I offer solutions for loose tiles, cracked tiles, shower and bathtub tile work. Often times the solution is to completely remove a failed installation and begin with the proper substrate. Unfortunately, many Builders and General Contractors lack the specific skillset to warrant a sincere assembly. If purchasing a home and the tile seems questionable, negotiate an allowance for renovation of that area. I will often meet with Real Estate Agents (for a fee) to photo document visible areas of concern. Demand an experienced TILESETTER.
