➜ Natural Stone Cleaning & Sealing

Natural stone is porous, and protective sealers gradually wear with everyday use, cleaning and exposure. Over time, stone and grout can absorb moisture, oils and spills more easily. Colorado Stone & Tile Care deep cleans marble, granite, travertine, limestone, tile, and grout, then applies the appropriate protective treatment when needed. The result is a cleaner, refreshed surface with protection selected specifically for the material and its condition. It is the routine care that keeps stone surfaces protected, color-rich, and looking their best in Denver, CO homes and commercial properties year after year.

CLEANING AND SEALING WORK BEST AS A PAIR.

Cleaning lifts the grime that dulls your stone, but on its own it leaves the surface just as thirsty as before, ready to drink up the next spill. Sealing without a proper clean simply locks that dirt in. Done together, in the right order, they first refresh the color and then defend it, which is exactly why we almost never do one without the other.


The payoff is stone that looks brighter today and stays that way longer, with spills you can wipe up instead of scrub out.

  • Fresh penetrating sealer applied
  • Improved color and clarity
  • Easier ongoing maintenance

➜ NATURAL STONE CLEANING & SEALING

A DEEP CLEAN REACHES WHAT DAILY MOPPING NEVER WILL.

Routine mopping removes everyday surface soil, but it can't always reach embedded residue, mineral buildup and contaminants that collect in porous stone and grout. Our professional cleaning process uses stone-safe products, agitation and extraction methods selected for the material to remove buildup without unnecessarily damaging the finish.

THE FRONT RANGE RUNS HARD ON STONE AND GROUT.

Hard water is common throughout the Front Range, and mineral deposits can leave cloudy residue on showers, spotting on counters and stubborn buildup in grout. Left alone, that residue dulls the surface, clings to the pores, and traps even more dirt over time. We remove the mineral buildup during cleaning, then seal the stone to make every future round of upkeep far easier to manage.

WE KNOW WHICH SEALER BELONGS ON WHICH STONE.

Not every sealer is appropriate for every surface. Dense granite, porous travertine, limestone and grout can require different products, application methods and dwell times. With 15+ years of specialized stone-care experience, we select protective treatments based on the material, finish, condition and how the surface is used.

WHAT PROPER CLEANING AND SEALING DELIVER.

GREATER RESISTANCE TO STAINS

A properly selected sealer helps reduce absorption, giving you more time to clean up spills before they penetrate the surface.

A CLEANER, REFRESHED APPEARANCE

Deep cleaning clears the film that grays out natural stone, and the true color and veining return. Surfaces look richer and brighter, often better than they have in years of routine mopping.

Grout That Looks Clean Again

Heated extraction pulls soil out of porous grout lines that hand scrubbing never reaches. The lines lighten several shades, and sealing helps them resist the next wave of dirt and moisture.

Protection Against Moisture

Sealed stone helps reduce moisture that leads to staining, mildew, and slow deterioration. This matters most in kitchens and baths, where surfaces meet moisture and spills all day long.

Easier Everyday Upkeep

Once stone is properly cleaned and sealed, routine care gets simpler. A quick wipe with a pH-neutral cleaner keeps it looking good, and you spend far less time fighting stubborn buildup.

More Years From Your Stone

Regular professional cleaning and appropriate sealing help reduce staining, buildup and premature surface wear, protecting the stone you already own and helping preserve its appearance over time.

➜ WHAT WE CLEAN & SEAL

OUR STONE CLEANING & SEALING WORK

Whether it is a single kitchen island or every stone floor in a building, we clean and seal the full range of surfaces. These are the projects we handle most for Denver homes and businesses.

DEEP CLEAN

Deep Stone Cleaning

Heated water, safe degreasers, and mechanical agitation lift soil out of the pores instead of pushing it deeper. Marble, granite, travertine, and limestone come back clean, bright, and ready to be sealed.

SEALING

Penetrating Sealer Application

A penetrating sealer soaks into the stone to slow staining and moisture without changing its look. We match the product to your material and apply it evenly for protection that actually lasts.

ENHANCE

Color-Enhancing Sealing

For stone whose color has faded, an enhancing sealer deepens the tone and richens the veining while still protecting the surface. It gives travertine and slate a warmer, wet-look finish.

