We were bamboozled which company to use and trust to seal our shower. A big company came out and said it needed to be re-tiled (at an enormous cost). We decided to get Water Leak King to also have a look. Their technician ran a series of checks and advised the tiles were all solid and that the problem was the split junctions not the tiling. We gave them the go ahead and the shower not only looks great but not a drop of water leaking since. Best few hundred dollars we’ve ever spent. Thank you and we highly recommend Water Leak King.
