Family-run VELUX and roof window specialists with over 35 years of trade experience.
AR Windows supports homeowners and commercial customers with VELUX installation, replacement, maintenance, repairs and upgrades, backed by specialist product knowledge and engineers with direct VELUX service experience.
Built around quality products, careful fitting and customer needs.
AR Windows has over 35 years of experience within the trade and is well known throughout the region for supplying and fitting high quality roof window products, as well as paying close attention to what customers actually need from their home or commercial property.
As a family-run business, we take care to provide practical advice, competitive value and a high standard of workmanship. Whether you need a new installation, a replacement VELUX window, maintenance, repair work or an upgrade, our team can help you understand the best route forward.
AR Windows was formed as a result of VELUX Ltd's decision not to offer a replacement or installation service on any of their out-of-warranty roof windows. That created a clear need for specialist support from experienced engineers who understood the products properly and could help customers with practical options.
Our highly skilled engineers have worked directly for VELUX Ltd as Service Engineers for up to 20 years. That background gives AR Windows a strong understanding of VELUX products of different ages, including the types of issues that can affect older roof windows and the options available for repair, replacement, maintenance and upgrades.
AR Windows can carry out a wide range of services for VELUX products of any age, including installation, replacement, maintenance and upgrade services.
This experience means customers receive advice from people who understand the products, the common problems, the practical limitations and the long-term options. In many cases, the right answer may be maintenance or repair. In others, replacement will provide better value and performance over time.
