Stone as an architectural element
In the midcentury houses here the stone is rarely just flooring. It runs up a fireplace, forms a feature wall, continues from inside to a patio as a deliberate gesture.
That changes the job in a practical way. Vertical stone and feature walls need different handling from floors, both because gravity works against you and because those surfaces have usually never been cleaned at all.
It also raises the stakes on product choice. Damaging a floor is bad. Damaging the stone wall a house was designed around is considerably worse, and it is exactly the situation where an acidic cleaner does irreversible harm in a single pass.
What sixty years of sealer looks like
On floors of this age the honest finding is frequently that there is no sealer left at all.
Whatever was applied originally wore through decades ago, and the stone has been absorbing ever since. Hard water mineral, desert dust and everything spilled on it have gone into the surface rather than sitting on it, which is why these floors look permanently dull and why mopping achieves nothing.
The good news is that a great deal of that comes back out. Cleaning porous stone that has never been properly cleaned produces one of the more dramatic results in this trade, and then sealing keeps the next sixty years out.
Being careful with an original floor
Worth stating plainly on a page about houses people preserve deliberately.
We do not take anything aggressive to an original stone floor, we do not use products that could alter its appearance without you agreeing to it first, and where color enhancing is a possibility we test a section and let you look before committing anything to the whole floor.
If what your floor genuinely needs is a refinisher, that is what we will tell you. On a significant midcentury house that advice is worth more than the job is.
The chemistry, which is the whole reason this is a separate trade
Travertine, marble and limestone are calcium carbonate. Acid dissolves calcium carbonate. Everything else follows from that one fact.
It means an acidic product does not clean these stones badly, it removes part of the surface, leaving a dull patch where the finish used to be. It happens on contact rather than over time, and there is no route back that does not involve a refinisher and diamond pads.
It also means most of what sits under a kitchen sink is dangerous here. Anything sold for hard water, soap scum or general bathroom use is very likely acidic, and vinegar, which gets recommended constantly, is among the worst.
Everything we put on stone is pH-neutral. There is no circumstance in which that changes.
Worth asking any other company the same question, and treating a vague answer as an answer.
The honest limits
Stone is the one surface where the damage is permanent and expensive, so this belongs near the top rather than in a footnote.
Cleaning and sealing addresses soil, mineral and protection. Cleaning pulls out what has worked into a porous surface, and sealing keeps the next lot from going in. On stone that has never been properly cleaned the difference is substantial.
It does not address etching or worn finish. Etching is where acid has dissolved part of the surface. Worn finish is where traffic has abraded it. Both are changes to the stone itself rather than something sitting on it, so neither cleans off and neither is hidden by sealer.
Putting those right means honing and polishing with diamond pads, which is refinishing. We do not offer it, and when that is what a floor needs we will tell you rather than take the job and leave you disappointed.
How we do it
- Identify the stone and assess the existing sealer. Travertine, marble, limestone and slate each behave differently, and what suits one can harm another. We also establish whether a sealer is present and what state it is in, because that changes the approach entirely.
- Clean with products matched to that stone. pH-neutral throughout, lifting soil and mineral out of the stone and the grout without touching the surface itself.
- Seal, if you have chosen it. Clear to protect what is there, color enhancing to bring the natural color forward, and grout color seal on the lines if you want it.
- Walk the finished floor with you before anything leaves, and explain the cure time for the product used.
Cleaning always precedes sealing. Sealing over soil locks it beneath the coating instead of protecting anything, which is why these are sold as tiers rather than sealing offered alone.
How often to reseal
Reseal every one to two years, depending on the product used and how much traffic the area sees.
There is a test that removes all opinion from it. Put a few drops of water on the stone and leave it five minutes. Beading means the seal is intact. Soaking in and darkening the stone means it has gone, and the stone is now absorbing everything else too.
Most floors we are called to fail that test and the owner had no idea, because a sealer wearing out is invisible until you go looking for it. Full page on resealing.
Questions from Palo Cristi and Sundown Estates
What does it cost in Palo Cristi and Sundown Estates?
Interior: cleaning $1.50/sqft or $1.275 after the 15% off, clean plus clear seal $2 or $1.70, clean plus color enhancing $2.50 or $2.125. Grout color seal takes it to $2.75, $3.25 or $3.75 before the discount. Pool decks are $2, $3 or $4 per sqft. Grout repair from $150, not discounted. $150 minimum per visit.
Is there a Paradise Valley premium?
No. These are the same rates we charge in every town we work in, because the work is the same work. What raises a total here is simply having more stone, which most of these houses do, and you can calculate that yourself from the price list.
What products do you use?
pH-neutral and stone-safe, without exception. Acid dissolves marble, travertine and limestone on contact, so there is no circumstance in which an acidic product touches your floor. It is worth asking anybody else you get a quote from the same question.
Can you remove etch marks?
No. Etching is where acid has dissolved part of the stone surface, so there is nothing sitting there to clean off. Removing it means honing and polishing with diamond pads, which is refinishing and a different trade. We will tell you when that is what a floor needs.
How often should stone be resealed?
Every one to two years depending on the product and the traffic. Put a few drops of water on the stone and wait five minutes. Beading means the seal is working. Soaking in and darkening the stone means it has worn through.
Can you work with our house manager?
Yes, including access, timing and invoicing, plus a written note of what was done and anything we found that will not improve.
