Tile & Grout Cleaning in Christchurch

Grout is porous by design, which is exactly why it goes grey years before the tile around it shows any wear — it absorbs everything that touches it and mopping only ever cleans the surface. PrestigePro restores tile and grout across Christchurch, from $5/sqm. WHY MOPPING NEVER ACTUALLY CLEANS GROUT A mop moves dirty water across a surface — it doesn't extract anything, and on porous grout it can push grime further into the material rather than lifting it out. Years of this is what turns white grout grey or beige, not a single dirty mop or a one-off mess. Restoring it needs something that pulls the embedded dirt back out, not just wipes over the top of it. HOW ROTARY EXTRACTION WORKS Our equipment combines high-pressure water with immediate extraction in the same pass — dirt is blasted out of the grout lines and vacuumed up before it has a chance to resettle into the joint or migrate onto the tile. This is the difference between genuinely restoring grout colour and just making it look better while wet, which is what a lot of DIY grout cleaning products actually deliver. KITCHEN VS BATHROOM: DIFFERENT PROBLEMS, DIFFERENT TREATMENT Kitchen floor grout collects grease and cooking residue that builds up in a sticky film most general cleaners can't cut through. Bathroom grout deals with soap scum, body oils, and near-constant moisture, which is what encourages mould and mildew growth in shower grout specifically. We treat these as different jobs rather than running identical product and pressure over both. SEALING IS WHAT MAKES THE RESULT LAST Grout without a sealer is exactly as absorbent the day after cleaning as it was before — it will re-stain at the same rate unless it's sealed. Sealing fills the pores in the grout so future spills and grime sit on the surface instead of soaking in, which is what actually makes ongoing mopping effective again. Skipping this step is the most common reason a grout clean looks great for a month and then fades back. NATURAL STONE NEEDS DIFFERENT PRODUCTS ENTIRELY Marble, travertine and other natural stone are calcium-based and etch — literally get chemically damaged — when cleaned with the acidic products that work fine on ceramic tile and grout. We use pH-neutral, stone-safe products on natural stone specifically, because the wrong product doesn't just fail to clean it, it can permanently dull or mark the surface. OUTDOOR AND COMMERCIAL TILE Outdoor pavers and patio tiles pick up moss, algae and general weathering the same way driveways do, and respond well to the same restoration approach. Commercial kitchens and hospitality floors see far heavier grease and foot traffic than a home ever will, so restaurants and cafés typically need this done more often than a residential bathroom to keep floors looking presentable and genuinely hygienic.
