About Crystal Windows

Crystal® offers efficient customer support and product after-care.

All Crystal® window and door products come with a comprehensive 10 year "No Quibble" guarantee, meaning that in the event that you suffer problems with our products (aside from accidental breakages) we have a dedicated service team at your disposal along with a comprehensive website FAQ section which will help you to a speedy resolution. (Our No Quibble guarantee extends to other products that we offer although the terms on Garage Doors are different).


Crystal® offers a comprehensive range of PVC-U windows to suit most styles of home and personal tastes including:
Casements, Tilt & Turns, Vertical Sliders, and bays; all combining the latest energy saving technologies, security and ease of operation.


Choose from our comprehensive ranges of: PVC-U Residential moulded panel doors, GRP Composite doors, sliding Patio doors, French Doors and Bifold Doors. In the Crystal® door collection you will find the doors to suit your home and way of life!

Crystal No Quibble Guarantee

We hope you've already got a positive understanding of the kind of company we are and the way we do things! However, we also understand that you need to have absolute confidence in the supplier of your replacement window and door products. To enable you to gain that confidence, Crystal® have a jargon and "small print free" window and door product guarantee:
Ten Year No Quibble Guarantee

If you ever need to have us back to carry out post installation rectification work you'll find we do it willingly and without fuss - because the best sales people we have for Crystal® are the 90,000 (and growing) satisfied customers who know for themselves that we stand by our word and we stand by our workmanship.

In the post installation customer research that we have now conducted for over 6 years, our No Quibble Guarantee always comes out as the most popular feature of Crystal® product and service.
