Natural Slate Sills

Slate for window sills can add a beautiful finishing touch to both traditional and contemporary properties. Being either internal or external slate is weatherproof and hard-wearing, they're also simple to fit and once in place can provide years of low-maintenance service.

At Harri James we hand craft the slate to your specifications making it bespoke to you. The sills are all calibrated to thicknesses for ease of installation and better aesthetics. We can cut sills in lengths up to 2.2 meters and where 'jointing' is unavoidable we work to push the slate up close, so that the joint is almost invisible to the eye. Leaving only a hairline joint in place, achieving a beautiful and natural look.

We have a variety of finishes ranging from chamfered, bullnose, mini bullnose, square and aged. The slate has a naturally smooth surface adding quality and durability to any project.
