Bathrooms are prime real estate for mold spores—bathrooms are often very humid, poorly ventilated, and susceptible to condensation or puddling water. All of these conditions make it the perfect location for mold spores to grow and thrive. Since bathroom mold is so common, many homeowners simply ignore it aside from periodically cleaning it. However, this is a mistake—mold that spreads to a porous surface in your bathroom is often nearly impossible for a homeowner to control, and the mold can spread further from there into adjacent rooms in your home. If you have mold in any of these three areas in your bathroom, you should call a professional mold removal company to control the mold and prevent it from spreading.
Mold that grows on your shower tile or on your bathtub is simple to remove—you can often simply spray vinegar on the surface and let it sit for a few minutes in order to kill the mold with minimum hassle. However, when mold spreads to a porous surface such as drywall, it becomes much harder to remove. The reason behind this is that mold spreads its roots deeply into any porous surface it begins to grow on. Its roots allow the mold to simply regenerate once you've killed the surface layer.
If you have mold growing on the drywall in your bathroom, whether it's one of the walls or on your ceiling, you should call a mold remediation professional in order to remove the mold. Fully removing mold from drywall is extremely difficult due to the presence of mold roots—typically, you need to cut the affected section of drywall out of the wall and carefully remove it from the home. This needs to be done by a professional in order to prevent spreading the mold spores further throughout your home.
2. Baseboards or Flooring
It's common for bathrooms to develop mold on the baseboards or on the floor. A leaking toilet, a shower curtain that doesn't close all the way, or members of your family who leave wet towels on the floor can all cause the floor to quickly become wet, providing a perfect surface for mold spores to thrive on.
Mold on your baseboards or on your floor needs to be handled by a mold remediation professional. When water seeps into the gap between your flooring and the wall, you can end up with mold growing underneath your flooring at the edges. This makes mold very difficult for a homeowner to remove on his or her own. From there, mold may be able to spread to adjacent rooms—if your bathroom is on the second floor, mold can begin to grow above your ceiling on the first floor, quickly resulting in a mold infestation that's out of control. It's important to call a mold remediation professional right away in order to control the mold and prevent its spread.
3. Shower Grout
When mold grows in your shower grout, you may have to have it resealed. Grout is another type of porous surface that mold will spread its roots into. There are a few products on the market that you can spray onto porous surfaces to prevent mold from regrowing—these typically contain either massive amounts of salt or mold-killing chemicals that stop the mold from regenerating from its roots once you've killed the surface layer. Unfortunately, you'll wash these products off of your grout every time you take a shower. Once mold roots get into your shower grout, it can be very difficult to stop it from regrowing unless you strip and reseal the grout.
To sum it up, you need to hire a mold remediation professional once mold in your bathroom begins to spread to porous surfaces. Mold becomes much harder for a homeowner to control effectively once it puts down its roots into a surface. If your bathroom has mold on the drywall, the floor, the baseboards, or the shower grout, it's time to call a professional to prevent the mold from spreading further throughout your home.
