What makes Lorimer, Lorimer?

Lorimer is more than just a name. It’s a complete way of doing things, from your initial enquiry to the day the CR Smith van drives away, leaving you with beautiful new windows, doors, or living space to the end of your 10-year guarantee and beyond.

Beautifully shaped windows with slimline frames.

Lorimer windows are like no other window, unmistakeable in design, look and build. Windows are the eyes to your home. They should look natural and well proportioned. Designed to bring in the light, not block it, which is why we have designed the Lorimer frame with its beautiful slim lines.

Beautiful interior timber finishing in every room.

The finished Lorimer window is designed to be looked at, as well as through and there is nothing like the natural beauty of royal oak, natural ash or American cherry sills and surrounds to bring your room to life. We can alternatively offer an engineered wood, finished in brilliant white if this would suit your home better. We’ll oversee every last detail to make sure your home gets the high-quality craftsmanship it deserves, right down to hand finishing the sills in your choice of wax or varnish.
