The Best Hardwood Windows and Doors since 1979

Here at The Original Box Sash Windows Company we’ve helped protect and prolong the beauty of period homes and streets for more than 40years 

 

Since our earliest days in London we’ve supplied top quality windows and doors to thousands of town and country properties that still look fabulous today.

Beautiful, solid and expertly fitted, what we make, lasts and with our lifetime guarantee customers come back to us time and time again. Hardwood timber windows, French doors, bi-fold doors and front doors, we do it all.

As the company who developed double glazed timber sash windows, we’re justifiably leaders in the marketplace, so when you choose us you can be sure you’re choosing the best. Indeed we’re so confident of our craftsmenship we encourage our customers to visit our factory and see their windows and doors being made (we’ll even buy a yummy lunch or dinner afterwards!). 

We operate across the southern half of the UK, predominantly in London, Surrey, Hertfordshire, Berkshire, Buckinghamshire, Hampshire, Sussex, Bedfordshire, Oxfordshire, Cambridgeshire, Essex, Gloucestershire, Wiltshire, Suffolk.

Creating something beautiful from wood is a passion and the team are rightly proud of everything we make.

The Process  – Everything is bespoke and made to order in a traditional yet environmentally friendly manner. From cutting, joinery, painting, glazing and finishing – no chemicals are used in the manufacturing process. Nothing is wasted – even the sawdust we collate through our dust extraction system is given to the local stables to make bedding for their horses.

Wood – When you’ve been making windows and doors for as long as we have – you know what works best. We use sustainably sourced Idigbo wood from Africa, an exceptional quality timber that’s similar in appearance to Oak. Easy to work with it doesn’t warp and is resistance to water and termites – which have been recently found in England for the very first time – and is more durable than modern engineered woods that over the years can deteriorate, particular from moisture retention. Little wonder our frames carry a lifetime guarantee.

Glazing  – We make our own units from scratch because we couldn’t find a reliable source to produce them consistently to our own exacting standards. That way we can control the quality from start to finish (which we prefer!) Glazing spaces are always filled Argon gas for maximum insulation and sound proofing properties.

Ironmongery  – A wide choice of solid metal fittings in varying colours and finishes, which our surveyor will show you.

Paint  – A microporous water based paint with a white satin finish and 70% sheen comes as standard. Feeling more adventurous? We can colour match shades such as a Farrow and Ball with tailored and sprayable exterior paints produced for us by Morrell Paints.

Fitting – Our fitting team are experienced, tidy, friendly and helpful and naturally operate to all current COVID19 Safety Standards.
