How Often Should You Clean and Reseal Tile and Grout?

Tile floors look low-maintenance, and the tile itself mostly is. The grout is another story. Those lines between the tiles are porous, which means they soak up grime, grease, mildew, and moisture — and a mop only pushes that around. Here’s how often tile and grout actually need professional attention, and how to tell when yours is overdue.

Why grout is the weak point

Tile is hard and non-porous; grout is soft and porous. Every spill, mopping, and footstep drives a little more soil into those lines. Over time it darkens, discolors unevenly, and — in damp rooms — grows mildew. In humid parts of Virginia, from Richmond’s long muggy summers to the salt-air humidity of Hampton Roads, grout stays damp longer and discolors faster.

Unsealed or worn-sealed grout is the real problem: once the protective sealer wears off, moisture and stains soak straight in.

How often to clean and reseal

A good rule of thumb:

• Professional deep clean: every 12–18 months for most homes; more often in high-traffic kitchens, mudrooms, and entryways, or homes with kids and pets.
• Reseal grout: every 1–3 years, depending on traffic and the sealer used. Showers and busy floors are on the shorter end.
• Daily/weekly: sweep and damp-mop with a pH-neutral cleaner — skip the acidic and bleach-heavy products that erode sealer and grout over time.

Signs your grout is overdue

• Grout lines that are darker than they used to be, or discolored unevenly.
• Mildew spots in shower or floor grout.
• Water soaking into the grout instead of beading on top (a sign the sealer is gone).
• A bathroom that smells musty no matter how often you clean.

Why professional cleaning + sealing beats DIY

You can scrub a grout line with a brush and a homemade paste — and many people do, on their knees, for hours, with mixed results. Professional tile and grout cleaning uses heat, pressure, and the right solution to pull grime out of the pores, then lays down a fresh sealer that keeps the next round of moisture and staining on the surface where it wipes away. The result lasts far longer than hand-scrubbing, and it’s a lot easier on your knees.
