Joinex Joinery Express Ltd range of timber sash windows combines classic elegance with modern technology. Each unit is hand finished to your exact requirements using only the finest materials and expert craftsmanship.

Did you know that the traditional box sash window has been around since the 17th century? Amazingly the design remains almost unchanged. Traditional sash windows operate via a mechanism that consists of cords and pulleys counterbalanced with weights.

We can replace the entire window or just the sliding parts provided that the existing frames are in good enough condition. The materials we use are of the highest quality.

We are currently working towards FSC certification, which will ensure that all the timber we use is sustainable. Years of experience leave us with the knowledge that only the best and most durable materials are good enough.

All of our new box sash windows are manufactured at our workshop in London by our team of qualified joiners to standards that comply with European manufacturing quality standard.

Unusually for most window manufacturers we make all our own glass double glazed units and cut all our own glass in house. This allows us to maintain the highest standards. We can supply a wide variety of different glass types to suit your specific needs. Patterned, obscure, safety and laminate glass are just a few of the many types available.

Once manufactured and glazed your new box sash windows are carefully painted. Our standard finish is white semi gloss inside and outside consisting of base coat primer / preservative, undercoat and topcoat.

If you require a bespoke finish to your windows this presents no problem. We provide windows with a wide variety of finishes on a daily basis.
