What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in New Zealand typically run above the national range; smaller towns below it.

Frequently asked questions
Is professional tile cleaning safe for natural stone?
Marble, travertine and limestone need pH-neutral chemistry — acid-based tile cleaners etch them permanently. Tell the company your surface type up front; stone-safe cleaning and polishing is a different (pricier) service from ceramic/porcelain work.
Can cleaning fix discoloured or mouldy grout?
Surface dirt, grease and most mould clean off well. Grout that is stained through its depth, or was never sealed and has absorbed years of dirty mop water, may only lighten. The fallback options are grout colour-sealing or re-grouting.
What does professional tile and grout cleaning involve?
An alkaline pre-treatment to break down grease and soap scum, machine agitation with rotary brushes, then high-pressure hot water extraction that vacuums the dirty water away. It reaches into grout pores that mopping never touches.
Why does my grout get dirty again so fast after mopping?
Mopping pushes dirty water into porous grout lines, which sit lower than the tile face and act as gutters. After a professional clean, sealing the grout and switching to a flat microfibre mop with frequent rinse water dramatically slows re-soiling.
How long does tile and grout cleaning take?
A typical kitchen or bathroom floor takes 1-2 hours; a whole-house tiled floor half a day. Floors are walkable almost immediately after extraction, but wait 24 hours before wet-mopping, and longer if sealer was applied.
Should grout be sealed after cleaning?
Yes for cement-based grout — a penetrating sealer slows re-staining and makes mopping more effective. Sealing is pointless on epoxy grout (already non-porous). Expect sealer to add meaningfully to the bill and need reapplying every 1-3 years in wet areas.
How is tile and grout cleaning priced?
Almost always by floor area (per square metre or square foot), with a minimum job charge. Sealing after cleaning, shower recesses, and heavily stained or epoxy-smeared grout cost extra. Wall tiles are quoted separately from floors.
Can tile cleaning fix mouldy shower grout in NZ homes?
Surface mould cleans and sanitises well, but mould rooted deep in unsealed grout or failing silicone will return — budget for re-siliconing and sealing, plus better extraction/ventilation, or it reappears within months in a damp bathroom.
