Home builder uses this sub contractor, not our choice. Installation appeared to be satisfactory upon acceptance of the house. The kitchen island ended up warping somehow and both seams in the countertop split and shifted. The two seams were repaired in January 2019 and the island countertop was replaced in May 2019. The one seam split and shifted again in October of 2019, and the other seam repair area is sub par, as the seam is clearly evident and felt from the surface. Have been in an email war since then to get the repair made with too many empty promises of a repair date. In my situation, they just don’t seem to stand by their work.
