Cost to repair

[hokie27 0]

Hi, My pvc floor tiling in 3 bedrooms ( installed around 2 years ago) are gradually coming loose; adhesive used doesn't appear to be good. The ID company (SpireID) which did the reno work, is not reachable anymore; Would like to understand what would be cost to repair as well as some reference of who can do this work; room sizes are roughly 13 ft x 13 ft; Tiles themselves are in good shape; adding a picture to give ref to issue;
