Mold grows in warm, damp areas where there is little to no circulation of air. Tiles and grout are susceptible to the formation of mold, especially in bathrooms, kitchens, and anywhere that supports the conditions we mentioned.

Grout in Damp Areas Is Susceptible to the Formation of Mold
Basements, laundry rooms, and even around a swimming pool are other areas that might see the growth of mold. Seeing mold form on your tile grout is not at all uncommon. This is because tiles are often used in wet areas, and the porous nature of much of the grout used for tiles makes it particularly susceptible to mold.

Mold causes problems, both cosmetic and from a health-related standpoint. Mold also causes issues with the integrity of your home. Proper grout sealing when the grout is first installed and follow-up grout maintenance is the best way to prevent issues with mold.

Choosing the Right Grout for Your Tiles

When you decide to have tiles installed, choosing the right grout can go a long way toward preventing mold from developing. Cement-based grout has a porous composition and is prone to mold growth, as well as the absorption of dirt and contaminants that can make your grout look unsightly.

Sealed and Epoxy Grout Are Less Susceptible to Mold Growth
Epoxy grout is a popular choice among many homeowners and contractors these days because it is much less susceptible to these issues. That's because epoxy grout isn't porous and does not absorb water and dirt.

That doesn't mean epoxy grout is the answer to all of your problems. It still needs to be properly maintained to avoid some of the concerns that come with age and exposure, but using epoxy grout in your tile installations can reduce maintenance costs.

Unfortunately, homeowners aren't always the ones who have the tiles in their homes installed. When you buy a home, the tile might already be in place, and you have no way of knowing what type of grout was used or if it was installed and sealed properly. Dirty or moldy grout can often be found in a home you purchase.

Many homeowners who view homes with porous, moldy grout might even pass on buying a home because the grout causes such an unsightly appearance. That's the reason it's important to have the grout cleaned and repaired before you attempt to sell a home.

Issues with Mold on Grout

We have already mentioned some of the issues that come with moldy grout:

Cosmetic - Moldy grout just makes your tiles and the rest of the room look bad. From an aesthetic standpoint, moldy grout looks dirty and detracts from the appearance of your tiles. Once mold has begun to grow on your tile grout, cleaning it is difficult. You can't simply wipe it away or apply tile cleaners to remove it.

Black Mold Poses a Threat to the Health of Your Family
Health Mold, especially black mold, can pose a threat to the health of your family. It can cause issues with breathing and can exacerbate asthma. Black mold is often "silent" because it can cause health issues without knowing it is the culprit.

Home Integrity Grout that has extensive mold growth is likely to be chipping and falling away, which can cause tile installations to begin falling apart. Moldy grout in bathrooms, particularly around very moist areas, will begin to fall apart first. This often leads to water damage behind walls.

How to Clean Moldy Grout

Proper grout sealing, as we've already mentioned, can help keep your grout in good shape for longer. Combined with regular cleaning, you can keep mold away from your grout. Keeping good ventilation and air circulation in rooms that are prone to moisture can also reduce the risk of mold on your grout.

Still, mold grows quickly in the right conditions and you might see it on your tiles despite all of the steps you take to prevent it. When this happens, professional grout cleaning, grout repair, and grout sealing might be necessary.
