There are a few restrictions on your Clearview cover, including accidental and environmental damage. It’s important to keep your products in a good state of repair and if faults are found due to neglect or vandalism, these will not be covered either. Similarly, if another company undertakes any modifications or work on a Clearview-installed product, that will invalidate the warranty.
There are a few extras that are covered for five years and therefore excluded from the full 20-year cover, including plumbing, plastering, electrics, timber boxing and foils. Base building works and aluminium windows and doors are covered for ten years.
