Common Signs To Watch Out For

The first thing to look out for is uneven or misaligned tiles. When tiles aren’t properly spaced or level, it’s usually a sign that the installer rushed the job or didn’t prepare the surface correctly. You might notice inconsistent grout lines or tiles that slope slightly when you run your hand across them.

Another clear indicator of poor tile installation is hollow-sounding tiles. Tap gently on the surface — if it sounds hollow, it means there are air pockets underneath due to insufficient adhesive coverage. Over time, these tiles may crack or pop loose.

Finally, check the grout. Cracked, crumbling or discoloured grout is often a sign that the tiles weren’t sealed correctly or that low-quality grout was used.

Why Poor Tile Installation Happens

Most tile issues come down to poor preparation. When the subfloor or wall isn’t level, tiles will naturally sit unevenly. Using the wrong adhesive or skipping primer can also cause problems later on.

Rushing the job is another common cause. Tile installation requires patience, precision and drying time between each step. When installers skip these stages, the result may look fine at first but quickly deteriorates.

How to Fix Poor Tile Installation

If you’ve spotted issues, don’t panic. The first step is identifying how severe the problem is. For small fixes — such as uneven grout or loose edges — re-grouting or replacing a few tiles might do the trick. Make sure to clean the area thoroughly before reapplying adhesive or grout to ensure it bonds properly.

For bigger issues, such as widespread hollow tiles or major alignment problems, you might need to remove and reinstall the affected sections. In this case, it’s worth calling in a professional tiler who can assess the damage and provide a proper solution.

Preventing Tile Problems in the Future

The best way to avoid poor results is by hiring experienced professionals who know what they’re doing. Always check previous work, read reviews and ask about the installation process. Reliable tilers will take the time to prepare the surface, use quality materials and apply the correct techniques.

If you’re attempting a DIY project, make sure you follow the manufacturer’s guidelines for adhesives, spacers and grout. Don’t rush — take your time to plan your layout, level your surfaces and let everything dry fully before moving on to the next step.
