Q: What is color sealing and when do I need it?
Color sealing is a pigmented epoxy coating applied directly to grout joints in any color you pick. It locks in a uniform shade, waterproofs the joint, and lasts 10 to 15 years on floors. You need it when cleaning alone won't bring the grout back, usually because of permanent staining, pigment loss from old colorant, or because the original grout shade just looks dirty even when it's clean. We test a small area first so you can see the color before we commit.
Q: How long does grout sealing actually last?
A penetrating impregnator sealer lasts 2 to 5 years on floor grout, less in showers and kitchens that get heavy moisture and cleaner exposure. Color sealing lasts 10 to 15 years because it's a coating on top of the grout, not just an absorbed sealer. We recommend resealing floor grout every 3 years as cheap insurance against the next deep stain.
Q: Can you fix cracked, crumbling, or missing grout?
Yes. Damaged grout gets removed with an oscillating tool and refilled with color-matched cement or epoxy grout depending on the location. Wet areas like shower floors and walls we recommend switching to epoxy grout because it doesn't absorb moisture or grow mold the way cement grout does. We do the regrout before any cleaning or sealing so the whole floor finishes uniformly.
Q: What about mold in shower grout?
Most surface mold lifts out with our antimicrobial pretreatment plus steam extraction. Deep mold that has penetrated below the visible joint may have already gotten into the substrate behind the tile, in which case the grout has to come out and the area gets inspected for water damage. We tell you which situation you have during the walk-through, and either way the visible black goes away.
Q: Why does my grout get dirty so fast after I clean it?
Two reasons. First, household mops just push dirt around and a lot of it ends up in the grout joints, which sit lower than the tile surface. Second, if the grout has never been sealed or the sealer has worn off, the cement is essentially a sponge that absorbs whatever liquid hits it. Professional cleaning plus a fresh sealer breaks the cycle, and after that, regular mopping actually keeps the floor looking clean.
Q: Should I switch from cement grout to epoxy grout?
For showers and other constantly wet areas, usually yes. Epoxy grout doesn't absorb water, doesn't grow mold, and doesn't need sealing. For kitchen and entry floors it's optional, cement grout works fine if it's sealed and maintained. Epoxy is harder to install, costs more, and has a learning curve, so we only recommend it where the moisture problem actually justifies the upgrade.
Q: Will the cleaning damage my tile?
No. Glazed ceramic and porcelain tile are not affected by the steam, pressure, or chemistry we use. Natural stone tile gets pH-neutral chemistry instead of the alkaline cleaner we use on porcelain, because acidic or strongly alkaline products can etch stone. The walk-through identifies which tile you have so we match the process to the surface.
