Grout is porous. It absorbs dirty mop water, cooking grease and soap residue, and over time it darkens from the color it was installed in. Mopping cleans the tile and pushes soil into the grout. Professional tile cleaning uses an alkaline pre-treatment to loosen the soil, then a contained high-pressure rinse that scrubs and vacuums in one pass, pulling the dirt out of the grout instead of spreading it.

  • Pre-treatment matched to the tile and the type of soil
  • High-pressure hot water rinse with simultaneous extraction
  • Edges, corners and grout lines detailed by hand
  • Penetrating sealer applied to grout once dry
  • Kitchens, bathrooms, entries, showers and tiled living areas

What it costs

HomeAdvisor reports an average of $477 for tile and grout cleaning, with a typical range of $283 to $672, or about $0.50 to $3 per square foot. The price depends on the area, the amount of grout — small tiles mean many more grout lines — the condition, and whether sealing is included.

Sealing is what makes the result last

Cleaned grout that is left unsealed starts absorbing soil again immediately. A penetrating sealer soaks into the grout and slows that down, so spills stay on the surface long enough to wipe up. Expect to re-seal every one to two years in high-traffic areas. Color sealing goes further: it coats the grout in a uniform color, which evens out staining that cleaning cannot remove.

When cleaning will not be enough

Cleaning removes soil. It does not fix grout that is cracked, crumbling or missing, and it will not remove stains that have permanently dyed the grout or etching on natural stone. Hard-water deposits, which are common here, need an acidic treatment that is not safe for every stone. A technician should tell you before starting what will and will not come out.

Tile & Grout Cleaning FAQs

How long does tile and grout cleaning take?

A typical kitchen and a couple of bathrooms take two to three hours. Floors can be walked on shortly after cleaning. If a sealer is applied, keep the floor dry for the time the technician specifies, usually several hours to a day.

Can I clean grout myself?

For light soil, yes: a pH-neutral cleaner and a stiff nylon brush work, with plenty of rinsing. Avoid bleach as a routine cleaner and acidic products on natural stone. Deeply soiled grout needs the heat, pressure and extraction that professional equipment provides.
