Grout Sealing

The single best thing you can do after a professional cleaning — seal your grout to lock out stains, moisture, and mold before they take hold.

Grout is a porous material. Without a sealer, it absorbs spills, soap scum, hard water minerals, and mold spores almost immediately. A professional-grade penetrating sealer fills those pores at the microscopic level, creating an invisible barrier that repels liquids and makes your grout dramatically easier to keep clean.

Why sealing matters

Unsealed grout stains within weeks of installation or cleaning. Once staining is deep enough, no amount of scrubbing will remove it — the only options are recoloring or re-grouting. Sealing is far cheaper and easier than either of those. We recommend sealing after every professional cleaning to reset the clock on your grout's protection.

Penetrating vs. topical sealers

We use penetrating (impregnating) sealers that absorb into the grout rather than sitting on top of it. Topical sealers peel and wear off quickly, especially in high-traffic areas. Penetrating sealers bond with the grout itself and last significantly longer — typically 3–5 years depending on traffic and cleaning habits.

The process

We apply sealer after the grout is fully clean and dry. The sealer is worked into the grout lines and allowed to penetrate, then any excess is wiped from the tile surface. The grout needs to cure for a few hours before it gets wet, and we'll walk you through the care instructions before we leave.

Frequently Asked Questions

How long after sealing can I use the shower or floor?
We recommend waiting 2–4 hours before getting the grout wet. We'll give you the exact cure time based on the sealer we use.
How often should grout be sealed?
Every 2–3 years for most floors, and every 1–2 years for shower grout which sees constant moisture. A simple water-bead test tells you when it's time — if water soaks in instead of beading up, it's time to reseal.
Can you seal grout without cleaning it first?
We strongly recommend cleaning first. Sealing over dirty grout locks the stains in permanently. We always clean before sealing.
Does sealing change the look of the grout?
Penetrating sealers are invisible — they don't change the color or sheen of your grout. We also offer color-seal products if you want to change or enhance the grout color at the same time.
