Hello! We are new parents and just bought our first home. We have noticed this spring that there are brick pieces falling off from the top-most two feet of the chimney. They are "slices" of brick that average 2-3 inches and some small chips. How would you suggest that we do? We are parents of small triplets with not much time on our hands or relatives available, and don't want to get ripped off. How do we find quality labor?
