Have you ever walked into a kitchen or bathroom and noticed that the tile suddenly had a crack? You’re not alone – as it turns out, cracks in tiling can be common. But why do tiles suddenly develop cracks, even when they look excellent at first glance? 

In this blog post, we’ll discuss what may cause tile to suddenly crack and how to prevent it from happening so you can keep areas of your home looking beautiful for years to come! 

Always rely on professional and reputable tilers in North West London if you don’t want your tiles to crack unexpectedly. 

Cracked Substrate 

Tiles can be a great addition to any home, but sometimes they’ll come with a crack if there have been issues with the substrate underneath them. Homeowners must check for any signs of cracks in the substrate before installing new tiles, as this can lead to them cracking later down the line.  

Not only is this unsightly, but it also takes time and effort to replace the tiles and fix them correctly.  

Prevention is always better than cure when tiling, so make sure you scrutinize your substrate beforehand and fix any minor issues quickly! 

Heavy Loads 

We have all been there: you place a heavy piece of furniture on top of the tile in your house, and before you know it, a large crack appears. Many people do not realize that tiles can only support so much weight.  

Depending on the type of tile, even seemingly sturdy items such as couches and dressers can cause them to crack if they are placed in an area with too much pressure.  

To prevent this from happening in the future, keep an eye on where and how you put heavy items in your home – tile floors are great for adding beauty and resiliency to any room. However, taking precautions is still essential when placing large objects on them. 

Low-Quality Tiles 

Are your tiles looking a little worse for wear? Don’t be too disheartened – it may simply be that you installed low-quality tiles. Low-grade materials can lead to chips, cracks, and general wear and tear much sooner than high-grade materials, so getting the good stuff is vital! 

If you have noticed any changes in the stability of your tiles over time, it could be because they cannot handle stresses or thermal changes adequately. Stone tiles, in particular, need extra care and attention from their owners – proper maintenance, such as regular cleaning and sealing, can help keep these tiles looking great for longer.  

That said, don’t be afraid to replace your less resilient tiles with higher-quality counterparts to avoid future cracks and chips. 


Why do tiles suddenly crack? Movement in the foundation, settlement, or heaving of the ground can stress tile floors and walls, causing them to break. 

In some cases, thermal expansion from temperature changes can cause ceramic tiles to develop cracks. 

If your home has developed tile cracks, it is vital to have a professional inspect the problem and make recommendations for repairs.
