Lifetime Guarantee

Twenty years; two decades; 240 months; 1,040 weeks, or more than 7,000 days - whichever way you say it, it’s a very long time. A lifetime in fact!

But it’s also how long we guarantee our double glazing windows, doors, conservatories and orangeries for as standard, and at no extra cost to you. At double the industry standard, the Classic Design's Lifetime Guarantee offers you complete value for money and, crucially, a lifetime of reassurance.

We’re able to offer this comprehensive guarantee on a wide range of double glazed windows & doors, conservatories and orangeries because we use only the best UPVC materials and components which have been selected for their inherent durability, and which are proven to withstand the test of time.

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

Value For Money

Let’s face it, windows, doors, conservatories and orangeries are not your everyday purchase and for most people they represent a considerable financial commitment. But over 20 years our products offer fantastic value for money and become a truly sound investment when you consider the cost savings you’ll make on your heating bills as a result of the improved energy efficiency of your home.
