Belgian Limestone Window Sill
Deep, cool blue-gray defines this classic limestone. Its fine, dense grain structure gives it a durability that has made it a staple in North American architecture for well over a century. The thermal finish adds a lightly textured surface, applying controlled heat to bring out a natural, slip-resistant texture while keeping the stone's clean, tailored look. Sized for standard window openings, this sill brings a quiet, understated strength to both traditional and contemporary building exteriors.
Whistler Granite Window Sill
Warm, textured, and quietly traditional. This granite window sill pairs a rock-faced long edge with clean, precision-cut sides, giving you a natural quarried look without the rough sawcut marks that come standard on rougher-cut stone. The beveled edges on the long side and both short sides add a refined finish that sheds water away from the window frame. Its soft, earthy tone works with brick, stucco, and stone facades alike, making it a natural fit for both restoration projects and new construction.
Belgian Limestone Rain Sill
Rich, cool blue-gray defines this classic bluestone stone. Its fine, dense grain gives it the durability that has made it a staple of American window trim for generations. The flamed thermal finish on the top and long side brings out a lightly textured surface that sheds rain cleanly while adding a subtle grip underfoot. Sized to fit standard window openings, this rain sill combines a clean, tailored look with the everyday toughness you want on an exterior detail exposed to weather year-round.
London Granite Window Sill
Cool, silvery blue-gray defines this classic London granite. Its dense, fine-grained structure gives it a strength that holds up for generations, whether it's set into a colonial facade or a modern build. Small flecks of black and white run through the surface, adding depth without pulling attention from the stone's calm, understated color. Sized for standard window openings, this sill brings a clean, tailored look to both traditional and contemporary building exteriors.
Black Basalt Wainscot Sill
Rich charcoal deepens into near-black tones across this striking basalt sill. Its natural, unrefined face brings a raw, quarried texture that reads as bold and grounded rather than polished, with subtle streaks of medium grey running through the darker base color. No grout line needed, this sill sets cleanly against wainscot paneling, brick, stucco, or stone veneer, giving a wall or window opening a crisp, finished edge.
Sunset Slate Wainscot Sill
Rust, pewter green, and black weave together across this multi-color slate wainscot sill, giving it a warm, sunset-like palette that shifts tone depending on the light. Its natural, rockface finish keeps the surface raw and textured, and the stone sets without a grout line for a clean, continuous run along a wainscot wall, window opening, or accent feature. Slate has a long track record in architectural trim, and this piece brings that same durability along with a color range you won't find in single-tone stone.
West Coast Quartzite Wainscot Sill
Warm rust and brown tones weave through streaks of silver-green in this quartzite sill, giving it a natural, earthy character that feels equally at home in a rustic or contemporary build. Its rockface finish keeps a raw, textured surface that catches light differently across each piece, and it sets without a grout line for a clean, continuous look along a wainscot run, window opening, or accent wall. Quartzite ranks among the hardest natural stones available, so this sill holds up well to daily wear while keeping its color and texture for years.
Desert Gold Quartzite Wainscot Sill
Soft beige and light rust blend with subtle sage green streaks across this quartzite wainscot sill, giving it a warm, sun-washed look that pairs well with both natural wood and lighter stucco or brick facades. Its natural, rockface finish keeps the surface textured and raw, and it sets without a grout line for a clean run along a wainscot wall, window opening, or feature wall. Quartzite is one of the hardest natural stones available, so this sill holds its color and edge well over years of everyday use.
