Laying flagstone over existing concrete patio-need to expand patio?
(Dallas ,Texas, usa)
I have 2 contractors telling me different things. I have an exsisting 9 x 22 concrete patio in good shape. We want to overlay it w/ flagstone and expand it to about 12 X 25.
Contractor 1: says he needs to tear out existing patio and pour a whole new patio or else the flagstone will not lay right and I will end up w/ cracks in few years. (very expensive) He is actually pushing Belgard pavers if I am not interested in tearing out the exsisting patio.
Contractor 2: says he does not need to tear out the old patio. He recommends extending the patio by pouring additional concrete and than just lay the flagstone over the old and new area of the patio. (less expensive)
We are on a budget. We could afford to expand but not a tear out. However, I do not want to be pennywise and dollar foolish. I am considering the pavers but I really prefer the look of flagstone.
Other info.: I am in North Texas and we would be using OK flagstone. Please advise
