A quality tile installation is pretty durable. But tiles and grout cannot last forever, or at least not look new forever. Over the years the daily wear, effects of moisture, and plain old aging can cause damage that affects both the look and function bathroom and kitchen. In some cases older tile designs just fall out of fashion. Knowing when to replace the tiles, and knowing when it is better to just regrout, can save you time and money, while still giving a good quality result.

Signs That a Regrout a Floor is Enough
Regrouting is often the quickest and most cost-effective way to refresh older tiled surfaces without replacing the tiles. The grout between the tiles can crack over time, leaving the floor prone to moisture issues. If we replace the grout, the tiled floor can look almost like new, and be completely waterproof.
1. Cracked or Crumbling Grout
If you see fissures, gaps, or pieces of grout falling out, it means the grout is failing. This allows water to seep beneath tiles, leading to mould, leaks, and possible structural damage.
2. Discolouration and Stains
When grout stays yellow, brown, or grey even after scrubbing, it’s usually beyond cleaning. Bleach or chlorine can sometimes remove the discolouration. But if the stains are permanent, it means the grout has almost certainly absorbed moisture or mould, and is best replaced.
3. Mould and Mildew Growth
Bathrooms and kitchens are especially prone to mould. Ventilation fans help prevent this, as does regular cleaning. But if black spots or mildew on a tiled floor keep coming back, despite our best efforts, the grout has become porous and can no longer protect the tiles properly.
4. Loose or Wobbling Tiles
Grout helps keep tiles firmly in place. When it breaks down, tiles may shift or lift from the surface. This weakens the waterproof barrier and makes regrouting necessary.
Signs You Need to Retile the Floor
Sometimes, the problem goes beyond grout and the tiles themselves need replacing.
1. Cracked or Chipped Tiles
Damaged tiles are not just an eyesore. Any cracks will allow water to reach the substrate underneath, which strongly risks causing long-term damage. This should be addressed promptly before the damage is too bad.
2. Loose or Hollow-Sounding Tiles
If tiles wobble or sound hollow when tapped, they have almost certainly lost their bond to the underlying surface. This can be caused by water that has seeped behind the tile, or by a poor adhesive.
3. Water Damage and Mould
Dark spots, moisture seeping through, or musty odours can indicate water damage behind the tiles. In these cases, tile replacement may be the only way to properly fix the problem.
4. Outdated Appearance
Even if your tiles are intact, faded colours, scratches, or an old-fashioned style can make a bathroom or kitchen feel tired. Retiling is often the best way to modernise the look of your space.
5. Structural Issues
If the substrate beneath the tiles is compromised, regrouting alone won’t solve the problem. The tiles will need to be removed and the surface repaired.
When A Combination of Both May Be Necessary
Some situations require both regrouting and some retiling. If any of the tiles are damaged, loose, or if they make a hollow sound when tapped, then they need either replacing, or perhaps reapplied with new adhesive.
Why Regrouting Matters
Even if tiles don’t need replacing, fresh grout makes a big difference. It can:
- Prevent leaks and water damage by restoring the waterproof seal
- Stop mould and mildew from spreading
- Improve hygiene and indoor air quality in damp spaces
- Refresh the appearance of tiles for a fraction of the cost of retiling
- Change the appearance by using a coloured grout. The right combination of tile and grout colour can be very effective.
With professional regrouting, old grout is removed, the area is cleaned, and a durable new grout is applied. This restores both function and appearance, often making the entire tiled area look new again.
Final Thoughts
Good tiling can last for decades. But nothing lasts forever, and sometimes damage can occur. In some cases, if the issue is mould or stains and cracks in the grout, then a regrout is enough to restore the tiled floor. In other cases, when the tiles themselves are damaged, or there are problems in the subfloor, then retiling may be the only option. If we keep an eye out for any warning signs then we can tackle any problems before they are too serious. And can understand when retiling or just regrouting is required.
