Cast Stone Sills, Heads & Surrounds

Traditional sills and heads were made of painted wood. These fixtures usually don’t last long, as exposure to the elements causes them to quickly crack and fade. UPVC trim is a modern alternative, but can look too artificial for some people’s tastes.

Cast stone is the perfect solution. Unlike wood or UPVC, it offers the best of both worlds: durability and natural beauty. It is highly resistant to damage, comes in a variety of natural colours, and suits both modern and classic architecture.

At Mexboro, we have our own stone crushing plant and use a mix of aggregates for a natural finish. The end result is virtually indistinguishable from quarried stone, but at a fraction of the cost.

Precast Concrete Sills, Heads & Surrounds

A combination of sand, pebbles, gravel, and cement, precast concrete is sturdy and highly resistant to wear and tear. It’s ideal for projects where appearance is a secondary concern, such as large wall panel units.

Because it uses inexpensive aggregates and doesn’t require surface finishing, precast concrete is a very affordable option.

Mexboro’s precast sills, heads and surrounds use high-quality aggregates and are tested for strength and integrity, ensuring they will last a lifetime.

We can create sills, heads and surrounds of any shape in our pattern and mould-making workshop, from simple lines to the most intricate of designs. This means we can undertake specialist projects that would be too expensive to achieve with natural stone.

Depending on your preference, our sills can either be supplied as straight sections without stooled ends, or with different width stool ends.


Colours and Finishes

Our cast stonework comes in a range of natural stone finishes, including Portland, Hamstone, Bathstone, and Red Sandstone. Thanks to precise pigmentation control, we can change their colours with ease.

For a rustic look, exposed-aggregate finishes are available in natural granite and limestone. Units can be polished to reveal the natural stone face if a more refined style is preferred.

Our precast concrete comes in standard grey, but alternate colours can be manufactured to order. To discuss your requirements, get in touch with us on 01803 558025.
