I originally called BathFitter to fix a problem pertaining to water under the bathtub liner. The cause of the water was determined to be improper caulking around the tub-to-wall joint. A plumber was called to replace the caulk, and remove the water. This was completed at a cost of $500 to me. Although the water was removed, 2 more problems soon arose: 1. Within less than a year mold and mildew started to form along the caulk joint. The mildew was forming in areas where the caulk joint failed and water started to get underneath. It seems like the plumber did not properly clean the joint to achieve adhesion, and/or used the incorrect caulk due to it's poor performance. 2. The larger problem was discovered when I removed the mouldy caulking, to replace it myself this time. When inspecting the joint up close, I can see the tub and wall panels were installed backwards. In other words the wall panels did not overlap the tub in a "shingle" fashion. Any water that gets in the joint is led directly behind the liner. I'm concerned about moisture behind the wall panels and tub liner. When incorrect installation of products has the potential to lead to health concerns and airborne mould, the company should be especially conscious of sound installation techniques, training, and 3rd party "plumbers" who are contracted to do repairs. The workmanship was irresponsible. The "plumber" replacing the caulking should have notified someone of the incorrect installation.