SHOWERS

Soap Scum & Buildup Removal

Bathrooms collect soap film, body oils, and hard-water minerals that dull stone and grout. We strip that buildup away and reseal, so the surfaces look clean and shed water instead of holding it.

GROUT

Grout Cleaning & Sealing

Porous grout absorbs everything that lands on it. We deep clean the lines to lift years of embedded soil, then seal them so they stay lighter and resist staining far longer between cleanings.

PROGRAMS

Ongoing Care Programs

For busy households and commercial sites, we set a simple recurring schedule of cleaning and resealing. Your stone stays consistently protected, and small issues get caught long before they turn into damage.

➜ THE WORD ON OUR WORK

WHAT OUR CLIENTS SAY.

Clients tell us the change is hard to believe: counters they thought were permanently stained came back bright, and showers that always looked cloudy finally read as clean. The recurring theme is stone that looks cared for again, and stays that way between visits.

➜ Common Questions

FREQUENTLY ASKED QUESTIONS.

The questions Denver homeowners ask most about keeping natural stone clean, sealed, and protected, so you know what these services can and cannot do for your surfaces.

  • Does sealing prevent marble and other stone from etching?

    No. A penetrating sealer reduces how much liquid and stain the stone absorbs, but it does not stop acidic substances from etching marble, travertine, or limestone. A dedicated surface protector is recommended when etch resistance is the priority.

  • How can I tell when my stone or grout needs to be resealed?

    Darkening where water sits, faster staining, and quick moisture absorption all signal the sealer is wearing out. Because resealing schedules vary by material, traffic, and cleaning habits, an evaluation is more reliable than following a fixed timeline.

  • How often should natural stone be sealed?

    It depends on the stone and how hard the surface works. Busy kitchen counters often need resealing every year or so, while low-traffic areas last longer. A quick water-absorption test shows when protection has faded.

  • Can you clean stone without damaging the finish?

    Yes. We use pH-neutral, stone-safe products and heated water rather than harsh acids or abrasives. The process lifts soil and buildup while leaving the polish or honed finish and the stone itself unharmed.

  • Why does my stone look hazy after I clean it myself?

    Household mops and cleaners often leave a film of dirty water or product residue in the pores. Our extraction process removes that film entirely, which is why professionally cleaned stone looks clearer afterward.

  • Will sealing change how my stone looks?

    A standard penetrating sealer is invisible and keeps the current look. If you want richer color, we can apply an enhancing sealer instead, which deepens the tone. We confirm which finish you prefer first.

  • Is professional cleaning worth it if I clean regularly?

    Regular home cleaning handles surface dirt, but it cannot reach soil trapped deep in the pores or in grout. Colorado Stone & Tile Care removes that buildup for homes across Denver, CO, then reseals for lasting protection.

  • Can you clean and seal stone in a shower?

    Yes. Showers are among the most common surfaces Colorado Stone & Tile Care treats across Denver, CO, since constant water and soap create heavy buildup. We deep clean the stone and grout, repair as needed, and reseal.

➜ HOW WE WORK 

FROM GRIMY TO PROTECTED, HERE IS HOW.

STEP 01

We Inspect And Test

We identify the stone, check the current sealer with a water test, and note problem areas. This shows us how heavy the cleaning needs to be and which sealer the surface will take best.

STEP 02

We Prep The Area

Surrounding floors, cabinets, baseboards, and fixtures are protected, and we clear the surface completely. Getting the space ready keeps the cleaning contained and ensures nothing but your stone gets treated during the process.

STEP 03

We Deep Clean

Safe degreasers and heated water are worked into the stone, then extracted along with the loosened soil. This lifts grime out of the pores and grout rather than smearing it back across the surface.

STEP 04

We Let It Dry

Sealers only bond to fully dry stone, so we allow the surface the drying time it needs. Rushing this step is what causes hazing and short-lived sealer, so we do not skip it.

STEP 05

We Apply The Sealer

The right penetrating or enhancing sealer is applied evenly and given time to soak in, then any excess is removed. This builds real protection into the stone without leaving a sticky or cloudy residue.

STEP 06

We Guide Your Care

We finish by showing you the simple pH-neutral routine that keeps the surface protected, and we note when resealing will be due. You leave knowing exactly how to make these results last as long as possible.
