Clera does not sub-contract any of its manufacturing processes. We make everything from scratch in our Ontario factory which is why our prices are so competitive and how we are able to produce such consistently good quality products. This allows the customer to choose exactly what they want for their home or business without having to shoehorn their desires into the rigidity of bulk manufactured joinery. We are so confident in what we make that all our units come with a comprehensive whole life warranty and that includes all parts, not just some, and all repairs. You just won’t find better from any other retailer of windows and doors in Windsor.
