very uncooperative to work with, altered materials requested, did not install product to manufactures specifications. In written contract to build deck steps to code, but stated I told them it was not neccessary. Difference from top step and bottom step was well over an inch, does this make sense, we are middle age and can trip on this very easily. Had over $3000.00 in materials and labor before I stopped them, and will have to redo most everything.
