10 Year Guarantee

A lifetime of reassurance...

At double the industry standard, Crystal Clear Windows 10 Year Guarantee offers you complete value for money and, crucially, a lifetime of reassurance.

We’re able to offer such a guarantee because our products are designed and manufactured to remain perfectly functional and completely fit for purpose for at least 10 years. Materials and components have been selected for their inherent durability and our manufacturing processes are second to none. It would simply be a waste if products were replaced after only 1, 2 or even 5 years!

It’s also a vital element of Crystal Clear's Environmental Policy. By encouraging homeowners to use their windows and doors for longer, we can help to prevent over consumption and unnecessary carbon emissions.

Let’s face it, windows, doors, conservatories and orangeries are not your everyday purchase and for most they are a considerable financial commitment. But over 10 years our products are a very affordable and truly sound investment that could actually end up paying for themselves when you consider the cost savings you’ll make on your heating bills, as a result of the improved energy efficiency or your home.

Make your house a home! Let Crystal Clear take care of it for you – get in touch with us today and see how we can help.
