the cracks don't close....... wipe the epoxy out of the crack &
replace with a flexible chaulk when the epoxy residue is cured
are your blocks hollow or fully grouted?
