Natural stone can last for generations, but it needs the right care to keep looking new. Stoneman Fabrications provides professional stone sealing and restoration for granite, marble, and quartzite countertops, vanities, and surfaces across San Francisco and the Peninsula. As fabricators who have cut and installed stone since 2007, we know how each material behaves, so we treat your surface according to what it actually is, not with a one-size-fits-all product.
Porous stone absorbs oil, wine, coffee, and water once its seal wears thin. Our stone sealing service starts with a deep clean to remove residue and old sealer, then we apply a penetrating sealer suited to your stone. It protects against staining without changing the color or finish. Quartz is non-porous and never needs sealing, and we will tell you so rather than sell you a service you don’t need.
Marble etches from lemon juice, vinegar, and harsh cleaners, and busy granite counters lose their shine over time. Our granite restoration and marble polishing work hones and repolishes surfaces to remove etching and dull spots, restoring an even finish across the whole top. Deep oil and water stains are drawn out with professional poultices, and chipped edges, hairline cracks, and failing seams are filled, color-matched, and leveled so they are hard to spot.
Every job starts with an inspection. We identify the stone, its finish, and the type of damage, then give you a clear scope and price before any work begins. Most stone sealing, polishing, and stain removal is done on-site in your home, with minimal disruption to your kitchen or bath.
We restore stone wherever it is in the house: kitchen countertops and islands, bathroom vanities, shower walls, tub decks, fireplace surrounds, and floors. Homeowners in San Mateo, Belmont, Burlingame, San Carlos, and San Francisco call us when a surface looks tired, and a restoration is a smart refresh before listing a home for sale.
Before we leave, you get simple care instructions for your specific stone: which cleaners to use, which to avoid, and how to test whether it’s time to reseal. With the right routine, most granite and quartzite only needs resealing every one to three years, and marble stays beautiful with regular care.
It varies by stone. Many kitchen granites benefit from resealing every one to three years. A quick test: if water drops darken the stone within a few minutes, it is time to reseal.
Yes. Etching is surface damage from acids, and we remove it by honing and repolishing the affected area to match the rest of the countertop.
No. Quartz is non-porous and does not need a sealer. Cleaning with a mild soap and avoiding harsh chemicals and direct high heat keeps it looking its best.
Most chips and many cracks can be repaired and color-matched so they are hard to spot. We will tell you honestly if a piece is beyond repair.
Often, yes. We use a professional poultice that draws oil out of the stone over a day or two. Older, deeper stains may need more than one application.
Yes. We restore stone wherever it is in the house, including vanities, shower walls, tub decks, and fireplace surrounds.
