I wanted to praise Viwinco for their warranty and customer support. I had one window crack and two others where the seals were compromised. They covered the materials under warranty.I had the option of using someone local or having factory-direct technicians do the work. I opted to have the factory-direct technicians handle it because, IMHO, they know the windows best. The cost was reasonable, and the technicians—Ray, Boe, and Rian—were amazing.They confirmed the appointment the day before and also let me know when they were close to arriving. They were fast, clean, and friendly. I also asked them to adjust a slider for me, and they were happy to help with a few other questions I had.I highly recommend Viwinco products and their factory-direct technicians. It’s refreshing to see a company stand behind its products and provide this level of customer service.
