Any ideas on what may have caused the cracking in the stone veneer on this home? The veneer appears to have been installed over brownstone - a popular material here in the city in the mid 1800’s through early 1900’s. The brownstone itself is has a tendency to decay and there was evidence of decay/scaling on some of the exposed brownstone.
I’m thinking the stone veneer was installed to cover the decaying brownstone instead of repairing or refinishing the original stone. Could the decaying brownstone also caused the veneer to loosen, crack and fall off or is there something else?
