About us
Improving Properties since 1972
Three Generations. One Vision. Uncompromising Quality.
Windowcharm began in 1975 with a simple mission: to deliver high-quality window furnishings with personal service that businesses could rely on. Founded by Leonard Warrilow and now led by his son James, alongside the third generation, Arné, our company has grown with the same values that shaped its early days.
Over nearly five decades, we’ve evolved from a small family business into a trusted name in commercial interior solutions. From blinds and curtains to child-safe fittings, storage systems, and bespoke privacy options, everything we do is built on expertise, craftsmanship, and care.
Operating from our manufacturing base in Sheffield, we combine modern production capabilities with responsive service, maintaining rigorous industry accreditations to ensure safety and compliance at every step. Our in-house teams handle everything, from design and supply to installation and maintenance, so our clients enjoy seamless, worry-free results.
Whether it’s improving learning environments, supporting the NHS, or customising solutions for commercial spaces, Windowcharm stands for reliability, innovation, and relationships that last.
Built on trust. Driven by service. Committed to quality.
