Why choose The Original Box Sash Windows Company?
The original box sash window company established in London (hence the name), came from a passion to see period homes maintained to the highest standards. You won’t find a manufacturer who will care more about creating the perfect sash windows for your home than us. Many of our expert joiners, glaziers and painters have been with the company for ten, twenty and even thirty years, such is the love for their craft.
Lifetime guarantee
All our sash window frames come insured by the Independent Warranty Association (and all glazing units come with a 10-year guarantee too), so you can be just as confident as we are.
Beauty and grace
Our sash windows don’t just glide efficiently in their hardwood frames and keep you safe and warm, but they look just as elegant as they did the day your home was finished.
Mouldings that match
We study the original detailing at your home and create internal mouldings and outside features to match perfectly, so you will uphold its heritage for years to come.
Energy efficiency
Your windows will be flush-sealed and Argon-filled to prevent heat loss, so you can lower your energy bills without ever compromising on authenticity.
Superb security
Your sash windows will be fitted with your choice of multipoint locking mechanisms; from traditional deadlocks to mortice sash-locks and night-latches.
Sustainable sash windows
All our prime, natural African hardwood comes from Forestry Stewardship Council certified sustainable sources. It doesn’t just look good; it makes you feel good too.
Long-lasting and low maintenance
Your sash windows will be finished with high quality microporous paint, for durable, long-term resistance to the elements and easy maintenance.
Bespoke glazing
Enjoy standard double-glazed units with maximised insulation and sound proofing. We will tailor the glazing to your exact requirements, incorporating curved detailing too.
Colour
If you would like a different colour to white? that is no problem. We will make an exterior paint to match your chosen colour.
