Dark or Dirty Grout

Modern Stone Care cleans and seals grout in Houston homes and businesses.

If your grout lines look dark, greasy, or stained no matter how much you mop, we can deep clean them and seal the joints so they stay cleaner longer.

What’s Going On

Grout is porous. It soaks in oils, soap film, and mop water. Dirt packs into the joints and makes the lines look dark. In kitchens, grease and spills speed this up. In showers, soap film and hard water leave a sticky layer that traps soil.

FAQs

Will cleaning bring grout back to the original color?

Usually yes if it is soil and film. If stains remain after cleaning, we can discuss color sealing to even the tone.

How long does grout sealer last?

Kitchens and entries often need a yearly check. Lower traffic areas can go longer. We will advise based on use.

Can you clean natural stone tile safely?

Yes. We use stone-safe chemistry and methods around marble, travertine, limestone, and slate.

Do you use high pressure?

No. We use controlled hot water and vacuum recovery to protect grout and edges.

How soon can we walk on it?

Light foot traffic is usually fine after we finish. If we seal, we provide simple cure times.

Review by Bruce G.

Modern Stone Care did a first rate professional job on cleaning and sealing the travertine tile on our rear patio and front entranceway. See photos. They were on time and were a pleasure to work with. They explained the process as the work was done. All of our furniture was moved out of the way and when the work was done placed back.

Review by Stevem B.

Modern Stone Care did a great job on restoring 29 year old travertine kitchen floor tile. They also showed us how to keep care of the floor tile. Price was very fair. Not supposed to use Pine Sol, as not good for floor stone (I have been using Pine Sol for last two years).. MSC polished the stone and restored its sheen. Great job!

Review by Kevin S.

We had Modern Stone Care refinish our countertops. They let us see a matte finish before doing all of the countertops and after we saw it we really liked it. It only took them a couple of hours. They did a great job and I would definitely use them again

Review by Scott B.

What an amazing job modern stone care did on my marble floors, oh my goodness! I’ve never had my marble floors cleaned until today, now I regret not doing it sooner. I highly recommend this company to anyone wanting to see a significant improvement and their stone floors. Really nice folks who come to the house and they leave the house very clean and neat.
