Most of us do not give much thought to our showers. With good reason, if properly installed you should have years of use without issue. However many people do not know that tiled showers actually need maintenance. Shower corners should be cleaned and recaulkd yearly. This will add to the life of shower and prevent costly repairs. You may ask why is this? Most point of failure usually start in the corner. It only take that one drop of water to work its way in to start a failure in a shower. If your handy, throw it on the calendar and set a few hrs aside to remove old caulking and add new. You can alway call a pro to handle as well! Happy showering!
