Marble. Travertine. Limestone. Saltillo. Treated right, not just cleaned.
Natural stone is one of the most valuable, and most misunderstood, surfaces in a home. The wrong chemistry, the wrong tool, or a missed seal can cause permanent damage. Pro-Fresh Houston uses stone-specific protocols to clean, restore, and protect every surface we touch.

Three levels of care. One standard of detail.
Stone Cleaning
pH-neutral, stone-safe chemistry applied and extracted without etching or stripping existing sealer. Surface dirt, grime, and buildup removed without damage to the stone.
Cleaning + Sealing
Full cleaning followed by professional-grade impregnating sealer. Protects against moisture, staining, and microbial growth, especially important in Houston's humid climate.
Full Restoration
For stone that has lost its finish, been scratched, etched, or worn over time. Includes honing, polishing, re-grout cleaning where applicable, and sealing. Returns stone to its original or better condition.
Houston humidity is the enemy of unsealed stone.
Saltillo tile, travertine, marble, and limestone are all porous. In Houston's climate, unsealed or improperly sealed stone absorbs moisture, develops microbial growth, and stains from the inside out. Surface mopping will not fix it. Pro-Fresh uses the same professional-grade chemistry and methods used in high-end restoration, not grocery-store stone cleaner.
What you get out of it.
- Stone looks new, not just mopped
- Sealed surface resists future staining and moisture
- Microbial growth eliminated, not spread
- Extends the life of expensive stone floors, walls, and countertops
- Safe chemistry, no harsh acids that etch or dull the surface
- Photo documentation before and after every job
Natural stone in commercial spaces.
Hotel lobbies, restaurant floors, office entryways. High-traffic stone takes a beating. Pro-Fresh offers scheduled maintenance programs, after-hours service, and restoration scopes for commercial properties. Documentation provided for property management records.
Natural stone surfaces we clean across Houston.
Every stone behaves differently. A method that brightens granite can etch marble in seconds, so we match the chemistry and the pressure to the stone in front of us, not a one-size approach.
Marble
Soft and acid sensitive. Marble shows etch marks and dull spots fast, especially in kitchens and entryways. We use pH-neutral, stone-specific cleaning and finish with honing or polishing where the surface needs the shine brought back.
Travertine
Porous with natural pits that trap grime and old fill. Our travertine cleaning lifts soil out of the holes, refills where needed, and seals so the surface stops drinking in every spill. See our saltillo and porous tile cleaning for related work.
Limestone
Even softer than marble and quick to scratch or stain. Limestone needs gentle, low-abrasion cleaning and the right sealer, since aggressive products open the surface and make staining worse over time.
Slate and flagstone
Common on Houston patios, entries, and pool decks. Slate and flagstone hold dirt in their cleft texture and fade outdoors. We deep clean the surface and re-enrich the color so the stone reads rich again instead of chalky.
Granite, terrazzo, and sandstone
Granite is hard and durable but still benefits from proper cleaning and sealing at the seams. We also clean and restore terrazzo and sandstone, matching the method to each surface so nothing gets stripped or scratched.
Cleaning, honing, polishing, sealing, and restoration explained.
Most companies blur these together and quote one word for five different jobs. Here is what each step actually does, so you know what your stone needs and what you are paying for.
Clean
Lift dirt, grease, and grime out of the stone and grout with stone-specific chemistry. Cleaning removes what sits on and in the surface, but it does not change the finish or repair damage.
Hone
Mechanically smooth the surface to a soft, even matte. Honing removes light scratches and etch marks and is the right call when you want a low-sheen, modern look rather than a mirror.
Polish
Bring the stone up to a reflective shine. Polishing restores the gloss on marble and granite that foot traffic and acid spills have worn flat over the years.
Seal
Apply a penetrating sealer that slows how fast the stone absorbs liquids. Sealing buys you time to wipe spills before they stain, which matters most on porous stone like travertine and limestone.
Restore
The full reset for stone that is etched, scratched, dull, or stained beyond cleaning. Restoration combines honing, polishing, repair, and sealing to bring tired stone back to a like-new finish.
Why Houston humidity is hard on unsealed natural stone.
Our Gulf-Coast climate is humid most of the year, and that moisture is exactly what unsealed, porous stone soaks up. Without a working sealer, stone and the surrounding grout hold dampness, which feeds darkening, mildew, and stubborn stains. Here is how we think about sealing and when it is actually needed.
- Porous stone like travertine, limestone, and sandstone almost always needs sealing in Houston
- Polished granite and marble are denser, so sealing is recommended but less urgent
- Showers, entryways, and patios take the most moisture and benefit most from a fresh seal
- A simple water test tells us whether your current sealer is still doing its job
- If water beads on the surface, the seal is holding and may not need redoing yet
- If water soaks in and darkens the stone, it is time to clean and reseal
- Sealing is best done right after a deep clean, while the surface is open and dry
- A good seal makes everyday cleaning easier and helps spills wipe up before they set
Honest answers to common natural stone cleaning questions.
How often should natural stone floors be professionally cleaned in Houston?
For most homes, a professional clean every 12 to 18 months keeps natural stone floors in good shape. High-traffic areas, kitchens, and entryways may need it sooner. Houston humidity speeds up grime buildup on porous stone, so floors here often benefit from a slightly tighter schedule than drier climates.
What is the difference between natural stone cleaning and restoration?
Cleaning lifts dirt and grime out of the stone and grout without changing the finish. Restoration is a deeper reset for stone that is etched, scratched, dull, or stained beyond cleaning, and it can combine honing, polishing, repair, and sealing. We tell you honestly which one your stone actually needs.
Does Pro-Fresh seal natural stone after cleaning?
Yes, when the stone needs it. Sealing is most important on porous stone like travertine, limestone, and sandstone, and the best time to seal is right after a deep clean while the surface is open and dry. We run a quick water test and only recommend resealing when your current sealer has stopped doing its job.
Is your natural stone cleaning process safe for marble and travertine?
Yes. Marble is acid sensitive and travertine is porous, so both call for pH-neutral, stone-specific chemistry rather than general-purpose cleaners that can etch or dull the surface. We are IICRC-certified and trained in stone care, and we match the method to each surface so nothing gets stripped or damaged.
How do I get a free estimate for natural stone cleaning in Houston?
Call us at (713) 632-4949 or send a few details and photos through our contact and free quote page. We will ask about your stone type, the area, and the condition, then give you a clear estimate. The price we quote is the price you pay, with no teaser rate that jumps on arrival.
Can you clean both indoor and outdoor natural stone surfaces?
Yes. We clean indoor floors, countertops, showers, and entryways, plus outdoor slate and flagstone on patios, walkways, and pool decks. Outdoor stone takes more sun, rain, and humidity, so it often needs color enrichment and a fresh seal to stop it from fading and graying.
Will professional cleaning remove stains and etch marks from my stone floors?
It depends on the stone and what caused the mark. Many surface stains come out with proper cleaning. Etch marks, which are tiny burns in the stone from acidic spills, are not removed by cleaning alone and need honing or polishing to repair. We identify the issue first and tell you up front what cleaning will fix and what calls for restoration.
