Serving New Canaan, CT · From our Bridgeport shop
CMG — Cornerstone Marble & Granite — fabricates marble, quartzite, granite, quartz, porcelain and soapstone in our Bridgeport shop, about thirty-five minutes from New Canaan via the Merritt. Homeowners and designers are welcome at the slab yard to tag material in person before a single cut is made.

New Canaan builds — modern glass and classic shingle alike — ask for stone that holds its own: bookmatched marble, quartzite with movement, honed finishes, mitred waterfall edges and full-height slab backsplashes. We cut everything in-house, dry-fit waterfall mitres before glue-up, and carry veining around corners so the finished piece reads as one stone.
For projects near New Canaan Center, Silvermine and Ponus Ridge, we coordinate templating around the cabinet installation, plan seams before cutting, and complete most countertop installations in a single day.
Choose your slabs at the yard — sequential slabs if the job needs veining to flow across island and perimeter. We digitally template once cabinets are set, fabricate in-house, and install. Template to install typically runs one to two weeks.
Trade clients: we work from architects' and kitchen designers' drawings, flag seam placement before cutting, and send layout photos for approval on bookmatched work.
The showroom and slab yard at 46 Beatrice St, Bridgeport is open by appointment — about thirty-five minutes from New Canaan. Call 914-575-1705 or email hello@cmgstones.com.
