My client once she had seen the issues has requested that she be compensated for the replacement of the entire door frame and have the bathroom professionally re grouted and the joints re sealed.
So the home owner had wasted good money on a DIY repair that was not up to the required standard.
The same can be said for cracked tiling on a bathroom shower floor. The bathroom requires a full renovation to rectify the issue, costing between $8,000 to $20,000 depending on fixtures or alternatively you could call a bathroom restoration company to replace the damaged tiles, re grout and then paint the tiles to look the same. This type of restoration normally comes with a 7 year guarantee or 3 year transferable warranty if your selling the home and costs approx $3,000 for a full size bathroom.
