Manufacturing windowsills for over 3 decades, Sanderson Concrete has become the gold standard for architectural precast concrete trim. With precast on virtually every corner of every city in the Lower Mainland and throughout BC, Sanderson Concrete produces thousands of windowsills, lintels, caps and coping annually. Small sills, bull-nosed sills, curved cast stone arches on a curved building or lintels spanning over 25’ in length, our in-house mould shops can manufacture forms that are straight, true and consistent every time. Our fabrication and design team’s attention to detail ensures masons a trouble free installation with consistent finishes and edges that are tight and uniform, drip lines that are straight and true – and precast concrete with a minimum of bug holes.
Western Canada’s Largest Sill & Lintel Manufacturer
Producing thousands of windowsills annually, Sanderson Concrete is Western Canada’s largest manufacturer of precast concrete windowsills and architectural trim.
Sills, lintels, wall coping and post caps are a large part of our daily production. From simple grey sloped sills to tapered sills with upstands, end dams – or shoulders – we have been making windowsills and lintels for over 30 years and have produced architectural precast elements for buildings across North America.
Wood, Steel, and Rubber Forms
Our three in-house mould shops ensure our architectural and masonry clients exacting details in our formwork – and everything starts with formwork. From simple straight forms to intricate curves and end dams – our windowsills are the first choice for masons who know that quality is an important reflection on the masons own work. Like a good trowel – good precast pays for itself.
