Stone Cleaning & Sealing in Boca Raton, FL

What This Service Involves

Stone cleaning and sealing in Boca Raton, FL protects marble, travertine, granite, limestone, and other natural stone surfaces from stains, etching, and wear. Boca Stone Restoration deep-cleans the stone to remove embedded dirt and old sealer, then applies a penetrating sealer that fills the pores and blocks liquids from soaking in. This is the maintenance service that extends the life of your stone and delays the need for full restoration.

Stone cleaning and sealing is a two-step process. First, we deep-clean the stone to remove everything that's on and in it — surface dirt, embedded grime in the pores, old sealer that's broken down, and any organic growth on outdoor surfaces. We use stone-safe, pH-neutral cleaners and pressurized equipment that flushes the pores without etching the surface. No acid-based cleaners, no abrasives.

Once the stone is clean and dry, we apply a penetrating sealer. The sealer soaks into the stone's pores and creates a barrier that repels water and oil-based liquids. It doesn't change the appearance of the stone — no sheen, no color shift, no film on the surface. The sealer works below the surface, which means it doesn't wear off with foot traffic the way a topical coating does.

The whole process is typically a same-day job for most residential surfaces. Floors, countertops, vanities, and outdoor patios can all be cleaned and sealed in one visit. The sealer needs 24 hours to fully cure before the surface sees heavy use, but it's dry to the touch within an hour.

When You Need Stone Cleaning and Sealing

If water stops beading on your stone and starts soaking in, the sealer has worn off. Test it: put a few drops of water on the surface. If they bead up, the sealer is still working. If they spread out and absorb, or if the stone darkens where the water sits, it's time to re-seal.

Visible stains that won't come out with normal cleaning are another sign. These are liquids that have penetrated the pores and can't be reached from the surface. A deep clean can flush some of them out; others need a poultice. Either way, if the stone is staining easily, it's not sealed.

Newly installed stone should be sealed before use. Many installers skip this step or use a low-quality sealer. If your new stone wasn't sealed — or you're not sure — sealing it now prevents the first stain from ever happening. Prevention is cheaper than restoration.

Outdoor stone in South Florida needs re-sealing every 1 to 2 years because UV rays and salt air break down the sealer faster. Indoor stone lasts 3 to 5 years between sealings, depending on traffic and cleaning habits.

Why Problems Happen

Natural stone is porous. Marble, travertine, limestone, even granite to a lesser degree — they all have microscopic channels that absorb liquids. When a liquid hits an unsealed surface, it seeps into those channels. The stone darkens as it absorbs the liquid, and when the liquid dries, whatever was dissolved in it stays in the pore as a stain.

Sealers break down over time. UV light degrades them. Foot traffic wears them. Harsh cleaning chemicals strip them. A sealer that was applied five years ago isn't protecting the stone today — it's worn away, and the pores are open again. That's why re-sealing is a recurring maintenance task, not a one-time fix.

The wrong cleaning products accelerate the problem. Acidic cleaners (vinegar, lemon-based products) etch marble and limestone. Abrasive cleaners (powdered cleansers, scrubbing pads) scratch the surface and open the pores wider. Each cleaning with the wrong product makes the stone more vulnerable to staining. A pH-neutral stone cleaner is the only safe option, and even that works better on a sealed surface.

What Affects Cost

Square footage is the base. Cleaning and sealing is priced per square foot, and most residential jobs — a kitchen floor, a bathroom, a patio — are straightforward. Large commercial spaces or multi-room floors cost more in total but the per-square-foot rate is similar.

The condition of the stone affects the cleaning time. Lightly soiled stone that's been regularly maintained cleans quickly. Stone with years of embedded dirt, old sealer buildup, or organic growth needs more time and possibly multiple cleaning passes. Stripping old sealer before applying new is an extra step if the previous sealer wasn't compatible.

The stone type matters for the sealer choice. Dense stones like granite need a different sealer than porous stones like limestone or travertine. Some stones need two coats; one is enough for others. The sealer cost is built into the price, but the number of coats affects it slightly.

Access and layout add time. Tight bathrooms, kitchens with islands, and outdoor areas with furniture all take longer than an open floor. We move light furniture; heavy pieces need to be moved before we arrive or we work around them.

Sealing vs. Full Restoration

Sealing is maintenance. It protects stone that's in decent condition from future damage. If your stone is clean and flat and the only issue is that it's unsealed or the old sealer has worn off, cleaning and sealing is the right service.

Restoration is for damaged stone. If the surface has deep scratches, etching, lippage, or stains that cleaning won't remove, restoration comes first — then sealing is the final step. Sealing over damage doesn't fix the damage; it just locks it in. Get the stone right, then seal it.

The cost difference is significant. Cleaning and sealing is a fraction of what restoration costs. If you're not sure which you need, we'll tell you honestly after seeing the stone — we don't sell restoration to someone who only needs sealing.
