Do your tiles sound hollow when tapped, feel loose underfoot, or show signs of cracking or moisture damage? These are common indicators of drummy tiles — a problem that should be addressed early to prevent further floor damage.

In this guide, we explain what drummy tiles are, what causes them, how to fix them, and whether they can be repaired without retiling.

What Are Drummy Tiles?

Drummy tiles are tiles that produce a hollow, drum-like sound when tapped. This happens when the tile has partially or fully lost its bond with the adhesive or screed beneath it.

Although tiles may initially appear intact, drummy sounds usually indicate underlying adhesion failure that can worsen over time.

What Causes Drummy Tiles?

Drummy tiles typically develop due to one or more of the following issues:

  • Insufficient adhesive coverage beneath the tile
  • Incorrect adhesive type for the substrate or environment
  • Poor adhesive application technique
  • Water or moisture ingress, often from leaks or failed waterproofing
  • General wear and movement over time

Identifying the underlying cause is essential, as it determines whether the tiles can be repaired or must be replaced.

Can Drummy Tiles Be Fixed Without Retiling?

Yes — drummy tiles can sometimes be fixed without retiling, depending on the extent of the damage.

If the tiles are:

  • Not cracked
  • Not lifting or swollen
  • Only slightly loose with limited hollow areas

…then non-invasive repair methods may be effective.

However, if the drummy sound is widespread, tiles are moving, or water damage is present, retiling is usually unavoidable to ensure a long-term solution.

How to Fix Drummy Tiles: Repair Options

Option 1: Fixing Drummy Tiles Without Retiling (Epoxy Regrouting)

If tiles are still structurally intact, epoxy regrouting can help stabilise them.

This method involves:

  • Opening existing grout joints to approximately 2 mm
  • Removing compromised grout
  • Replacing it with epoxy grout, which offers superior strength and water resistance

Epoxy grout can help redistribute load and limit movement, making it a practical solution for minor drummy tile issues.

Best for:

  • Small affected areas
  • Early-stage adhesion failure
  • Tiles without cracking or moisture damage

Option 2: Retiling (When Drummy Tiles Are Beyond Repair)

If a large portion of the tiled area is affected, or if tiles are:

  • Lifting or swelling
  • Cracked due to movement
  • Affected by water damage

…then a full or partial retile is the most reliable solution.

This process includes:

  • Removing loose tiles and old adhesive
  • Repairing or replacing damaged substrates or membranes
  • Preparing the surface correctly
  • Relaying tiles with appropriate adhesive coverage

Retiling ensures the problem is fully resolved rather than temporarily masked.

What Happens If Drummy Tiles Are Left Unrepaired?

Ignoring drummy tiles can lead to:

  • Tile cracking or breakage
  • Moisture penetration and waterproofing failure
  • Further adhesive breakdown
  • Higher repair costs over time

Early intervention often allows for simpler, less disruptive repairs.

Should You Fix Drummy Tiles Yourself?

DIY tile removal and adhesive scraping can easily cause more damage than intended. In many cases:

  • Waterproof membranes are torn during tile removal
  • Structural substrates are compromised
  • Manufacturer warranties become void

Professional assessment ensures the correct repair method is chosen the first time, avoiding unnecessary rework.
