caulking and preventing mold

the easiest way to prevent mold is to keep water away from any surface that can retain water or moisture
the simple way is to caulk, but what caulks go where ther are so many to choose from acrylic caulks are the most common and do have silcone in them but if you are caulking around a tub you would want to use 100% silicone your painter would charge an average price of 75 to 150 to caulk your tub but some contractors would throw that in while they are painting your home, dont forget to ask if they want your business and they are already painting your house the would be more than happy to do this
