Marble and stone window sills — measured, cut and installed

Why it works

A window sill has to cope with direct sun, temperature swings and sometimes moisture. That is why we usually recommend granite, quartz or porcelain rather than a light marble that stains easily. We fabricate with a drip groove under the front edge, which stops rainwater running down the wall and leaving streaks.
