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.
