Grout & Tile Cleaning Questions, Answered

In almost every case, dirty or stained grout can be professionally cleaned and restored rather than replaced. High-pressure extraction and specialized solutions pull years of built-up dirt out of the porous grout, delivering like-new results for a fraction of the cost of new tile — which is why our motto is don’t replace it, restore it.

Grout still looks dirty after mopping because a mop pushes dirty water down into the porous grout lines instead of lifting it out, and that residue builds up and darkens over time. Only professional deep-extraction cleaning removes the embedded grime, and sealing afterward keeps dirt from soaking back in. More on why grout looks dirty after mopping.

Most Boise-area homes should have their tile and grout professionally cleaned every one to two years. High-traffic areas, showers, and homes with children or pets benefit from more frequent cleaning to keep the grout from staining and darkening. See our guidance on cleaning frequency.

Clear sealing protects grout while keeping its current color, while color sealing both seals the grout and applies a uniform new color that hides stains and discoloration. In short, color sealing gives grout a brand-new look without replacing it, and clear sealing simply preserves and protects the color that’s already there. Compare clear vs. color sealing.

Yes, color sealing can change the color of your grout. It lets you restore the original shade or switch to a completely new color, which is an easy way to refresh a room’s look without a remodel.

A clear penetrating grout sealer typically lasts one to three years, depending on foot traffic and how the surface is cleaned. Color sealing lasts significantly longer because it acts as a durable, stain-resistant coating bonded over the grout.

Yes, natural stone such as travertine, marble, and slate should be sealed because it is porous and prone to etching and staining. Sealing protects the stone from stains and moisture and keeps it looking its best. Why natural stone sealing matters.

Loose or hollow-sounding tiles usually do not need to be replaced. In most cases they can be re-bonded in place, which is faster and far less expensive than tearing them out and installing new tile. How re-bonding beats replacing.

In most cases, regrouting and restoring a shower is a better choice than replacing it. Restoration costs a fraction as much, takes about a day instead of a week, and leaves the shower looking new. When repair beats replacement.

Grout fills the joints between tiles, while caulk seals the corners and the seams where tile meets a tub, floor, or wall — areas that flex and move. Using grout and caulk in the right places prevents cracks and leaks. Grout vs. caulk, and where each goes.

Black shower caulk is almost always mildew growing in trapped moisture. The fix is to remove the old caulk and replace it with fresh, mildew-resistant caulk, because cleaning alone will not restore it. How to fix black shower caulk.

A shower should generally be recaulked every one to two years, or sooner if the caulk cracks, pulls away from the surface, or turns dark. Recaulking tips and timing.
