About us
Who We Are
MJB TRADING LTD is a family-owned company, trading as Next Generation Sash Windows, with more than a decade of experience in the window industry. We guarantee our work for ten years.
Based in Aylesbury, Buckinghamshire, Next Generation Sash Windows was established in 2020. We specialize in fitting windows primarily in London and within a 60-mile radius of our headquarters.
In addition to delivering high-quality products and great customer service, Next Generation Sash Windows has earned a reputation for excellence in the industry. We offer our clients a full service including technical advice, design, production and installation as well as maintenance of replacement windows and doors. Being amongst the ‘best in class’ and maintaining the highest possible standards for our products is the foundation of our company’s success. We also look after our staff, all of whom work full-time.
The cheapest price may well not buy the best quality product. Windows or doors must be precisely planned and constructed, as well as professionally installed. In any situation, we will try to match any competitor’s pricing on a like-for-like basis.
Please contact us if you have any questions or would like to discuss any projects you are planning. You can reach us by phone, e-mail, or by filling in our contact form below.
