Showers will be in self-contained “insets” or they will be in areas which have been “water-proofed” with tile or other materials. Be alert for signs of leaking or others problems. Be sure the grouting and the sealants and intact and in good shape. If you see problems that concern you, call the Professionals at PuroClean. Every situation is different! For the best, specific advice, please call your local PuroClean as soon as you have a concern.
