Our range of Veka Halo windows, doors and conservatories are manufactured and tested at a state of the art facility in Hampshire and fitted by our own, locally employed installers who have been with us over 10 years.

Your Home Improved

When most of us consider double glazing, we tend to consider three main features. Improved security to help keep our homes safe and sound, an attractive style which will blend with the property and improve its visual appeal, and the heat saving properties which will help reduce our energy bills. But there are other important benefits associated with having double glazed units fitted.

Since 1980, the family firm of Allard Double Glazing has been installing the highest quality double glazed windows, doors, and conservatories in East Grinstead and the surrounding area of Sussex.

Long gone are the days of small panes of glass surrounded by thick, unattractive frames. Our units are available in narrow profile aluminium or upvc frames, and in a large range of styles. From traditional sash windows, to Victorian, Georgian, leaded or unleaded, to modern large clear panes. If you require a flat window style converted to a bay, we can do that as well.

The Highest Quality in All Areas

All our units come with an 'A' rating for energy efficiency, with upgrades available. Home security is a major concern for all of us. All our units have high quality, high security multipoint locking systems, to help make your home as secure as possible. There would be little point in having high energy efficient double glazed units, if the frames were below standard. All our frames are multi-chambered, strong, thermally efficient, environmentally friendly, and produced using colourfast tints.

To back up the quality of our products, we don't use sub-contractors for our installations. All our installers are Certass certificated, and long serving, highly skilled personnel whom we expect to promote our company ethic of providing all our clients with a friendly, professional service, and complete customer satisfaction. All our work comes with a 10 year insurance backed guarantee, which includes all locking systems, handles and hinges.

Our Other Products

If you live in the East Grinstead area of Sussex, and are considering upgrading the old double glazed units you inherited, we offer a complete upvc window replacement service to compliment our full double glazed installations.

Our range of doors includes composite, upvc, and aluminium, in a large range of styles. As with our double glazed window products, our doors are of the highest quality, strong, with high thermal efficiency, and include high security multipoint locking systems as standard.

If you are considering increasing your living space with a conservatory, you've come to the right place. We have a large portfolio of made to measure conservatory styles by leading companies in the industry, or we can design you a completely bespoke conservatory. Available in a range of colours, they have all the benefits of high heat and sound insulation, with multipoint locking on all window units and door.

Whatever your home improvement requirements, whether it's a single replacement window, a complete double glazed refit, or a new conservatory please give us a ring.

We don't employ high pressure salesmen who try to get you to sign on the day. We don't offer silly sales gimmicks that mean absolutely nothing.

What we do offer is honest to goodness advice, quotes which are totally transparent and easy to follow (no hidden extras), products which are of the highest quality and specification, and a friendly professional service by installers who still take a pride in their work.
