The front of our old house has a large covered porch. The steps in front of the porch are about ten feet wide and have a large decorative curved & sloped cement edge on either side. A couple of the steps have front edges that are crumbling and have been patched, but are now re-crumbling. I'd love to cover them with brick pavers. Is this feasible? Are there any special hints? Should I attempt it or hire someone?
