Customer service is imperative to how we run our business and for peace of mind you can be certain that every Sapphire Windows product comes with a 10 year guarantee. We are also a FENSA registered company which means that our products come with an insurance backed warranty. Also, unlike our competitors there will be no deposit required.

We manufacture and install windows and doors in a variety of styles to suit all properties. As well as white you can take advantage of the beautiful wood grain effect finishes or change the appearance of your home even further by adding a splash of colour from our wide selection.
All products have high security locking devices with full multiplying locking systems as standard.
You can feel confident that your windows and doors will stay looking beautiful for longer with very little maintenance and most importantly superb energy efficiency ensuring your home will be well insulated and your bills kept low.
