Warranty description

Ten year

Guidance for specification option:

Duco Projects provides 10-year warranty cover on Duco system materials covering potential defects in materials and surface treatment, applicable from the date 3 months after delivery or from the date of installation, whichever is the sooner.For motors and for components subject to wear as a result of movement, however, this warranty is limited to 1 year. This warranty is only valid for building projects in European countries (other countries upon request only) and provided normal use and maintenance have been observed. This warranty is on a sliding scale, reducing by 10% a year (e.g.: during the third year 80% of the claim will still be covered by this warranty). This warranty covers the supply of replacement parts on site to be fitted by the installer, or in the event of defective surface treatment, substantiated costs for pre-treating and recoating the material in question. This warranty relates exclusively to the product itself, not to its installation: accordingly, dismantling and assembly costs are not covered by this warranty. Duco Projects’ maximum liability will be exhausted with the resupply of the defective component or complete system. Under no circumstances can Duco Projects be held liable for any other tangible or intangible loss, including consequential losses. A repaired or resupplied product is covered for the remainder of the warranty period.
