Compare QuotesWhen Regrouting Is the Right Fix
| Problem | Regrout? |
|---|---|
| Stained or discoloured grout, tiles sound | Yes |
| Cracked or crumbling grout, tiles firm | Yes |
| Mould in grout lines | Yes, with better ventilation |
| Loose or hollow tiles | No. Repair the tiles first |
| Damp wall next to the shower or stain on the ceiling below | No. Waterproofing has likely failed |
Regrouting does not repair waterproofing. Grout is not a waterproof layer. If water is reaching the wall, floor or ceiling below, the membrane under the tiles has probably failed. See shower waterproofing.
Choosing Replacement Grout
| Grout | Good for | Note |
|---|---|---|
| Cement-based grout | Most walls and floors | Affordable. Benefits from sealing in wet areas |
| Polymer-modified grout | Showers, floors | Better flexibility and stain resistance |
| Epoxy grout | Showers, kitchens, commercial areas | Highly stain- and mould-resistant, costs more |
A darker grout hides staining on floors. A full colour change needs all the old grout removed to an even depth.
How Regrouting Is Done
- Remove old grout to a good depth with a grout saw or oscillating tool, without chipping tile edges.
- Clean out dust and treat mould.
- Pack new grout firmly into the joints.
- Clean off the haze.
- Replace silicone at corners, baths and basins.
- Seal cement grout if recommended.

Frequently Asked Questions
Can new grout go over old grout?
Not reliably. A thin layer over old grout cracks and falls out. Old grout should be removed to a good depth.
Will regrouting stop my shower leaking?
Only if the leak is minor and through the grout itself. Most shower leaks come from failed waterproofing, which regrouting does not fix.
How long before I can shower after regrouting?
It depends on the grout. Many need around a day or more. Ask the tiler for the product's cure time.
How do I stop mould coming back?
Ventilate the room, run an extractor fan and dry the shower after use. Epoxy grout resists mould better.
Can I change grout colour?
Yes, by removing the old grout. Grout colourants are an option for sound grout but are a surface coating.
