Welcome to Box Clever Sash Windows

Hi. Welcome to Box Clever.

Tony Wybrow, Managing Director of Box Clever Sash Windows My 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.

Tony Wybrow
Director

"Fantastic from start to finish! The team fitted 5 sash windows in my home and I’m very happy with the quality of the finish. The team were very professional and it is evident that they are experts in their field and take pride in what they do. There was no pushy sales pitch, instead Simon was very open and honest when presenting options and the price was very competitive. During installation, the team were friendly, tidy and efficient. I highly recommend Box Clever Sash Windows!"

Mr C, Berks, August 2024

"Amazing, friendly, professional service from start to finish. Installed two large Masterframe Bygone range sash windows. Lovely, honest and highly experienced family business who explained the whole process and couldn’t be nicer to deal with. I love my new windows!"

Ms N, London, May 2024

"We chose Box Clever Sash Windows after having a poor experience with another company and I’m so glad we did! Tony and Simon made me feel really comfortable and were great in helping me explore all the options and provided the necessary quotes with no hard sale or pushiness, unlike other companies I had encountered. The whole experience was a breeze. Their communication and responsiveness was faultless and the installation team worked quickly and left the place tidier than they found it! Not to mention, the windows are of great quality and look fantastic too. Would 100% recommend."

Ms C, Hampshire, May 2024

"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

"The team at Box Clever did an amazing job replacing our sash windows. All the work carried out was to the very highest standard, efficient and super tidy too! Can’t recommend them enough."
