I have a rental property in Wildwood ( Doo Wop Capital) New Jersey. It has an outside front porch appros. 7 ft x13 ft with bricks around the perimeter. It is elevated, with a crawl space underneath it. I ripped up the old outdoor carpeting and most of the old flagstone and mortar came up with it. It seems as though the mortar that held down the flagstone had deteriorated. What is left now if a 3"-4"solid concrete base.with bricks securely attached around the perimeter. The patio is against the house (brick). The depth of this area is between 1" to 1 3/4" I have asked numerous contractors what is the best way to fix this and I get different answers with prices ranging form $450 to $2,500.Recommendations included tile, fiberglass, stamped concrete and concrete.The concrete contractors say they need to chisel or jackhammer the concrete foundation to 3"-4", but my worry is that it may crack the foundation or house bricks. I was hoping to concrete and acid stain it. Thoughts??
