Why Do Floor Tiles Pop Up? Causes, Fixes & What to Look For

Written By Zachary Allgeyer

If you've noticed a tile suddenly lifting or making a hollow sound underfoot, you're likely dealing with tile popping—also known as "tenting." While it may seem like a minor nuisance, it can sometimes indicate deeper issues with the home. That’s where a professional inspection can help.

What Causes Tile Popping?

Several common causes include:

Tile tenting caused by structural shifts. Picture shows aftermath of an earthquake.

  • Improper Adhesive Application
    Inadequate or uneven adhesive leaves tiles vulnerable to movement over time.

  • Uneven Subfloor
    An unlevel or shifting subfloor can compromise how well tiles bond to the surface.

  • Moisture Infiltration
    Moisture—especially in kitchens or bathrooms—can weaken adhesives and contribute to lifting.

  • Thermal Expansion
    Without proper spacing, tiles can press against each other as temperatures fluctuate, causing them to pop.

  • Structural Shifts
    Homes naturally settle. If tile installations don’t allow for this, tension builds and tiles can break loose.

What Should You Do?

If you see popped or loose tiles, it’s important to determine the underlying cause. While some cases are cosmetic and easily repaired by a tile professional, others may hint at moisture problems, foundational shifts, or poor installation techniques.
