Marmara

What Marmara does

Marmara Corporation is a Washington, D.C.-based natural stone fabrication and installation company founded in 1985 by Semsi Yozgat, who brings 50 years of industry expertise. The company sources granite, marble, limestone, travertine, onyx, and slate through direct importing channels and operates in-house fabrication capabilities, delivering countertops, bathroom vanities, fireplace surrounds, flooring, and wall cladding. Fabrication turnaround is 2-4 business days after final measurements, with 13 documented edge profile options (Bevelled, Dupont, Full Bullnose, Ogee, etc.) available for customization.

The business operates from a single showroom and warehouse at 1125 Okie Street NE, serving the Washington D.C. metropolitan area (MD, DC, VA only). Revenue is generated through one-time natural stone product sales, custom fabrication services, and professional installation, with quote-based pricing requiring a 50% deposit at the template stage and final payment on installation day. The customer base is hybrid: residential homeowners (primary) visit the showroom for material selection and on-the-spot estimates, while commercial architects and contractors are served through a dedicated senior estimator/project manager (Eduardo Novaes), with named engagements at Clark Construction, HITT Contracting, Balfour Beatty Construction, and Sheraton National Hotel.

Distribution is direct: showroom visits, phone sales, and a website contact form. The company is privately held by its founder with no external investment, no M&A activity, and no public listing. Marketing relies on the company website (marmarausa.com), Instagram (@marmaracorp), showroom traffic, and customer referrals within the DC metro market. The company holds multiple regional industry awards (specific names undisclosed in source material) and operates as a fully insured and bonded stone contractor.

Broad incumbents

• Daltile: Major tile and natural stone manufacturer/distributor (Mohawk Industries subsidiary) supplying flooring, wall tile, and countertop stone across residential and commercial channels. Competes with Marmara in flooring, wall cladding, and stone surfacing product categories.
• Cambria: American-made quartz and stone surface manufacturer with broad dealer distribution. Comparable to Marmara in the residential kitchen/bath countertop category and increasingly relevant as quartz substitutes for natural marble and granite in many of the same customer projects.
• Levantina: Spanish multinational natural stone supplier operating quarries and distribution for marble, granite, and limestone surfacing products globally. Adjacent peer that supplies the same raw stone materials Marmara fabricates and competes indirectly for large commercial stone contracts.
• Cosentino: Global stone surface manufacturer offering Silestone (quartz), Dekton (ultracompact), and natural stone Sensa. While Marmara fabricates natural stone regionally, Cosentino competes for the same countertop specification in commercial and high-end residential projects, with a vastly larger portfolio and dealer network.
• MSI Surfaces: Large North American distributor and fabricator of natural stone, quartz, and porcelain surfacing products with showrooms nationwide. MSI is a broad competitor to Marmara in stone countertop and tile supply, operating at significantly greater scale and geography.
• Antolini: Italian natural stone processor offering exclusive marble and stone collections with distribution into luxury residential and commercial projects. Adjacent peer whose high-end natural stone selection competes for the same premium specifier and architect relationships Marmara cultivates in DC.
• Caesarstone: Leading engineered quartz surface manufacturer competing with natural stone in kitchen and bath countertop applications. Comparable to Marmara as an upstream surfacing supplier specified into the same residential and commercial project types the company serves in the DC metro.

Emerging players

• Marble.com: Online-first natural stone countertop retailer offering templating and installation services across multiple U.S. metros. Comparable to Marmara as a stone countertop supplier but competes via digital ordering and broader geographic reach rather than a single regional showroom.

Direct peers

• Coldspring: Natural stone quarrier and fabricator producing granite, marble, limestone, and architectural stone for commercial building and memorial projects. Closest direct comparator to Marmara in the custom dimension-stone fabrication and commercial installation business model.
• Polycor: North American natural stone quarrier and fabricator offering granite, marble, limestone, and soapstone for architectural and building applications. Shares Marmara's vertical integration from quarry through fabricated stone products serving construction specifiers.
