The business, Cerralumin, is a manufacturer and expert in aluminum and PVC window installations, motorized blinds, closures, and roofs. They offer customized solutions with 36 years of experience backing them up. The company is certified with European standards and provides a warranty on their aluminum windows.The services include PVC Windows, Superior Quality Service, Aluminum Windows, Aluminum Glazing, Motorized Blinds, Closures, and Roofs. They are open Monday to Friday from 9:00 AM to 6:00 PM.However, there are some issues with the business. The first one is that they do not provide a guarantee, and the post-venta service is not reliable. One customer had to wait for months to get a response, and when they finally did, it was just a promise to send a note. Another customer had a similar experience, waiting for 5 months to get a solution to a problem with their installation.Additionally, there have been reports of poor quality work. One customer mentioned that the installation was a "chapuza" (a mess), and another customer had to wait for months to get a response to a problem with their installation.Despite these issues, the business has received positive reviews from some customers. They have been praised for their professionalism, quality of work, and good prices. However, it seems that the company's response to customer complaints is lacking.Overall, Cerralumin seems like a business that is struggling to balance quality and customer service. While they have some good qualities, the issues with their post-venta service and poor quality work make them a risk to work with.
