I purchased two Korniche roof lanterns in June 2019, and while I was initially impressed with their sleek design and apparent build quality, I’ve recently encountered a disappointing issue. The paint on both lanterns has started to bubble and peel, specifically on the aluminium cast parts, which is concerning given the relatively short time they’ve been in service and the premium nature of the product.These lanterns were installed in a well-maintained environment, and I would have expected the finish to withstand the elements for much longer. The deterioration not only affects the visual appeal but also raises serious concerns about the long-term durability and corrosion resistance of the components.I contacted the company that supplied the lanterns on behalf of Korniche and was advised that the issue was covered under warranty. However, when the replacement parts arrived, I was disappointed to find that the protective paint finish was poorly applied — thin coverage, missing paint on the rear surfaces, and visible imperfections where bare material was exposed. It’s no surprise these parts corrode so easily.In my opinion, these components either need to be manufactured from plastic or finished with a high-quality powder coating to ensure longevity. To prevent future issues, I’ve had the replacement parts professionally stripped and powder coated to a standard far superior to the original finish.While I appreciate the warranty support, the quality of the replacement parts and the original finish has left me questioning the long-term reliability of the product.
