Spotlight Product


Concrobium Mold Control and Concrobium Mold Stain Remover... 






 This is what David uses for mold in natural stone showers.  Concrobium Mold Control will not etch natural stone.  Yes that's right, no etching.  Concrobium Mold Control is a dual purpose antimicrobial that remediates mold spores and prevents mold growth without harmful chemicals.  David has spent almost 2 years trying to find a great mold and mildew cleaner and now he is sharing it with you.  Just spray it on and let it dry.  When it's dry that's when it does its job with very little environmental impact.  


The Concrobium Mold Stain Remover is a very serious cleaner for mold.  This one packs a punch (smell).  And the shelf life for this product once mixed is 20 only minutes.  This unique solution quickly and effectively removes the toughest stains without scrubbing.

Weep Holes: 

I know, what the heck is a weep hole?  Weep holes are a vital part of your shower drain assembly.  Typically, there are 3 such holes in the upper portion of the drain assembly, these holes are spaced evenly around the drain.  The weep holes are small holes that connect to the main drain, allowing water that enters them to feed evenly into the drain pipe.  If your shower drain is all one piece of the shower pan, you might also have weep holes in the pan itself.  The problem is that hair, body oils, soap residue, and hard water can clog these little holes (especially hair conditioner and white bar soaps) causing water to stay in the pan.  If you find that the lower shower walls and floors are darker then the rest of the stone this may be due to clogged weep holes.  And yes, this is fixable.  I bring this up because we are doing a large amount of repairs every week and no one seems to be able to identify the weep hole system.
