Stoneman Fabrications templates, fabricates, and installs stone countertops for kitchens, bathrooms, bars, and built-ins across San Francisco and the Peninsula. Since 2007, homeowners, designers, and contractors have trusted our San Mateo team to handle every step of countertop installation, from slab selection to the final seal, so nothing gets lost between companies.
Many countertop projects go wrong in the hand-offs between the slab yard, the fabricator, and the installer. We keep digital templating, waterjet cutting, edge work, and installation in-house, and the same crew that measures your kitchen is the crew that installs it. That means tighter seams, cleaner cutouts, and a countertop that fits the first time.
We install kitchen countertops and islands with waterfall ends and generous overhangs, full-height slab backsplashes, bathroom vanity tops, bar and butler’s pantry tops, and laundry and built-in surfaces. Replacing old countertops on existing cabinets? We remove and haul away the old tops, check your cabinets for level, and install new stone without a full remodel.
We install quartz, granite, quartzite, marble, and porcelain countertops, and we help you match the material to how you actually cook and live. Quartz is the low-maintenance choice, non-porous and never needs sealing. Granite and quartzite bring natural movement and stand up to heavy daily use. Marble offers unmatched character for clients who welcome a lived-in patina. Porcelain handles heat, stains, and sunlight exceptionally well.
San Francisco countertop installation comes with its own challenges: stairs, elevators, tight parking, and HOA move-in rules. We plan for access at the quote stage, from carrying routes to building time windows, so install day goes smoothly and your quote reflects the real job.
Our process is simple. We start with a free in-home consultation and an itemized quote, then help you choose slabs at distributors in South San Francisco and the East Bay. Once your cabinets are set, we digitally template, fabricate in our San Mateo shop, and install. We also coordinate sink and cooktop hookups with your plumber and electrician.
Yes. We remove and haul away the old tops, check that the cabinets are level, and install new stone on your existing cabinetry.
Price depends on the material and slab tier, thickness, edge profile, sink and cooktop cutouts, backsplash or waterfall panels, and site access. Every quote we send is itemized so you can see where the cost goes.
We template after your base cabinets are installed and level, and once you have chosen your sink, faucet, and cooktop. Accurate fixture specs are what make the cutouts fit perfectly.
We plan seam placement around slab size, your layout, the material’s strength, and how the pieces get into your home. We review seam locations with you before fabrication starts.
We have a small showroom and can help you shortlist slabs at the Bay Area’s major distributors in South San Francisco and the East Bay, and we can join you at viewings to check slab sizes and veining.
We install countertops throughout the San Francisco Bay Area. Our shop is in San Mateo, so much of our work is on the Peninsula, but we regularly take on projects well beyond that. If you’re not sure we cover your area, just ask.
