Why slate and stone need professional care
Slate, flagstone, quartzite and similar stones are tough, but they are also textured and porous. Dirt settles into the clefts and pores, algae and mildew grow in the joints, and whatever sealer was applied years ago breaks down into a gray film. Pressure washing blasts the surface without reaching into the stone and can erode the joints.
Proper cleaning uses stone-safe chemicals and hand agitation to lift dirt out of the texture, followed by a rinse and extraction that removes it. Then the stone is sealed so the result lasts.
Natural look or color enhanced?
This is the main choice, and we do a test spot during the free estimate so you can see both on your own stone.
| Factor | Natural sealer | Color enhancer |
|---|---|---|
| Appearance | Invisible. Stone looks clean and dry. | Deepens color. Stone looks rich and wet. |
| Best on | Light stone, honed finishes | Slate, flagstone, travertine, dark stone |
| Protection | Repels water and stains | Repels water and stains |
| Traction | Unchanged | Unchanged |
Both are penetrating sealers, so neither leaves a film that peels or makes a patio slippery.
Indoor stone floors
Slate and stone entries, kitchens and great rooms collect grit that dulls the surface and dirt that settles into the texture. We deep clean, treat any efflorescence, and seal. Indoors, a sealer typically lasts two to three years before the stone starts absorbing water again.
Patios, pool decks and walkways
Outdoor stone in South Florida fights sun, rain and constant humidity. Algae and mildew turn travertine pavers and flagstone dark and slick. We clean and treat the growth, rinse, let the surface dry, and seal with a penetrating sealer that sheds water. Outdoors, plan on resealing every year or two.
Not sure what kind of stone you have?
Stone that was once polished and has gone dull, such as marble, polished travertine or terrazzo, needs honing and polishing rather than cleaning. If you are not sure which you have, send a photo or just call. We will tell you during the free estimate and quote the right service.
