We couldn’t have hoped for a better experience.

We had visits and quotes from two companies, but we were impressed by the knowledge of the salesperson and the practical proposal for replacement of our 130 year old sashes whilst retaining our frames. Pricing was at the top end of our budget, but we were very impressed by the results. Our fitter was punctual, polite and very tidy and organised in the way he worked. After each day he left the rooms and access paths clean and tidy. The results are outstanding. We have draught-free, elegant double-glazed windows which are a very close facsimile of the originals. The house is instantly quieter and appreciably warmer. We couldn’t have hoped for a better experience.

This is our second installation with Box Sash windows.

This is our second Installation with the company ( a new front door). The experience was equal to the first. Simon was very punctual and excellent at his care of our home keeping everything to the minimum disruption. We would have no hesitation in recommending the company. First class !!!

Truly Impressive Customer Service & second to none Craftsmanship

Truly impressive customer service and you get what you pay for and more with Box Sash. Quality is assured and the craftsmanship is second to none. We went with Box Sash because we still have mint condition windows installed in 2000 so we knew 20 years on that they were going to be good and we are delighted. You don’t just buy windows but a piece of furniture that complements your period property.
