Over 60% of all claddings have moisture problems that damage the home.
It is much easier to test EIFS for moisture than any other cladding, therefore a lot more data is available. If other claddings were easier to test, the failure rates would be likely to be much higher than shown on the graph above.
Moisture diffusion in brick clad homes is very common and probably happens, to some degree, in almost all brick faced homes.
Hardcoat stucco homes have almost exactly the same risk potential as EIFS…and it is typically more expensive to fix.
