Welcome to Box Clever Sash Windows

A family run business - dedicated to installing the finest windows and doors for period properties.

Hi. Welcome to Box Clever.

Tony Wybrow, Managing Director of Box Clever Sash WindowsMy name is Tony Wybrow and for the past 22 years I have been dedicated to sliding sash and period style windows and doors - installing the finest quality products available - with an absolute passion for their design, elegance and quintessentially English style.

During that time there have been huge developments in the design, quality and performance of the frames available –the woodfinish PVCu ‘timber alternative’ ranges have made major advances in style and detailing meaning that they are now commonly accepted in Conservation Areas whilst there has been a big shift to high performance Engineered timber products that don’t ‘cost the Earth’.

As a family run company, here at Box Clever, we have assembled a professional and knowledgeable team - from offering honest, tailored advice on product options, to our experienced, specialist installers - approachable, efficient and taking great pride in their work.

Have a look at our gallery to see the size and diversity of projects we’ve been involved with and see some of the comments our customers have sent us.

I look forward to hearing from you to see if we can help with your project.

"Please thank Tony and ALL TEAM, the lads are such a pleasure to have working in the house and the workmanship is better than we expected. Tony and Syreeta make everything so easy, we cannot recommend you enough."

Mr P, Berkshire, March 2024

"I cannot fault the experience in any way with Box Clever Sash Windows. From the outset, Tony and Syreeta were so accommodating from being very responsive, answering all our questions and meeting to our requirements. [..] Simon and the install team ensured that any space where they were working was properly protected and I was so impressed that there was no mess at all where work had been carried out. [..] I have more work to do in the future and will be for sure be using Box Clever Sash Windows again. Thanks Team!"

Mr D, Berkshire, March 2024

"Thanks to you and all the team: I've met a number of the installers over time but Lewis and Simon have probably done the most and always been exemplary in their manner and how they engaged with me."

Mr E, North Hampshire, February 2024

"We had decided to use Box Clever right from the beginning when Tony came round and gave us our quote. After getting quotes from 4 other company’s they were the only one that listened to what I wanted. The installation team, Lewis and Simon, were so considerate and tidy when working in the house and each window was installed and finished with the same time, care and high standard. I would highly recommend using them."

Ms H, Berkshire, Jan 2024

"We are so pleased with the windows – immediately see the difference with keeping the heat in over the recent cold snap. They look lovely and work better than we hoped for. Really successful. The install was complex, but the boys were great. Do pass on our thanks to the team and Syreeta in the office."

Mr S, West London, Jan 2024

"I'm really happy with the windows and French Doors - they make such a difference to the house. The guys did a great job fitting them (and tidying up afterwards too!)."

Ms Q, Berkshire, Dec 2023

"Over the last 3 years I have used many trades to complete renovations and extensions to my house. While most were good, there are few I would wholeheartedly recommend to a friend. Box Clever Windows is an exception. The installation was completed to a very high standard by an excellent team of fitters, not only would I recommend them to a friend, I already have!"
