Window Warehouse celebrates 40th anniversary

Window Warehouse proudly celebrates its 40th anniversary in 2026, marking four decades of manufacturing quality windows and doors while remaining true to the family values that have shaped the business since day one.

Founded by Malcolm Cake in 1986, Window Warehouse began as a manufacturer of PVC-U windows and doors in Portsmouth.

From a small team, the company has grown exponentially, supplying installers and customers with an extensive range of PVC-U and aluminium windows, doors and glazing solutions across the South of England.

Throughout its journey, the business has continued to invest in its people, products and facilities while building a reputation for quality, reliability and customer service.

Remi Cake, Managing Director of Window Warehouse, said: “Reaching our 40th anniversary is an incredible milestone and one that everyone connected with Window Warehouse is proud of.

“While we’ve grown significantly since 1986, what hasn’t changed is our commitment to delivering quality products backed by outstanding service.

“Those family values remain at the heart of everything we do, and they continue to shape our ambitions for the future.

“From long-serving team members to new faces, it’s the dedication, hard work and relationships built over the years that have, and will continue to shape who we are as a business.”

As part of the 40-year celebrations during its landmark anniversary, the company recently held a staff summer party and BBQ to celebrate the people who have made the journey possible.

Window Warehouse says it is looking to the future with confidence, continuing to build on four decades of trusted manufacturing while supporting the next generation of trade customers and commercial partners.
