Tile and grout cleaning costs $0.92–$2.05 per square foot depending on material — $276–$366 for a typical 300 sq ft ceramic floor, up to $465–$615 for natural stone. Here's what drives the price, plus sealing and recoloring costs.
Tile and grout cleaning is priced per square foot, and the material matters more than most people expect — the difference between ceramic and natural stone can add over 60% to your bill, because natural stone needs gentler, pH-neutral products that take more time to work properly.
Here's what that actually works out to for ceramic tile, the most common material:
Mopping just moves dirty water across the surface — it can't scrub grout lines, which are porous and trap soap scum and body oils in showers, cooking grease in kitchens, foot-traffic grime on floors, and mold or mildew anywhere moisture sits. That's why grout that started out white or light gray gradually darkens no matter how often you mop.
Sealing runs $0.55–$0.88 per square foot on top of cleaning, and most companies discount it 20–30% when bundled with a cleaning visit rather than booked separately. Sealed grout repels water and stains for 2–5 years — skip it, and grout will re-darken noticeably faster, which usually means paying for a full cleaning again sooner than you'd like.
If cleaning alone doesn't fully restore badly stained grout, recoloring is the next option: a colorant penetrates the porous grout and covers deep, set-in staining with a uniform color, rather than trying to lift it out. It costs $1.65–$2.55 per square foot and results typically hold up 5–10 years with normal maintenance. It's worth it for grout that's discolored beyond what cleaning can fix, rather than paying to replace the grout entirely.
Heavily soiled or damaged tile and grout costs 32–55% more than lightly soiled tile — the extra time goes into more aggressive pre-treatment and, in the case of damage, prep work around cracked or chipped grout lines before cleaning can even begin.
For light-to-moderate soiling, a baking soda paste and a stiff brush genuinely helps. Oxygen bleach-based cleaners ($15–$30 a bottle) and a grout brush drill attachment ($10–$20) go further. Where professional equipment wins is pressure and heat — 200+ PSI steam loosens embedded grime that hand scrubbing physically can't move, which is the whole reason grout darkens permanently over time if it's never professionally cleaned.
How much does tile and grout cleaning cost?
For a typical 300 sq ft area, ceramic tile cleaning costs $276–$366. Natural stone costs more, at $465–$615, due to the specialized products required.
How much does it cost to clean tile and grout in a bathroom?
A small bathroom (around 50 sq ft) usually falls under the $150–$200 whole-project minimum rather than the raw per-square-foot rate, since most bathrooms are too small to exceed it.
How much does grout cleaning cost by itself?
Grout cleaning isn't typically sold separately from tile cleaning — the same pass that cleans the tile surface cleans the grout lines, priced together at $0.92–$2.05/sq ft depending on material.
Is grout sealing worth it?
Yes — sealing ($0.55–$0.88/sq ft) protects grout from future staining and meaningfully extends the time between deep cleanings, which usually makes it cheaper over a few years than skipping it.
Can discolored grout be restored without replacing it?
Yes — grout recoloring ($1.65–$2.55/sq ft) applies a durable colorant that restores a uniform, like-new appearance without tearing out the existing grout.
