Laundry Tile Regrouting

Step 1: Remove the Old Grout

Using a manual grout saw or a cordless multi-tool fitted with a grout removal blade, we carefully rake out the old deteriorated grout to a depth of at least 3 to 5mm. This gives the fresh grout enough room to bond securely and do its job properly.

Step 2: Clean Thoroughly

Once the old grout is out, we vacuum away all the dust and loose particles, then wipe down the tile joints with a damp cloth to remove any remaining debris. Getting the joints completely clean is essential, new grout won't bond well to a dirty surface.

Step 3: Mix and Apply Fresh Grout

The grout is mixed with water to a smooth, toothpaste-like consistency, not too wet, not too stiff. Using a rubber grout float held at a 45-degree angle, we work the grout into the joints without removing the tiles to fill them completely and eliminate any air pockets. 

Step 4: Clean Off the Haze

After allowing the grout to firm up for 15 to 20 minutes, we wipe away the excess from the tile faces using a slightly damp sponge and circular motions, rinsing the sponge frequently to keep the finish clean.

Step 5: Cure and Seal

The grout is left to cure for 24 to 72 hours depending on the product used and the humidity in the room. Once fully cured, silicone sealant is applied along the corners where the floor meets the wall and around the laundry tub - the spots most vulnerable to water pooling and movement.

Because the laundry is one of those rooms that doesn't get inspected very often, grout damage can quietly build up without you noticing. Here are the most common signs that it's time to regrout:

• Visible cracks or crumbling - If your grout is splitting, chipping, or breaking apart, it has already stopped doing its job and water is likely getting through
• Mould that keeps coming back - Surface mould that returns no matter how many times you clean it is a sign that moisture is trapped deep in the grout, not just sitting on top
• Discolouration and staining - Grout that has turned brown, grey, or black and won't respond to cleaning products has deteriorated beyond a simple scrub
• A musty or damp smell - If your laundry smells musty even after a thorough clean, there's a good chance moisture is hiding behind your tiles
• Loose or hollow-sounding tiles - Tap your tiles gently. A hollow sound means the bond underneath has broken down, often due to water getting in through failed grout
• Grout sitting below the tile surface - When grout has worn down and recessed below the tile edge, water pools in the joints instead of draining away
• Damp walls or water marks - Staining or moisture on the walls near your washing machine or tub is a strong sign that water is escaping through cracked grout

Catching these signs early makes a huge difference. A small regrouting job now is always going to be cheaper and less disruptive than dealing with water damage later.

• Eliminate mould for good - Cracked and porous grout in a wet area like a laundry is a breeding ground for mould and mildew. Fresh grout seals those gaps and gives mould nowhere to grow
• Stop water damage in its tracks - Deteriorating grout lets water sneak behind tiles and into your walls and subfloor, causing damage that's far more expensive to fix than a simple regrout
• Keep your laundry hygienic - Old, stained grout harbours bacteria and grime that regular cleaning can't fully remove. Fresh grout means a genuinely clean surface
• Avoid costly repairs down the line - Regrouting is a fraction of the cost of repairing water-damaged walls, flooring, or cabinetry
• Restore the look of the room - A fresh regrout makes a noticeable difference to how clean and well-maintained your laundry looks and feels
