Our Story

Our history starts more than 30 years ago when John McLeod Ellis decided to take his passion for craftsmanship and joinery and create a business based on offering the highest level of quality and service. Growing from a one man business John steered his love of working with his hands to create London’s leading premium timber sash window and door company.

Having grown up in London, it really made John appreciate the tradition and architectural history the city had to offer. That’s why we have always designed a conservation grade product range which is extremely high performing, while staying true to all the period mouldings and site lines that makes period architecture so special.

John has passed down his beliefs, strengths and skills to his team over the years, including his two sons, Patrick & Jack who now run the day to day operations of the business. The success has largely been down to this highly skilled team who helped to maintain and improve on what John started.

For over three decades, our window workmanship has spoken for itself and withstood every inspection going. With more than 85% of our work being generated from word of mouth and existing customers. From our experience, we know that what we do best is delivering high-levels of quality and service to our customers.

We’re confident we’ll do the same for you.
