Everest Guarantees

It’s because Everest products are innovatively designed, expertly built and rigorously tested that we are able to guarantee each item for longer than any other home improvements company.

At Everest, our quality is assured and our guarantee really means something, offering peace of mind and allowing you to enjoy your purchase for many years to come.

We never expect customers to take our word for it, though.

Instead, we voluntarily push for accreditations with the most neutral bodies in the industry, including the Fenestration Self-Assessment Scheme (FENSA) and the Glass & Glazing Federation (GGF).

Plus, should you sell your property, you can transfer your guarantees to a new property owner, subject to a transfer fee. For transferred lifetime guarantees, we will offer 20-years’ cover from the date of installation for the new owner (25-years for flat roofs).
