Why Does my Bathroom Grout Crack?

When it comes to your bathroom’s appearance, you mostly pay attention to the cleanliness of your drains and matching towels. However, if you're someone that pays attention to the little details in life, you may start to notice that the grout lines in your bathroom crack over time. But since you're not exactly inflicting wear on your grout, you may be confused as to why it cracks in the first place.

Why Does my Bathroom Grout Crack?

Home Shifting

As you learned in third grade science class, the plates that our continents sit on are constantly shifting and sliding. Because of that, our homes do the same; albeit very slightly. Now knowing this, your grout lines can become loose as they are pulled from their original position.

Too Much Moisture

When grout is originally mixed, water or a polymer additive is included in the solution. While this moisture is designed to evaporate, if too much evaporation occurs, your grout can be left with miniature holes — not necessarily visible to the human eye. Eventually, it won’t be as strong over time, which can lead to the initial cracking.

Poor Tile Installation

In order to have a secure hold, tiles need to be attached to your bathroom wall with the right amount of adhesive. If they’re not, then it will be up to the grout to hold the tile to the wall. Now, as you may have guessed, that added (unnecessary) stress can cause the grout to crack under pressure.

While some grout cracks are easy to fix, others aren’t. In order to ensure you don’t experience the grout issues, it’s essential to hire only the best plumbers for all your bathroom needs. In the greater Pittsburgh metro area, trust the plumbing experts at Wahl Family Heating, Cooling, and Plumbing!
