When your once-dazzling shower is setting out to look downright depressing and therefore the clean, sharp lines that after framed engaging covering are setting out to look dingy and worn it's time for grout repair.

One of the most common calls we receive here in my home repair business are for bathroom shower tile repairs. Failed bathroom shower tile is an expensive deal.
