Why is there mold in my shower?
If you have a tile shower pan, then likely you have split hairs trying to battle mold in the pan, and on the curb of the shower. In order for mold to grow, it requires a high level of constant moisture. Even if you try using mold killers, like Clorox or Tilex, the mold keeps returning—and we know how frustrating this can be. But, there is hope for your situation. Lets get into the reason your mold keeps coming back.
What is the most common reason for mold in the shower?
From our experience of cleaning and restoring showers, we find the most common reason points to the shower drain weep holes. Your naked eye cannot see it, but there is actually a puddle of water trapped below the tile, and it has no where to go. To explain-if you have a tile floor in your shower, then you have a weep style drain. That means that any water that gets below the tile should migrate to the drain if the weep system is working properly. This is where we run into a problem. We find that about 90% of the weep drains are clogged when the builder hot mopped the shower with tar. This means that its possible that your shower has never drained properly. What also contributes to clogged weep drains is bar soap residue and hard water buildup adding to a mineral clog. To lookout for other signs of a clogged weep drain—-look at the floor of your shower. If you see cracks in your tile, or cracks in the grout line, or white minerals/calcium migrating up through the tile or grout, and lastly, wall damage on the outside of the shower curb. These are all signs of a weep drain problem.

weep hole cleaning service that will open up your drain so that it can function properly. This will allow your shower to drain the way it was designed to, and we are confident that your shower mold problem will significantly improve.
Can’t I just continue to treat my shower with bleach?
Bleach is an excellent disinfectant and is great for spot treating some problem areas in your shower. However, bleach is a powerful oxidizer and overtime will destroy your grout. We find that with constant use of bleach in your shower, after a short period of time, you are in need of a shower regrout. If your goal is to get the most life out of your grout, not to mention grout sealants, we recommend avoiding heavy use of bleach.
