The Stone Brothers

What The Stone Brothers does

The Stone Brothers is a privately held countertop fabrication and installation firm headquartered in Woodinville, Washington, founded in 2006. The company operates a combined showroom and manufacturing facility at 7533 W Bostian Rd Bldg B, where customers can view full stone slabs before purchase. It sells and installs natural and engineered stone surfaces — quartz, granite, marble, quartzite, porcelain, and sintered stone — for kitchen countertops, bathroom vanities, backsplashes, shower walls, and fireplaces. Complementary offerings include kitchen and bathroom sinks from brands such as Kraus, Karran, Kohler, Sharp Sinks, and MSI.

The business serves three primary customer segments: residential homeowners (the primary segment), home builders and contractors via the Square-Foot Program — a curated quartz offering with volume pricing for new construction — and commercial designers, architects, and casework companies across the Puget Sound region. The commercial-motion is supported by PPE-trained installation crews and an emphasis on safety compliance and on-time project completion. GTM is sales-led and showroom-driven, with digital channels (website, local SEO across 10+ Puget Sound cities, Instagram, Facebook, Houzz) feeding top-of-funnel awareness.

The revenue model is project-based and one-time per installation. Pricing is quote-based and not publicly disclosed; the Square-Foot Program introduces volume pricing for builders and contractors. The company employs 8 people, has no institutional investors, no parent company, and no disclosed funding. Geographic reach is limited to the Puget Sound region, with named service areas including Seattle, Bothell, Bellevue, Mill Creek, Redmond, Kenmore, Issaquah, Kirkland, Sammamish, and Snohomish.
