Signs Your Natural Stone Needs Professional Cleaning

Many homeowners don't realize how much buildup has settled into their stone until it's professionally cleaned. Common signs include:

Stone that looks dull or worn even after mopping
Visible hard water spots or mineral buildup
Stains that won't lift with regular cleaning
Grout lines between stone that look dark or dirty
A previous sealer that's worn off or no longer beading water
High traffic areas that look noticeably different from the rest of the floor

If your stone floors never seem to look as bright as they should, professional cleaning and sealing may help restore their appearance.

Our Approach to Stone Cleaning & Sealing

Different types of natural stone react differently to cleaning products and sealers, and using the wrong product on the wrong stone can cause etching, discoloration, or other damage that's difficult to reverse. That's why we evaluate your stone's type and condition before recommending a cleaning and sealing approach, rather than applying the same product to every surface.

We'll walk you through the sealing options that make sense for your stone and your goals, whether that's simple protection for the stone, a richer color enhanced finish, or adding grout color seal to any package, and we won't push a higher tier sealer if a basic clean and clear seal is all your stone actually needs.

We use pH-neutral, stone-safe products. No acidic cleaners on natural stone, ever. Acid etches marble, travertine, and limestone on contact, and that damage doesn't undo.

What Cleaning and Sealing Can and Can't Do

Cleaning removes dirt, buildup, and mineral deposits from the stone and grout. Sealing protects what's there and, if you choose the color enhancing option, deepens the natural color.

What it won't fix is etching, the dull spots where something acidic ate into the stone. Wine, citrus, vinegar, and a lot of store-bought cleaners cause it. Etching is damage to the stone surface, not a stain, so cleaning doesn't lift it and sealer doesn't hide it. Same with scratches and worn finish in high traffic lanes.

Fixing those means honing and polishing with diamond pads, which is refinishing work and not something we offer. We stick to cleaning and sealing, and we'll tell you straight if what your floor needs is a refinisher instead.

Pool Decks & Cool Deck

Travertine, flagstone, and cool deck around a pool take a different beating than interior stone. Chlorine, constant wet-dry cycling, calcium from splash-out, and full sun all work on the surface at once.

Cleaning, $2/sqft. Removes algae, calcium, and buildup.

Clean + clear sealer, $3/sqft. Adds stain and weather protection.

Clean + color enhancing sealer, $4/sqft. Deepens the stone color, which makes a faded travertine deck look close to new again.

Sealing a pool deck does more than it does indoors, since there's nothing protecting that stone from the sun and the water otherwise.

Our Stone Cleaning Process

Inspection & Assessment
We inspect your stone's type, condition, and existing sealer to determine the right cleaning and sealing approach.

Professional Cleaning
We use cleaning solutions suited to your specific stone type to lift embedded dirt and buildup without damaging the surface.

Sealing (If Selected)
We apply a clear or color enhancing sealer to the stone, and grout color seal to the grout lines if you've added that option.

Final Walkthrough
After cleaning and sealing, we review the results with you to make sure you're happy with the finish.

What to Expect on Cleaning Day

Appointment length depends on the square footage being cleaned and which sealing options you select, with sealing add-ons naturally taking longer than a cleaning-only service. Sealed areas typically need some time to cure before heavy foot traffic resumes, and we'll let you know the recommended wait time based on the product used.

Why Arizona Homes Need Professional Stone Cleaning & Sealing

Arizona's hard water and desert dust are tough on natural stone specifically, since stone is more porous than tile and absorbs mineral deposits and staining more readily. Unsealed stone is especially vulnerable, and even sealed stone needs periodic resealing as the protective layer wears down over time from foot traffic and cleaning.

Pfaff Cleaning Co. proudly helps homeowners throughout Chandler and the East Valley restore and protect their natural stone with detailed, stone specific cleaning and sealing.

Natural Stone Cleaning & Sealing FAQs

Please reach us at (480) 389-8415 if you cannot find an answer to your question.

Do you move furniture?

We move light furniture like chairs, side tables, and small pieces on request. We don't move appliances, heavy or oversized furniture, or anything with breakables on or inside it. We'll clean right up to and around anything that stays put. If you want those areas done, clear what you can before we arrive.

What types of natural stone do you clean?

We clean travertine, marble, limestone, slate, and other common natural stone flooring. We identify your stone type during inspection and choose products suited to that specific material.

What's the difference between clear sealer and color enhancing sealer?

A clear sealer protects the stone without significantly changing its appearance, while a color enhancing sealer deepens the stone's natural color for a richer, more saturated finish. Both provide protection against staining, but the color enhancing option is a bigger visual change to the surface.

Can grout color seal be added to any package?

Yes, grout color seal is an optional add-on that works with any of our stone cleaning and sealing packages. You're never required to choose a specific tier just to get grout color sealing, so you only pay for what your stone and grout actually need.

Do you offer stone showers or wet areas?

Yes. Stone showers vary a lot by size, condition, and stone type, so text a photo to (480) 389-8415 and we'll give you a rough range. If you're adding grout color seal, we come out to go through color options before booking. One thing to know upfront: shower color seal is not guaranteed. Showers are the hardest surface we seal, and a small number fail early because of moisture or old sealer already behind the tile. Most hold up for years, and sealing runs a few hundred dollars against several thousand to retile, so most people would rather try it knowing the odds.

How often should natural stone be resealed?

This depends on the sealer type and how much foot traffic the area gets, but many homeowners reseal every one to two years to maintain protection. If water no longer beads on the surface, that's usually a sign the seal has worn down.

Can you remove all stains from natural stone?

It depends on the type of stain, how long it's been set, and whether the stone has etched or permanently discolored. Many stains lift significantly with professional cleaning, though some deeply set stains may only improve rather than fully disappear.

Can you remove etch marks or dull spots?

No. Etching is physical damage to the stone surface, so it takes honing and polishing to remove, not cleaning. We don't do stone refinishing. Cleaning and sealing will make the floor look considerably better overall, but etch marks will still be there afterward.

Is stone cleaning safe for pets and children?

Yes, once cleaning and any sealing product has fully cured, the surface is safe for households with pets and kids. We'll let you know the recommended wait time based on the products used.

Do I need to clean before sealing?

Yes, sealing over dirt or grime traps buildup underneath instead of protecting a clean surface, so cleaning always comes first in our process. This is why cleaning and sealing are offered as separate tiers rather than sealing alone.

Can I change my grout to a completely different color?

Yes, our grout color sealing add-on offers over 40 color options, so you're not limited to just restoring your existing grout color. This is a popular option for homeowners looking to refresh the look of their floors without replacing the tile or stone itself.

How much does natural stone cleaning and sealing cost?

Pricing depends on square footage, which stone sealing tier you choose, and whether you add grout color seal. Our instant quote tool gives you a price range in about a minute, and we confirm the exact number at your door before we start.

Do you repair damaged or cracked grout?

Yes, we offer grout repair for cracked or missing grout lines. We evaluate the damage during inspection and let you know what to expect before any work begins.
