We’re proud to offer a comprehensive guarantee that offers you complete protection and a lifetime of reassurance.


At double the industry standard, the 5 Star Windows, Doors & Conservatories comprehensive 20 Year Guarantee provides you with a level of cover you won’t find anywhere else.

We’re able to offer such a guarantee because our products are designed, manufactured and fitted to last. Our home improvement projects are proven to withstand the test of time.

Our Guarantee


Any associated labour cost with your repair or remedial work will be covered for 10 years. If anything does go wrong in the first decade, it won’t cost you a penny.

After that, labour is chargeable – but any parts or products still covered by the guarantee will be provided free of charge.

Our Guarantee


If there is a problem, please contact us because you’ll invalidate the guarantee if a third party carries out any repairs or modifications. Also, both accidental and environmental damage to your product isn’t covered.

There are a few additional services that fall outside of the standard cover, including plumbing, plastering and any landscaping.  Building work, doors and coloured foils are guaranteed for 10 years.

Our Guarantee


For further details on our guarantee, including a full list of exclusions and exceptions, please contact a member of the 5 Star team who’ll be happy to help.
